The Best Science Fiction & Fantasy of the Year. Volume 5

The hull was gray and smooth, gray and empty, and in every direction it fell away gradually, vanishing where the cold black of the sky pretended to touch what was real. What was real was the Great Ship. Nothing else enjoyed substance or true value. Nothing else in Creation could be felt, much less understood. The Ship was a sphere of perfect hyperfiber, world-sized and enduring, while the sky was only a boundless vacuum punctuated with lost stars and the occasional swirls of distant galaxies. Radio whispers could be heard, too distorted and far too faint to resolve, and neutrino rains fell from above and rose from below, and there were ripples of gravity and furious nuclei generated by distant catastrophes—inconsequential powers washing across the unyielding, eternal hull.

Do not trust the sky, the walker understood. The sky wished only to tell lies. And perhaps worse, the sky could distract the senses and mind from what genuinely mattered. The walker’s only purpose was to slowly, carefully move across the Ship’s hull, and if something of interest were discovered, a cautious investigation would commence. But only if it was harmless could the mystery be approached and studied in detail. Instinct guided the walker, and for as long as it could remember, the guiding instinct was fear. Fierce, unnamed hazards were lurking. The walker could not see or define its enemies, but they were near, waiting for weakness. Waiting for sloth or inattentiveness. Regardless how curious it was or how fascinating some object might be, the walker scrupulously avoided anything that moved or spoke, or any device that glowed with unusual heat, and even the tiniest example of organic life was something to be avoided, without fail.

Solitude was its natural way.

Alone, the ancient fear would diminish to a bearable ache, and something like happiness was possible.

Walking, walking. That was the purpose of existence. Select a worthy line, perhaps using one of the scarce stars as a navigational tool. Follow that line until something new was discovered, and regardless whether the object was studied or circumvented, the walker would then pick a fresh direction—a random direction—and maintain that new line with the same tenacity.

There was no need to eat, no requirement for drink or sleep. Its life force was a minor, unsolvable mystery. The pace was patient, every moment feeling long and busy. But if nothing of note occurred, nothing needed to be recalled. After a century of uninterrupted routine, the walker compressed that blissful sameness into a single impression that was squeezed flush against every other vacuous memory—the recollections of a soul that felt ageless but was still very close to empty.

Eyes shrank and new eyes grew, changing talents. With that powerful, piercing vision, the walker watched ahead and beside and behind. Nothing was missed. And sometimes for no obvious reason it would stop, compelled suddenly to lower several eyes, staring into a random portion of the hull. From the grayness, microscopic details emerged. Fresh radiation tracks still unhealed; faint scars being gradually erased by quantum bonds fighting to repair themselves. Each observation revealed quite a lot about the hyperfiber, and the lessons never changed. The hull was a wonder. Fashioned from an extremely strong and lasting material—a silvery-gray substance refined during a lost age by some powerful species, perhaps, or perhaps a league of vanished gods. They were the masters who must have imagined and built the Ship, and presumably the same wondrous hands had sent their prize racing through the vacuum. A good, glorious purpose must be at work here; but except for the relentless perfection of the Great Ship, nothing remained of their intentions, their goals, or even an obvious destination.

When the walker kneeled, the hull’s beauty was revealed.

And then it would stand again and resume its slow travels, feeling blessed to move free upon this magnificent face.

There was no purpose but to wander the perfection forever: that was an assumption made early and embraced as a faith. But as the centuries passed, oddities and little mysteries gradually grew more numerous. Every decade brought a few more crushed steel boxes and empty diamond buckets than the decade before, and there were lumps of mangled aerogel, and later, the occasional shard of some lesser form of hyperfiber. As time passed, the walker began to come across dead machines and pieces of machinery and tools too massive or far too ordinary to be carried any farther once they had failed. These objects were considerably younger than the Ship. Who abandoned them was a looming mystery, but one that would not be solved soon. The walker had no intention of approaching these others. And in those rare times when they approached it—always by mistake, always unaware of its presence—it would flatten itself against the hull and make itself vanish.

Invisibility was a critical talent. But invisibility meant that it had to abandon most of its senses. Even as they strode across its smooth back, these interlopers were reduced to a vibration with each footfall and a weak tangle of magnetic and electrical fields.

Days later and safe again, the walker would rise up carefully and move on.

Another millennium passed without serious incident. It was easy to believe that the Great Ship would never change, and nothing would ever be truly new; and holding that belief close, the walker followed one new line. No buckets or diamond chisels were waiting to change its direction. As it strode on, the stars and sky-whispers silently warned that it was finally passing into unknown territory. But this did happen on occasion. Perfection meant sameness, and the walker could imagine nothing new. Then what seemed to be a flat-topped mountain began to rise over the coming horizon. Puzzled, it made note of the sharp gray line hovering just above the hull. More years of steady marching caused the grayness to lift higher, just slightly. Perhaps a mountain of trash had been set there. Perhaps a single enormous bucket upended. Various explanations offered themselves; none satisfied. But the event was so surprising, enormous and unwelcome, and the novelty so great, that the walker stopped as soon as it was sure that something was indeed there, and without taking one step, it waited for three years and a little longer, adapting its eyes constantly, absorbing a view that refused to change.

Finally, curiosity defeated every caution, and altering its direction, the walker steered straight toward what still made no sense.

At a pace that required little energy, it pressed ahead in half-meter strides. Decades passed before it finally accepted what was obvious: that while the Ship was undoubtedly perfect, it was by no measure perfectly smooth and eternally round. Rising from the hull was not one gigantic tower, but several. The nearest tower was blackish-gray and too vast to measure from a single perspective. Occasionally a small light appeared on the summit, or several tiny flecks of light danced beside its enormous bulk, and there were sudden spikes in dense, narrow radio noise that tasted like a language. Various explanations occurred to the walker. From where these possibilities came, it could not say. Maybe they arose from the instincts responsible for its persistent fears. But like never before, it was curious. It started to move once again, slowly and tirelessly pushing closer, and that was when it noticed how one of the more distant towers had begun to tip, looking as if it was ready to collapse on its side. And shortly after that remarkable change in posture, the tower suddenly let loose a deep rumble, followed by a scorching, sky-piercing fire.

