Chapter 1 — The Order Was Reversed
Powder came back to herself the way a limb comes back from being slept on — the pins-and-needles wrongness first, then the dull realization that the thing was hers to begin with.
Cold. That was the first honest thing. Not the shivering kind; a deeper, chemical cold that had been pumped into her marrow and was only now sludging out. Her tongue was a dead weight. Her eyelids weighed a pound apiece and opened to a curved ceiling of frosted acrylic three inches from her nose, her own breath fogging it in slow, wet blooms.
Right, she thought, with the fuzzy patience of someone reassembling herself from parts. The pod. The very expensive pod.
A voice threaded down through the ship's bones, tinny and unbothered, the sound of a person who had said this a thousand times and would say it a thousand more.
"—arrival. All personnel, your journey is complete. Elapsed transit time from Earth: five years, ten months, and seventeen days. Welcome to the Alpha Centauri system. Welcome to Pandora."
Something behind Powder's sternum did a small, ridiculous flip.
Five years, ten months, seventeen days. She'd slept through most of it and it still felt like it had taken her entire life to get here, because in a way it had. She'd been a kid staring at a screen when the first real footage came back — not the sanitized promo reels but the raw feed, an animal the size of a house moving on six legs in a way that shouldn't have worked, that violated every scaling law she'd later spend a career trying to understand. Everyone else in the room had gasped at how big it was. Powder had leaned in close enough to fog the glass and thought: but how. How does a body that size not tear itself apart moving that fast.
She'd been asking the question ever since. She was about to be standing inside the answer.
Her hands found the harness buckles before her brain had fully signed off on the plan. The straps hissed loose. Around her, other pods were still sealed, their occupants floating pale and slack, and the medical bay was drifting with techs in soft-soled boots who had a whole choreographed sequence for waking people up — a sequence that did not, apparently, account for people who woke themselves up.
Powder pushed off. The lack of gravity turned it into a lazy, tumbling drift toward the aisle, and she overcorrected, and her shoulder clipped a monitor arm hard enough to send it swinging.
"Whoa — hey." A tech kicked over, catching the arm, catching her elbow, steadying both. Young guy, tired eyes, the look of a man who had chased a lot of impatient scientists across a lot of zero-g rooms. "You're supposed to wait for us to clear you."
"I feel great," Powder said. Her voice came out gravel-rough and about an octave lower than she remembered it. She cleared her throat. "Ish. I feel ish."
He checked a readout on his wrist monitor, thumbed her eye wider to shine a light in it while she squinted and endured it. His mouth did a small dubious twist that she recognized, because she made it at prototypes right before they failed.
"...Pupils are fine. Reflexes fine. You're clear." He let go of her elbow. "Storage is that way. Grab your gear, get dressed, mask up when they tell you. And—" he glanced at the manifest floating on his wrist, and his brows went up a fraction. "Doctor. Sorry. Didn't clock the name."
"Don't apologize, it's a stupid name." She was already drifting toward the hatch, catching handholds hand over hand, her body remembering how to move even while her head lagged behind.
She left him blinking after her.
The drop from the orbital transfer ship to the surface was, in Powder's expert professional assessment, an act of psychological cruelty.
Not the physical part. The physical part she could have written a paper on — the way the shuttle bit into the upper atmosphere, the sustained press of deceleration flattening her into the seat, the specific frequency of the hull's shudder that told her more about the airframe's tolerances than any spec sheet would. She catalogued all of it automatically, fingers drumming a fast, irregular beat against her thigh, one knee bouncing, because sitting still had never once in twenty-eight years been a thing her body agreed to do.
The cruelty was that there were no windows.
Somewhere on the other side of that hull was Pandora — an entire living world, the thing she had crossed four light-years and technically slept through a chunk of her thirties to reach — and she was strapped into a rattling metal box staring at the back of a stranger's headrest, close enough to touch a whole biosphere and unable to see so much as a cloud of it.
"On landing," the foreman called down the rows, voice flat over the noise, "you mask up before the ramp drops. No exceptions. Exolung on, seal checked, then you move. You do not stroll. You do not sightsee. Pandoran air will put you unconscious in about twenty seconds and dead in about four minutes, and it does not care how important you are back home. Cross to processing, fast, stay in the group. Questions get answered inside."
