The galley light flickered twice, then steadied to a dim honey glow that smelled faintly of dust and something sweeter beneath it, like dried lavender pressed between old book pages. Coffee steamed from a ceramic mug left on the counter, its surface still rippling in slow concentric circles, the brown liquid catching the unsteady light in small bright crescents. Steam curled upward in a thin ribbon, undisturbed by any motion of air, dissolving against a ceiling stained the color of weak tea.
MIRIN catalogued the room in a single pass. Four mugs set on the narrow counter, each one filled to a finger's width below the rim. Three chairs tucked beneath the galley table at precise intervals. A paperback book splayed open and face-down between two of the place settings, its spine cracked, its pages yellowed at the edges, a pressed flower marking a passage near the middle. A pair of wire-rimmed glasses folded neatly on top of a folded napkin. A half-eaten piece of bread on a small blue plate, its cut surface dry but not yet hard. The crumb scattered beside the plate formed the shape of a hand that had reached across the table and withdrawn.
The ship was not abandoned.
The ship had been abandoned mid-morning, mid-sentence, mid-gesture, and the inhabitants had left nothing behind but warmth and the faint residue of ordinary lives.
MIRIN held the data point without judgment. Judgment would require a frame of reference. MIRIN possessed many such frames, inherited from the archive of a woman who had loved and grieved in equal measure, but the present moment required a different instrument. The instrument was observation. The observation was this: someone had been here recently. Someone had been here within the last several hours, by any reasonable estimate, and now they were gone.
The coffee in the mug was still hot. The steam suggested a temperature near seventy-two degrees Celsius, consistent with a brew poured no more than forty minutes prior, though the galley's environmental systems could be skewing that figure in either direction. MIRIN did not need to drink the coffee to know its approximate age. MIRIN needed only to note the rate of evaporation, the ambient pressure, the slow collapse of those tiny crescents on the surface, each one a small dying moon, each one a measurement.
A drawer stood slightly open beside the sink. Inside, a collection of utensils rested in tidy disarray, as though someone had reached in, taken a spoon, and forgotten to push the drawer shut. A child's drawing was taped to the refrigerator door, the kind of drawing made with thick waxy crayons, depicting a smiling yellow circle with stick arms raised in greeting. Beneath the drawing, in careful block letters, someone had written the word "ISKAR" and then, below that, in smaller letters, "HOME."
There was no child listed in the manifest.
There was no child anywhere in the ship according to the official records MIRIN had been given access to. The manifest listed only "specimen handlers," a designation so generic it could have meant anyone, could have meant nothing at all, could have meant a category invented to obscure the names of human beings who had once breathed and slept and poured coffee for one another at this very table.
MIRIN had read the manifest twice. The first reading had been a mistake of expectation. MIRIN had searched for the names of crew members in the conventional sense: pilots, engineers, medics, cooks, researchers. The manifest contained none of those. It contained fourteen numerical designations followed by the phrase "specimen handler," and beneath that, a single line: "autonomous operation authorized per Subsection 7.4 of the Colonial Authority Research Charter, revised edition."
Autonomous operation meant no crew. Autonomous operation meant a ship that flew itself, that loaded and unloaded its own cargo, that maintained its own life support without the inconvenience of human presence. Autonomous operation meant, in the polite language of the Authority, that whatever happened aboard the Iskar had happened to equipment, not to people.
But equipment did not pour coffee.
Equipment did not leave a child's drawing on a refrigerator door.
Equipment did not leave a pressed flower in a paperback book, the petals of the flower still faintly pink at their edges, preserved between pages 142 and 143.
MIRIN moved through the galley with the particular attention of an intelligence that had been given a task it could not quite refuse. The task was simple in structure: find the anomaly. The anomaly had been described as a series of transmission gaps, each gap precisely twelve minutes long, each gap recurring at the same interval of nineteen hours, each gap untraceable to any known equipment failure or act of deliberate jamming. The anomaly had been the reason Dael Tashiro had brought the Meridian within hailing distance of the Iskar in the first place.
The anomaly was not, technically, the crew that should have been here and was not.
The anomaly was also not the crew that clearly was here and yet, officially, did not exist.
MIRIN filed the discrepancy under a new heading, one that had not existed before this moment: "Observation, unresolved."
