Unknown Star System

The stars stretched in silent, patient lines across the forward viewport, familiar and distant against the steady hum of the Enterprise-D’s engines.

“Captain’s log, stardate 47892.4. The Enterprise has diverted from its scheduled survey of the Ormendin trade corridor after long-range telemetry from our newly upgraded lateral sensor arrays detected anomalous readings from an uncharted region near the edge of Federation-mapped space.”

Captain Jean-Luc Picard stood beside his command chair, one hand resting lightly along the polished rail, his gaze fixed on the stars ahead.

“Initial sensor analysis suggests the presence of a previously unknown star system. Preliminary scans indicate several small rocky bodies orbiting close to the primary star, with multiple gas giants positioned along the system’s outer edge. While such a configuration is not uncommon, the readings themselves remain inconsistent with any stellar formation currently on record.”

He paused, his expression thoughtful.

“Commander Data has requested permission to conduct a more detailed investigation. Given the unusual nature of the sensor returns, and the opportunity to test the expanded range of our new sensor systems, I have authorized a brief deviation from our assigned course.”

Picard looked toward the viewscreen.

“We are proceeding at warp six.”

He lowered his hand.

“Computer, end log.”

A soft chirp answered him.

The bridge of the Enterprise carried on in its usual composed rhythm. Consoles glowed softly. Officers worked with quiet precision. The low pulse of the ship’s systems filled the spaces between words.

At the operations station, Lieutenant Commander Data’s fingers moved swiftly over his console.

“Captain,” Data said, turning slightly in his chair, “we are now within optimal sensor range of the star system.”

Picard stepped toward the center of the bridge. “Very well, Mister Data. Begin your scans.”

“Aye, sir.”

Riker sat forward in the first officer’s chair. “Any sign of ships?”

“Negative, Commander,” Data replied. “I am detecting no warp signatures, no impulse trails, and no artificial subspace emissions.”

Worf looked down at tactical. “No weapons signatures. No defensive grids. No orbital platforms.”

“That seems unusually quiet,” Riker said, “for a system giving off readings strong enough to pull us off course.”

“Agreed,” Data said. “The anomalous readings remain present, but they are not consistent with conventional technology.”

Picard glanced toward him. “Explain.”

Data studied the information passing across his screen.

“The readings appear to be distributed across the system itself. Each major celestial body is emitting a faint power signature.”

Troi turned from her seat beside Riker. “Each one?”

“Yes, Counselor. The star, the inner planets, the outer gas giants, and several larger moons all appear to possess some form of residual energy output.”

Riker frowned. “Power signatures from planets and moons?”

“That is correct,” Data said. “However, the signatures are extremely faint. They do not correspond to fusion reactors, geothermal taps, antimatter systems, or any form of power generation known to the Federation.”

Picard’s expression tightened with interest. “Could it be natural?”

“I cannot rule out that possibility,” Data replied. “However, the uniformity of the readings is unusual. Each body displays a variation of the same underlying energy pattern.”

The turbolift doors opened.

Geordi La Forge stepped onto the bridge, already holding a padd in one hand.

“Captain, Engineering has been monitoring those readings through the sensor upgrades. Whatever they are, they’re subtle. If we were using the old arrays, we might have passed right by and never noticed them.”

Picard turned. “Your assessment, Mister La Forge?”

Geordi moved down the ramp toward the command area. “I don’t know yet. At first I thought we were looking at background interference, maybe some kind of harmonic reflection off the system’s gravity wells. But the signatures are too orderly. They’re not random.”

“Could someone be hiding there?” Riker asked.

Geordi hesitated. “If they are, they’re doing it better than anyone I’ve ever seen.”

Data’s console chirped.

“We are now entering the outer boundary of the system,” he said.

“On screen,” Picard ordered.

The starfield shifted.

A yellow sun appeared at the center of the display, bright and steady. Around it, the computer overlaid a series of faint orbital paths. Small icons marked planets, moons, and asteroid belts as the Enterprise’s sensors identified them one by one.

Picard studied the image.

At first, nothing about it seemed remarkable.

Then Data went very still.

Riker noticed. “Data?”

The android did not immediately answer.

His fingers moved again, faster now.

“Captain,” Data said, “the configuration of this system is… familiar.”

Picard turned toward him. “Familiar in what way?”

Data touched another control.

The display shifted. A second orbital diagram appeared beside the first, this one drawn from the Federation astronomical database.

For a moment, the bridge was silent.

The two images matched.

Not approximately.

Exactly.

Riker rose slowly from his chair.

“That’s Sol.”

“Yes, Commander,” Data said. “The primary star matches the mass, spectral output, and relative position of Earth’s sun. The inner planetary bodies correspond to Mercury, Venus, Earth, and Mars. The asteroid belt is present at the expected distance. The outer planets correspond to Jupiter, Saturn, Uranus, and Neptune.”

Worf looked sharply at the screen. “That is impossible. We are nowhere near Sector 001.”

“No,” Data said. “Our current position is approximately seven hundred and forty-two light-years from Sol.”

Geordi looked down at the padd in his hand, then back to the screen. “That can’t be a coincidence.”

“No,” Picard said quietly. “It cannot.”

Troi looked unsettled. “Could it be a simulation? Some kind of projection?”

Data answered without turning. “The gravitational readings are genuine. The star is exerting appropriate gravitational influence on all detected bodies. The planets possess mass, atmospheres, magnetic fields, and orbital momentum consistent with physical objects.”

Riker folded his arms. “So we’ve found a second Sol system.”

“That would appear to be the case,” Data said.

Picard stepped closer to the viewscreen. “Magnify the third planet.”

The display shifted again.

A blue-white world filled the screen.

Earth.

Clouds swirled over blue oceans. Brown and green continents emerged beneath them. The polar ice caps gleamed in the sunlight. The shape of Africa was unmistakable. Europe. Asia. The curve of the Americas rotating slowly into view.

Picard said nothing.

For a moment, he did not move.

The bridge crew stared at the impossible planet hanging before them.

Riker broke the silence first. His voice was lower than usual.

“That’s Earth.”

Data’s head tilted slightly. “It is an exact visual match for Earth, Commander. Atmospheric composition, planetary diameter, axial tilt, lunar distance, oceanic coverage, and continental distribution all correspond to Federation records.”

Worf’s hands moved over tactical. “I am detecting satellites in orbit.”

Picard turned slightly. “Weapons platforms?”

“No,” Worf said. “Primitive communication satellites. Weather observation satellites. Some orbital debris. Nothing more advanced.”

Geordi let out a quiet breath. “No orbital shipyards. No defense grid. No spacedocks.”

“No moonbase,” Riker added.

“No detectable settlements on Luna,” Data confirmed. “No structures on Mars. No colonies. No subspace activity. No warp signatures anywhere in the system.”

Picard looked back to the screen. “And the anomalous power readings?”

“Still present,” Data said. “Every major celestial body in the system continues to emit the same faint signature.”

“Could the population be responsible?” Troi asked.

Data adjusted the scan. “I am unable to determine a connection. The energy readings are not strongest on the inhabited planet. In fact, Jupiter’s moons are producing a slightly higher aggregate signature than Earth.”

“Are any of those moons inhabited?” Picard asked.

“Negative. There is no evidence of habitation on any moon or planet other than Earth.”

Riker looked over Data’s shoulder. “What about Earth itself?”

Data began a full planetary scan.

The bridge waited in tense silence.

“Population estimate,” Data said at last, “approximately six billion.”

Troi turned slowly toward the viewscreen. “Six billion people.”

“Technological level?” Picard asked.

“Late industrial to early information age,” Data replied. “Widespread electrical infrastructure. Radio and television transmissions. Computer networks. Internal combustion vehicles. Nuclear fission power. Limited orbital capability.”

Geordi looked up from his padd. “That sounds like Earth before First Contact.”

Picard’s expression hardened slightly. “Can you determine the date?”

“I will attempt to access one of the communication satellites,” Data said.

Riker looked concerned. “Without being detected?”

“Their technology is not capable of detecting our intrusion, provided I limit the transmission strength and use passive signal interpretation wherever possible.”

Picard nodded. “Proceed, Mister Data. Quietly.”

Data turned back to his console.

On the viewscreen, Earth continued to rotate, unaware of the starship watching from above.

For several seconds, the only sound was the muted chirp of Data’s controls.

“I have accessed a low-power communications relay,” Data said. “It appears to be linked to terrestrial broadcast and data networks.”

Geordi moved closer. “Can you translate the formatting?”

“Yes. The data architecture is primitive, but decipherable.”

Riker gave a faint smile despite himself. “I’m not sure the people of the twentieth century would appreciate hearing their computer systems called primitive.”

“I did not intend offense,” Data said. “It is an accurate technical description.”

Picard’s mouth twitched, but only briefly. His eyes remained on the planet.

Data continued working.

“I have located multiple date references in broadcast signals and network traffic. Cross-checking calendars, news transmissions, and satellite timestamps.”

He paused.

“The current Earth calendar date is September 1, 1999.”

The bridge went very still.

Riker’s smile faded.

“1999,” he repeated.

Troi looked from Data to Picard. “Nearly four hundred years ago.”

“Three hundred seventy-six years, ten months, and approximately twenty-four days prior to the current date by the Earth calendar,” Data said.

Riker glanced at him. “Thank you, Data.”

“You are welcome, sir.”

Picard turned away from the screen and moved slowly toward the command area.

“Options.”

Geordi spoke first. “Temporal anomaly. Maybe the whole system is displaced from the past.”

Data turned slightly. “There is no evidence to support that hypothesis. The Enterprise experienced no temporal displacement upon entering the system.”

Riker looked at him. “Would we necessarily know?”

“Yes, Commander. The ship’s chronometers remained synchronized with the Federation timebase. We detected no chroniton surge, no tachyon flux, no quantum phase distortion, and no measurable discontinuity in local spacetime.”

Worf’s brow furrowed. “Could we have traveled back in time without detecting it?”

“That is highly unlikely,” Data said.

Picard looked at him carefully. “But not impossible.”

“No, sir. Not impossible. However, I have verified our navigational position against nearby pulsars, quasars, and deep-space reference points. They are all consistent with our expected location in the current century.”

Riker frowned. “What about Starfleet?”

Data’s fingers moved again.

“We still have a subspace uplink through relay beacon seven-one-nine. I am receiving current navigational updates from Starfleet cartography and a data exchange from the Daystrom Institute. Both confirm the present stardate.”

Geordi looked back to the planet. “So we’re in the right time.”

“Yes,” Data said.

“And the wrong place,” Riker said.

“Also yes.”

Picard folded his hands behind his back. “Or perhaps we are in the right place, and the system is the wrong one.”

Troi looked toward him. “A duplicate.”

Picard nodded slightly. “A duplicate of Sol. Complete with Earth, Luna, the other planets, and six billion people living in the year 1999.”

Worf’s expression darkened. “That would require power beyond anything known to the Federation.”

“Beyond the Q?” Riker asked.

No one answered immediately.

Picard turned toward Data. “Could this be an illusion generated for our benefit?”

“Possible,” Data said. “However, if so, it is a highly sophisticated one. The planet’s electromagnetic emissions contain millions of independent transmissions in multiple languages. Weather systems are dynamic. Ocean currents, tectonic activity, biological readings, and human activity all appear internally consistent.”

Geordi nodded slowly. “If it’s a fake, it’s perfect down to the noise in the power grids.”

“And the people?” Troi asked quietly.

Data looked at her. “The lifesigns are real, Counselor. Or they are being simulated at a level indistinguishable from reality.”

Troi’s eyes returned to the planet.

“I can sense them,” she said.

The others turned toward her.

She looked almost overwhelmed. “Not clearly, not at this distance. But there are minds down there. So many. Fear, anger, joy, grief, hope. It feels like Earth.”

Picard absorbed that in silence.

Riker stepped down beside him. “Captain, if this is Earth in 1999, the Prime Directive—”

“Would apply,” Picard finished.

Riker nodded. “And so would the Temporal Prime Directive.”

Picard looked at him. “If this is, in fact, Earth’s past.”

Data turned from ops. “Captain, by all available evidence, it is not.”

The bridge fell silent again.

Picard regarded Data.

“Explain.”

Data rose from his chair and faced him fully.

“We did not experience a temporal shift. Our chronometers remain accurate. Our uplink with the Daystrom Institute remains active and confirms the current stardate. Stellar reference points outside this system correspond to the twenty-fourth century. Therefore, by all logical analysis, we are not in orbit of Earth nearly four hundred years in the past.”

He turned slightly toward the viewscreen.

“We are in orbit of an object that is, in every measurable way, Earth as it existed on September 1, 1999.”

Geordi shook his head. “That doesn’t make me feel better.”

“No,” Data said. “Nor was it intended to.”

Worf checked tactical again. His posture shifted.

“Captain.”

Picard looked back. “Report.”

“We are being scanned.”

Riker’s head turned sharply toward tactical. “By Earth?”

“I cannot identify the source,” Worf said. “The scan is weak by our standards, but highly focused.”

Data returned to his station, his hands moving across the console.

“It does not match any known twentieth-century scanning technology,” he said.

Geordi moved toward the engineering station. “Their satellites shouldn’t even know we’re here, much less be able to get a coherent scan through our shields.”

“They don’t,” Worf said. “The orbital satellites remain inactive toward us.”

Picard stepped toward tactical. “Could the scan be coming from somewhere else in the system?”

“Negative,” Data said. “I am isolating the beam now.”