Powder pulled the mask on, worked the seal against her cheekbones, felt the small negative-pressure tug that meant it was live. Her fingers moved through it neatly, no fumbling — she'd drilled this until it was reflex, the one part of orientation she'd taken with grim seriousness, because suffocating on an alien world before she'd learned anything from it struck her as the single most Jinx way to die she could imagine. Of course it broke. Of course the seal failed. It's me.
She snorted behind the mask. Nobody heard it.
The ramp dropped.
For one heartbeat — one — the gap between the hull and the processing building opened up and Pandoran daylight poured through, thick and green-gold and strange, and she got the smell of it even through the filters, mineral and wet and alive. Her whole chest went tight with it.
Then the wall.
Bridgehead City had swallowed the horizon. She'd known, abstractly, that the settlement was fortified — she'd seen the schematics — but the schematics hadn't prepared her for the sheer insulting scale of it, a sheet of grey composite rising up and up until it cut the sky off clean. She jogged across the open apron in a herd of masked strangers, boots ringing on scored metal, and she could not see one single tree. One. She was on Pandora and all she could see was a wall.
Later, she promised herself, ducking through the processing doors as they sealed the outside away behind her. Later I see everything.
The safety briefing was where the day tilted.
It started fine — better than fine. Powder liked being lectured about danger the way some people liked ghost stories, and the officer running the room had a solid list of ways the planet could kill you. The atmosphere: the usual nitrogen, oxygen, and carbon dioxide but also hydrogen sulfide, xenon, and methane, don't breathe it. The flora: neurotoxins, corrosives, a fern-thing that could digest metal. The fauna, with slides — and here Powder leaned forward without meaning to, elbows on knees, drinking it in. A viperwolf's jaw articulation. The wing-loading on a mountain banshee. A thanator's stride caught mid-frame, and God, look at the hips on it, the load path through that pelvis, she could stare at that for a week —
Then the officer clicked to the next slide, and the tone changed, and Powder's eyes narrowed.
"—the indigenous population. The Na'vi." A slide of one of them, tall and blue and beautiful even in a bad tactical photo. "Hostiles. You will encounter them primarily as a threat outside the perimeter. They are territorial, technologically primitive, and aggressive toward human expansion. Standing orders: you do not engage, you do not approach, you report and you fall back to a defended position. Treat contact as a combat situation until told otherwise."
Hostiles. Powder sat very still, which for her was a whole event.
Because that wasn't the story. That wasn't the story at all. Back on Earth — for decades now — every scrap of news about Pandora had been the same warm, glossy note: cooperation. Cultural exchange. Two peoples finding common ground. The Avatar program held up as proof, hands across the void, look how well it's going. She'd half-signed up on the strength of it, the idea of listening to something instead of just dismantling it.
And here, five years and change later, a bored officer in a grey room was flipping past a slide of a living figure and calling them a hostile like they were a strain of the fern that ate metal.
Somebody's story was a lie. Either the one they'd sold her across four light-years, or the one being sold to her right now. Powder was extremely good at spotting the moment two datasets refused to reconcile, and this was that moment, ringing like a struck glass.
She didn't raise her hand. She didn't say the blunt thing — for once, she felt the shape of it forming in her mouth and swallowed it, because she'd just gotten here and she didn't yet know the room, didn't know who profited from which version, didn't know enough. That, more than anything, was the tell that she was rattled: Powder, keeping her mouth shut.
She filed it. She sat through the rest with her jaw set and her fingers gone still on her knee, and she thought: I am going to find out what's actually happening here.
Her quarters, at least, apologized for the day.
Being the foremost living expert in biomechanics turned out to buy a person a room roughly four times the size of anyone else's, with a real bed instead of a rack, a workstation, a window with an actual view of the interior compound, and a door that locked and was hers. Powder dropped her single bag on the floor, stood in the middle of all that space, and felt the specific hollow amusement of luxury that had followed a genuinely miserable briefing.
On the nightstand she set the one thing she'd hand-carried the whole way: a small, scuffed photo in a cheap frame. Two girls, one blue-haired and gap-toothed and maybe eight, one older with a fighter's grin and knuckles she'd clearly used. Powder looked at it for a second. Touched the red lock at the side of her own head without quite noticing she'd done it — the dyed streak she'd worn for ten years now, a small stubborn red mark against all that blue.
You'd hate it here, Vi, she thought dryly. Walls everywhere. No windows. A beat. You'd have punched that officer, though.