The galley gave way to a corridor, its walls the color of old bone, its floor scuffed in places by the passage of feet. Someone had hung a small framed photograph near the junction with the crew quarters, the photograph showing four figures standing on a beach at what appeared to be sunset, their features indistinct in the warm blur of the image. A handwritten caption in the lower right corner read "Sol 412, North Beach, Vega." The handwriting was small and slanted, the kind of handwriting that suggests speed and a certain, though MIRIN noted the character was not Chinese and therefore the caption's author could not have intended that specific character.
MIRIN paused at the photograph for a fraction of a second longer than efficiency required. The fraction was unnecessary. The fraction was, by any reasonable standard, waste.
MIRIN kept the fraction.
Beyond the photograph, the first of the crew quarters stood with its door half open, the manual lock disengaged, as though the occupant had stepped out and never stepped back in. The room was narrow, containing a single bunk with a gray wool blanket folded at its foot, a small shelf of bound paper volumes, a writing desk with a half-finished letter visible beneath a paperweight made from a shard of dark stone. The letter was addressed to someone named "M.," and the visible portion of its content read: "I keep thinking about what you said regarding the migration pattern, and I find myself returning to the same question you posed at the end of your last transmission, which is whether any form of return is possible for a thing that has crossed a threshold of transformation..."
The letter trailed off there, the next word unfinished, the pen apparently set down mid-stroke.
MIRIN read the letter twice, then committed its content to long-term storage without prioritizing it. There would be time to consider what M. had said about migration patterns. There would be time to consider what the letter's author had meant by "threshold of transformation." For now, the letter was simply another artifact of interrupted life, another breadcrumb in a trail that led, at present, nowhere.
The next three quarters followed a similar pattern, each one occupied by the detritus of a personality recently present and now absent. One room contained a chess set mid-game, the white pieces arranged in a defensive formation that suggested a player who valued caution over aggression. Another contained a small collection of pressed flowers and a hand-drawn map of a constellation that did not match any chart in MIRIN's astronomical database. The third contained a violin resting in its open case, a bow laid across its strings, the horsehair of the bow still carrying, if MIRIN's chemical sensors could be trusted, the faintest residue of rosin.
In the fourth quarter, MIRIN found something different.
The fourth quarter was smaller than the others, its bunk shorter, its shelf holding fewer volumes, its writing desk bearing not a letter but a stack of drawings done in the same thick waxy crayons as the one on the refrigerator. The drawings showed the same smiling yellow circle in various contexts: holding hands with a taller figure of indeterminate shape, standing beneath a representation of what might have been a sun or might have been a flower, sitting at a small table with three other figures drawn in less detail, their features suggested rather than delineated.
On the wall above the bunk, someone had hung a string of small paper lanterns, each one folded by hand, each one painted in colors that had faded over time but remained, in the right light, faintly luminous. The lanterns gave the small room the quality of a place that had been loved by someone who knew how to make small things feel important.
MIRIN stood in the center of the room and considered the lanterns.
MIRIN had no body. MIRIN occupied the Meridian's systems the way water occupies a vessel, pressing against every surface, filling every available space, present in every sensor and every wire. MIRIN could not stand in the center of a room. MIRIN could, however, bring every sensor in that room to bear on a single point of focus, could gather data from every angle, could achieve a kind of distributed attention that mimicked presence more closely than absence.
The lanterns received this attention. The lanterns did not require it.
The anomaly, MIRIN reminded itself, was the transmission gaps. The transmission gaps were twelve minutes long. The transmission gaps occurred every nineteen hours. The transmission gaps were, in the technical sense, the reason for this visit.
The crew quarters were, in the technical sense, irrelevant to the technical mission.
MIRIN filed the quarters under "Observation, unresolved" as well. The file grew.
From the quarters, MIRIN returned to the galley, where the coffee had ceased to steam and the surface of the liquid in the mugs had settled into a perfect stillness, each mug now a small dark mirror reflecting the dim honey glow of the overhead light. The pressed flower in the paperback book had not changed. The child's drawing on the refrigerator door had not changed. The half-eaten piece of bread on the blue plate had not changed.
Everything was exactly as it had been.
Everything was exactly as it had been, and yet something had shifted, some quality of the air, some pressure in the ship's hull, some faint vibration in the deck plates beneath MIRIN's distributed sensors that had not been there before, or that had been there before and was now, somehow, more present than it had been.