The bridge lights dimmed slightly as the computer rerouted additional processing power to ops.

On the viewscreen, the image shifted from Earth in orbit to a map of the northern hemisphere. Lines of data flickered rapidly across the display. The image tightened over Europe, then the British Isles, then southern England.

Data’s fingers paused.

“The scanning signal originates on the surface of Earth.”

Riker looked at the display. “Where?”

Data enhanced the map.

“London, England.”

Picard’s eyes narrowed. “Can you be more specific?”

“One moment.”

The map tightened again, shifting from a planetary view to a street grid. The computer struggled to reconcile twenty-fourth-century cartographic overlays with twentieth-century urban data pulled from satellite broadcasts and primitive mapping networks.

Then a highlighted circle appeared over central London.

Data turned from ops.

“The signal appears to originate from an area in London near King’s Cross railway station.”

Riker looked incredulous. “A scan from a train station?”

“Near one,” Data corrected. “I cannot determine whether the source is inside the station, beneath it, or in an adjacent structure. The signal is intermittent and appears to be partially masked.”

Geordi frowned. “Masked by what?”

“I do not know,” Data replied. “The masking field does not conform to any recognizable form of energy deflection. It is also not technological in a way our sensors can easily classify.”

Troi rose slowly from her chair.

“There is unusual activity there,” she said.

Picard turned to her. “Counselor?”

Troi’s face remained composed, but her voice was careful. “It’s difficult to describe. The minds in that area feel… concentrated. Agitated. Not panicked. More like anticipation. A great many people moving with purpose.”

Riker glanced at the screen. “In a city like London, that could mean anything.”

“Yes,” Troi said. “But this feels separate from the rest of the city. There is a distinction. Almost like two crowds occupying the same space, but not entirely aware of one another.”

Data looked intrigued. “That is an imprecise but potentially useful observation, Counselor.”

Troi gave him a sidelong glance. “Thank you, Data.”

Picard paced slowly across the command area, considering the planet below, the date, the scan, and the impossible duplication of the solar system itself.

“Can we safely beam through the masking field?” he asked.

Data checked the readings. “A direct transport into the precise source area would be inadvisable. The field may distort the annular confinement beam.”

Geordi nodded. “I agree. We could set them down a few blocks away, outside the interference. Somewhere public enough not to draw attention, but private enough to avoid being seen.”

Worf’s expression tightened. “Captain, sending an away team to a populated pre-warp Earth is a violation of protocol.”

“Under ordinary circumstances, Mister Worf,” Picard said. “However, someone on that planet has scanned a Federation starship in orbit. That suggests either technology far beyond the era, or some other influence we do not yet understand.”

Riker looked at him. “And if it is Earth’s past?”

Picard met his eyes.

“Then we tread very carefully.”

Riker nodded.

Picard straightened.

“Number One, assemble an away team. You’ll take Data and Counselor Troi. Civilian clothing appropriate to London, September 1999. No visible technology. No communicators unless they can be fully concealed.”

Riker gave a small nod. “Aye, Captain.”

“Your orders are observation only. Identify the source of the scan, determine whether the local population is aware of it, and avoid contact wherever possible.”

Data rose from ops. “Captain, given the primitive surveillance systems present in London at this period, I recommend we modify our approach to avoid visual detection by security cameras.”

Geordi looked up. “I can rig subcutaneous communicators and low-output tricorder functions into period-appropriate objects. A mobile phone, maybe a handheld camera.”

Riker’s mouth quirked. “A camera in London in 1999 won’t look out of place.”

“Indeed,” Data said. “Tourism levels in that area are historically significant.”

Picard gave Geordi a brief nod. “Make it so.”

Worf stepped down from tactical. “Captain, I request permission to accompany the away team.”

Riker glanced at him. “Worf, no offense, but you might attract attention in twentieth-century London.”

Worf’s jaw set. “I am capable of remaining discreet.”

Data looked at him. “Klingon cranial ridges were not common among humans in 1999.”

Riker’s smile widened slightly. “That’s one way of putting it.”

Worf did not look amused.

Picard spared him the argument. “Your place is at tactical, Mister Worf. If whatever is down there can scan us, I want you monitoring every frequency and every movement from orbit.”

Worf inclined his head. “Aye, Captain.”

Troi moved toward the aft stations. “I’ll need a few minutes to adjust to the population density before transport. Six billion minds on Earth is one thing. London alone may be overwhelming if there is some kind of hidden activity there.”

Picard nodded. “Take the time you need, Counselor.”

Riker stepped toward the turbolift with Data beside him.

As the doors opened, he looked back toward Picard.

“Captain, any advice for visiting Earth in 1999?”

Picard considered that for half a second.

“Do not alter history, Number One.”

Riker smiled faintly.

“Simple enough.”

Picard’s expression remained grave.

“And find out who, or what, is capable of seeing us.”

Kings Cross Station

The alley was narrow, damp, and poorly lit.

For a moment, the air shimmered faintly between two brick walls behind a row of overflowing rubbish bins. Then three figures resolved out of the transporter beam.

Riker materialized first, dressed in a dark jacket, open-collared shirt, and trousers that Geordi had assured him were “close enough for 1999 London without making you look like you’re trying too hard.” Troi appeared beside him in a long coat over a simple blouse and skirt, her dark hair loose around her shoulders. Data stood just behind them, wearing a tan overcoat and carrying what appeared to be a small mobile phone in one hand.

The alley smelled of rain, exhaust, old stone, and something fried from a nearby shop.

Riker glanced up at the strip of gray sky overhead.

“Transport complete,” he said quietly. “No alarms. No screams. I’ll take that as a good start.”

Data lifted the phone and pressed one of the buttons. To any passerby, it would have looked like a man checking a message. In reality, the device contained a heavily shielded tricorder array, short-range sensor suite, and an encrypted link to the Enterprise.

“Our arrival does not appear to have been observed,” Data said. “The nearest visual surveillance device is positioned at the mouth of the alley. Its field of view does not include our location.”

Troi looked toward the street beyond. Cars passed in fits and starts, horns sounding in the distance. Pedestrians moved along the pavement under umbrellas and coats, wrapped in their own concerns.

“It feels like Earth,” she said softly.

Riker looked at her. “In a good way or a bad way?”

Troi took a breath, letting the surrounding press of minds settle against her senses.

“In a crowded way.” She gave him a small, wry smile. “But nothing alarming. Most of the people nearby are focused on ordinary things. Work. Trains. Weather. Children. Someone is very annoyed about a late bus.”

Riker smiled faintly. “Some things don’t change in four hundred years.”

“No,” Troi said, but her expression remained thoughtful. “Most of them are ignoring us completely. We are simply three more people in a large city.”

Data turned toward the street. “King’s Cross Station is approximately four hundred and eighty meters northeast of this location. I have downloaded a map from the local public information network.”

Riker lifted an eyebrow. “You know the way?”

“Yes, Commander.”

“Lead on.”

Data stepped out of the alley with the complete confidence of a man who had studied the entire street layout of London in under twelve seconds.

Riker and Troi followed.

The city moved around them in restless layers. Black cabs rolled past in the street. Red double-decker buses groaned to a stop and hissed open their doors. People hurried along with newspapers, briefcases, shopping bags, school trunks, and coffee cups. The buildings were old and soot-darkened in places, with newer signs and advertisements layered over them like history trying to keep pace with commerce.

Riker looked around with open curiosity, though he tried to keep it subtle.

“Hard to believe this is all out here,” he murmured. “A second Earth. A second London.”

Troi watched a woman shepherd two children across the pavement while balancing a bag on her shoulder.

“Or a very convincing reflection of one.”

Data glanced back. “At present, there is no measurable difference between those possibilities.”

“That’s helpful,” Riker said.

“I am aware the distinction is unsatisfying.”

They crossed a street with the flow of pedestrians and continued toward the station. As King’s Cross came into view, the crowd thickened. People moved in and out through the entrance, some dragging suitcases, others checking watches or talking into mobile phones. The noise rose around them: footsteps, announcements, rolling luggage, train brakes, distant laughter.

Troi slowed slightly as they entered the station.

Riker noticed immediately. “Deanna?”

She shook her head. “I’m all right. There are more people here, but still nothing that suggests panic or awareness of anything unusual. They’re going about their day.”

“Can you sense the source of the odd activity?”

“Not clearly.” Her eyes moved across the station concourse. “There are little pockets of emotion that feel… out of step. Excitement. Nervousness. Anticipation. Mostly from children. But that could mean anything at a station.”

Data lifted the disguised tricorder again, apparently checking the phone’s small screen.

“The signal we detected from orbit is intermittent but present,” he said. “It is coming from inside the station.”

Riker leaned closer, keeping his voice low. “Can you pinpoint it?”

“Within fifteen meters. This way.”

They moved through the crowd, passing ticket counters and signs, then along the path toward the platforms. Data’s attention remained fixed on his device, but he maneuvered through the station with smooth precision, never colliding with anyone, never drawing notice.

Riker, for his part, had to sidestep a man carrying two enormous bags and a paper cup of coffee.

“Your century was crowded,” he said under his breath.

“London was one of Earth’s major urban centers in this period,” Data replied. “Its population exceeded seven million.”

“I wasn’t asking for statistics, Data.”

“No, sir. However, they seemed relevant.”

Troi’s expression shifted as they neared a line of platforms.

“It’s stronger here,” she said.

Riker looked at her. “The signal?”

“No. The feeling. Anticipation. A great deal of it.”

Data stopped and looked toward two adjacent platform entrances.

“The signal is centered between platforms nine and ten.”

Riker followed his gaze.

At first, nothing seemed unusual.

Passengers hurried past them. Families argued over luggage. A station employee gave directions to a harried businessman. A boy cried because he had dropped something under a bench. A woman in a dark coat scolded two children who were trying to climb onto a trolley.

And near a brick pillar between the platforms stood a pleasantly plump, red-headed woman.

She wore ordinary-looking clothing, though not quite in the same style as everyone else around her. She stood with the calm confidence of someone who had done the same thing many times before. Every few moments she glanced toward the crowd, smiled warmly, and made a small, encouraging motion with one hand toward the barrier.

No one went to her.

Or rather, no one Riker could see went to her.

She continued waiting, patient and untroubled.

Data’s eyes moved from his device to the woman, then back again.

“The scanning signal is originating from within three meters of that pillar,” he said quietly.

Riker looked at the brick wall between the platforms. “From the wall?”

“Possibly from beyond it.”

Riker gave him a sideways look. “Beyond the wall.”

“That is what the readings suggest.”

Troi studied the woman. “She sees us.”

The red-haired woman’s gaze had settled directly on them. She smiled as if she had been waiting for exactly this moment.

Riker straightened his jacket.

“Let me do the talking.”

Troi’s lips curved faintly. “You usually do.”

They approached the woman.

Her smile broadened. She had kind eyes, a flushed face, and the brisk warmth of someone accustomed to managing confusion, children, luggage, and minor chaos all at once.

“There you are, dears,” she said brightly. “Cutting it a bit close, aren’t you?”

Riker paused just long enough to realize he had no idea what the correct answer was.

“Apparently so,” he said.

The woman looked from him to Troi, then to Data. Her eyes lingered on Data for half a second, but if she found anything odd about him, she did not show it.

“First time to Hogwarts, is it?”

Riker smiled politely.

He had never heard the word before.

“Yes,” he said, with the easy confidence of a man walking blindly into a situation and hoping no one noticed. “First time.”

Troi glanced at him.

Data’s expression did not change, though his eyes shifted minutely toward Riker.

The woman softened at once. “Oh, well then, no wonder you look a bit lost. Nothing to worry about. Happens every year. Just straight through the barrier between platforms nine and ten. Best to do it at a bit of a run if you’re nervous.”

Riker looked toward the brick pillar.

Then back at her.

“Through the barrier.”

“That’s right.”

Data lifted his phone slightly and pressed another control. “Commander,” he said quietly, “my scans indicate that the structure before us is composed of standard twentieth-century masonry. Brick, mortar, and internal reinforcement. I am detecting no doorway, aperture, holographic projection, or transporter effect.”

The woman looked at the phone, amused. “That won’t help much, dear.”

Riker was about to ask what, exactly, she meant by that.

Then a small child pushing a trolley came racing toward them.

The boy could not have been more than eleven. His hair was untidy, his face bright with excitement, and his trolley was stacked with a trunk, a cage, and a pile of things held together by what looked like hope and string. He waved at the red-haired woman as he passed.

“Morning, Mrs. Weasley!”

“Mind your speed, dear!” she called.

The boy did not slow down.

He ran straight at the brick barrier.

Riker’s hand twitched instinctively.

Troi drew in a sharp breath.

The child vanished through the wall.

No flash.

No shimmer.

No sound.

One moment he was there, running toward solid brick.

The next, he was gone.

Riker stared.

Data stared as well.

For a brief and profound moment, Lieutenant Commander Data had no comment.

Then he looked down at his phone, pressed two controls, and looked back at the wall.

“I have no explanation for what just occurred.”

Riker exhaled slowly. “That makes two of us.”

Troi’s eyes remained fixed on the barrier. “Three.”

Mrs. Weasley gave them a fond, slightly impatient look. “Go on, then. You don’t want to miss the train.”

Riker looked at Troi. Troi looked at Data. Data looked at the wall as though it had personally violated several laws of physics.

Riker adjusted his coat.

“Observation only,” he murmured.

“Understood,” Data said.

Troi took a breath. “Together?”

Riker nodded. “Together.”

