Ryland Grace had carved out an existence on Erid that few humans could fathom. Years had slipped by since the Hail Mary’s desperate landing, its mission to combat the astrophage scourge a fading but foundational memory. The planet Erid had since then become his home. The Eridians - brilliant, crystalline beings who communicated through intricate patterns of light and vibration - had welcomed him as a savior. Grace couldn’t care less about his title though, as Rocky was all he had ever and would ever need.
The habitats built for Grace were marvels of collaborative engineering: reinforced domes and tunnels where Earth-like air circulated, gravity plates eased the strain on his body, and bioluminescent panels mimicked the soft glow of a distant sun. He spent his days in vast laboratories, collaborating with teams of Eridians on everything from refining astrophage-resistant propulsion to mapping the long-term ecological recovery of both their worlds. Evenings often dissolved into long sessions of mutual education. Grace taught them about humanity’s messy emotions, its fragile biology, and its stubborn resilience. In return, the Eridians shared their mastery of vibrational physics and light-based computation, concepts that made human quantum mechanics seem quaint.
Rocky was ever-present. The Eridian’s multifaceted body, a symphony of shimmering facets and dexterous appendages, moved with purposeful grace through Grace’s quarters. “Grace needs consistent rest cycles,” Rocky had declared early on, his lights pulsing in emphatic patterns that Grace’s implanted translator rendered into clear, if slightly stilted, English. “Rocky watches. Ensures safety. Human sleep vulnerable - brain active, body still. Many risks.”
Grace had chuckled at first. “I survived cryo-sleep and interstellar isolation, Rocky. I think I can handle a nap.” But he appreciated the concern. It filled a void he hadn’t realized persisted even after the victory. Loneliness had been his shadow on the Hail Mary, a constant companion alongside the fear of failure. Here, anchored by friendship and purpose, that shadow should have retreated. Instead, it twisted into something new: frequent nightmares that clawed their way into his rest.
The first one arrived unannounced after a particularly grueling day. Grace and Rocky had spent hours dissecting human cardiovascular systems on a shared holographic display. Grace had sketched the heart’s four chambers with a stylus, explaining the rhythmic contractions, the valves, the coronary arteries. “This little fist-sized organ keeps everything going,” he’d said, tapping his chest. “Delivers oxygen, nutrients. But it can fail - blockages, stress, age. We call it a heart attack. Pretty nasty if it happens.”
Rocky had absorbed every detail, his body vibrating with questions. “Pumping organ vulnerable. Rocky understands. Will monitor Grace’s always.” The session ended late, Grace’s muscles aching from the heavier gravity. He collapsed onto the bed Rocky had custom-designed: layered polymers softened with scavenged fabrics from the ship, pillows contoured to human necks. Sleep came swiftly, pulled under by exhaustion.
Meanwhile Rocky maintained his vigil from a low perch near the bed. Over countless rest cycles, he had calibrated his senses to Grace’s baseline: the steady thump-thump of the human heart, a reliable percussion echoing through the chamber’s sensitive acoustics. It never varied during sleep - until tonight.
The acceleration was sudden. The beat quickened, erratic, pounding with unnatural force. Rocky’s entire form tensed, crystalline structures clicking sharply. He knew this pattern from Grace’s lessons. The heart - that vital muscular pump in the thoracic cavity - could spiral into crisis. Tachycardia. Arrhythmia. Heart attack. Blood flow compromised, oxygen starved from organs.
“No,” Rocky’s lights flashed in silent alarm. Friend in peril. He skittered forward on powerful legs, appendages extending toward Grace’s shoulder. The human’s face glistened with sweat, brow furrowed in unseen torment, chest heaving in shallow bursts.
Just as Rocky prepared to administer a gentle vibrational nudge - calibrated not to startle but to rouse - Grace jolted awake. His eyes flew open, wide with residual terror. For a heartbeat, the nightmare clung like frost. Then his gaze locked onto Rocky’s glowing facets. The familiar presence shattered the illusion. Relief flooded him, washing away the void’s chill. Grace exhaled shakily and fell back against the pillow, the bed creaking under the motion.
“Grace?” Rocky’s voice hummed urgently, lights pulsing in rapid sequence. “Grace okay? How feel right now? Heart noise… wrong. Very wrong. Rocky knows human organs. Heart pumps blood, delivers oxygen. Thinks damage possible. Must ensure Grace okay. Rocky fears for friend.”