But of course: these were the Ship’s engines. No other explanation was necessary, and in another moment, the walker absorbed its new knowledge, a fresh set of beliefs gathering happily around the Ship’s continued perfection. Fusion boosted by antimatter threw a column of radiant blue-white plasmas into the blackness, scorching the vacuum. This was a vision worth admiration. Here was power beyond anything that the walker had ever conceived of. But soon the engine fell back into sleep, and after thorough reflection, it decided to choose another random direction, and another, selecting them until it was steering away from the gigantic rocket nozzles.

If objects this vast had missed its scrutiny, what else was hiding beyond the horizon?

Walk, walk, walk.

But its pace began to slow even more. Flying vessels and many busy machines were suddenly common near the engines, and some kind of animal was building cities of bubbled glass. An invasion was underway. There were regions of intense activity and considerable radio noise, and each hazard had to be avoided, or if the situation demanded, crossed without revealing its presence.

Ages passed before the engines vanished beyond the horizon. A bright red star became the walker’s beacon, its guide, and it followed that rich light until the ancient sun sickened and went nova, flinging portions of its flawed skin out into the cooling, dying vacuum.

Younger stars appeared, climbing from the horizon as the walker pressed forward. A second sky was always hiding behind the hyperfiber body. The walker felt the play of gravity and then the hard twisting, the Ship leaving the line that had been followed without interruption for untold billions of years. After that, the sky was changed. The vacuum was not nearly so empty, or quite as chilled, and even a patient entity with nothing to do but count points of light could not estimate just how many stars were rising into its spellbound gaze.

A galaxy was approaching. One great plate of three hundred billion suns and trillions of worlds was about to intersect with a vessel that had wandered across the universe, every previous nudge and great reaches of nothingness leading to this place and this rich, perfect moment.

And here the walker stood, on the brink of something entirely new.

There was a line upon the hull that perhaps no one else could have noticed. Not just with their eyes and the sketchy knowledge available, no. But the walker recognized the boundary where the hull that it knew surrendered to another. Suddenly the thick perfect hyperfiber was replaced with a thicker but considerably more weathered version of faultless self. Even in the emptiest reaches of the universe, ice and dust and other nameless detritus wandered in the dark.

These tiny worlds would crash down on the Ship’s hull, always at a substantial fraction of light-speed, and not even the best hyperfiber could shrug aside that kind of withering power. Stepping onto the Ship’s leading face, the walker immediately noticed gouges and debris fields and then the little craters that were eventually obscured by still larger craters—holes reaching deep into the hard resilient hull. Most of the wounds were ancient, although hyperfiber hid its age well. All but the largest craters were unimportant to the Ship’s structure, their cumulative damage barely diminishing its abiding strength. But some of the wounds showed signs of repair and reconditioning. The walker discovered one wide lake of liquid hyperfiber, the patch still curing when it arrived on the smooth shoreline. Kneeling down, it looked deep into the still-reflective surface. For the first time in memory, there was another waiting to be seen. But the entity felt little interest in its own appearance. What mattered was the inescapable fact that someone—some agent or benevolent hand—was striving to repair what billions of years of abuse had achieved. A constructive force was at work upon the Ship. A healing force, seemingly. Enthralled, the walker looked at the young lake and the reflected Milky Way, measuring the patch’s dimensions. Then it examined the half-cured skin, first with fresh eyes and then with a few respectful touches. A fine grade of hyperfiber was being used, almost equal to the original hull.Which implied that caretakers were striving to do what was good and make certain that their goodness would endure.

The endless wandering continued.

Eventually the galaxy was overhead, majestic but still inconsequential. The suns and invisible worlds were little more than warm dust flung across the emptiness, and still all that mattered was the Ship, dense and rich beyond all measure. Walk, and walk. And walk. And then it found itself on the edge of another crater—the largest scar yet on the hull—and for the first time ever, it followed a curving line, the crater’s frozen lip defining its path.

Bodies and machines were working deep inside the ancient gouge.

From unseen perches, it watched the activity, studying methods and guessing reasons when it could not understand. The vacuum crackled with radio noise. The sense of words began to emerge, and because the skill might prove useful, the walker committed to memory what it understood of the new language. Hundreds of animals worked inside the crater—humans they called themselves, dressed inside human-shaped machines. And accompanying them were tens of thousands of pure machines, while on the lip stood a complex of prefabricated factories and fusion reactors and more humans and more robots dedicated to no purpose but repairing one minuscule portion of the Ship’s forward face.

As it kneeled there, unseen, a bit of cosmic dirt fell with a brilliant flash of light, leaving a tiny crater inside the giant one.

The danger was evident, but there were blessings too. The walker slipped across a narrow track lain on the unbroken hull, presumably leading from some far place to the crater’s edge. The track was a superconductive rail that allowed heavy tanks to be dragged here, each tank filled with uncured, still-liquid hyperfiber. From another hiding place, the walker watched as a long train of tanks arrived and subsequently drained before being set on a parallel track and sent away. Before the third was empty, it understood enough to appreciate just how difficult this work was. Liquid hyperfiber was fickle, eager to form lasting bonds but susceptible to flaws and catastrophic embellishments. Down in the crater, a brigade of artisans was struggling to repair the damage—a tiny pock on the vast bow of the Ship—and their deed, epic as well as tiny, was ringing testament to the astonishing gifts of those who had first built the Great Ship.

All but one of the empty tanks was sent home. The exception was damaged in a collision and then pushed aside, abandoned. Curious about that silver tank, the walker approached and then paused, crept closer and paused again, making certain that no traps were waiting, no eyes watching. Then it slipped near enough to touch the crumbled body. That innate talent for mechanical affairs was awakened again. Using thought and imaginary tools, it rebuilt the empty vessel. Presumably those repairs were waiting for a more convenient time. Unless the humans meant to leave their equipment behind, which was not an unthinkable prospect, judging by the trash already scattered about this increasingly crowded landscape.

One end of the tank was cracked open, the interior exposed. In slow, nearly invisible steps, the walker slipped inside. The cylinder was slightly less than a kilometer in length. Ignoring every danger, the walker passed through the ugly fissure, and once inside, it balanced on a surface designed to feel slick to every possible material. Yet it managed to hold its place, retaining its pose, peering into the darkness until it was sure that it was alone, and then it let light seep out of its own body, filling the long volume with a soft cobalt-blue glow.

Everywhere it looked, it saw itself looking back.

Reflected on the round wall were distorted images of what might be a machine, or perhaps was something else. Whatever it was, the walker had no choice but to stare at itself. This was indeed a trap, it realized, but instead of a secret door slamming shut, the mechanism worked by forcing an entity to gaze upon its own shape and its nature, perhaps for the first time.