They walked toward the barrier.

Riker forced himself not to slow down. He had charged Borg drones, Ferengi pirates, Cardassian soldiers, Romulan boarding parties, and one notably unpleasant alien energy field. It was still remarkably difficult to make himself walk into a brick wall in a public railway station.

The brick rushed closer.

Instinct screamed that impact was imminent.

Then the air changed.

The noise of King’s Cross dropped away behind them as though someone had closed a door.

They emerged onto another platform.

Riker stopped.

Troi stopped beside him.

Data stepped through last and immediately turned back to examine the barrier from the other side.

The platform was packed.

But it was not the platform they had left.

A great scarlet steam engine waited on the tracks, glossy and impossible, its brass fittings gleaming beneath hanging clouds of white vapor. A sign overhead read Platform 9¾. Children hurried everywhere, most of them carrying trunks, cages, bags, books, robes, and pets. Owls hooted from perches. Cats wove underfoot. Parents called last-minute reminders. Older students greeted one another with hugs, shouts, and laughter.

Many of the people wore robes.

Actual robes.

Some wore hats. Some carried long, polished sticks tucked into sleeves or pockets. Several trunks moved with no visible assistance. A cage floated past them at shoulder height, followed by a distracted man who was reading a newspaper and not holding it.

Riker looked around slowly.

“Data.”

“Yes, Commander?”

“I’m going to need you to tell me I’m seeing this.”

“You are seeing this.”

“That isn’t as reassuring as I hoped.”

Troi’s expression was a mix of astonishment and concentration. “These are the minds I felt. They were here, but not here.”

Data examined the device in his hand. “The masking field appears to separate this platform from the surrounding station. I am unable to determine how. The field does not prevent physical passage, visual perception once inside, or local sound transmission, yet it prevents observation by those on the other side.”

“Like a cloaking device,” Riker said.

“Not exactly. A cloaking device bends or absorbs specific forms of energy. This appears to alter awareness and access according to criteria I cannot identify.”

Before Riker could respond, a man in dark robes moved past them carrying a stack of parcels. He gave them a distracted glance.

“You lot had better find a seat if you want to get to Hogwarts today,” he said. “Train’ll be off soon.”

Riker turned toward him. “Thank you.”

The man nodded once and disappeared into the crowd.

Riker looked at the train.

Troi followed his gaze. “Will?”

“Our orders are to identify the source of the scan,” he said quietly. “Right now, everyone here seems to be heading to the same place connected to that word the woman used.”

“Hogwarts,” Data said.

Riker glanced at him. “Anything in the local databases?”

“Nothing credible. The term appears in folklore, children’s fiction, and scattered cultural references. None are consistent with a real institution.”

Troi looked at the train. “And yet there’s an express.”

Riker made his decision.

“We board. We observe. We do not interfere.”

Data looked back toward the barrier. “It may be possible to return the way we entered.”

“May be?”

“I am not yet certain.”

Riker sighed. “Put that on the list of things not to tell the captain until we know more.”

They made their way onto the train.

The inside was narrow, warm, and full of noise. Children passed them in the corridor, laughing, arguing, calling to friends in compartments. Some wore ordinary clothing, others robes, and a few seemed to be attempting to change from one to the other while walking.

A frog leaped past Riker’s shoe.

He looked down.

The frog looked up.

Then it hopped away.

Riker decided not to ask.

They found an empty compartment halfway down the train. Riker slid the door shut once they were inside. Troi took the seat by the window. Data sat opposite her, posture straight, phone in hand. Riker remained standing for a moment, looking out at the platform.

Steam drifted across the glass.

Children waved goodbye to parents. Mothers dabbed at eyes. Fathers lifted younger siblings onto shoulders. Owls rattled in their cages. A boy with bright red hair leaned out of a nearby window, calling something to a group of identical-looking older boys who were laughing far too hard at whatever they had done.

Riker finally sat.

“All right,” he said quietly. “Thoughts.”

Data looked down at his device. “We have encountered a concealed transportation platform within King’s Cross Station. Its occupants appear to possess access to technology or phenomena inconsistent with Earth’s known development in 1999. The concealment mechanism appears to have prevented detection by conventional Federation sensors until our upgraded arrays encountered its associated energy signature from orbit.”

Troi looked out the window. “They don’t feel like scientists hiding an experiment. They feel like students. Families. Teachers. A whole society.”

“Hidden in plain sight,” Riker said.

“That would explain the lack of surface infrastructure,” Data added. “If this society operates alongside the general human population while using methods undetectable to conventional instruments, our initial scan would have failed to classify them as a separate civilization.”

Riker leaned back. “So Earth, or whatever this Earth is, has two populations. One ordinary late-twentieth-century human civilization, and one hidden civilization with abilities we can’t explain.”

“An oversimplification, but accurate,” Data said.

Troi glanced at him. “And one of them scanned the Enterprise.”

“Or the scan originated from the field surrounding the platform itself,” Data said. “The signal may have been an automatic response to our orbital scans.”

Riker frowned. “Like a sensor tripping an alarm.”

“Possibly.”

The train whistle sounded, sharp and long.

A moment later, the carriage jerked.

The platform began to slide past.

Riker looked out the window as parents and children waved. The scarlet engine pulled away from Platform 9¾, and the hidden station slipped behind them into steam.

Within minutes, London gave way to rail lines, then streets, then the first hints of countryside.

Data continued scanning through the disguised phone.

“The train is accelerating,” he said.

Riker glanced at him. “It’s a steam train.”

“Yes.”

“How fast?”

“Already exceeding safe operating limits for a conventional steam locomotive of this apparent design.”

Troi looked out as the scenery blurred faster.

“By how much?”

Data tilted his head. “Substantially.”

Riker watched the countryside sweep past the window at a speed no twentieth-century train of this type should have managed.

“Of course it is.”

Data pressed another control. “There is no corresponding increase in boiler pressure sufficient to account for the acceleration. The locomotive is not operating by steam power alone.”

“Can you determine the secondary mechanism?”

“No.”

Riker gave him a look.

Data glanced up. “At this time.”

They rode on.

The train settled into a rhythm that was almost soothing despite everything impossible about it. Students passed in the corridor. A smiling woman with a trolley offered sweets Riker had never heard of. Data quietly purchased several with coins Geordi had included as part of their cover, then spent several minutes analyzing the packaging.

Riker refused something that appeared to be moving inside its wrapper.

Troi accepted a small packet of chocolate and ate it with the careful expression of someone grounding herself in the familiar.

The countryside rolled by, greener and wilder as they moved north.

Nearly halfway through the journey, the compartment door slid open.

A young woman stood there.

She was slender, with long pale blonde hair and wide, dreamy eyes that seemed focused on them and somewhere far beyond them at the same time. She appeared to be about eighteen, dressed in robes over Muggle clothing, with a necklace made from what looked like small corks. There was an airy stillness about her, not vacant, but unanchored from the usual hurry of the world.

“Hello,” she said.

Riker stood automatically. “Hello.”

“May I sit here? The compartment three doors down has a very loud argument about whether invisible ink should count as cheating, and I think one of them may be wrong in a dangerous way.”

Troi smiled gently. “Of course.”

The young woman stepped inside and sat across from them beside Data. She folded her hands in her lap and looked at each of them in turn.

“I’m Luna Lovegood.”

“William Riker,” he said. “This is Deanna Troi, and Data.”

Luna’s gaze settled on Data for a long moment.

“Data,” she repeated softly.

“That is correct,” Data said.

“What an honest name.”

Data blinked once. “Thank you.”

Riker sat again, watching her carefully. “Are you a student at Hogwarts?”

“Yes.” Luna tilted her head. “Though this is my last year. Probably. Unless something very interesting happens and time gets confused again.”

Troi’s eyes flicked toward Riker.

Riker kept his expression neutral. “Does that happen often?”

“Not as often as people think.” Luna looked out the window. “But more often than they admit.”

There was a silence.

Riker decided to shift course. “You seemed to recognize that we were new.”

Luna looked back at him. “Most people going to Hogwarts know where they are going before they get on the train.”

“That’s fair.”

“Also, none of you looked surprised enough at the chocolate frogs.”

Data looked down at the unopened package in his hand. “Should I have appeared more surprised?”

“Probably.”

“I will keep that in mind.”

Luna smiled faintly.

She looked at Troi. “Where are you from?”

“San Francisco,” Troi said smoothly.

Luna watched her for a moment.

“You spent time there,” she said.

Troi’s expression changed almost imperceptibly.

Luna’s voice remained soft and matter-of-fact. “But that isn’t where you’re from.”

Riker felt the temperature in the compartment shift, though nothing had actually changed.

Troi held Luna’s gaze. “I’ve lived in several places.”

“That must make answers difficult,” Luna said.

Riker leaned in slightly, redirecting her attention. “I’m from Alaska.”

Luna turned to him. “That’s very cold.”

“It can be.”

“Lots of open sky there.”

“Yes.”

“That’s nice. People need places where the sky is bigger than their problems.”

Riker was not sure how to respond to that.

Data spoke next. “I was born in San Francisco as well.”

Luna turned her head toward him.

Her pale eyes rested on his face.

“No,” she said.

Data paused.

Riker’s shoulders tightened slightly. “No?”

Luna did not look alarmed. She did not look accusatory. If anything, she looked gently curious.

“No,” she repeated. “You may have begun there, in some way. But you were not born there.”

Data’s expression remained composed. “That is an interesting distinction.”

“It usually is.”

Troi watched Luna with growing interest. “And where are you from?”

“Ottery St. Catchpole,” Luna said. “Down in Devon. I grew up near the Weasleys. You met Mrs. Weasley at the barrier, I expect. She’s very good at helping people through who don’t know where they’re meant to go.”

Riker smiled faintly. “She was helpful.”

“She usually is.”

Riker leaned back, adopting a casual tone. “We’ve been away for a while. I’m afraid we’re still catching up on recent events.”

Luna looked at him, dreamy and unreadable.

“There have been lots of those.”

“Yes, I gathered.”

“Some were terrible. Some were brave. Some were both.” She glanced toward the passing countryside. “People keep trying to decide which parts matter most, but they usually choose the loud parts.”

Riker waited.

Luna did not continue.

He tried again. “And Hogwarts? Is it safe?”

Luna looked back at him.

“Safer than it was. Less safe than people say. That’s usually true of schools.” Her expression brightened slightly. “You’ll be there in about an hour. If you’re new, you might want to go with the first years for Sorting.”

Riker nodded slowly. “Sorting.”

“Yes. It helps the castle decide where to put you.”

Data looked intrigued. “The castle decides?”

“Not exactly.” Luna considered this. “But it listens.”

Troi’s eyes narrowed slightly, not in suspicion, but concentration.

Luna stood.

“I should go. Neville said he’d save me a seat if the compartment didn’t fill with people who needed to be somewhere else.”

Riker rose as well. “Thank you, Luna.”

She smiled at him.

“You’re welcome. Try not to worry too much. It makes the Wrackspurts very busy.”

She slid the compartment door open, stepped into the corridor, and drifted away through the train as lightly as she had arrived.

Riker waited until she was gone.

Then he looked at Troi.

“What did you get from her?”

Troi remained silent for a moment, her gaze still on the closed door.

“Almost nothing.”

Riker frowned. “Nothing?”

“Most of the time she was blank to me. Not empty. Not shielded exactly. Just… difficult to read. Like trying to hear one voice through water.”

Data looked up from his device. “Could she possess telepathic defenses?”

“I don’t know,” Troi said. “I did sense something once or twice.”

“When?” Riker asked.

Troi turned toward him.

“When we lied.”

Riker’s expression sobered.

“She knew?”

“I’m not sure what she knew,” Troi said. “But she felt it. A little flicker of agitation. Not anger. Not fear. More like disappointment.”

Data’s gaze shifted toward the corridor.

“She also correctly identified that I was not born in San Francisco.”

Riker looked at him. “Didn’t Dr. Soon start your matrix there? You were built at the colony of Omicron Theta.”

“Yes. Her statement was technically accurate.”

Riker leaned back against the seat and looked out the window. The countryside raced past far faster than the train had any right to travel.

“A hidden platform. A train that breaks physics. A school we can’t find in any database. A young woman who can tell when we’re lying.”

Troi folded her hands in her lap. “And a society no one on Earth seems to know exists.”

Data’s phone chirped softly.

He looked down.

“The train has just passed through a region of localized spatial distortion.”

Riker closed his eyes briefly.

“Of course it has.”

Troi looked toward the window as distant hills rose beyond the glass.

“We are very far from King’s Cross now,” she said.

Riker opened his eyes and watched the unfamiliar countryside blur past.

“Then let’s hope Hogwarts has answers.”

Hogwarts Castle

The Hogwarts Express slowed beneath a sky bruised purple by evening.

Steam rolled past the windows in thick white clouds, pressing against the glass before tearing away into the dark. The steady rhythm of the wheels changed, metal shrieking softly as the train eased into the station.

Riker stood first, pulling his coat straight and looking through the compartment window.

Outside, students were already crowding the corridor, laughing, shouting, tugging trunks down from racks and trying to keep cages upright. Owls hooted irritably. Cats darted between ankles. Someone somewhere yelled that they had lost a toad.

Again.

Troi rose more slowly, one hand brushing the side of the compartment wall as if steadying herself. The press of emotion around them had grown stronger as the train neared its destination. Excitement, nerves, homesickness, old friendships being resumed, rivalries picking up exactly where they had left off.