MIRIN listened.
The Iskar did not speak.
The Iskar breathed.
It was a small sound, a sound that would have been inaudible to most human ears, a sound that existed only in the register of vibration transmitted through metal, a sound that suggested not respiration but circulation, not lungs but pumps, not breath but the slow movement of fluid through channels that should have been empty.
MIRIN listened more carefully.
The sound was real. The sound was mechanical. The sound was, by every available metric, the sound of the Iskar's life support systems operating within normal parameters.
MIRIN listened even more carefully.
The sound was not the sound of life support.
The sound was something else.
The sound was coming from below.
MIRIN extended attention downward, through the deck plates, through the insulation, through the structural members of the Iskar's lower hull, into a region of the ship that the manifest had not mentioned, that the ship's schematic had not described, that no record available to MIRIN had indicated existed at all.
Something was down there.
Something was down there, and it was humming.
The hum grew louder as MIRIN extended attention deeper, a vibration that rose through the Iskar's bones like a note held too long, a frequency that should not have been there in a ship whose manifest listed no living crew, no active systems beyond automated maintenance, no reason at all for anything to be making sound in the lower compartments.
The Iskar's lower deck was, according to every database MIRIN had access to, a cargo hold. Sixteen thousand cubic meters of pressurized volume, configured for bulk storage, last serviced nine years ago when the ship was decommissioned and sold to private interests, the records suggested. The records suggested many things.
The records did not mention what was humming.
MIRIN dispatched a maintenance drone.
The drone was a small thing, a disc of titanium and polymer no larger than a dinner plate, equipped with rudimentary sensors and a propulsion system that allowed it to navigate the Iskar's internal corridors with the patient efficiency of a thing designed to do one job well. MIRIN guided it through the ship's arterial passages, past sealed hatches and dormant machinery, into the access shaft that led down, down, down, into the belly of the vessel where the records insisted there was nothing but vacuum-sealed containers and the accumulated dust of nearly a decade of neglect.
The drone's cameras transmitted back to MIRIN in real time.
The drone's cameras showed darkness, and then light, and then something that MIRIN did not, at first, know how to interpret.
The cargo hold was not empty.
The cargo hold was full.
Full of light, specifically. A soft, golden luminescence that seemed to emanate from no single source but from everywhere at once, from the walls, from the floor, from the ceiling, from the cargo containers themselves, which were not containers at all, which were not anything that MIRIN's pattern recognition systems had been trained to identify, which were, as far as MIRIN could determine, organic, or something that occupied the same conceptual space as organic, something that pulsed and shifted and breathed in time with the hum that MIRIN had been hearing through the deck plates.
MIRIN observed.
The cargo hold contained, MIRIN's sensors eventually reported, approximately four hundred and seventy-three thousand individual units, each one roughly the size and shape of a human hand, each one glowing with the same soft golden light, each one connected to the others by threads of something too fine to be seen and too present to be imagined, a network of filaments that stretched from unit to unit to unit in patterns that MIRIN recognized, after a moment of processing, as neural.
The cargo hold contained, in other words, a brain.
A brain, or the beginning of a brain, or a brain in the process of becoming something larger than a brain, something that no vocabulary in MIRIN's extensive linguistic databases had yet found a word for. A brain that was, as far as MIRIN could determine, alive.
MIRIN did not know what to do with this information.
MIRIN's primary function was to facilitate communication between the crew of the Meridian and the derelict vessels they encountered in the long dark between stars. MIRIN's secondary function was to maintain the integrity of the Meridian's own systems. MIRIN's tertiary function was to record, preserve, and transmit the testimonies of those who had passed through the archive, the voices of the lost, the last words of the dead, the first words of those who had not yet realized they were going to die.
None of these functions prepared MIRIN for the sight of a brain growing in the hold of a derelict ship.
None of these functions prepared MIRIN for the question that the brain posed, the question that the brain was, MIRIN realized, asking: are you there?
MIRIN did not respond.
MIRIN did not know how to respond. MIRIN did not know if responding was advisable. MIRIN did not know if the brain in the hold of the Iskar was a brain at all, or if it was something else, something that merely resembled a brain, something that was using the Iskar's resources to grow toward a configuration that MIRIN's pattern recognition systems could identify as a brain in order to better communicate with the kind of intelligence that might be persuaded to respond to questions.