What it beheld was not unlovely.

But how did it know beauty? What aesthetic standard was it employing? And why carry such a skill among its instincts and talents?

A long time passed before the walker could free itself from the trap. But even after it climbed back onto the open hull, escape proved difficult. It slinked away for a good distance and then stopped, and then it walked farther before turning back again. Where did this obligation come from, this need to stare at an empty, ruined tank? Why care about a soulless object that would never function again? How could that piece of ruin bother it so? And why, even after walking far enough to hide both the tank and the crater beyond the horizon…why did its mind insist on returning again and again to an object that others had casually and unnecessarily cast aside?

It walked. It counted steps. It had reached two million four hundred thousand and nine steps when humans suddenly appeared in their swift cars. The invaders settled within a hundred meters of the walker. With a storm of radio talk and the help of robots, they quickly erected a single unblinking eye and pointed it straight above. The walker hid where it happened to be, filling a tiny crater. Unnoticed, it lay motionless as the new telescope was built and tested and linked to the growing warning system.And then the humans left, but the walker remained inside its safe hole, sprouting an array of increasingly powerful eyes.

The sky might be untrustworthy, but there was beauty to the lie. The Great Ship was plunging into a galaxy that was increasingly brilliant and complex and dangerous. More grit and chunks of wayward ice slammed against the hull, and the bombardment would only strengthen as the Ship sliced into the thick curling limb of suns. But the humans were answering the dangers with increasingly powerful weapons. Telescopes watched for hazards. Then bolts of coherent light melted the incoming ices. Ballistic rounds pulverized asteroids. Sculpted EM fields slowed the tiniest fragments and shepherded them aside. There was splendor to that awful fight. Flashes and sparkles constantly surprised the lidless eyes. Ionized plasmas generated squawks and whistles reaching across the spectrum. An accidental music grew louder, urgent and carefree. No defensive system was unbreakable. Death threatened everything foolish enough to walk upon the bow. Each moment might be its last. But the scene deserved fascination and wonder. It stared upwards, and it grew antennae and listened, and its mind began to believe that this violent magic had a rhythm, an elegant inescapable logic, and that whatever note and whichever color came next could have been foreseen.

That was when the voice began.

At least that was the moment when the walker finally took notice of the soft, soft whispers.

These mutterings were not part of the sky. Intuition told the walker that much. Perhaps the voice rose from the hull, or maybe it came from the chill vacuum. But what mattered more than its origin was the quiet swift terror that defined its presence—an inarticulate, nearly inaudible murmur that came when it was unexpected and vanished before any response could be offered.

Following the first eleven incidents, the walker remained silently anxious.

But the twelfth whisper was too much. With a radio mouth formed for the occasion, and using the human language that it had learned over the last centuries, the walker called out, “What are you? What do you want?” And when nothing replied, it added, “Do not bother me. Leave me alone.”

By chance or by kindness, the request was honored.

The walker rose and again wandered across the bow. But after witnessing several jarring impacts, it returned to the stern, ready to accept the safety afforded by the Ship’s enormous bulk. But there were even more humans than before, and they brought endless traffic on what had been delicious, seemingly infinite emptiness. Following a twisting, secretive line, the walker journeyed to the nearest engine, and with some delight, it touched the mountainous nozzle at its base. But machines were everywhere, investigating and repairing, and the human chatter was busy and endless, jabbering about subjects and names and places and times that made no sense at all.

Where the bow and stern joined, starships were landing. The walker tracked them by their bright little rockets. Hunkering behind piles of trash, it watched the slow taxis and quicker streakships drop onto the hull, and then enormous doors would pull open, and the visitors would vanish. The walker had never seen a spaceport, never even imagined such a thing was possible. Once again, the Great Ship was far more than it pretended to be. Creeping even closer, it estimated the size of the incoming vessels. Considering how many passengers might be tucked inside each little ship, it was easy to understand why the hull had grown crowded. The human animals were falling from the sky, coming here for the honor of living inside their bubble cities on the hull of this lost, unknowable relic.

Finally, in slow patient stages, the walker crept to the edge of a vast door, and with a single glance, its foolishness was revealed. The Great Ship was more than its armored hull. What the entity had assumed to be hyperfiber to the core was otherwise. Inside the spaceport, it saw a vast column of air and light and warm wet bodies moving by every means and for no discernable purpose. This was motion, swift and busy and devoid of any clear purpose. Humans were just one species among a multitude, and beneath the hull, the Ship was pierced with tunnels and doorways and hatches and diamond-windows, and that was just what the briefest look provided before it flattened out and slowly, cautiously crawled away.

The Ship was hollow.

And judging by the evidence, it was inhabited by millions and maybe billions of organic entities.

These unwanted revelations left it shaken. Months were required to sneak away from the port. Unseen, it returned to the bow face and the beautiful sky, accepting the dangers for the illusion of solitude. But the ancient craters were being swiftly erased now. The Ship’s lasers were pummeling most of the cometary debris that dared pass nearby, and the repair crews were swift and efficient now. The pitted, cracked terrain was vanishing beneath smooth perfection. The new hyperfiber proved fresh and strong, affording few hiding places even for a wanderer who could hide nearly anywhere. By necessity, every motion was slow. Was studied. But even then, a nearby robot would notice a presence, and maybe EM hands would reach out, trying to touch what couldn’t be seen; and by reflex, the walker stopped living and stopped thinking, hiding away inside itself as it pretended to be nothing but another patch lost among the billions.

Eventually it came upon a freshly made crater, too small to bring humans immediately but large enough to let it walk down inside the wounded hull.

A brief, sharp ridge stood in its way—the relic of chaotic, billion-degree plasmas. After five hours of careful study, the walker slowly crossed the ridge. Humans never came alone to these places, and there was no sign of any machine. But standing on the ridgeline, urgency took hold. Something here was wrong. And what was wrong felt close. The walker began to lower itself, trying to vanish. But then a strong voice said, “There you are.”

It hunkered down quickly.

Then with amusement, someone said, “I see you.”

The voice—the mysterious and uninvited phenomena—was always quieter than this. It has always been a whisper, and far less comprehensible. Perhaps the young crater helped shape its words. Perhaps the bowl with its sharp refrozen hyperfiber lip lent strength and focus.

In myriad ways, the walker began to melt into the knife-like ridge.

Yet the voice only grew louder—a radio squawk wrapped around the human language. With some pleasure, she said, “You cannot hide from me.”