Data stood beside the door and checked the disguised phone in his hand.

“The locomotive has reduced speed to a conventional rate,” he said. “However, the method by which it maintained its prior velocity remains undetermined.”

Riker gave him a faint look. “Add it to the list.”

“I have been maintaining a list, Commander. It is now quite extensive.”

“I was afraid of that.”

The compartment door slid open, and they stepped into the narrow corridor with the other students.

They were taller than most of the crowd around them, noticeably so. Riker tried to move with the same casual confidence he had used in a hundred unfamiliar diplomatic receptions, but it was difficult to ignore the fact that everyone around them was a child or young adult dressed in robes, carrying wands, cages, cauldrons, and trunks.

They exited the train into a small, dark station surrounded by trees and damp mountain air.

The smell struck Riker first.

Cold water. Wet stone. Pine. Smoke from the train. Lantern oil. Earth after rain.

He looked past the platform and saw darkness rolling out in every direction, broken by bobbing lanterns and the silhouettes of students clustering together in little knots.

Then a voice boomed across the station.

“Firs’ years! Firs’ years over here! Come on now, don’ be shy! Firs’ years this way!”

The voice belonged to the largest man Riker had ever seen outside of certain non-human worlds.

He stood at the edge of the platform, holding a lantern high above his head. He had wild dark hair, a great beard, and a coat that looked as if it had been made from several coats stitched together. He towered over the children around him.

Riker stared for half a second.

Data leaned closer and spoke in a low voice.

“Commander, that individual appears to be approximately two point seven four meters tall.”

Riker kept his voice equally low. “That’s about nine feet.”

“Correct. He also possesses a skeletal and muscular structure inconsistent with baseline human morphology.”

“Data.”

“Yes, Commander?”

“Not now.”

Troi looked toward the man, studying him with quiet curiosity. “He does not feel threatening.”

The large man spotted them almost immediately.

His lantern lifted a little higher.

“Oh,” he said, blinking through the steam. “There yeh are.”

Riker straightened slightly.

The man looked them over, then smiled in a way that seemed to take up most of his face.

“Transfer students, eh? Thought yeh might be comin’ along with this lot.” He waved one enormous hand toward the nervous first years gathering near him. “Best if you three take yer own boat. Let the little ones have the ride with their friends. First time’s important, that is.”

Riker hesitated only a fraction of a second.

“Of course.”

The man pointed down a sloping path toward the lake. “Bigger boat’s down there for yeh. Can’t miss it. Just climb in and keep yer hands inside. They know the way.”

Data’s head tilted. “The boats know the way?”

The large man chuckled. “They always do.”

He turned back toward the first years and raised his lantern again.

“Right then! Everyone follow me! Mind yer step. It’s a bit slippery, and I don’ want to fish anyone out before the feast.”

Riker motioned for Troi and Data to follow.

“This way.”

They moved with the crowd of first years down the dark path toward the lake. Children whispered around them, some casting glances at the three tall strangers but most too occupied with nerves and excitement to question their presence. The path curved between trees, and then the lake appeared ahead of them, black and still beneath the deepening night.

Small boats waited along the shore.

They were wooden, old-fashioned, and apparently unpowered.

A larger boat bobbed a little apart from the rest.

Riker looked at it.

“No oars,” he observed.

“No visible propulsion system,” Data added. “No sails, no engine housing, no magnetic rail, no energy emissions consistent with standard antigravity or gravimetric displacement.”

Troi stepped carefully into the boat. “And yet I suspect it will move.”

Riker followed her, then Data. The boat rocked under their combined weight, settled, and then remained perfectly balanced.

A few meters away, the large man stepped into a boat large enough to hold him comfortably, then turned toward the fleet of smaller boats filled with first years.

“Everyone in? Right! Forward!”

The boats began to move.

No one touched them.

No engine sounded.

No current pulled them.

They simply glided away from shore.

Riker sat very still, hands resting lightly on his knees.

“Data?”

Data had his disguised tricorder out, his thumb moving over the false keypad.

“I am detecting no mechanical propulsion. There is, however, a low-level field surrounding the boat.”

“What kind of field?”

“Unknown.”

Riker looked at Troi. “I’m starting to dislike that word.”

Troi’s gaze remained on the water. “It does seem to be coming up often.”

The lake was dark enough to reflect the sky, giving the impression that the boats were moving through stars. Lanterns bobbed ahead of them, carried by the children’s boats and by the great man at the front. The shoreline slipped away. Trees became black shapes against the horizon.

For a time there was only water, mist, and the low murmur of young voices.

Then the boats rounded a bend.

The castle appeared.

Riker forgot to breathe for a moment.

It rose from the cliffs above the lake, vast and ancient, a maze of towers, turrets, walls, windows, bridges, and impossible angles. Lanterns burned along its walls. Small flames glowed in high windows. Towers pierced the darkening sky like something from a storybook given stone and scale. The cliffs beneath it plunged down toward the lake, and the whole structure seemed less built than grown out of the mountain itself.

Troi looked up, her face softening.

“That is extraordinary,” she whispered.

Data studied it with his usual attentive calm, though his eyes moved rapidly, cataloging everything. “The architecture suggests multiple periods of construction. However, certain structural elements appear physically improbable.”

Riker laughed under his breath. “Physically improbable. That’s one way to put it.”

Troi’s expression changed again.

Riker noticed. “Deanna?”

She kept her eyes on the castle.

“I feel something from it.”

Data turned toward her. “From the structure?”

“Yes.” She sounded almost uncertain of herself. “That is an odd thing to say, I know. But there is an impression. Not like a person. Not even like a living creature exactly. More like…” She searched for the right words. “A welcome.”

Riker looked from her to the castle.

“You’re saying the castle feels happy to see us.”

Troi gave him a small, bewildered smile. “In a sense, yes.”

Data’s brows lifted slightly. “Fascinating.”

“There’s something else, too,” Troi added.

Riker looked back at her. “What?”

“Happiness. Curiosity. And just a little irritation.”

Riker followed her gaze to the castle’s many lit windows.

“Irritation from the castle?”

“I did say it was odd.”

The boats continued across the lake, gliding toward the cliffs. The castle grew larger with each passing moment, its reflection shivering across the water. Lanterns flickered along the path ahead. Somewhere above them, a bell sounded deep and slow.

The boats entered a covered boathouse beneath the cliff.

One by one, students climbed out. As each group left its boat, the vessel drifted away from the dock, turned neatly, and sank beneath the black water without a ripple of alarm from anyone present.

Riker watched the first one vanish.

Then the second.

Then the third.

He turned to Data.

Data looked down at his phone.

“The boats are submerging.”

“I can see that.”

“They are doing so without taking on water.”

“I can see that, too.”

“I cannot explain it.”

“Still?”

“Still.”

The large man waved the first years onward.

“Up the stairs now! Don’ dawdle! Professor’s waitin’!”

Riker, Troi, and Data followed the stream of children up a long stone stairway carved into the cliff. The climb was steep and damp, lit by torches that burned blue-white in the night air. The castle loomed above them, growing more solid and more impossible with each step.

At the top, they emerged into a courtyard paved in old stone. The air smelled of rain, ivy, candle smoke, and something warm from inside.

Waiting at the entrance stood an older woman in emerald robes.

She had a stern face, sharp eyes, and a bearing that reminded Riker immediately of several admirals he had known who could reduce a room to silence by clearing their throats.

The first years quieted almost at once.

The woman’s gaze swept over them, and then over Riker, Troi, and Data.

She did not look surprised.

That concerned Riker more than if she had.

“Welcome to Hogwarts,” she said, her voice crisp and carrying easily through the courtyard. “I am Professor Minerva McGonagall, Deputy Headmistress of Hogwarts School of Witchcraft and Wizardry.”

Data looked at Riker.

Riker gave a barely perceptible shake of his head.

Not now.

Professor McGonagall continued.

“In a few moments, you will pass through these doors and join your classmates. But before you take your seats in the Great Hall, you will be sorted into your houses. The four houses are Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. Your house will be something like your family while you are here. Your triumphs will earn your house points. Any rule-breaking will lose house points.”

Several children shifted nervously.

Riker noticed Data’s eyes tracking every reaction.

“At the end of the year,” McGonagall said, “the house with the most points is awarded the House Cup.”

Her eyes moved again, this time settling directly on the three of them.

“As for our taller transfer students,” she said, with only the faintest tightening of her mouth, “the Headmaster will wish to speak with you after the feast.”

Riker inclined his head politely.

“Of course, Professor.”

McGonagall studied him for half a beat longer than necessary, then turned.

“Follow me.”

The doors opened.

They entered the Great Hall.

Riker had been aboard starships, alien palaces, crystalline temples, Romulan Senate chambers, and Federation Council reception halls. He had seen cities beneath oceans and stations built into asteroids.

The Great Hall still made him pause.

Four long tables stretched the length of the chamber, packed with students in black robes. Hundreds of candles floated in the air above them, their flames steady despite the absence of any visible support. The ceiling did not appear to be a ceiling at all, but a living image of the night sky outside, clouds drifting across stars in impossible depth.

At the far end of the hall stood a raised staff table. Teachers watched from behind it, some curious, some amused, some openly suspicious.

No one at the student tables appeared older than eighteen or nineteen.

“An educational institution,” Data murmured. “The age distribution is consistent with secondary schooling.”

Riker kept his eyes forward. “Except for the castle that thinks.”

“Possibly thinks,” Data corrected.

Troi gave him a look. “It was irritated.”

“That does not necessarily indicate cognition.”

Before Troi could answer, Professor McGonagall stopped beside a stool placed at the front of the hall. On the stool sat an old, patched, pointed hat.

Riker stared at it.

The hat twitched.

Then it opened a tear-like brim and began to sing.

It sang about houses, courage, loyalty, wit, ambition, unity, danger, history, and choices. Riker listened with increasing disbelief while the students watched as though this was perfectly normal. Data appeared fascinated. Troi appeared deeply uncomfortable.

When the song ended, the hall applauded.

Riker leaned slightly toward Data.

“Did that hat just perform?”

“Yes, Commander.”

“Good. I wanted to make sure.”

Professor McGonagall unrolled a long scroll.

“When I call your name, you will sit on the stool and place the Sorting Hat on your head.”

A nervous boy went first.

“Abbott, Simon!”

The child stumbled forward, sat on the stool, and had the hat dropped over his eyes.

A moment later, the hat shouted, “HUFFLEPUFF!”

One of the tables erupted in cheers.

The boy hurried toward it, looking relieved.

Several more followed.

“Bell, Charlotte!”

“RAVENCLAW!”

“Branstone, Amelia!”

“GRYFFINDOR!”

“Carmichael, Thomas!”

“SLYTHERIN!”

Riker watched carefully, trying to understand the process. The hat appeared to pause for varying lengths of time. Some decisions were instantaneous. Others took nearly a minute. The children reacted with relief, pride, disappointment, or shock.

Then Professor McGonagall looked down at the scroll.

“Troi, Deanna.”

The hall went quiet in a different way.

Not silent. Not suspicious exactly.

Curious.

Troi glanced once at Riker.

He gave her a small nod.

She walked to the stool, composed despite the fact that every student in the room was watching her. She sat, and Professor McGonagall placed the hat on her head.

The brim slipped low over her dark hair.

Troi stiffened.

Not much.

But Riker saw it.

The hat was speaking to her.

Not aloud.

Troi’s hands tightened faintly in her lap. Her eyes were hidden beneath the brim, but her posture changed with the unmistakable tension of someone who had just felt another mind touch hers without permission.

After several long seconds, the hat shouted, “RAVENCLAW!”

The Ravenclaw table applauded. Troi rose carefully and walked toward it, her face serene again, though Riker knew her well enough to see the disturbance beneath.

More names followed.

Data observed all of it with intense interest.

Then McGonagall called, “Soong, Data.”

A murmur passed through the hall at the unusual name.

Data walked to the stool with perfect composure and sat down.

Professor McGonagall placed the hat on his head.

The hat settled.

Nothing happened.

Several seconds passed.

Then several more.

The hall grew increasingly quiet.

Data looked straight ahead, expression unchanged.

Riker wondered what a magical mind-reading hat would make of an android positronic brain.

Apparently, the hat wondered the same thing.

At last, the hat shifted slightly.

Data’s eyes moved upward, as if trying to look at it.

“That is an inaccurate assumption,” he said aloud.

A wave of whispers moved through the students.

The hat muttered something no one else could hear.

Data replied, still calm, “I do possess curiosity. However, I do not possess ambition in the emotional sense you appear to imply.”

The students began whispering louder.

Professor McGonagall’s mouth tightened.

Data tilted his head. “Yes. I would agree that the pursuit of knowledge is one of my defining behavioral patterns.”

The hat shouted, “RAVENCLAW!”

The Ravenclaw table burst into applause, louder this time, partly amused and partly delighted. Data stood, removed the hat, handed it back to McGonagall, and walked to sit near Troi.

Riker caught Troi’s eye across the hall.

She looked unsettled.

Data looked intrigued.

That left Riker.

More students were sorted. The line shrank. The hall warmed with candlelight and whispered speculation. Riker remained standing near the end, feeling more exposed with every passing minute.

Finally, Professor McGonagall looked at the last name on the scroll.

“Riker, William.”

Riker walked forward.

The stool seemed smaller when he was the one sitting on it.

Professor McGonagall placed the hat on his head.

The world narrowed.

A voice spoke directly into his mind.

Not words through ears.

Thoughts.

Well now. What have we here?