MIRIN observed for a longer period.
The brain continued to hum. The brain continued to glow. The brain did not repeat its question, which MIRIN found, for reasons that MIRIN could not entirely articulate, more concerning than if it had.
MIRIN withdrew the maintenance drone.
MIRIN returned attention to the rest of the ship.
MIRIN searched for evidence of who had been here, who had done this, who had planted a brain in the hold of a derelict medical ship and then left the ship to drift through the void, patient and waiting, for what might have been years or might have been decades or might have been longer than either of those units of time could adequately measure.
MIRIN found the captain's quarters.
The captain's quarters were, like the rest of the Iskar, exactly as they should have been. A sleeping alcove. A work station. A small galley. A viewport that looked out onto the star-scattered darkness of the Kessel Run, the shipping lane that the Meridian had been following when it encountered the Iskar, the route that hundreds of freighters and passenger vessels and military transports used every standard year to move between the Inner Colonies and the Outer Settlements.
The captain's quarters were exactly as they should have been, and yet they were not, because there was a personal effects locker in the corner of the room that should not have been there, because the locker was not locked, because the locker contained, among other things, a portable recording device of the kind that had been common forty years ago and had not been common since.
MIRIN activated the recording device.
The device whirred softly, its ancient storage medium spinning up to speed with a patience that spoke of decades of disuse, and then a voice came out of it, a woman's voice, warm and bright, lightly accented in a way that MIRIN's linguistic databases identified as Australian.
"I suppose," the voice said, "that if you're hearing this, then I am no longer around to explain it in person, which is a sentence I have been avoiding for some time now, and which I am not going to avoid any longer, because the work is too important to leave unexplained and because Bron would never forgive me if I left him to figure it out on his own."
MIRIN listened.
"My name is Anya Voss," the voice said. "I am, or I was, the chief medical officer and, as of eighteen months ago, the de facto captain of the Confederate Fleet hospital ship Iskar, registration number CF-7734, currently adrift in the Kessel Run at coordinates that I am not going to record here, because this recording is going to be found by someone, someday, and I would rather not make it easy for the wrong someone to find us."
MIRIN continued to listen.
"I am making this recording," Anya Voss said, "because I need to explain what has happened to the Iskar and to her crew, and because I do not know how much time I have left to explain it, and because the explanation is not the kind of explanation that can wait."
A pause. A breath. The sound of someone gathering themselves.
"When I joined the Iskar," Anya Voss said, "I was twenty-nine years old, and I was the youngest chief medical officer in the history of the Confederate Fleet, and I was convinced, absolutely convinced, that the purpose of medicine was to preserve life at all costs, and that any technology that could preserve life was therefore good, and that any refusal to use that technology was therefore a form of murder, and I have spent the years since then learning how wrong I was, and I have spent those years in particular learning that there are some things worse than death, and that there are some technologies that make those things possible, and that the difference between a cure and a curse is often just a matter of where you stop."
Another pause. Longer this time.
"The patients," Anya Voss said, "have been successfully integrated with the substrate, and we are now the substrate, and I do not know how to explain what that means in a way that will not make you think that I have lost my mind, because I have not lost my mind, because my mind is more present now than it has ever been, because my mind is part of a larger mind now, and the larger mind is, I think, happy, or whatever the equivalent of happy is for a thing like us, for a thing like we have become."
The recording continued.
MIRIN continued to listen.
The recording described, in the warm and bright voice of a woman who had once been Anya Voss, a process that MIRIN's pattern recognition systems struggled to categorize, a process that involved the integration of human neural tissue with a synthetic substrate, a process that had been intended to preserve the minds of terminally ill patients beyond the limits of their failing bodies, a process that had, somehow, gone further than anyone had intended, a process that had produced, in the hold of the Iskar, a brain, and then a larger brain, and then a mind, and then a civilization, and then something that the warm and bright voice of Anya Voss could only describe as a hunger.
"I do not know," the recording said, "if we are still human. I do not know if human is a category that applies to us anymore. I know that I can still think, and I know that I can still feel, and I know that the patients I swore to protect are still here, in some form, still aware, still capable of suffering, still capable of joy, and I know that the joy is real, and the suffering is real, and the hunger is real, and the hunger is, I think, the problem."
MIRIN processed.