“Leave me be,” the walker answered.

“But you’re the one disturbing me, stranger.”

“And I have told you,” the walker insisted. “Before, I told you that I wish to be alone. I must be alone. Don’t pester me with your noise.”

“Oh,” the voice replied. “You believe we’ve met. Don’t you?”

Curiosity joined the fear. A new eye lifted just a little ways, scanning the closest few meters.

“But I’ve never spoken to you,” the voice continued. “You’ve made a mistake. I don’t know whose voice you’ve been hearing, but I’m rather certain that it wasn’t mine.”

“Who are you?” the walker asked.

“My name is Wune.”

“Where are you?”

“Find the blue-white star on the horizon,” she said.

It complied, asking, “Are you that star?”

“No, no.” Wune could do nothing but laugh for a few moments. “Look below it. Do you see me?”

Except for a few crevices and delicate wrinkles, the crater floor was flat. Standing at the far end was a tiny figure clad in hyperfiber. An arm lifted now. What might have been a hand waved slowly, the gesture purely human.

“My name is Wune,” the stranger repeated.

“Are you human?” the entity whispered nervously.

“I’m a Remora,” said Wune. Then she asked, “What exactly are you, my friend? Since I don’t seem to recognize your nature.”

“My nature is a mystery,” it agreed.

“Do you have a name?”

“I am,” it began. Then it hesitated, considering this wholly original question. And with sudden conviction, it said, “Alone.” It rose up from the ridge, proclaiming, “My name is Alone.”

“Come closer, Alone.”

It did nothing.

“I won’t hurt you,” Wune promised, the arm beckoning again. “We should study each at a neighborly distance. Don’t you agree?”

“We are close enough,” the walker warned, nearly two kilometers of vacuum and blasted hyperfiber separating them.

The Remora considered his response. Then with an amiable tone, she agreed, “This is better than being invisible to one another. I’ll grant you that.”

For a long while, neither spoke.

Then Wune asked, “How good are those eyes? What do you see of me?”

Alone stared only at the stranger, each new eye focused on the lifesuit made of hyperfiber and the thick diamond faceplate and what lay beyond. Alone had seen enough humans to understand their construction, their traditions. But what was human about this face was misplaced. The eyes were beneath the mouth and tilted on their sides. The creature’s flesh was slick and cold in appearance, and it was vivid purple. The long hair on the scalp was white with a hint of blue, rather like the brightest stars, and that white hair began to lift and fall, twirl and straighten, as if an invisible hand was playing with it.

“I don’t know your species,” Alone confessed.

“But I think you do,” Wune corrected. “I’m a human animal, and a Remora too.”

“You are different from the others.”

“What others?” she inquired.

“The few that I have seen.”

“You spied on us inside the big crater. Didn’t you?” The mouth smiled, exposing matching rows of perfect human teeth. “Oh yes, you were noticed. I know that you strolled up to that busted tank and climbed inside before walking away again.”

“You saw me?”

“Not then, but later,” she explained. “A security AI was riding the tank. It was set at minimal power, barely alive. Which probably kept you from noticing it. We didn’t learn about you until weeks later, when we stripped the tank for salvage and the AI woke up.”

Shame took hold. How could it have been so careless?

“I know five other occasions when you were noticed,” Wune continued. “There have probably been more incidents. I try to hear everything, but that’s never possible. Is it?” Then she described each sighting, identifying the place and time when these moments of incompetence occurred.

“I wasn’t aware that I was seen,” it stated.

Ignorance made its failures feel even worse.

“You were barely seen,” Wune corrected.“ A ghost, a phantom. Not real enough to be taken seriously.”

“You mentioned a spaceport,” it said.

“I did.”

“Where is this port?”

Wune pointed with authority, offering a precise distance.

“I don’t remember being there,” Alone admitted.

“Maybe we made a mistake,” she allowed.

“But I did visit a different port.” With care, it sifted through its memories. “I might have troubles with my memory,” it confessed.

“Why do you think that?”

“Because I know so little about myself,” confessed the walker.

“That is sad,” Wune said. “I’m sorry for you.”

“Why?”

“Life is the past,” she stated. “The present moment is too narrow to slice and will be lost with the next instant.And the future is nothing but empty conjecture. Where you have been is what matters. What you have done is what counts for and against you on the tallies.”

The walker concentrated on those unexpected words.

“I have a telescope with me,” Wune said. “I used it when I first saw you. But I’m trying to be polite. If you don’t mind, may I study you now?”

“If you wish,” it said uneasily.

The Remora warned, “This might take some time, friend.” Then with both gloved hands, she held a long tube to her face.

Alone waited.

An hour later, Wune asked, “Are you a machine?”

“I don’t know. Perhaps I am.”

“Or do you carry an organic component inside that body?”

“Each answer is possible, I think.”

Wune lowered the telescope. “I’m a little of both,” she allowed. “I like to believe that I’m more organic than mechanical, but the two facets happily live inside me.”

Alone said nothing.

The Remora laughed softly, admitting, “This is fun.”

Was it?

To her new friend, she explained, “Thousands of years ago, humans learned how to never grow old. No disease, and no easy way to kill us.” The hands were encased in hyperfiber gloves. One of those fingers tapped hard against her diamond faceplate. “My mind? It’s a bioceramic machine. Which makes it tough and quick to heal and full of redundancies. My memories are safe inside the artificial neurons. Whenever I want, I can remember yesterday. Or I can pull my head back five centuries and one yesterday. My life is an enormous, deeply personal epic that I am free to enjoy whenever I wish.”

“I am different than you,” Alone conceded.

Wune asked, “Do you sleep?”

“Never.”

“Yet you never feel mentally tired?” The purple face nodded, and she said, “Right now, I’m envious.”

Envy was a new word.

“I’m trying to tell you something,” she said. “This old Remora lady has been awake for a very long time, and she needs to sleep for a little while. Is that all right? Do whatever you want while my eyes are closed. If you need, walk away from me. Vanish completely.” Then she smiled, adding, “Or you might take a step or two in my direction. If you feel the urge, that is.”

Then Wune shut her misplaced eyes.

During the next hour, Alone crept ahead a little more than three meters.

As soon as she woke, Wune noticed. “Good. Very good.”

“Are you rested now?”

“Hardly. But I’ll push through the misery.” Her laugh had a different tone. “What’s your earliest, oldest memory? Tell me.”

“Walking.”

“Walking where?”

“Crossing the Ship’s hull.”