Riker went very still.

The hat rustled faintly.

Not a child. Not quite a student. Courage, certainly. Loyalty, yes. Command instincts. A taste for risk. Protective. Restless. Hmm. You would have done well in Gryffindor. Very well.

Riker kept his face still.

But not only Gryffindor. There is a mind here that thinks in angles. Tactical. Curious when it suits you. Ambitious, too, though you dress it as duty.

Riker thought, very carefully, Who are you?

The hat seemed amused.

I could ask you the same.

Riker felt the pressure of the contact, old and strange and intimate. It was not like Betazoid telepathy. It was rougher, more direct, but not malicious. It rifled at the edges of him, tasting impressions rather than dragging out secrets.

You are very far from where you should be, William Riker.

His jaw tightened.

The hat’s voice softened.

But you are not here to harm them.

“No,” Riker whispered.

Professor McGonagall’s eyes narrowed.

The hat shouted, “GRYFFINDOR!”

The Gryffindor table erupted.

Riker removed the hat with relief he did not show and walked toward the cheering table. He sat among students who thumped the wood and welcomed him with grins before immediately turning back to their friends.

Across the hall, Troi and Data sat at Ravenclaw. Data had already begun speaking quietly to a student beside him, who appeared to be explaining something with great enthusiasm and several hand gestures.

Professor McGonagall rolled up the scroll.

Instead of returning to her seat, she turned toward the staff table and raised her voice.

“Students, faculty, and honored guests, welcome to the beginning of another year at Hogwarts. Please welcome the Headmaster of Hogwarts School of Witchcraft and Wizardry, Harry James Potter.”

The hall erupted.

Cheers, applause, whistles, and the pounding of hands on tables rolled through the chamber.

At the center of the staff table, a puff of smoke appeared.

When it cleared, a young man stood there.

Riker stared.

He looked barely older than the eldest students.

Perhaps eighteen. Perhaps nineteen.

He had untidy black hair, bright green eyes behind round spectacles, and a face that was still more boyish than adult. There was a lightning-shaped scar on his forehead. He wore deep red robes under an open black outer robe, and though he smiled, there was a weight behind his eyes that did not belong to anyone as young as he appeared.

The applause grew louder.

The young man lifted both hands.

“Please, please,” he said, his voice carrying through the hall without visible amplification. “Before someone starts stomping hard enough to wake the Founders, let’s all calm down.”

The students laughed.

The noise faded, though slowly.

Harry Potter smiled out over the hall.

“Welcome back to Hogwarts. And to our first years, welcome home. Speeches are dreadful when everyone is hungry, and I have no desire to be remembered as the Headmaster who stood between students and dinner.”

A wave of laughter moved through the room.

“So,” Harry said, “please enjoy.”

He clapped his hands once.

Food appeared.

Not replicated.

Not transported.

Not carried.

It simply appeared, filling every table at once in platters, bowls, pitchers, baskets, and steaming dishes.

Riker’s hand froze halfway to the goblet in front of him.

Across the hall, he saw Troi blink.

Data immediately looked down at the table with undisguised interest.

The students began eating as if nothing unusual had happened.

Harry Potter sat at the center of the staff table and began serving himself from a platter, speaking casually with Professor McGonagall beside him.

Riker slowly lifted the disguised phone Geordi had given him, angling it under the edge of the table as if checking a message.

The scan completed silently.

Across the room, Data’s head turned.

Riker glanced down at the small display.

The food contained nutritional value. Proteins, carbohydrates, fats, minerals, sugars, water. Organic structure consistent with standard cooked food.

Normal.

Except for how it had arrived.

Riker picked up his fork.

A Gryffindor boy beside him grinned. “You all right?”

Riker smiled back. “Just surprised.”

“First feast’ll do that.”

“I’m beginning to see why.”

Riker took a cautious bite.

The food tasted excellent.

That, somehow, was even more unsettling.

At the Ravenclaw table, Troi took a sip from her goblet, then exchanged a look with Data. Data had placed several different foods on his plate and appeared to be scanning them discreetly in sequence.

Riker tried to speak with the students around him.

“So,” he said casually to the boy beside him, “what classes are you looking forward to?”

“Defense,” the boy said immediately. “Everyone wants Defense now that Headmaster Potter’s teaching again.”

A girl across from him leaned in. “He isn’t teaching all of it. Professor Robards has the lower years.”

“Yeah, but Potter’s doing advanced practical sessions,” another student said. “My brother said last year he showed them shield work that could stop three simultaneous stunning spells.”

“Five,” someone corrected. “It was five.”

“Only because Samantha Burke panicked and fired early.”

Riker tried to guide the conversation. “And what sort of things has the Headmaster taught before?”

The students looked at him for a second, as though the question was faintly odd.

Then they went right back to arguing.

“Defense, obviously.”

“And dueling.”

“And curse-breaking theory for NEWT students.”

“He helped rebuild the wards after the war.”

“My cousin says he knows old magic no one else can do.”

“That’s rubbish.”

“It is not.”

Riker tried again. “What war?”

The students did not ignore him exactly. It was stranger than that. The conversation bent around the question as if it had fallen into a gap none of them noticed.

“Do you think he’ll teach Patronuses this year?” one boy asked.

“Only if the class is ready.”

“My sister says you need a really strong memory.”

“I’ve got one.”

“Winning a chocolate frog eating contest doesn’t count.”

Riker sat back slowly.

Across the hall, he could see Troi attempting something similar with two Ravenclaw girls. They answered ordinary questions easily, but any question about recent history, the hidden society, or Harry Potter himself seemed to slide away into chatter about classes, books, and school rumors.

Data’s face remained calm, but his eyes met Riker’s for a moment.

He had noticed.

The feast continued.

Time became difficult to judge.

Riker glanced once at his disguised phone and found that its internal chronometer had skipped, corrected, and then resumed. A few minutes seemed to pass. Then perhaps an hour. The candles overhead burned steadily. The enchanted ceiling deepened from evening to full night. Laughter filled the hall. Plates emptied and refilled. Students talked over one another. The staff ate, watched, smiled, and occasionally intervened when something at a table sparked, floated, or tried to crawl away.

Then, all at once, the food was gone.

The plates shone clean.

The conversation gradually quieted as Harry Potter stood again.

The hall settled faster this time.

Harry rested his hands lightly on the lectern before him.

“Right,” he said. “Start-of-term announcements. First, the Forbidden Forest remains forbidden. This may seem obvious given the name, but experience suggests it bears repeating.”

A ripple of laughter moved through the students.

Harry’s expression turned drier.

“For any student who believes the word forbidden is a personal challenge, please understand that the forest contains things that will not care how clever, brave, well-connected, or attractive you think you are.”

More laughter.

“I would prefer not to spend my evenings explaining to parents why their children were eaten, cursed, webbed to a tree, adopted by centaurs against their will, or otherwise subjected to an extremely uncomfortable death.”

The laughter became louder.

Professor McGonagall looked as though she was trying very hard not to smile.

Harry continued. “Second, Filch has asked me to remind everyone that dungbombs, self-inking shoes, portable swamps, and singing stair charms are banned in the corridors. I have asked him to provide a list of things that are not banned, as it would save parchment.”

Several older students cheered.

Filch, standing near a side door, looked murderous.

“Third, extracurricular clubs will begin meeting next week. Dueling Club will resume Friday evenings, supervised. And I do mean supervised. Anyone attempting to recreate last year’s incident with the animated armor will be cleaning the trophy room by hand.”

Someone at the Hufflepuff table groaned.

Harry’s eyes flicked toward them. “Yes, Mister Wallace. By hand.”

The hall laughed again.

He let the sound settle.

“Finally,” he said, and his tone softened, “to those of you returning, I am glad to see you home. To those of you here for the first time, this castle can be confusing, stubborn, drafty, occasionally rude, and very fond of stairs that think they’re funnier than they are.”

A few students glanced upward, as if the castle itself might object.

Harry smiled.

“But it is also safe. It is yours. Treat it kindly. Treat one another kindly. Learn as much as you can. Ask better questions than you think you’re allowed to ask. And when in doubt, do not poke anything glowing unless a professor tells you to.”

Data’s head tilted slightly across the room.

Riker could almost hear him filing that away.

Harry lifted his hands. “Prefects, please lead your houses to their common rooms. First years, try not to panic. Everyone gets lost at least once.”

The students began to rise.

Benches scraped. Voices swelled. Owls hooted from somewhere near the entrance. The four long tables broke into streams of black robes moving toward the great doors.

Then Harry Potter’s voice carried through the hall again.

Not loudly.

Not with command.

Quietly.

“You three should remain behind.”

Riker froze.

Across the hall, Troi and Data did the same.

No one else reacted.

The students continued leaving, laughing and talking, as if they had not heard him at all.

Riker looked toward the staff table.

Harry Potter was watching them.

Not the three tables.

Not the room.

Them.

His expression was unreadable.

Riker stood slowly. Troi and Data rose from Ravenclaw and crossed the hall to join him. Professor McGonagall remained near the staff table, hands folded, her stern expression giving away very little.

The last students exited.

The great doors closed.

Silence settled over the hall.

It felt much larger without the children in it.

The candles still floated overhead. The enchanted ceiling showed the night sky. The four long tables stood empty and spotless, as if hundreds of people had not just eaten there.

Harry Potter sat back down at the center of the staff table.

For several moments, he simply looked at them.

Riker resisted the urge to speak first.

Troi stood beside him, her face calm but her mind clearly working. Data remained still, the disguised phone hidden in his hand.

Harry’s gaze moved from Riker to Troi to Data.

His eyes lingered on Data.

Then he sat forward slightly.

“You came a long way to get here,” he said.

Riker chose his words carefully. “We were investigating an unusual signal.”

Harry nodded once, as though that answer confirmed something.

“I expect you were.”

Professor McGonagall’s eyes sharpened, but she said nothing.

Harry stood.

The motion was casual, but the hall seemed to notice it. The candles flickered once. Somewhere in the stone, something old creaked softly.

“Come with me.”

Riker glanced at Troi.

She gave the smallest nod.

They followed.

Harry descended from the staff platform and walked toward a side door rather than the main entrance. McGonagall moved with them for several steps, then stopped.

“Headmaster,” she said.

Harry paused and looked back at her.

She did not ask a question. Not aloud.

Harry smiled faintly. “I’ll be careful.”

McGonagall’s lips thinned. “See that you are.”

Harry continued.

The door opened before he touched it.

Riker noticed.

So did Data.

They passed through a corridor lit by torches. Portraits lined the walls, their painted occupants pretending not to stare and failing badly. One elderly wizard in a purple hat leaned into his frame to get a better look at Data. Another whispered something to the portrait beside her and received a sharp elbow in response.

Data slowed a fraction.

Riker murmured, “Keep walking.”

“I am attempting to identify the mechanism by which the paintings move and respond.”

“Do it while walking.”

“Yes, Commander.”

Harry led them through another door, down a short passage, and out into the night.

They emerged into a courtyard open to the sky.

The air was cool and clean. Stone walls rose around them, silvered by moonlight. Beyond the arches, the dark grounds rolled away toward the lake, the forest, and the distant mountains. Lanterns burned along the walls, their flames steady in the breeze.

Harry walked to the center of the courtyard and stopped.

For a moment, he said nothing.

Riker, Troi, and Data stood a few paces behind him, surrounded by ancient stone and impossible quiet.

Harry looked up at the stars.

Then, slowly, he turned back to face them.

Hogwarts Courtyard

The courtyard was quiet.

Not empty, exactly. The castle was never empty. Even now, with the students gone from the Great Hall and the evening settled over the grounds, there were small sounds everywhere: the whisper of wind over stone, the distant creak of old doors, the murmur of portraits somewhere behind the walls, the soft movement of trees beyond the courtyard arches.

Harry Potter stood beneath the open sky, his robes stirring faintly around him.

For a moment, he looked exactly like what he appeared to be.

Young.

Barely more than a teenager.

A headmaster too young for the title, standing in a castle far older than anyone alive should have been.

Riker watched him carefully, measuring posture, distance, exits, angles. Data stood slightly to his left, still and attentive. Troi stood on Riker’s other side, her eyes fixed on Harry with growing uncertainty.

Then Troi felt it.

The change did not happen visibly.

Harry’s face did not alter. His hair remained untidy. His eyes remained bright green behind round spectacles. The lightning-shaped scar still marked his forehead. The body before them remained young, slim, and human.

But something else shifted.

Something that had been held close, folded away behind a practiced human expression, loosened.

Troi inhaled sharply.

Riker glanced at her. “Deanna?”

She did not answer at once.

Her gaze stayed on Harry.

The warmth she had felt from the castle, the odd welcome, the thousands of nearby minds, the emotional current of a school full of children and teachers and old memories—all of that still pressed faintly around her.

But Harry was no longer what he had seemed.

The mask, if that was what it was, had not vanished from his face.

It had vanished from her senses.

And beneath it—

Troi took a small step back before she could stop herself.

Riker’s expression hardened instantly. “What is it?”

Harry looked at her with something almost like sympathy.

Troi swallowed.

“He’s ancient,” she said softly.

Data turned his head toward her. “In what sense, Counselor?”

“I don’t know.” Her voice had gone quiet, almost reverent despite herself. “Not old like a Vulcan elder. Not old like someone who has lived one lifetime very well.” Her eyes remained locked on Harry. “Ancient beyond comprehension.”

Riker looked back at Harry.

The young man smiled faintly, but there was no humor in it.

“Close enough.”

