Mission: Port of Call
Location: The Echo Deck
Timeline: Mission Day 14 at 0830

The station had learned a steadier breath by the seventh day.

The welders’ staccato was gone from the lower decks, replaced by a patient hum that ran clean through the frame. Power relays no longer coughed at shift change; the promenade lifts had settled into a rhythm that felt practiced rather than provisional. Even the air seemed to move with intent now—circulating not because someone told it to but because the place itself had decided to live.

Theo could feel it in his steps as he climbed the last ladderwell to the unfinished observation chamber: a subtle buoyancy, as if the corridors had filled with a lighter gravity. He’d slept poorly, woke early, packed and repacked the same small kit twice, and drunk coffee that tasted like whatever the replicator thought “earthy” meant. He wasn’t ready to sit at the gate and watch clocks. He had somewhere else to be first.

The door yielded to his hand with the same soft sigh as before. Dust left crescent moons along the jamb where palms had pressed; someone had wiped a swath clear along the viewport, a streak of clean glass cutting through planetary grime. The same ribs arced overhead, but they felt less skeletal now, more like architecture than anatomy.

The piano waited where he’d left it, draped in its cloth—but not alone. A slim case sat beside the bench, its surface marked with looping Monean script like currents etched into stone. It was open. Inside lay an instrument shaped like the memory of a crescent moon: a shallow, arching frame strung with silvery filaments that gathered light the way water gathered sky. Where strings met frame, the air seemed to shimmer faintly, as if the instrument were exhaling.

“You came,” a voice said, and the word came full of tide.

Koa stood near the viewport, balanced with that effortless poise that made gravity look optional. The ridges at their throat held a thin, pearly luminescence—as if their body remembered the sea and had decided to carry a little of it in the skin.

“You said the space would remember us,” Theo answered. “I didn’t want it to keep only half the story.”

Koa’s gills flickered—a Monean smile, soft as a ripple. “I tuned the harp to your atmosphere,” they said, closing the case with reverent fingers. “It prefers the weight of water, but it will sing if we ask kindly.”

Theo drew the cloth from the piano, folded it once, and set it aside. The wood underneath had not changed. He liked that about it. He tried a single note—middle E again, as if completing a circle—and felt the room welcome it back with the same gentle, patient delay. The chamber remembered how to answer.

“How shall we start?” he asked.

“In the deep,” Koa said, lifting the harp, “we begin with a held tone so the water knows which story we are telling. Then we add currents. Here—” they tilted the crescent toward him, the strings catching the room’s pale light “—I think we begin the same way.”

They did not sit. The resonance harp was meant for a standing body, spine a mast, arms free. Koa’s left hand steadied the curve; the right hovered, then drifted to a low filament and drew a sound from it with nothing more than contact and patience. It was not a pluck. It was an invitation. The air vibrated in a narrow band Theo felt first at the bones around his ears, then in the sternum. The tone did not leap; it arrived, gathered itself, and lengthened until the room adjusted to it.

He answered with a chord so soft it barely registered as anything but warmth—a third and a fifth placed low, his foot on the una corda to thin the piano’s attack. The two voices found each other quickly, not in pitch but in intention: the harp’s tone shaping a path, the piano laying stones along it.

Koa shifted to a higher filament. The second tone brushed the first and set up a slow, shimmering interference that made the chamber seem to breathe twice at once. Theo eased his left hand into a progression, unhurried as a tide that knows the shoreline isn’t going anywhere. He left space—more than he would have with another human player—to let the after-sound gather into something the room could hold.

They spoke without speaking then. It felt like a conversation that had been waiting for words and discovered it didn’t need them. Koa would lean a fraction into a filament, and Theo would answer with a voicing that widened the field, letting the interference glow. When Koa damped a string, Theo released his foot and let the piano’s note die gracefully, as if closing a door someone might open again.

The soundscape they made was not quite a song and not quite an experiment. It was made of patience. Of trust. Of the kind of listening that rearranges the body from the inside out until you realize you’ve taken on the shape of the thing you’re hearing.

Koa’s tones climbed in a gentle spiral, not by steps so much as by pressure—like a diver rising hand over hand along a line in dim water. Theo followed in parallel, bringing the melody out of hiding a little at a time: a contour, then a phrase, then a line careful not to name itself before it was ready. A fragment of Satie offered a bridge. He didn’t push it. He let it dissolve back into the field so it could return later wearing a new face.

When the harp sounded near the top of its register, the overtone bloom in the chamber made light seem to loosen on the viewport, as if the stars had gone briefly out of focus to listen better. The ribs overhead gathered the resonance and passed it between them like an old story made new by a different teller.

Koa’s eyes were half-closed, their breathing shallow and even, the ridges at the throat brightening and dimming in time with the tones. “This is what air remembers,” they murmured, not quite under their breath.

Theo did not answer with words. He shifted the ground to the relative minor and watched the room change its color around them, the way a shoreline turned strange under a stormlit sky. Koa’s head tilted a degree, acknowledging the weather. The harp’s next tone arrived gloved in a faint roughness, as if the filament itself had picked up a memory while it wasn’t being watched. They stayed there longer than formality would dictate, not for drama but because it was the right place to rest.