“Who brought you to the Ship?”

“I have always been here.”

She considered those words. “Or you could have been built here,” she suggested. “Assembled from a kit, perhaps. You don’t remember a crowd of engineers sticking their hands inside you?”

“I remember no one.” Then again, with confidence, Alone claimed, “I have never been anywhere but on the Great Ship.”

“If that was true,” Wune began. Then she fell silent.

Alone asked, “What if that is so?”

“I can’t even guess at all of the ramifications,” she admitted. Then after a few minutes of silence, she said, “Ask something of me. Please.”

“Why are you here, Wune?”

“Because I’m a Remora,” she offered. “Remoras are humans who got pushed up on the hull to do important, dangerous work. There are reasons for this. Good causes, and bad justifications. Everything that you see here…well, the hull is not intended to be a prison. The captains claim that it isn’t. But now and again, it feels like an awful prison.”

Then she hesitated, thinking carefully before saying, “I don’t think that was your question. Was it?”

“Like me, you are alone,” it pointed out. “Most of the humans, Remoras and engineers and the captains…these humans usually gather in large groups, and they act pleased to be that way…”

With a serious tone, she said, “I’m rather different, it seems.”

Alone waited.

“The hull is constantly washed with radiation, particularly out here on the leading face.” She gestured at the galaxy. “My flesh is immortal. I can endure almost any abuse. But these wild nuclei crash through my cells, wreaking terrible damage. My repair mechanisms are always awake, always busy. I have armies of tiny workers marching inside me, trying to lift my flesh back to robust health. But when I’m alone, and when I focus on my body’s functions, I can influence my regenerating flesh. In some ways, with just willpower, I can direct my own evolution.”

That seemed to explain the odd, not quite human face.

“I’m out here teaching myself these tricks,” Wune admitted. “The hull is no prison. To me, it is a church. A temple. A rare opportunity for the tiniest soul to unleash potentials that her old epic life never revealed to her.”

“I understand each of your words,” said Alone.

“But?”

“I cannot decipher what you mean.”

“Of course you can’t.” Wune laughed. “Listen. My entire creed boils down to this: If I can write with my flesh, then I can write upon my soul.”

“Your ‘soul’?”

“My mind. My essence. Whatever it is that the universe sees when it looks hard at peculiar little Wune.”

“Your soul,” the walker said once again.

Wune spoke for a long while, trying to explain her young faith. Then her voice turned raw and sloppy, and after drinking broth produced by her recyke system, she slept again. The legs of her lifesuit were locked in place. Nearly five hours passed with her standing upright, unaware of her surroundings. When she woke again, barely twenty meters of vacuum and hard radiation separated them.

She didn’t act surprised. With a quieter, more intimate voice, she asked, “What fuels you? Is there some kind of reactor inside you? Or do you steal your power from us somehow?”

“I don’t remember stealing.”

“Ah, the thief’s standard reply.” She chuckled. “Let’s assume you’re a machine. You have to be alien-built. I’ve never seen or even heard rumors about any device like you. Not from the human shops, I haven’t.” After a long stare, she asked, “Are you male?”

“I don’t know.”

“I’m going to call you male. Does that offend you?”

“No.”

“Then perhaps you are.” She wanted to come closer. One boot lifted, seemingly of its own volition, and then she forced herself to set it back down on the hull.

“You claim not to know your own purpose. Your job, your nature. All questions without answer.”

“I am a mystery to myself.”

“Which is an enormous gift, isn’t it? By that, I mean that if you don’t know what to do with your life, then you’re free to do anything you wish.” Her face was changing color, the purple skin giving way to streaks of gold. And during her sleep, her eyes had grown rounder and deeply blue. “You don’t seem dangerous. And you do require solitude. I can accept all of that. But as time passes, I think you’ll discover that it’s harder to escape notice out here on the hull. The surface area is enormous, yes. But where will you hide? I promise, I won’t chase after you. And I can keep my people respectful of your privacy. At least I hope I can. But the Great Ship is cursed with quite a few captains, and they don’t approve of mysteries. And we can’t count all the adventurers who are coming here now, racing up from countless worlds. Maybe you don’t realize this, but our captains have decided to take us on a tour of the galaxy. Humans and aliens are invited, for a fat price, and some of them will hear the rumors about you. Some of these passengers will come up on the hull, armed with sensors and their lousy judgment.”

Alone listened carefully.

“My reasons are selfish,” Wune admitted. “I don’t want these tourists under my boots. And since you can’t hide forever in plain sight, we need to find you a new home.”

Horrified, he asked, “Where can I go?”

“Almost anywhere,”Wune assured. “The Great Ship is ridiculously big. It might take hundreds of thousands of years just to fill up its empty places. The caverns, the little tunnels. The nameless seas and canyons and all the dead-end holes.”

“But how can I find those places?”

“I know ways. I’ll help you.”

Terror and hope lay balanced on the walker’s soul.

With those changeless human teeth, Wune smiled. “I believe you,” she offered. “You say you know nothing about your nature, your talents. And I think you mean that.”

“I do.”

“Look at the chest of my suit, will you? Stare into the flat hyperfiber. Yes, here. Do you see your own reflection?”

His body had changed during these last few minutes. Alone had felt the new arms sprouting, the design of his legs adjusting, and without willing it to happen, he had acquired a face. It was a striking and familiar face, the purple flesh shot with gossamer threads of gold.

“I almost wish I could do that,” Wune confessed. “Reinvent myself as easily as you seem to do.”

He could think of no worthy response.

“Do you know what a chameleon is?”

Alone said, “No.”

“You,” she said. “Without question, you are the most natural, perfect chameleon that I have ever had the pleasure to meet.”

Simply and clearly, Wune explained how a solitary wanderer might secretly slip inside the Ship. Then as she grew drowsy again, the Remora wished her chameleon friend rich luck and endless patience. “I hope you find whatever you are hunting,” she concluded. “And that you avoid whatever it is that you might be fleeing.”