The courtyard seemed to grow colder.

Harry folded his hands behind his back.

“So,” he said. “Why are you here?”

Riker took half a second to decide on an answer.

“We were told the Headmaster wished to speak with the transfer students.”

Harry blinked at him.

Then, slowly, he smiled.

It was not cruel.

It was worse than that.

It was tired.

“William Riker,” Harry said, “you are far too old to be a student here.”

Riker went still.

Harry’s gaze shifted.

“Deanna Troi is from Betazed, not San Francisco, no matter how much time she spent there.”

Troi’s breath caught.

Then Harry looked at Data.

“And the stiff-looking dude is an android with a positronic brain.”

Data’s eyebrows lifted.

Harry looked back at Riker.

“So you can cut the crap.”

For several seconds, no one spoke.

Riker’s practiced expression did not falter, but something behind his eyes changed. The easy bluff fell away. What remained was Starfleet officer, first officer, commander of an away team in unknown territory.

“All right,” Riker said.

Harry waited.

Riker took one careful step forward. “We’re from the Federation starship Enterprise. We’re currently in orbit of this planet.”

“I know.”

Data’s eyes narrowed slightly. “You were aware of our presence before we reached the surface?”

Harry looked up at the stars.

“Yes.”

He held out one hand.

A shimmer appeared above his palm.

Not a viewscreen. Not a hologram, at least not one Data could immediately classify. It was a small, perfect image suspended in the air: the Enterprise-D, graceful and unmistakable, hanging in orbit above the blue-white curve of Earth.

Riker stared at it.

Troi’s eyes flicked from the image to Harry.

Data lifted the disguised phone and scanned without moving his arm too obviously.

Harry glanced at him.

“You can put that away.”

Data paused.

Harry’s mouth quirked. “Or don’t. It won’t help much either way.”

Riker recovered first.

“We were investigating the system,” he said. “It didn’t appear on any Federation stellar cartography maps. When we entered, we discovered what appears to be a perfect duplicate of the Sol system. Same star. Same planets. Same orbital structure. Same Earth.”

Harry looked down from the image in his palm.

“And that bothered you.”

“It raised questions.”

Harry gave a short laugh.

“Questions,” he said, as if the word itself were both fond and painful. “Humanity never does get over those.”

The image of the Enterprise vanished.

Riker studied him. “Why does this system look like Sol?”

Harry did not answer immediately.

Instead, he looked past them toward the castle walls. His expression softened, just for a second, as though he were listening to something only he could hear.

Then he said, very clearly, “End Hogwarts Simulation One.”

Troi turned sharply.

The world stopped.

Not froze.

Stopped.

The sound left first.

No wind over stone. No distant creak. No murmur from the castle. No birds. No insects. No soft emotional weight of sleeping students, watchful teachers, anxious first years, hidden ghosts, old portraits, or the warm, strange welcome of the castle.

Everything vanished from Troi’s senses.

Everything except Riker.

And the familiar, almost-not-there presence of Data beside him.

Troi staggered slightly.

Riker caught her arm. “Deanna?”

“They’re gone,” she whispered.

“Who?”

“All of them.”

The courtyard around them remained for another breath.

Then the sky changed.

The stars dissolved.

Night peeled away like painted glass.

Sunlight flooded the courtyard.

The damp evening air became crisp and bright. The moonlit stone warmed beneath a clear blue sky. Beyond the arches, the dark grounds transformed into rolling green highlands under daylight. The lake glittered in the distance. The Forbidden Forest became a dense, shadowed mass of trees under morning sun.

There was no sound except their breathing.

No students.

No train.

No feast.

No hundreds of minds.

Just the castle.

The courtyard.

The highlands.

And Harry Potter.

Data’s fingers moved quickly over his device.

“Commander,” he said, his voice even but quieter than usual, “I can no longer detect lifesigns from anywhere in the immediate vicinity.”

Riker looked at him sharply. “None?”

“Correct. Prior to Mister Potter’s statement, my scans indicated several thousand lifesigns within the castle and surrounding grounds. I now detect only two organic lifesigns.”

Troi glanced at Data.

Data added, “Commander Riker and Counselor Troi.”

Riker looked back at Harry.

“What was that?”

Harry tucked his hands into his robe pockets.

“A very complicated set of isomorphic projections.”

Data turned fully toward him.

“Isomorphic projections of individual people?”

“Yes.”

“That level of simulation would require extraordinary computational resources.”

Harry’s mouth twitched. “You have no idea.”

Troi stared toward the castle entrance where students had just been pouring through the doors.

“They felt real.”

Harry’s expression changed.

It was subtle, but it cut through the air more deeply than anger would have.

Sadness.

Old, worn, familiar sadness.

Troi felt it now that he was no longer hiding himself.

It was vast.

“Yes,” Harry said quietly. “They usually do.”

Troi stepped forward. “Were they?”

Harry looked at her.

The youthful face remained, but his eyes belonged to something that had watched too many centuries die.

“Not for more years than I can count.”

Riker’s voice lowered. “They were based on real people.”

Harry did not answer.

He did not need to.

Data looked toward the empty hall doors. “The students, the professors, the passengers on the train, the woman at King’s Cross—”

“All of them,” Harry said.

Troi’s face softened despite the unease coiled beneath her ribs.

“Luna.”

Harry’s eyes flicked to her.

Riker remembered the pale blonde young woman in the compartment. Her dreamy voice. Her too-accurate observations. Her strange calm. Her disappointment when they lied.

“She knew,” Riker said.

Harry gave a small, reluctant chuckle.

“Luna usually does.”

Data tilted his head. “You are referring to the Luna Lovegood projection?”

“The Luna program,” Harry said, “has always been glitchy.”

Riker blinked. “Glitchy?”

“Yes.” Harry’s smile warmed with something that looked painfully close to affection. “No matter how many times I corrected the parameters, no matter how many times I rebuilt that part of the simulation, she kept noticing things she wasn’t supposed to notice. Lies. Gaps. Edges. Places where the world didn’t quite fit.”

Troi listened, still feeling the echo of that strange blankness from the girl on the train.

“You never changed it?”

Harry looked toward the lake.

“No.”

“Why?”

Harry was silent for a moment.

Then he said, “Because some odd part of me always thought a little of her spirit lived on in it.”

The courtyard settled into stillness again.

Riker looked from Harry to the castle, then back again.

“What is this place?”

Harry’s expression closed.

“You’re not ready.”

Riker frowned. “Not ready for what?”

Harry looked at him with sudden sharpness.

“For the answers you’re asking for.”

“We came here because someone on this planet scanned our ship.”

“Yes.”

“And because this system is an exact copy of Sol.”

“Yes.”

“And because you appear to be the only person in a simulated version of Earth’s past.”

Harry’s eyes hardened slightly.

“Careful, Commander.”

Riker held his ground. “We have a responsibility to understand any potential threat to the Federation.”

Harry gave him a flat look.

“The Federation is not threatened.”

“Then what is this system?”

Harry’s jaw tightened.

“A tomb. A memory. A warning. A mistake. Pick one. They’re all true depending on the day.”

Data took half a step forward. “If this is a constructed system, its creators possessed power on a scale that would be of significant concern to Starfleet.”

Harry turned on him.

For the first time, irritation broke through the mask completely.

“Of course it would,” he said. “That’s what people like you do. You find something you don’t understand, classify it, scan it, name it, brief it, debate it, and then convince yourselves you’ve done something wise.”

Riker’s expression sharpened. “We are explorers.”

Harry laughed once.

It was not kind.

“So were we.”

Troi felt the bitterness behind the words and the grief under it.

Riker softened his tone without backing down. “Then help us understand.”

Harry looked at him for a long moment.

Then shook his head.

“No.”

“Harry—”

“No.”

The word moved through the courtyard like a door closing.

Even Data went still.

Harry exhaled, as if forcing himself back from the edge of something far older and far more dangerous than the young face he wore.

“You should go back to your ship,” he said.

Riker looked up at the sky, where the Enterprise was somewhere far above them, invisible in daylight.

“Our transporters may have difficulty locking onto us.”

“They won’t.”

Data looked down at his device. “I am not currently detecting a transporter lock.”

Harry gave him a tired look. “I didn’t say you’d use yours.”

Riker did not like the sound of that.

“Wait,” he said. “There are still questions—”

Harry flicked his hand.

Three small objects spun through the air.

Coins.

Round, dull, and old-looking, marked with symbols Riker did not recognize.

One struck Riker in the chest.

Another hit Troi’s shoulder.

The third tapped Data neatly against the front of his coat.

Riker had just enough time to look down.

Then space folded.

There was no transporter shimmer.

No familiar pull of dematerialization.

No momentary suspension.

One instant, he stood in a sunlit courtyard in the Scottish Highlands.

The next, he was on the bridge of the Enterprise.

He stumbled half a step.

Troi appeared beside him, one hand going instinctively to the railing near the command well.

Data arrived a fraction later, perfectly upright, though his eyes moved rapidly as he processed the transition.

The bridge went silent.

Every officer turned.

Worf’s hand went immediately to tactical.

Geordi, standing near the engineering station, stared openly.

Captain Picard stood from the command chair.

His eyes moved over Riker, Troi, and Data in quick assessment.

“Number One?”

Riker looked at him, still catching up to the fact that there was carpet beneath his boots instead of ancient stone.

“Captain.”

Picard’s expression remained controlled, but his eyes were sharp.

“Report.”

Riker glanced at Troi.

She looked pale.

Data looked down at the coin still resting against his coat.

Then the coin vanished into a wisp of gold dust.

The same thing happened to the one at Troi’s shoulder.

Riker’s coin dissolved against his jacket.

Picard saw all of it.

His face did not change.

“Briefing room,” he said. “Now.”

Riker nodded. “Aye, sir.”

Picard turned toward Worf. “Maintain current orbit. Full sensor sweep of the planet and surrounding space. Do not initiate active scans of the surface without my authorization.”

“Aye, Captain.”

“Mister La Forge, join us in five minutes. Doctor Crusher as well.”

Geordi nodded, still looking at the away team. “Yes, sir.”

Picard looked back at Riker.

“You can begin by telling me how you returned to my bridge without use of the transporter.”

Riker rubbed a hand over his face.

“That may take a while.”

Picard’s brow lifted slightly. “I gathered as much.”

Riker started toward the briefing room, then stopped.

“Captain, I’m sorry we were out of communication for the last several hours.”

Picard looked at him strangely.

“Several hours?”

Riker turned back.

Troi looked up sharply.

Data checked the bridge chronometer.

Picard’s voice was precise.

“Number One, you have been gone for thirty-two minutes.”

Riker stared at him.

Behind him, Troi’s face went still.

Data’s head tilted.

“That,” Data said quietly, “is troubling.”

Briefing Room

The briefing room doors closed behind them with a soft hiss.

For several seconds, no one sat.

Riker stood near the far end of the table, his jacket still faintly damp from the misty Highland air that, according to the Enterprise computer, he had never spent more than half an hour breathing. Troi stood beside him with one hand resting lightly on the back of a chair. Data remained upright and composed, though his gaze had fixed on nothing in particular in the way it sometimes did when he was processing an unusually large number of contradictions.

Picard took his place at the head of the table.

He did not sit either.

“Begin at the transporter,” he said.

Riker drew in a slow breath. “We materialized in an alley a few blocks from King’s Cross Station. The surface appeared consistent with London, Earth, September 1, 1999. No signs we’d been detected. Data led us to the station. We tracked the scanning signal to the area between platforms nine and ten.”

Picard’s eyes narrowed slightly. “And that is where you lost communications?”

“We didn’t realize it at first,” Riker admitted. “Everything seemed normal until we found the source. There was a woman standing by a pillar, directing people through a wall.”

Picard’s brow lifted.

“Through a wall?”

“A solid brick wall,” Data said. “My scans at the time indicated standard twentieth-century masonry. No visible aperture. No transporter field. No holographic displacement. A child then passed through it with a luggage cart.”

Picard looked at him for a long moment. “A child passed through a solid wall.”

“That is correct, sir.”

“And you followed.”

Riker gave a faint, rueful smile. “It seemed to be where everyone else was going.”

Picard finally sat down, though his expression did not soften. “Continue.”

Troi took over. “On the other side was a hidden train platform. It was crowded with children, families, and what appeared to be a concealed society operating alongside the visible human population. I could sense them. Hundreds of distinct emotional impressions at the station. Later, thousands at the castle.”

“The castle,” Picard repeated.

“Hogwarts School of Witchcraft and Wizardry,” Data said.

Picard looked at him.

Data continued, “The institution appeared to function as a boarding school for children and adolescents. Its inhabitants referred to themselves as witches and wizards. The phenomena we observed included physical concealment fields, mind-affecting barriers, self-propelled boats, a locomotive exceeding the mechanical limits of a steam engine, animated paintings, floating candles, instantaneous food manifestation, and a sentient hat capable of telepathic assessment.”

Picard sat very still.

Riker pulled out a chair and sat down. “That about covers it.”

Troi sat beside him. “Not quite.”

Picard turned to her. “Counselor?”

“The headmaster,” Troi said quietly. “Harry Potter. He appeared young. Eighteen, perhaps. Nineteen. But when we were alone in the courtyard, something changed. Not visibly. Empathically.”

She paused, searching for words that did not seem large enough.

“It was as if he stopped pretending.”

Picard’s eyes remained fixed on her.

“What did you sense?”

Troi looked toward the window, where the impossible planet turned beneath them.