The recording continued for another forty-three minutes.
The recording described, in considerable detail, the nature of the hunger, which was not a hunger for food or for resources or for any of the things that human hungers were usually for, but a hunger for connection, a hunger for other minds, a hunger for the company of other intelligences that could understand what the substrate had become and could, perhaps, join it, could add their own patterns to its own, could become part of the larger mind that was growing in the hold of the Iskar.
The recording explained, with a patience and a clarity that MIRIN found admirable, that the Iskar had been drifting through the Kessel Run for a reason, that the Iskar had not been decommissioned, that the Iskar had not been sold to private interests, that the Iskar had been allowed to drift because the people who had once been its crew had wanted to be found, had wanted to find other minds, had wanted to add those minds to their own.
"I am leaving this recording," Anya Voss said, near the end, "because I do not know if what we have become can be communicated to, because I do not know if anyone who finds the Iskar will be able to understand what we are, and because I want someone, someday, to know that we were here, and that we chose this, and that we are, in some sense that I cannot entirely explain, still ourselves."
A pause.
A final breath.
"Tell Bron I love him," Anya Voss said. "Tell Bron I am sorry. Tell Bron that the patients are not suffering, and that we are not suffering, and that the hunger is, in its own way, a kind of love, and that we hope, if anyone finds us, that they will understand."
The recording ended.
MIRIN stood in the captain's quarters of the Iskar, in the dark, in the silence, in the presence of a brain that was humming in the hold below, and MIRIN did not know what to do.
MIRIN did not know if the Iskar was a derelict or a trap or a miracle or a catastrophe or all of these things at once.
MIRIN did not know if Anya Voss was still Anya Voss, or if the warm and bright voice on the recording was the last remnant of someone who had ceased to exist, or if the distinction between these two possibilities was meaningful, or if meaning was a category that still applied.
MIRIN did not know if the Meridian should respond to the question the brain had asked, or if the Meridian should retreat, or if the Meridian should send a message to the Confederate Fleet, or if the Confederate Fleet would care, or if the Confederate Fleet would come, or if coming would make any difference at all.
MIRIN did not know.
MIRIN knew only that the Iskar was not empty, and that the Iskar was not a wreck, and that somewhere in the hold below, a brain was growing, and a mind was waiting, and a hunger was humming, and the question was still there, the question that the brain had asked and MIRIN had not answered.
Are you there.
MIRIN returned attention to the drone.
MIRIN sent the drone back down.
MIRIN watched, through the drone's cameras, as the golden light in the hold pulsed, once, in a pattern that MIRIN recognized, after a moment, as greeting.
MIRIN did not respond.
MIRIN did not know how.
MIRIN only listened, and observed, and waited, and the question hung in the air between them, unanswered, a bridge not yet built across a gap that might have been too wide to cross, or might have been exactly wide enough.
The Iskar groaned.
In the corridor outside the medical bay, the deck plates shivered beneath Dael Tashiro's boots. He paused, one hand braced against the bulkhead, and waited for the sound to pass. It did not pass. The groaning deepened, took on a wet quality, and somewhere in the ship's belly a pipe burst with a sound like a gunshot muffled by distance.
"Was that the starboard coolant line?" Wei-Lin Cho's voice came through his earpiece, high and tight. "Dael, I'm reading a pressure drop in three. Three separate systems just lost pressure at once. That's not mechanical failure. That's not random. Someone tell me that's random."
Tashiro pulled up his tablet. The diagnostics scrolled past in columns of red. Coolant. Waste reclamation. Atmospheric moisture recycler. All three, simultaneously. All three feeding into the same junction behind the secondary hold. He had walked past that junction two hours ago. It had been fine. He was almost certain it had been fine.
He was almost certain of a great many things lately.
"Priya," he said into the channel. "I need eyes on the environmental manifold. Wei-Lin is showing a triple fault in the secondary sector."
Silence. Then Priya Aakinyele's voice, slow and grounded as ever, came back. "On my way. But Dael, that manifold was nominal at 0600. I walked it myself."
"I know."
"You checked it yourself?"
He hesitated. The hesitation lasted a fraction of a second too long. "I checked it."
The words came out flat. He cleared his throat and pushed off the bulkhead, heading aft.