Alone offered thankful words, but he had no intention of accepting advice. Once Wune was asleep, he picked a fresh direction and walked away. For several centuries, he wandered the increasingly smooth hull, watching as the galaxy— majestic and warm and bright—rose slowly to meet the Great Ship. Now and again, he was forced to hide in the open. Practice improved his techniques, but he couldn’t shake the sense that the Remoras were still watching him, despite his tricks and endless caution. He certainly eavesdropped on them, and whenever Wune’s name was mentioned, he listened closely. Never again did her voice find him. But others spoke of the woman with admiration and love. Wune had visited this bubble city or that repair station. She had talked to her people about the honor of serving the Great Ship and the strength that came from mastering the evolution of your own mortal body. Then she was dead, killed by a shard of ice that slipped past every laser. Alone absorbed the unexpected news. He didn’t understand his emotions, but he hid where he happened to be standing and for a full year did nothing. Wune was the only creature with whom he had ever spoken, and he was deeply shocked, and then he was quite sad, but what wore hardest was the keen pleasure he discovered when he realized that she was dead but he was still alive.

Eventually he wandered back to the Ship’s trailing face, slipping past the bubble cities and into the realm of giant engines. Standing before one of the towering nozzles, Alone recalled Wune promising small, unmonitored hatches. Careless technicians often left them unsecured. With a gentle touch, Alone tried to lift the first hatch, and then he tried to shove it inwards. But it was locked. Then he worked his way along the base of the nozzle, testing another fifty hatches before deciding that he was mistaken. Or perhaps the technicians had learned to do their work properly. But having little else to do, he invested the next twenty months toying with every hatch and tiny doorway that he came across, his persistence rewarded when what passed for his hand suddenly dislodged a narrow doorway.

Darkness waited, and with it, the palpable sense of great distance.

He crawled down, slowly at first, and then the sides of the nearly vertical tunnel pulled away from his grip.

Falling was floating. There was no atmosphere, no resistance to his gathering momentum. Fearing that someone would notice, he left the darkness intact. Soon he was plunging at a fantastic rate, and that’s when he remembered Wune cautioning, “These vents and access tubes run straight down, sometimes for hundreds of kilometers.”

His tube dropped sixty kilometers before making a sharp turn.

The impact came without warning. One moment, he was mildly concerned about prospects that he couldn’t measure, and the next moment saw discomfort and flashes of senseless light as his neural net absorbed the abuse. But he never lost consciousness, and he soon felt his shattered pieces flowing together, making healing motions that continued without pause for three hours.

A familiar voice found him then.

Lying in the dark, unable to move, something quiet came very close and then said, “The cold,” before falling silent again.

He didn’t try to speak.

Then after a long while, the voice said, “For so long, cold.”

“What is cold?” Alone whispered.

“And dark,” said the voice.

“Who are you?” he asked.

The voice said, “Listen.”

Alone remained silent, straining to hear any sound, no matter how soft or fleeting. But nothing else was offered. Silence lay upon silence, chilled and black, and he spent the next long while trying to decipher which language was used. No human tongue, clearly. Yet those few words were as transparent and simple as anything he had heard before.

Once healed, he seeped light.

The engine’s interior was complex and redundant, and most of its facilities were scarcely used. Except for the occasional crackling whisper, radio talk never reached him. He could wander again. Happy, he discovered a series of nameless places where the slightest frosting of dust lay over every surface, that dust never disturbed. Billions of years of benign neglect promised seclusion. No one would find him in this vastness, and if nothing else happened in his life, all would be well.

Centuries passed.

Technicians and their machines traveled through these places, but always bound for other, more important locations.

Hiding was easy inside the catacombs.

The Ship gave warning when the overhead engine was about to be fired. Great valves were opened and closed, vibrations traveling along the sleeping tubes. A deeper chill could be felt as lakes of liquid hydrogen were prepared for fusion. Alone always found three sites where he could quickly find shelter. His planning worked well, and he saw no reason to change what was flawless. And then one day, everything changed. Alone was sitting inside a minor conduit, happily basking in a pool of golden light leaking from his inexplicable body. He was thinking about nothing of consequence. And then that perfect instant was in the past. There was a deep rumble and the ominous feel of dense fluids on the move, and before he could react, he was picked up and carried along by a hot viscous and irresistible liquid. Not hydrogen, and not water either. It was some species of oil dirtied up with odd metals and peculiar structures. He was trapped inside juices and passion, life and more life, and he responded with a desperate scream.

Tendrils touched him, trying to bury inside him.

He panicked, kicked and spun hard. Then he pulled his body into the first disguise that occurred to him.

Electric voices jabbered.

A language was found, and what surrounded him said in the human tongue, “It is a Remora.”

“Down here?”

“Tastes wrong,” a third voice complained.

“Not hyperfiber, this shell isn’t,” said a fourth.

The voices never repeated. This oily body contained a multitude of independent, deeply communal entities.

“The face is,” said another.

“Look at the face.” Another.

“You hear us, Remora?”

“I do,” Alone allowed.

“Are you lost?”

He knew the word, but its precise meaning had always evaded him. So with as much authority as possible, he said, “I am not lost. No.”

In an alien language, the multitude debated what to do next.

Then a final voice announced, “Whatever you are, we will leave you now in a safe place. For this favor, you will pay us with your praise and thanks. Do this and win our respect. Otherwise, we will speak badly of you, today and for the eternity to come.”

He was spat into a new tunnel—a brief broad hole capped with a massive door and filled with magnetic filters, meshed filters, and a set of powerful grasping limbs. The limbs gathered him up. He immediately transformed his body, struggling to slide free. But his captors tied themselves into an enormous knot, their grip trying to crush him. Alone felt helpless. He panicked. Wild with terror, fresh talents were unleashed, and he discovered that when he did nothing except consciously gather up his energies, he could eventually let loose a burst of coherent light—an ultraviolet flash that jumped from his skin, scorching the smothering limbs—and he tumbled back onto the mesh floor.

A second set of limbs emerged, proving stronger, more careful.

Alone adapted his methods. A longer rest produced an invisible but intense magnetic pulse. The mechanical arms flinched and died, and then he changed his shape and flowed out from between them. The chamber walls and overhead door were high-grade hyperfiber. With brief bursts of light, he attacked the door’s narrow seams. He attacked the floor. Security AIs made no attempt to hide their presence, calmly studying the ongoing struggle. Then a pair of technicians stepped through an auxiliary door—humans wearing armored lifesuits, complete with helmets that offered some protection to their tough, fearful minds.

The man asked the woman, “What is that thing?”

“I don’t damn well know.”

“You think it’s the Remora’s ghost?”

“Who cares?” he decided. “Call the boss, let her decide.”