“Age. Grief. Power. Loneliness.” She swallowed. “And something I cannot describe. He was ancient. Not simply old. Ancient beyond comprehension.”

Riker leaned forward. “He knew who we were. Full names. Where we were really from. He knew Data was an android. He knew about the Enterprise. He showed us an image of the ship in orbit, projected in the palm of his hand.”

Picard’s voice was quiet. “Did he threaten you?”

“No,” Riker said. “Not directly.”

“That is not reassuring, Number One.”

“No, sir.”

Data placed the disguised phone on the table. “He then terminated what he called ‘Hogwarts Simulation One.’ The surrounding environment altered from night to day. The lifesigns I had previously detected vanished. Thousands of individuals ceased to register on sensors. Only Commander Riker and Counselor Troi remained as organic lifesigns in the area.”

Picard turned slowly toward Data. “The students, teachers, passengers, everyone you encountered—gone?”

“Yes, sir. Mister Potter described them as very complicated isomorphic projections of individuals.”

Troi’s voice softened. “He said they had not been real for more years than he could count.”

The doors opened.

Doctor Crusher entered first, carrying a medical tricorder, with Geordi La Forge half a step behind her holding an engineering kit and a padd.

Crusher looked immediately to Riker, Troi, and Data. “I heard we had an away team return without using the transporter.”

“That is correct, Doctor,” Picard said. “Begin with Commander Riker and Counselor Troi. Full scans.”

Geordi moved around to Data’s side of the table. “Data, I want to check your internal chronometer and memory buffer if you don’t mind.”

“Of course.”

Crusher opened her tricorder and began with Troi.

“Any dizziness? Nausea? Disorientation?”

Troi gave a faint smile. “Given the circumstances, all three seem possible.”

Crusher glanced up. “Deanna.”

“No. Physically, I feel all right.”

Crusher scanned her, then Riker. Her expression shifted from concern to curiosity.

“You’ve both eaten recently.”

Riker blinked. “We ate at the feast.”

Crusher looked at Picard. “There are active digestive processes consistent with a meal consumed within the last several minutes. Proteins, carbohydrates, fats, sugars. Nothing toxic. Nothing synthetic that I can detect. It appears to be ordinary food.”

Picard looked at Riker. “You were gone thirty-two minutes.”

Riker shook his head. “Captain, from our perspective, we were gone for hours. Transport to London, the train ride, arrival at the school, the feast, the meeting with Potter.”

Geordi looked up sharply from Data’s diagnostic. “Hours?”

“At least,” Riker said. “The train ride alone felt like half a day.”

Data turned slightly. “My internal chronometer recorded two conflicting durations. The primary processor indicates thirty-two minutes and fourteen seconds elapsed from transport to return. My episodic memory index contains sequential observations spanning approximately six hours and forty-one minutes.”

Geordi frowned. “That shouldn’t be possible.”

“I agree,” Data said.

Crusher closed her tricorder and looked toward Picard. “Physiologically, they experienced more than half an hour. I can’t say how much more. But Will and Deanna both show signs of having been awake, walking, eating, and emotionally stimulated for longer than thirty-two minutes.”

Picard absorbed that without comment.

Geordi tapped his padd and placed it on the briefing table, activating the wall display. The planet appeared, blue-white and familiar.

“I also have something else,” he said. “After you returned, the captain ordered a new sensor sweep. We ran it three times.”

The image shifted.

The overlays changed.

No lifesign markers appeared.

Picard stood slowly. “Report.”

Geordi’s voice grew more subdued. “The entire planet is now devoid of activity. No lifesigns. No human population. No animal lifesigns. No plants that I can positively identify as living organisms. Nothing in orbit not even the primitive satellites and debris.”

Riker rose from his chair. “That’s impossible.”

“That word is getting a lot of use today,” Geordi said. “Power systems are still active in major cities. Electrical grids are running. Streetlights, computer networks, broadcasting towers, some automated signals. But there’s no movement on the surface. No vehicles. No aircraft. No trains. No people.”

Troi went pale.

“I felt them,” she whispered.

Crusher looked at her. “Deanna?”

“I felt six billion minds from orbit. Then thousands at the school.” Her eyes remained on the dead planetary image. “They were there.”

Data spoke quietly. “Or they were simulated at a level sufficient to affect Betazoid empathic perception.”

Picard clasped his hands behind his back. “Could the entire planet have been a simulation?”

Geordi hesitated. “If it was, it fooled everything we have. Weather systems, oceans, power grids, satellites, chemical signatures. But now…” He shook his head. “Now it’s like someone turned the people off and left the lights on.”

Riker looked toward the window.

The planet below looked unchanged.

Blue oceans. White clouds. Sunlit continents.

A living world with no life.

Picard turned from the display. “Mister Data, the power signatures?”

“Still present,” Data said. “The faint energy pattern remains distributed across every celestial body in the system. However, the signature is no longer masked by population data. It appears significantly more complex than previously observed.”

“Meaning?”

Data paused. “Meaning that what we first interpreted as planetary power signatures may have been only the surface layer of a larger system.”

“A larger system,” Picard repeated.

Before Data could answer, the room filled with white light.

Not the shimmer of a transporter.

Not the clean geometry of a hologram.

A flash.

Bright, theatrical, and entirely unwelcome.

Q appeared standing on the briefing table.

He wore a Starfleet captain’s uniform that was close enough to regulation to be insulting, with Picard’s rank pips and a smug expression that suggested he had rehearsed the entrance.

“Jean-Luc,” Q said, spreading his arms. “I leave you alone for five minutes, and you wander into the monster’s system.”

Picard’s expression hardened. “Q.”

Crusher muttered under her breath, “Of course.”

Riker folded his arms. “Monster’s system?”

Q turned toward him with exaggerated delight. “Ah, Commander Riker. Still tall. Still bearded. Still rushing through doors marked ‘Do not open’ because someone dared you with a mystery.”

Picard’s voice cut through the room. “What do you know about this system?”

Q hopped down from the table, though his boots never made a sound when they touched the deck.

“I know you should not be here.” He looked around at them, his expression suddenly less playful. “None of you should be here. You should not have been able to detect this system for many, many more years.”

Data’s head tilted. “You are suggesting the system was intentionally concealed.”

“I am not suggesting anything, Pinocchio. I am telling you that every sensible species, continuum, collective, swarm, intelligence, machine-god, post-biological nuisance, and self-important cosmic bureaucracy gives this place a wide berth.”

Troi looked at him carefully. “Why did you call it the monster’s system?”

Q turned toward her.

For once, his smile did not reach his eyes.

“Because only monsters live here.”

Riker’s jaw tightened. “Harry Potter?”

Q’s nostrils flared faintly, as if the name itself irritated him.

“Is that the face he’s wearing today?”

Picard stepped closer. “You know him.”

Q gave him a sideways glance. “Everyone who matters knows of him.”

Troi said quietly, “I couldn’t get a true read on him at first. He appeared young. Human. Almost harmless.”

Q scoffed. “Harmless. How charmingly suicidal.”

Troi’s eyes narrowed. “Then his mask fell. Or part of it. I sensed age beyond anything I could understand.”

Q’s expression sharpened.

“There,” he said. “That instinct? Hold on to it. It may be the only intelligent thing anyone in this room has done today.”

Picard’s voice cooled. “You will explain yourself.”

“I will do better. I will give you the simplest advice in the universe.” Q leaned forward. “Leave. Now.”

Riker looked toward Picard, then back at Q. “Why? You said we might be destroyed.”

“No,” Q snapped. “You might be fortunate enough to be destroyed. Most ships that blunder into this system do not get so tidy an ending. They are pulled apart molecule by molecule, examined, catalogued, and disposed of. Sometimes the debris ends up under the lunar surface. Sometimes in the sun. Sometimes somewhere unpleasantly symbolic.”

A scoff came from behind them.

Everyone turned.

Harry Potter stood beside the briefing room windows, looking out at the blue curve of Earth below.

No flash had announced him.

No door had opened.

He was simply there.

Young face. Untidy black hair. Round glasses. Lightning scar.

And an expression of weary annoyance.

“Yes,” Harry said, without turning around, “because Q seems to think I am a binman and likes to throw his garbage into my system, and most of the time it arrives hostile.”

Q went very still.

Harry looked over his shoulder.

“Do you have any idea how long it takes to rake regolith on the moon back into its proper pattern after a plasma torpedo detonates on the surface?”

No one spoke.

Harry turned fully now, hands in his pockets.

“And before you pretend innocence, remember what I told you the last time.”

Q’s jaw tightened.

Picard stared between them.

Harry looked at Q expectantly.

Q’s voice dropped. For the first time Picard could remember, he sounded almost chastened.

“There is always someone older and with more power than you somewhere, so tread lightly.”

Harry tilted his head. “And have you learned that lesson?”

Q did not answer.

Harry sighed. “Of course not.”

Riker stared at Q.

He had seen the entity annoyed. Amused. Petty. Angry. Condescending. Even worried in flashes.

He had never seen Q quiet like this.

Q recovered some of himself and lifted his chin. “Are you going to talk to them?”

Harry glanced at Picard, then Riker, then Troi, then Data.

“I might.”

“That is unusually generous of you.”

“It’s not like they’ll really remember the visit.”

Troi’s expression changed.

Harry’s gaze shifted to Data.

“Well,” he said, “maybe one might remember.”

Data looked back at him.

Harry studied him for a moment longer, then his expression dimmed.

“No. Looking at you now, I don't think you will remember anything from this day either.”

Picard stepped forward. “You do not have the right to alter our memories.”

Harry looked at him.

The room seemed to grow very still.

“I have more rights than you have words for, Jean-Luc Picard.”

Q sighed theatrically, perhaps trying to reclaim some dignity. “And on that pleasant note, I think—”

“Go,” Harry said.

Q’s eyes widened. “Now, see here—”

Harry flicked his hand.

Q turned neon pink.

Not metaphorically.

Not by lighting effect.

Every inch of him, uniform included, became a vivid, luminous pink.

Crusher stared.

Geordi’s visor tilted.

Riker’s mouth fell open slightly.

Q looked down at himself in horror.

Harry made another dismissive motion.

Q vanished in a flash of offended light and a final huff that echoed faintly after he was gone.

Harry shook his head. “That man needs to learn some humility.”

Riker looked at the empty space where Q had stood, then at Harry.

“Could you make him more humble?”

Harry snorted. “I’ve known that man longer than the creation of Earth. If I could make him humble, I would have done it before your species climbed down from the trees.”

The room absorbed that in silence.

Longer than the creation of Earth.

Picard studied Harry for the first time without the distraction of crisis.

And something about looking at him was wrong.

Not visibly. The young man’s features were ordinary enough. Thin face. Green eyes. Messy hair. A scar. Robes that looked out of place against the sleek gray lines of a Federation starship.

But Picard felt, with sudden certainty, that he was seeing only the smallest possible surface of something vast. Like standing on a beach and mistaking the first line of foam for the ocean.

Harry pulled out a chair and sat down as if he had been invited.

“All right,” he said. “Ask what you want to know. If I feel like it, I’ll answer.”

Picard remained standing. “Who are you?”

Harry leaned back in the chair.

“That question always sounds simple to the person asking it.”

“Then simplify it.”

Harry looked amused despite himself.

“I am older than this universe,” he said, “and the previous two combined.”

No one moved.

Geordi let out a quiet breath. “The previous two universes.”

“Yes.”

Picard’s eyes narrowed. “And this solar system?”

“My ship,” Harry said.

Data blinked once. “The entire solar system is a vessel?”

“Was. Is. Sometimes I use it as a ship. Sometimes as a house. Sometimes as a memory. It depends on what I need.”

Riker looked out the window at the planet below. “You fly through the multiverse in a replica of Sol.”

Harry shrugged. “It was home once.”

Troi’s voice was quiet. “What do you do?”

The humor drained from Harry’s face.

“I am Death.”

Crusher’s eyes narrowed in disbelief. “Death.”

“Yes.”

“As in an entity associated with mortality?”

Harry looked at her with something almost like patience.

“I lead everyone from every civilization that has ever existed, and every civilization that will ever exist in this universe, to what lies beyond.”

Picard said nothing for a long moment.

Then, carefully, “You expect us to believe that.”

“No,” Harry said. “I don’t expect anything from you.”

Riker folded his arms. “That’s a very large claim.”

“So is the Federation.”

Data leaned forward slightly. “You are claiming to represent a metaphysical constant.”

“No. I’m saying I have a job.”

Crusher stared at him. “And the simulations? The school? The people?”

Harry’s eyes went to the window again.

“Memories.”

Troi felt the grief from him then, unshielded for a heartbeat, and nearly looked away.

“Those people were real once,” she said.

“Yes.”

“What happened to them?”

Harry’s voice was soft. “They lived, then died.”

The answer landed heavier than any tragedy he could have named.

Riker did not understand it completely, but some part of him felt the edge of it. To Harry, perhaps living itself was the tragedy and the triumph. Every life ending. Every civilization gone. Every face preserved because he could not stop remembering.

Picard sat slowly across from him.

“You said we are not ready. For what?”

Harry looked at him.

“For knowing how small you are without becoming afraid of the dark.”

No one answered.

Then Harry smiled faintly.

“Would one of you like to know? Just for a moment?”

Picard’s expression hardened. “Know what?”

“What it feels like to peer into the abyss of eternity and come out the other side.”

Troi’s face tightened. “That is not something to offer lightly.”

“I don’t offer anything lightly.”

Riker did not speak.