Then she straightened, rolled her shoulders, and left the room. She hadn't come four light-years to look at a photograph. She'd come to link.
The Avatar compound sat apart from the rest of Bridgehead, pushed right up against the tree line so that the far fence seemed to dissolve into actual, un-walled, breathing forest — and that was the first thing on this whole planet that lived up to the footage. Powder slowed as she walked into the main room lined floor to ceiling with reinforced windows: real Pandoran canopy finally in view, close enough to throw a rock at, layered green going purple in the depths.
"You're the biomech."
The voice came from a woman leaning in a doorway with a cigarette hanging off her lip like it had grown there. Red hair loose above her shoulders, eyes that had done a lot of not-suffering-fools, a lab coat worn like armor. She looked Powder up and down the way Powder looked at cadavers — thorough, unsentimental, pricing out what's useful.
"Grace Augustine. I run this circus." She didn't offer a hand. "You're smaller than your reputation."
"Everything's smaller than my reputation," Powder said. "That's why I keep the reputation."
The corner of Grace's mouth twitched, which Powder would later learn was the woman's version of a standing ovation. Grace pushed off the doorframe and started walking, and Powder fell in beside her, and the questions came without preamble.
"Link hours."
"Six-forty, logged. Six-sixty if you count the sim runs the board wouldn't certify."
"Language."
"Reads well, tests well. Academic." Powder made a face. "Which means I can conjugate anything and probably can't order lunch. I know how that goes."
"Good. At least you know it." Grace exhaled a stream of smoke to the side, sharp eyes cutting over. "Half of them show up thinking a semester makes them fluent. It makes them loud." She stopped at a bank of link units — coffin-sized, hinged open, gel-lined, humming faintly. "You've done the induction a hundred times in sim. This is the same, except it's real, so it'll feel completely different and you'll hate the first thirty seconds. Everybody does. Get in."
Powder looked at the open unit. She'd been looking at pictures of this exact moment, or something like it, since she was a kid fogging a screen with her breath.
The order was reversed, she thought — not for the first time. Most scientists picked a field and then found their subject. She'd found Pandora first, this impossible body of a world, and become a scientist just to get close enough to ask it how it worked. Everything since had been the long walk here.
She climbed in. The gel took her weight, cool and yielding. She settled her head into the cradle, felt the sensor array kiss her temples, and let out a slow breath.
Just like the training. Let it drift.
She closed her eyes.
She opened them somewhere else, and the first thing — the very first thing, before anything else — was how loud the world got.
Not sound. Everything. Her new eyes pulled detail out of shadow that human eyes would've called black. A draft moved across skin that felt every degree of it. She could smell the room in layers — antiseptic over metal over something green leaking in from outside — and hear, distinctly, two separate heartbeats that were not her own. Her senses had been turned up to a setting she hadn't known existed, and it was glorious, and it was a lot, and she lay there for a second just being flooded.
Then she flexed a hand and watched long blue fingers close, and something in her professional soul quietly lost its mind.
The techs were patient with her. Follow the light. Squeeze. Push against my hand — no, don't dislocate my shoulder, easy — good. Track the reflex hammer. She overshot every early movement, the way you do in a body with more reach and power than the last one, and each overshoot was a data point she couldn't help grinning at, mapping the new proprioception in real time, scaling laws, live, from the inside.
Somebody eventually put a shirt and a pair of shorts in her hands to replace the medical gown, and she got upright — tall, absurdly tall, her center of mass in a whole new place — dressed with more coordination than she had any right to this fast, and walked out into the compound on her own two enormous feet.
The forest was right there.
The avatar compound had its own little world tucked against the trees: obstacle courses for training the new bodies, a green sprawl of farm plot, a scuffed rec area where someone had bolted a basketball hoop at a height that made sense for people three meters tall, and where two avatars were trading lazy shots and trash talk in the thick gold light. Someone laughed. A bird-thing she couldn't name called out of the canopy and got an answer.
Powder walked out to the edge of the clear space, where the maintained ground gave way to the real, dense, un-walled forest — and she stopped there, and she drew a slow breath all the way down into these new, larger lungs, and held it.
Held it, and looked, and felt the whole staggering living scale of the place come up through the soles of her feet.
She'd waited her entire life to stand exactly here.
Okay, she thought, and let the breath go, and felt the first real grin of the day break across a face that wasn't quite hers yet. Okay. Now show me how you work.