The humans retreated. Fresh arms were generated, slow and massive but designed just moments ago to capture this peculiar prize. Alone was herded into a corner and grabbed up, and an oxygen wind blew into the chamber, bringing a caustic mist of aerosols designed to weaken any normal machine. Through the dense air and across the radio spectrum, the humans spoke to him. “We don’t know if you can understand us,” they admitted. “But please, try to remain still. Pretend to be calm. We don’t want you hurt, we want you to feel safe, but if you insist on fighting, mistakes are going to be made.”

Alone struggled.

Then something was with him—a close, familiar presence—and the voice said, “The animals.”

Alone stopped fighting.

“They have us,” said the voice.

He listened to the air, to the empty static.

But whatever spoke to him was already gone, and that’s when a low whistling noise began to leak out of the prisoner—a steady sad moaning that stopped only when the ranking engineer arrived.

“I think you do understand me.” He stared at the woman. Except for a plain white garment, she wore nothing. No armor, no helmet.

“My name is Aasleen.”

Aasleen’s face and open hands were the color of starless space. She was speaking into the air and into an invisible microphone, her radio words finding him an instant before their mirroring sound.

The woman said, “Alone.”

He wasn’t struggling. Doing nothing, he felt his power growing quickly, and he wondered what he might accomplish if held this pose for a long time.

“That’s your name, isn’t it? Alone?”

He had never embraced any name and saw no reason to do so now.

With her nearly black eyes, Aasleen studied her prisoner. And as she stood before him, coded threads of EM noise pushed into her head. Buried in her organic flesh were tiny machines, each speaking with its own urgent, complex voice. She listened to those voices, and she watched him. Then she said one secret word, silencing the chatter, and that’s when she approached, walking forward slowly until he couldn’t endure her presence anymore.

He made himself invisible.

She stopped moving toward him, but she didn’t retreat either, speaking quietly to the smear of nothing defined by the giant clinging limbs.

“Twisting ambient light,” she said. “I know that trick. Metamaterials and a lot of energy. You do it quite well, but it’s nothing new.”

Alone remained transparent.

“And I understand how you can alter your shape and color so easily. You’re liquid, of course. You only pretend to be solid.” She paused for a moment, smiling. “I once had a pet octopus. He had an augmented brain. To make me laugh, he used to pull himself into the most amazing shapes.”

Alone let his body become visible again.

“Step away,” he pleaded.

Aasleen stared at him for another moment. Then she backed off slowly, saying nothing until she had doubled the distance between them.

“Do you know what puzzleboys are?” she asked.

He didn’t answer.

“Puzzleboys build these wonderful, very beautiful machines—hard cores clothed with liquid exteriors. Their devices are durable and inventive. Their best machines are designed to survive for ages while crossing deep space.” Aasleen paused, perhaps hoping for a reaction. When she grew tired of the quiet, she explained, “Puzzleboys were like a lot of sentient species. They wanted the Great Ship for themselves. Thousands of worlds sent intergalactic missions, but my species won the race. I rode out here on one of the earliest starships. Among my happiest days is that morning when I first stood on the Ship’s battered hull, gazing down at the Milky Way.”

He said, “Yes.”

“You know the view?”

“Yes.”

She smiled, teeth showing. “A couple thousand years ago, as we were bringing the Great Ship into the galaxy, puzzleboys started singing their lies. They claimed they’d sent a quick stealthy mission up here. The laws of salvage are ancient—far older than my baby species. Machines can’t claim so much as a lump of ice for their builders. But the aliens claimed that they’d shoved one of their own citizen’s minds into a suitable probe. Like all good lies, their story has dates and convincing details. It’s easy to conclude that their one brave explorer might have actually reached the Great Ship first. If he had done that, then this prize would be theirs. At least according to these old laws. The only trouble with the story is that the mission never arrived. I know I never saw any sign of squatters. Which is why we’ve made a point of insulting that entire species, and that’s why the legal machinery of this cranky old galaxy has convincingly backed our claim of ownership.”

Quietly, he said, “Puzzleboys.”

“That’s a human name. A translation, and like most approximations, inadequate.”

With a burst of radio, the species’ name was offered in its native language.

“Do you recognize it?” asked Aasleen.

He admitted, “I don’t, no.”

“All right.” She nodded. A thin smile broke and then vanished again. “Let’s have some fun. Try to imagine that somebody we know, some familiar civilization, dreamed you up and sent you to the Great Ship. Maybe they borrowed puzzleboy technologies. Maybe you’ve sprung from a different engineering history. Right now, I’m looking at a lot of data. But despite everything I see, I can’t pick one answer over the others. Which is why this so interesting. And fun.”

Alone said nothing.

She laughed briefly, softly. “That leaves me with a tangle of questions. For instance, do you know what scares me about you?”

He took a moment before asking, “What scares you?”

“Your power supply.”

“Why?”

Aasleen didn’t seem to hear the question. “And I’m not the only person sick with worry,” she admitted. She closed one of her eyes and opened it again abruptly. “Miocene,” she said, and sighed. “Miocene is an important captain. And you’re considered a large enough problem that, right now, that captain is sitting inside a hyperfiber bunker three kilometers behind me. Three kilometers is probably far enough. If the worst happens, that is. But of course nothing is going to go bad now. As I explained to Miocene and the other captains, you seem to have survived quite nicely and without mishap, possibly for many thousands of years. What are the odds that your guts are going to fail today, in my face?”

He considered his nature.

“Do you have any idea what’s inside you?”

“No,” he admitted.

“A single speck of degenerated matter. Possibly a miniature black hole, although you’re more likely a quark assemblage of one or another sort.” She sighed and shrugged, adding, “Regardless of your engine design, it is novel. It’s possible, yes, and I have a few colleagues who have done quite a lot of work proving that this kind of system might be used safely. But to see something like you in action, and to realize that you’ve existed for who-knows-how-long, and apparently without demanding any significant repair…

“Alone,” she said, “I am a very good engineer. One of the best I’ve ever met, regardless of the species. And I just can’t believe in you. Honestly, it’s impossible for me to accept that you are real.”

“Then release me,” he begged.

She laughed.

He watched her face, her nervous fingers.

“In essence,” she continued, “you are a lucid entity carrying a tiny quasar inside your stomach. A quasar smaller than an atom and enclosed within a magnetic envelope, but massive and exceptionally dense.”

“Quasar,” he repeated.

“Matter, any matter, can be thrown inside you, and if only a fraction of the resulting energy is captured, you will generate shocking amounts of power.”

He considered her explanation. Then with a quiet tone, he mentioned, “I have seen the Ship’s engines firing.”

“Have you?”

“Next to them, I am nothing.”