Grace blinked rapidly, orienting himself in the dim glow of the habitat. The Eridian air recyclers hummed softly as Rocky’s bulk loomed close, concern etched in every vibrating line.
“Rocky? What… what’s going on?” He sat up slowly, rubbing his temples. Confusion creased his features. “My heart? You’re talking about my heart?”
Rocky could not stay still. He paced back and forth along the bedside, legs tapping a rhythmic pattern on the reinforced flooring. The motion betrayed his agitation; Eridians favored efficiency, but worry animated him fully. “Grace sleeps. Normal rhythm. Then heart accelerates. Fast, irregular. Never observed in prior cycles. Rocky watches always. Steady before. This time, anomaly. Rocky approaches to wake. Almost does. Then Grace wakes - breathing heavy, face showing fear. Rocky suspects heart attack. Grace taught: stops blood flow, damages muscle. Kills cells if severe.”
The explanation flowed in a torrent of modulated hums and flashing lights, the translator conveying the depth of his distress. Rocky paused, appendages gesturing helplessly as if seeking diagnostic tools. “Grace must confirm. Rocky needs truth.”
Grace swung his legs over the edge of the bed, bare feet meeting the cool, textured floor. The nightmare’s adrenaline still lingered, making his pulse feel elevated, but awareness returned. “Easy, Rocky. I’m okay. It was just a nightmare.”
Rocky halted mid-pace, tilting his upper body inquisitively. “Define, please. Why Grace appears terrified upon waking? Heart rate spikes dramatically. Matches symptoms Grace described once - heart attack indicator. Adrenaline surge, but could mask real issue. Grace one hundred percent positive?”
Grace managed a weary smile, reaching out to rest a hand on Rocky’s nearest appendage. The crystalline surface was warm, humming with latent energy. Contact like this had become their bridge over years of coexistence.
“A nightmare is a bad dream, buddy. Your brain sorts through junk while you sleep - memories, fears, what-ifs. Mine dragged me back to the Hail Mary, the isolation, the pressure. Not real. Just my subconscious playing tricks. The heart races because of the fight-or-flight response. Adrenaline dump. You remember that from biology, right? It’s normal after a scare, even an imaginary one.”
Rocky processed this, lights dimming in thoughtful patterns. “Brain creates false danger? No physical threat on Erid. Habitats secure. Astrophysics contained. Rocky and Eridians protect. Yet body reacts as if combat.”
“Exactly,” Grace affirmed gently. “It’s the mind’s way of processing trauma. The mission left scars. Loneliness out there… it lingers.”
But Rocky pressed, circling back with characteristic thoroughness. “Heart attack possibility remains. Grace explained rarity at current age. Stress, diet, genetics factors. Not guaranteed later. But spike concerning. Grace sure? One hundred percent?”
Grace laughed softly, the sound easing the tension. “I promise, Rocky. I’m healthy. The Eridian medical teams have scanned me more times than I can count. Heart’s strong, all systems nominal. That lesson I gave you? It was to explain limits, not predict doom. I’ve got plenty of time left. Decades, hopefully. You’re stuck with me pal, I’m not going anywhere soon.”
Rocky remained silent for several moments, internal computations whirring. Trust in Grace’s expertise ran deep, forged in shared survival against cosmic odds. “Remembers lesson clearly. Grace safe now. But… precaution. Next sleep cycle, monitoring enhanced. If not Rocky personally, then qualified Eridian. Eases concern.”
Grace nodded without hesitation. “If it helps you feel better, absolutely. Deal.”
“Deal,” Rocky confirmed, lights brightening with relief.
In the months that followed, life on Erid deepened into rich routine laced with wonder. Grace’s integration expanded beyond the labs. He participated in Eridian communal gatherings, where thousands of crystalline forms synchronized their emissions into breathtaking light symphonies. His suited figure, a curiosity among the Eridians, drew younglings who flashed eager questions whenever they had the chance, much to Rocky’s annoyance who wanted to be able spend time with his friend by himself sometimes.
Grace and Rocky shared meals and conversations meandered through philosophy and science. Grace recounted Earth’s chaotic beauty: crowded cities, unpredictable weather, the simple joy of a simple bike ride through nature. Rocky shared Erid’s collective memory, how the astrophage crisis had unified their society in ways previously unimaginable.