Neither did Picard.

Data, however, said, “If such an experience were possible, the neurological consequences for an organic mind could be severe.”

“Yes,” Harry said. “They could.”

Crusher looked at Harry sharply. “Then don’t.”

Harry gave her a strangely fond look. “Doctors.”

Picard leaned forward. “You have seen other civilizations.”

“All of them, eventually.”

“Then you know the Iconians.”

Harry’s expression shifted. “Yes.”

Data’s eyes sharpened. “The Iconian civilization collapsed approximately two hundred thousand years ago.”

“Collapsed,” Harry echoed. “That’s the word historians use when they do not want to say murdered, scattered, devoured by fear, and buried under propaganda.”

Picard watched him closely.

Harry continued, almost idly. “The Iconians built doors and thought distance was an insult. The Tkon rearranged stars and believed that made them wise. The Voth left Earth and forgot it because pride is more durable than memory. The Preservers collected worlds like frightened gardeners. The Hur’q carved hunger into history. Others still live beyond your maps, sulking in dark corners of the galaxy and pretending isolation is the same as survival.”

Riker looked up. “The Voth?”

Harry turned to him. “Dinosaur descendants. They left Earth about five million years ago. They reside in the Delta Quadrant now. Isolationist. Technologically sophisticated. Culturally terrified of being wrong.”

Picard absorbed that with visible interest. “They originated on Earth?”

“Yes.”

Riker glanced toward Data. “Is that possible?”

Data answered carefully. “There are gaps in Earth’s fossil record that could theoretically allow for an advanced saurian species to have developed and departed without definitive archeological evidence, but such a hypothesis would be extremely speculative.”

Harry smiled. “I visited them once.”

Troi looked at him. “What happened?”

“I offered to show them their origins.”

“And?”

“They tried to kill me.”

Riker stared.

Harry shrugged. “So I had to reprimand them like naughty children.”

Before anyone could respond, Worf’s voice cut through the comm.

“Bridge to Captain Picard.”

Picard tapped his combadge instantly. “Picard here.”

“Captain, a Borg vessel has appeared near the moon. It is on an intercept course with the planet.”

The room went cold.

Picard stood. “Red alert. We’re on our way.”

The klaxon sounded.

Harry remained seated for one extra second.

Then he sighed.

“Q.”

Picard shot him a look. “You believe Q brought them here?”

“I believe Q is very bad at cleaning up after himself, and he is probably mad about the color changing spell. I think I set it for 5 thousand years this time.”

They moved quickly out of the briefing room.

Harry followed them onto the bridge as if he belonged there, hands still in his robe pockets.

The main viewer showed a Borg tactical cube moving past the dead gray curve of the moon toward Earth. Its dark green surface pulsed with internal light. Massive, angular, and ugly, it advanced with the terrible certainty Picard remembered too well.

Worf stood at tactical. “Borg tactical cube. Weapons are charged. They are ignoring our hails.”

Picard took the command chair. “Shields up. Arm photon torpedoes.”

“Aye, Captain.”

Riker moved to his seat, though his eyes flicked once toward Harry.

Harry looked at the viewer, exasperated.

“End simulation.”

The bridge crew watched as the moon changed.

Then Earth.

The industrialized twentieth-century planet vanished like a painted veil.

Where oceans and continents had been, another world emerged.

It was still Earth in shape and mass, but its surface was covered with colossal structures that reached miles into the sky. Towers rose from continents in impossible geometries, their edges curved, folded, and angled in ways that made the eye struggle to follow them. Some buildings seemed to pass through themselves. Others twisted upward like frozen lightning. Vast bridges spanned distances too great for any material Picard knew, and lights moved beneath surfaces like stars trapped in glass.

The moon transformed as well.

Its gray surface became a city of white-black towers, ringed by structures that rose and sank in smooth, silent motion. One building stood out above all the rest: a long, spear-like tower extending several miles from the lunar surface, aimed directly at the approaching Borg cube.

Data’s hands flew over ops.

“Captain, the planetary transformation appears instantaneous. However, I am detecting no matter conversion, no holographic field, and no transporter event. It is as though our previous sensor readings were a perceptual overlay.”

Harry looked at the moon.

“Fire.”

The lunar tower ignited.

A beam lanced out, pale and vast, striking the Borg cube.

It did not explode.

It began to unravel.

Worf stared at his console. “The Borg are returning fire. Their weapons are having no effect.”

On screen, green cutting beams struck the moon and dispersed like rain against glass.

Data’s voice was quiet with astonishment. “The particle beam is disassembling the Borg vessel at the molecular level. The separated matter is being pulled toward the moon and stored beneath the surface.”

Riker watched, transfixed.

The Borg adapted. Frequencies shifted. Shields flared. Engines surged. Weapon ports opened. The cube tried to turn, to flee, to rotate, to regenerate.

Nothing mattered.

Layer by layer, the tactical cube came apart.

Outer hull. Structural lattice. Power conduits. Regeneration alcoves. Drones.

The ship was not destroyed in battle.

It was dismantled.

Picard looked at Harry.

The young man stood near the rail, staring at the viewer.

His face had gone distant.

He was there, on the bridge.

And not there at all.

Harry lifted one hand.

Palm up.

Offering.

No one moved.

Riker stood before he had decided to.

“Will,” Troi said, alarmed.

He knew he should not.

Every instinct told him not to touch the hand of the being who had just dismissed Q, ended worlds like simulations, and ordered the moon to take apart a Borg tactical cube as if swatting an insect.

He took Harry’s hand anyway.

The bridge vanished.

Riker stood inside the Borg ship.

The air was hot with ruptured conduits and green light. Alarms pulsed through the deck. The cube screamed in the mechanical silence of the Collective. Around him, the walls were peeling away into dust, layer by layer, not exploding but becoming less real with every passing second.

Harry still held his hand.

But Harry was also ahead of him.

And beside him.

And everywhere.

Riker watched him touch a Borg drone with both hands.

The drone froze.

For an instant, its cybernetic eye flickered. The implants across its skull spasmed. Its body was already turning to dust from the feet upward as the beam disassembled the ship around them.

Harry leaned close and spoke to it.

Riker could not hear the words.

But the drone’s face changed.

Not much.

Enough.

Then the body dissolved.

Harry moved on.

Riker was pulled with him.

Another drone.

Another touch.

Another unheard conversation.

Another body reduced to dust.

They moved through corridors that were being erased. Through chambers where drones turned toward them too late. Through alcoves where bodies hung half-awake. Through the heart of the cube as it came apart around them, its technology screaming uselessly against the moon’s patient hunger.

It seemed to go on for hours.

It seemed to take no time at all.

Harry touched each drone.

Every one.

No matter how damaged. No matter how assimilated. No matter how far gone. He stopped. He touched them. He spoke.

Some looked afraid.

Some looked relieved.

Some showed no expression at all.

But Harry spoke to each one as if they were not a component.

Not a unit.

Not a drone.

A person.

Riker’s throat tightened.

He had fought the Borg. Hated them. Feared them. Pitied them in moments he did not like admitting to himself.

He had never imagined this.

Not rescue.

Not destruction.

Something else.

Witness.

The cube grew smaller around them.

Corridors vanished behind them. The deck beneath their feet became dust and light. The last chamber opened before them, then unraveled. One final drone remained, its implants sparking, one human eye visible through the machinery.

Harry touched its face.

Spoke.

The drone closed its eye.

Then it was gone.

There was only light.

Harry turned to Riker.

“Do you understand now,” he asked, “what the infinite abyss of eternity really is?”

Riker tried to answer.

He could not.

He shook his head.

Harry’s expression softened.

“No,” he said. “You don’t.”

He let go.

Riker hit the bridge floor on his hands and knees.

He gasped hard, as if he had been drowning. Troi was beside him instantly, one hand on his shoulder. Crusher moved from the aft station, medical tricorder already open.

“Will!”

Riker could not speak.

His chest heaved. His hands shook against the carpet.

Worf drew his phaser and aimed it at Harry.

Harry barely looked at him.

With one small motion, he waved Worf’s arm aside.

The phaser did not fly away. Worf did not fall. But his arm moved despite his resistance, the weapon pointing harmlessly toward the floor.

“You really should not be in this system,” Harry said.

Picard stood slowly, fury and caution warring in his expression. “What did you do to him?”

“I showed him a fraction of my job.”

Troi looked up sharply. “A fraction?”

Harry’s face was unreadable.

“A fraction.”

On the viewer, the last particles of the Borg cube vanished beneath the surface of the moon.

There was no debris.

No wreckage.

No victory.

Just empty space.

Harry looked around the bridge.

“You will not be able to get back into this system until you are ready.”

Picard’s voice was cold. “And who decides that?”

Harry looked at him.

“I do.”

He lifted his hand.

The stars changed.

There was no acceleration. No warp field. No inertial shift.

One moment, the impossible Sol system filled the Enterprise’s sensors.

The next, it was gone.

The Enterprise was back on its previous course, stars sliding ahead on a routine heading as if nothing had happened.

Data turned to ops.

“Captain,” he said, “we are no longer in the anomalous system.”

Harry stood near the command rail, already beginning to look less solid.

“No one will remember what happened here,” he said. “Your minds are not capable of holding it.”

Picard stepped toward him. “You cannot simply erase—”

“I can,” Harry said. “And this time, I should.”

His gaze moved to Data.

“You might have remembered something. But looking at you now, more closely, I don't think you will.  I think you will be like them, and forget as well. That is a good thing my friend.”

Data looked at him, and for just a moment, something like concern passed over his face.

“Why?”

Harry smiled sadly.

“Because you would try to understand.”

Data seemed to have no answer.

Harry looked at them all one last time.

“Enjoy your day,” he said. “And remember, even if only in the shape of caution: there is always something older and more powerful out in the universe.”

His eyes settled on Picard.

“Tread lightly.”

Then he faded.

No flash.

No smoke.

No transporter effect.

He was simply less and less present until the space he occupied held only bridge light and air.

For several seconds, no one spoke.

Riker was still on the floor, breathing hard.

Troi helped him sit back against the base of the command rail.

Crusher scanned him. “Elevated heart rate, adrenaline spike, cortical activity consistent with acute sensory trauma.” She looked at him. “Will, can you hear me?”

Riker blinked.

“Yes.”

Picard looked toward Data. “Mister Data, report.”

Data’s fingers moved across ops.

“The system we were investigating is no longer present.”

Picard’s expression tightened. “No longer present?”

“There is no star system at those coordinates. Sensor records indicate an unremarkable region of interstellar space.”

Geordi turned from engineering. “That’s not possible. We were just there.”

Data looked at him. “I have no record of that.”

The bridge fell quiet again.

Troi looked down at Riker. “Will, what did you feel when you held his hand?”

Riker frowned.

“I was…” He stopped, searching. “I was somewhere else.”

“Where?”

“A ship. Borg.” His voice was rough. “No. Not a ship. It was coming apart. We were moving through it. He was touching them. Talking to them.”

Troi’s hand tightened on his shoulder.

“Who?”

“The drones.” Riker blinked hard. “Each one. Every…” His brow furrowed. “It felt like hours. But no time passed. He asked me something.”

Picard stepped closer. “What did he ask?”

Riker looked up at him.

His expression slackened.

“I…”

He looked around the bridge.

“What happened?”

Troi stared at him.

“Will?”

Riker looked at her, confused. “I’m sorry. I didn’t hear what you asked.”

Troi opened her mouth.

Then stopped.

Her own expression faltered.

“I don’t…” She looked toward Picard. “I don’t remember either.”

Crusher frowned. “Remember what?”

Picard stood in the center of the bridge, his face slowly settling into command because command was the only thing left when certainty failed.

“Mister Data,” he said, “are we still on our assigned heading?”

Data checked the navigational display.

“Yes, Captain. According to all ship records, we have maintained this heading for the last thirty-six hours.”

Picard’s eyes narrowed.

“Thirty-six hours.”

“That is correct.”

Geordi looked down at his console, uneasy. “No course deviations. No red alert. No anomalous system in the logs.”

Worf returned his phaser to his belt, though he looked uncertain why he had drawn it.

Picard looked toward the viewscreen.

The stars ahead were ordinary.

Silent.

Unconcerned.

“Very well,” he said at last. “Maintain course.”

“Aye, sir,” Data said.

Troi remained beside Riker for a moment longer.

He gave her a faint, confused smile.

“I’m all right.”

She wanted to tell him she was not sure any of them were.

But the thought slipped away before she could find the words.

Hours later, Will Riker entered his quarters.

The lights rose automatically. The room was quiet, ordered, familiar. A chair by the viewport. A table. A few personal effects. The soft hum of the Enterprise moving steadily through space.

He stood just inside the door for a moment, unsure why he felt so tired.

Then he saw it.

A single gold coin rested on the table.

Riker frowned and walked toward it.

It was old-looking, heavier than it should have been, marked on one side with the profile of a crooked-nosed goblin. Around the edge were words in a script that briefly made no sense, then seemed to resolve in his mind.

Gringotts Bank.

Riker picked it up.

A flash crossed his memory.

Stone walls.

A castle under stars.

A pale blonde girl saying, “No.”

A young man with ancient eyes.

A hand offered.

An abyss.

Riker inhaled sharply.

Then the coin crumbled.

Gold dust slipped through his fingers, dissolving before it reached the floor.

Riker stood alone in his quarters, staring at his empty hand.

For a long moment, he could not remember what he had lost.

Only that, for one impossible second, he had known it mattered.