It would have been easy to end on sentiment. They did not. They turned together instead toward clarity, walking their way back to the clean, slow pulse where they had begun. The return was not repetition. It was proof of distance traveled. When Koa reduced the harp to a single held tone again, Theo found the original chord from the first minute, placed it differently, and discovered that the room now gave it back with an answer it hadn’t known how to make before.

The last sound they made together didn’t end so much as resolve into a silence that felt earned. Koa’s hand hovered over the strings as they faded. Theo left his fingers resting on the cool ivory as the echo thinned from audible to known.

They stood in that quiet a long beat.

“In water,” Koa said at last, their voice softened further by what they’d made, “we say a song is complete when the sea sings it back to you. I think your station has learned a measure of this one.”

Theo let out a breath he hadn’t realized he’d been holding. “It learned faster than I did.”

Koa’s gills flickered again, a quick gleam; fondness, if he’d learned the signs right. “You learned to let air keep its shape while you asked it to move. That is no small lesson.”

He looked to the viewport. The smear of stars had sharpened, the glass newly cleaned or his eyes newly honest. Somewhere behind the blur, a transponder squawk would be crossing range. He could almost feel it, the way you felt weather coming when your bones had decided to trust the sky.

“How will your vessel sound?” Koa asked, following his gaze.

“Lean,” Theo said. “Quick. Like someone with more to do than time to do it.” He paused, listening inward as much as out. “But I hope her quiet is kind.”

Koa considered that. “Ships have personalities,” they said, an observation rather than a belief. “Our habitats do too. They learn their people’s breathing. They keep time with it.” Their fingers brushed the harp’s frame, a caress for a companion. “When you are aboard, bring your instrument’s quiet with you. The vessel will take it in.”

There was something like a chime then—soft, distant, stationwide. Not the urgent clip of an alert, just a pulse with an ending shape. It touched the bones of the room and the bones of him. He did not need to translate the words that would scroll on screens for those who wanted them. Sojourner inbound; Prepare for docking procedure.

Koa heard it too. The ridges along their throat dimmed to a cooler glow. “The tide turns.”

“It does,” Theo said, and found himself smiling—a small thing that felt earned.

They did not rush the rest. Koa laid the harp into its case with the same care as a sailor making fast a line, loose enough to breathe, tight enough to trust. Theo replaced the cloth over the piano, smoothing dust under his palm, setting the transport tag flat so it wouldn’t flap itself ragged in any small draft.

“Will you play again, out there?” Koa asked as they closed the case. The question held no claim, only a wish pointed like a compass.

“If there’s room to listen,” he said.

“There is always a room,” Koa replied. “Sometimes it is not made of walls.” Their gaze touched the side of his face and then the instrument and then the wide, bright dark beyond the viewport. “When your notes move the air, we will hear them where the water allows. There are currents between stars too.”

He inclined his head. “Then I’ll try to set them moving.”

Koa’s bow was small and old and meant. “Until our currents meet again, Theo.”

He did not offer a handshake—their last meeting had taught him the shape of Monean leave-taking was not held in palms. Instead he stepped back, and Koa stepped back, and the distance between them filled with what they had just made rather than what they were about to lose.

At the threshold, he lingered. The chamber had shifted again. Not its bones, not its dust, just its posture. It felt less like a room borrowed from a blueprint and more like a place with a story that had decided to keep going after the tellers left.

As if to prove it, the harp gave a faint tone in its case—unstruck. Not a sound so much as a memory of one, coaxed into audibility by the small change in pressure when the door’s seal broke. It hung for a heartbeat, sure of itself, then dissolved back into the new quiet they’d made.

He carried that tone with him through the corridor’s curve, past crates with handwritten labels in three alphabets, past a pair of engineers speaking in low, satisfied cadences, past a viewport where a child pressed both hands to the glass and fogged it with a gasp before moving on. The station’s hum took up the note and wore it like a thread, subtle and persistent.

At the junction for the docking arm, the crowd thickened: luggage on trolleys; uniforms crisp and rumpled; bodies that smelled of metal and soap and the sweet, unmistakable salt that meant a Monean had just passed by. Above it all, the soft voice of an announcement promised order in a language that asked to be trusted.

Theo paused before the turn. He did what he always did when decision pressed—checked the inventory inside himself. The small ache at the base of his left thumb was a bright line of information: he’d been playing again. The steadiness in his chest was another: he had been heard. The restless itch in his legs was gone, replaced by a readiness that felt like the second before a first breath.

He stepped into the flow. The hum of the station folded around him and—just for an instant—resolved into a key he recognized from the chamber. It might have been accident. It felt like kindness.

Ahead, Sojourner waited, unseen but present in the architecture, the way a melody lived in the body before a hand ever found the note. He thought of Koa’s phrase—there are currents between stars—and let it fix itself somewhere useful inside his head.

Air, he thought, and water. Two ways of making motion. Two ways of keeping shape.

He walked on, and the ocean he carried with him kept time.