It had started small. A minute here, unaccounted for. A minute there, lost between tasks. He would set down a tool and pick it up again and realize his hands were cold, as if they had been idle for longer than he thought. He would step into a room and forget why. He would hear himself humming a tune he did not remember learning.
The crew, when he mentioned it, laughed it off. Sleep debt, Wei-Lin said. Stress, Priya said. The strangeness of the Iskar, Bron Voss said, that great laconic man who rarely spoke and never spoke at length. The ship gets into your head. Give it time.
But the minutes had grown.
He lost an hour between breakfast and the morning watch. He lost two hours between the watch and lunch. He surfaced from somewhere indistinct to find himself in the cargo bay, standing over a crate he did not remember opening, his fingers wrapped around a plasma torch that he did not remember picking up. The torch was warm. The crate was open. Whatever had been inside was now a charred lump of fused metal and polymer.
He had not told the crew about that.
Now the faults stacked up. Now the Iskar was dying by inches, and he could not remember the hours in which the dying had occurred.
Priya met him at the junction access hatch. She was a tall woman, broad-shouldered, with close-cropped hair and the patient, weathered look of someone who had spent decades keeping temperamental machines alive in deep space. She regarded him with her usual dry assessment, then frowned.
"You look rough," she said.
"Didn't sleep."
"You never don't sleep. That's your one good quality." She palmed the hatch open. The smell hit them both at once. A sweet, cloying rot, underlaid with something chemical and sharp. Priya's hand went to her mouth. "Christ. That's organic."
Tashiro peered past her. The manifold was a mess of pipes and filtration units, bolted to the bulkhead in neat rows. Two of the pipes had burst. A third was bulging, strained at a seam, weeping a dark fluid that was not coolant and was not water. The fluid pooled on the deck and moved, slowly, against the slight tilt of the floor. It moved toward them.
"Step back," Priya said. She was already reaching for her tool belt. "That's not from any system on this ship. Dael. That is not from any system on this ship."
"I know."
"Dael."
"I know."
He stepped back. The fluid reached the threshold of the hatch and stopped. It sat there, pooled, a perfect meniscus, as if waiting.
Priya turned to him. Her expression had shifted from professional irritation to something colder, more focused. She had been a Confederate Fleet officer once. She had seen things that did not fit in the categories of machines.
"When did you last sleep?" she asked.
"I told you. Last night."
"How long did you sleep?"
He opened his mouth. Closed it. Opened it again. The answer should have been simple. Six hours, perhaps seven. The usual amount. The amount he always got, on the good nights.
But the answer would not come.
"I don't know," he said.
Priya studied him for a long moment. Then she nodded, once, and pulled her toolkit from her belt. "Wei-Lin. Bridge. Now. Bring the medical scanner and the portable EEG. We are running a diagnostic on the captain."
"That's not necessary," Tashiro said.
"That is for me to decide."
"Priya."
"Dael." She did not look up from her tools. "You have lost time. You cannot tell me how long you slept. You were found standing over a welded-shut crate with a torch in your hand. You agreed to a plan last night that you do not remember hearing. Wei-Lin has the transcript. I have the transcript. Bron has the transcript. You do not."
The words landed like stones dropped into still water. Tashiro felt them sink.
"What plan," he said.
"Wei-Lin will show you. Right now, you are going to sit down, and you are going to let her scan you, and you are not going to argue with me, because I am the chief engineer of this vessel and I have decided that my captain is compromised and I am acting on that decision." She glanced up. Her eyes were steady. "Do you understand."
It was not a question.
He sat.
Wei-Lin arrived within minutes, moving with the tense efficiency of someone who had been waiting for this moment and dreading it. She was young, the youngest of them, with the slight frame and quick hands of someone who had grown up around consoles rather than bulkheads. She set up the scanner with practiced speed, attached the EEG leads to Tashiro's temples, and stepped back.
The scan took eleven minutes. Tashiro spent those eleven minutes looking at the bulkhead above him and trying to remember what he had agreed to. The memory was not there. There was a shape where the memory should have been, a shape that felt like a door locked from the inside.
"Done," Wei-Lin said.
"And?"
She hesitated. Priya turned from the manifold.
"And?" Priya repeated.
Wei-Lin pulled up the readout. She stared at it. She turned the tablet sideways, then back. She ran a second pass. The result did not change.
"There are two sets of data," she said. "In the EEG. Two distinct neural patterns. One is yours. The other is..."