Yet the nightmares persisted, arriving like uncharted comets. Grace documented them in private logs, holographic entries that Rocky occasionally reviewed with permission. One involved the comet Taí, its icy surface cracking underfoot as systems failed. Another replayed his amnesia, waking in confusion aboard the ship with no memory of his purpose. Each left him gasping, heart racing, sweat-soaked.
The Eridians adapted with communal efficiency. A rotation of monitors - scientists versed in human physiology from Grace’s teachings - stood watch during rest cycles. Non-invasive resonance scans tracked vitals, feeding data to Rocky’s personal interface. It felt invasive at first, but Grace recognized the love behind it. “You all turned a lone astronaut into a village project,” he joked to Rocky one day.
“Grace worth project,” Rocky replied simply.
Scientific collaborations flourished amid this. Together, they refined models for Earth’s recovery, simulating centuries of climate stabilization using Eridian computational arrays. Grace taught advanced biology seminars, delving into neurology to explain nightmares themselves: the amygdala’s overactivity, the hippocampus replaying threats. Rocky countered with Eridian equivalents - vibrational echoes that lingered in their crystalline matrices post-trauma.
Flash forward several months. The nightmares had become less frequent but no less intense. Grace had thrown himself into a major project: designing hybrid education modules for potential future human visitors to Erid. Exhaustion claimed him after a marathon session, and he retired to his quarters with Rocky nearby, as had become custom.
Sleep pulled him deep. The dreamscape warped into horror. He was adrift in the void again, the Hail Mary a distant speck. Voices called - Earth’s billions, Erid’s populations - accusing him of inadequacy. Then it warped and he was back on Earth, being held down on to the grass, restrained and about to be sent off to die.
A yell built in his throat, raw and desperate, as the cold consumed everything.
Grace awoke with a violent start. The yell tore from him, cutting off sharply as consciousness slammed back. His body jerked upright, sheets twisted, heart thundering in his ears. Panic clawed at his chest, vision swimming with afterimages.
Rocky was there in an instant, positioned at the bedside with unwavering presence. No frantic pacing this time; experience had tempered his response into calm assurance. His lights glowed steady and warm, vibrations gentle. “Grace safe now,” Rocky intoned, the words carrying the weight of repeated reassurance. “Grace home.”
The simple declaration pierced the lingering fog. Home. Not the sterile corridors of the Hail Mary, not the uncertain future of a dying Earth, but here - on Erid, surrounded by light and loyalty. Grace reached out, pulling Rocky into an embrace. His arms wrapped around the Eridian’s sturdy form, appendages curling reciprocally in careful reciprocity. The contact bridged biology and crystal, human frailty and alien strength. “Thank you,” Grace whispered, voice thick with emotion. “Thank you, Rocky.“
They remained like that for long minutes, the habitat’s systems humming a quiet lullaby. No further explanations were demanded. Rocky simply existed as anchor, his presence a shield against the mind’s betrayals.
The tapestry of their years on Erid wove richer with each cycle. Grace’s nightmares, once harbingers of isolation, transformed into catalysts for deeper connection.
Grace explored shared storytelling sessions with Eridians turning personal histories into collective strength; Grace’s tales of human perseverance inspired new light-art depicting cross-species triumph.
Daily life brimmed with detail. Mornings began with atmospheric checks and light breakfasts, Rocky critiquing nutrient balances. Labs buzzed with activity.
Evenings deepened bonds. They overlooked engineered valleys where native flora, bolstered by astrophage countermeasures, bloomed in crystalline splendor. “This is what we fought for,” Grace murmured once. Rocky agreed: “And live for.”
The first nightmare’s memory lingered fondly in retrospect - a turning point. Rocky’s initial panic had revealed the depth of his care, human biology lessons becoming tools of friendship rather than abstract data. Subsequent incidents reinforced it, each awakening met with “Grace safe now. Grace home,” until the phrase became a ritual of healing.
Grace’s logs evolved from documentation to reflection. “Trauma doesn’t vanish,” he wrote. “But community dilutes it. Rocky and the Eridians gave me what the Earth never could: belonging.”
In quiet moments, he pondered the future. Earth signals grew stronger with new relays; someday, others might join him. But for now, his place was here, heart steady in the company of friends who monitored its every beat - not out of clinical duty, but love.
As the habitat lights dimmed for another rest cycle, Grace lay back, Rocky nearby. Nightmares might return, but so would the light. On Erid, Ryland Grace slept toward dawn, anchored across the stars.