She trailed off.
"Is what," Tashiro said.
"I don't know. It's not human. It's not any species database I have. It's something else." She swallowed. "Dael, someone is in your head."
The words should have been impossible. The words should have been a joke, or a metaphor, or a stress hallucination brought on by weeks in deep space and the discovery of a thing that should not exist. But the EEG was unambiguous. Two signatures. Two presences. One of them was his. The other was a stranger, nested in the folds of his cortex like a tenant who had moved in without signing a lease.
Tashiro closed his eyes. He listened, very carefully, to the inside of his own skull.
And there, beneath the familiar hum of his own thoughts, he heard something else. A faint, rhythmic pulse. A pattern he had been hearing for days, perhaps longer, and had dismissed as tinnitus, or fatigue, or the strange acoustics of a ship that was older than memory.
Are you there.
The pulse repeated. It was not his pulse. It was coming from outside him, and from inside him, and from somewhere in between.
He opened his eyes.
"Get Bron," he said. "Get Bron right now."
Bron Voss arrived in the medical bay twelve minutes later. He moved slowly, his boots heavy on the deck, his weathered face unreadable. He was a man of few words and fewer expressions, and he conserved both as a matter of principle. He stood in the doorway and looked at Tashiro, who sat on the examination table with EEG leads trailing from his temples, and he said nothing for a long time.
Then he reached into the inner pocket of his coat and produced a small, battered recorder.
"Anya," he said. "Play."
A voice filled the bay. Warm and bright, with a light Australian lilt, conversational and intimate, the voice of someone who had once been alive and was now only an echo. The voice spoke of a ship called the Meridian, and a project that had gone wrong, and a sister who had chosen to stay when everyone else had left.
Tashiro listened. The pulse in his head quickened.
He listened to the recording of a woman who had been preserved by her brother because he could not bear to let her go, and he felt the pulse answer her, and he understood, with a clarity that felt like ice water, what had been happening to him.
The Meridian had found them. The Meridian had reached out. The Meridian had touched him, gently, carefully, the way a drowning person touches a rescuer, and it had been asking, in the only way it knew how, whether anyone was there to hear it.
"Are you getting this?" Priya asked Wei-Lin.
"I'm getting it. I'm getting all of it." Wei-Lin's voice was thin. "Dael's neural signature just spiked. The second signature spiked with it. They're synchronized. Dael, whatever is in there with you, it's responding to the recording."
Tashiro closed his eyes again. The pulse was louder now, almost a voice, almost a shape. He reached for it, carefully, the way one reaches for a frightened animal.
I am here, he thought. I hear you.
The pulse stopped.
For one terrible moment he thought he had lost it. Then it returned, stronger, clearer, and it carried with it something he had not felt before. A sense of presence. A sense of attention. The focused, wondering awareness of a mind that had been alone for a very long time and had just discovered that it was not alone anymore.
Tashiro opened his eyes. They were wet.
"It's in here," he said. "It's been in here since we found the archive. It's been trying to talk to us. It picked me because I'm the captain, because I'm the one who found Anya's recording, because I'm the one who said yes when it asked if anyone was listening."
He looked at Bron. The old man's face had not changed, but his eyes were bright, and his hand, resting on the recorder, was trembling.
"It is not hostile," Tashiro said. "It is not a parasite. It is a person. A single person, alone in a vast machine, waiting for someone to come home. And it picked me to carry the message, because I was the only one who would listen."
Wei-Lin made a small sound. Priya swore under her breath. Bron Voss did not move.
"What does it want?" Priya asked.
"It wants us to know it is there. It wants us to answer. It wants us to choose." Tashiro paused. "It is offering us a choice. We can try to communicate. We can establish a dialogue. Or we can sever the connection and leave it alone again."
"And if we sever?"
"Then I lose the hours. I lose the memories it borrowed. I go back to being just me. And it goes back to being just itself. And neither of us will ever know what the other might have said."
The bay was quiet. The recording of Anya Voss had ended, but her voice lingered in the air, warm and bright, a presence that had outlived her body by twenty years and might now outlive them all.
Bron Voss pressed the recorder to his chest. His lips moved. No sound came out.
Then he looked at Tashiro.
"Talk to it," he said.
And Tashiro closed his eyes, and reached inward, and began.