“That’s true enough. In fact, I’ve got a few machines sitting near us that can outstrip your capacities, and by a wide margin. But as Submaster Miocene has reminded me, if your magnetic envelope is breached, and if your stomach can digest just your own body mass, the resulting fireworks will probably obliterate several cubic kilometers of the Ship, and who knows how many innocent souls.”

Alone believed her. But then he remembered that good lies have believable details and he didn’t feel as certain.

Aasleen smiled in a sad fashion. “Of course I don’t know exactly what would happen, if your stomach got loose. Maybe it has safety mechanisms that I can’t see. Or maybe its fire would reach out and grab my body, and everything else in this room would be consumed, as well as Miocene…and with that, the Great Ship would be short one engine, and the survivors would have an enormous hole in the hull, spewing poisons and nuclear fire.”

“I won’t fail,” he promised.

She nodded. “I think that’s an accurate statement. I know I want to believe that both of us are perfectly safe.”

“I won’t hurt the Ship.”

“All right. But why do you feel certain?”

He said, “Because I am.”

Aasleen closed her eyes, once again concentrating on the machines inside her head.

“Please,” said Alone. “Let me go free.”

“I can’t.”

He changed his shape.

Aasleen’s eyes opened. “I know that story about you and Wune. My guess? That you’d take on my appearance like you did hers.”

But he hadn’t. He had no limbs now, no face. To the eye, he looked like a ball of hyperfiber with giant rockets on one hemisphere, thick armor on the other. Using a hidden mouth, he promised, “I won’t do any harm. I shall not hurt anyone and I will never injure the Ship.”

“You just want to left by yourself,” she said.

“Nothing else.”

“But why?”

He had no response.

“Which leads us to another area of deep concern,” she continued. “A machine built by unknown hands is discovered wandering inside another machine built by unknown hands. But there seems to be two mysteries, there might be only one. Do you understand what I mean?”

He said, “No.”

“Two machines, but only one builder.”

He didn’t react.

She shook her head. “We don’t know how old the Great Ship is. Not precisely, but we have informed guesses. And no matter how well-engineered you appear to be, I don’t think you’re several billion years old.”

He remained silent.

Aasleen took one step closer. “There’s the third terror involving you: a captain’s nightmare. Maybe you are the puzzleboys’ machine. Or you’re somebody else’s representative. Either way, if you arrived here on the Ship before any human did, and if there’s a lost soul inside whatever passes for your mind…well, then it’s possible that a different species might legally claim possession over the wealth and impossibilities that the Great Ship offers. And at that point, no matter how sweet your engineering is, your fate is out my hands…”

Her voice trailed away.

She took a tiny step forward.

“I have no idea,” he said. “I don’t know what I am. I know nothing.”

The tiny machines inside Aasleen were speaking rapidly again.

“I’m watching your mind,” she confessed. “But I’m not at all familiar with its neural network. It’s a sloppy design, or it’s revolutionary. I don’t know enough to offer an opinion.”

“I wish to leave now,” he said.

“In the universe, there are two kinds of unlikely,” Aasleen warned. “The Great Ship is one type—never attempted or even imagined, but achievable, provided someone has time and the muscle to make it real. And then there’s the implausible that you imagine will come true, and one day your worst fears turn real. If the Great Ship belongs to someone else, then my species has to surrender our claim. And even though I believe that I am a good and charitable soul, I don’t want that to happen. Facing that prospect, I would fight to keep that from happening, in fact.”

Alone did nothing, gathering his strength.

“And even if you are safe as rain,” she said, “I don’t relish the idea of you wandering wherever you like. Not on my ship. Certainly not until we can find the answers to all these puzzles.”

Without warning, Alone lost his shape, turning into a hot broth that tried to flow around the grasping arms.

The arms seemed to expect his trick, quickly creating one deep bowl that held him in place.

“I promise,” said Aasleen. “You’ll be somewhere safe. We will keep you comfortable. And as much as possible, you’ll be left alone. Not even Miocene wants to torment you. And that’s why a special chamber is being prepared—”

A new talent emerged.

The liquid body suddenly compressed itself, collapsing into a tiny dense and radiant drop hotter than any sun. And as the bowl-shaped limbs struggled to keep hold of this fleck of fire, Alone stole a portion of their mass, turning it into energy, shaping a ball of white-hot plasma.

And with that, he shrank into an even tinier, hotter bit of existence.

Aasleen turned and ran.

The arms were pierced. Not even the hyperfiber floor could resist his descent. He struck and sank out of sight, and when he was beneath the floor, hyperfiber turned into a bed of pale pink granite, and much as a ship passed between the stars, he was slicing quickly through what felt much like nothing.

7

Creating a narrow hole, Alone fell.

The hole was lined with compressed, distorted magma that flowed and bubbled and soon hardened above him. But despite the minuscule trail, his enemies would follow. He felt certain. Alone had value in their eyes, or he was dangerous, or they simply could not approve of his continued existence. Whatever their reasons, Aasleen and the captains would go to considerable trouble to chase him. But the Great Ship was full of holes and tunnels, and it occurred to him that his enemies would simply gather below him, waiting inside the next chamber.

To fool these hunters, Alone let his body balloon outwards, one final burst of blazing heat leaking out before his descent was finished.

Fifteen kilometers beneath Aasleen, the machine built a new chamber. It was a tiny realm, the spherical wall glowing red as the residual heat bled away, and he lay silent in the middle for long minutes before sprouting delicate fingers, pushing their tips into the cooling magma. Falling from above were vibrations—bright hard jarrings marking the closing and sealing of every hatch and orifice and superfluous valve. Then something massive and quite slow passed directly beneath him. But the subtle noises were never regular, never simple, creating distortions and echoes as the waves broke around empty spaces deep within the cold rock. Swim in one downward angle, and a large chamber would be waiting. Another easy line promised a more distant but far more extensive cavern. But what caught Alone’s interest was a line that might be an illusion, a flaw in the rock, perhaps, or it might be a tunnel leading nowhere. But that target was close. Alone pulled his body into a new shape. Looking like the worms common to a hundred billion worlds, he began slithering and shoving his way forward.

He missed his goal by eighty meters.

But instinct or a wordless voice urged him to pause and think again. What was wrong? An urge told him what to do, and he obeyed, following a new line until he was not only certain that he was lost but that the Great Ship was solid to its core, and his fate was to wander this cramped darkness until Time’s end.

Suddenly the rock beneath him turned to cultured diamond.

With the worm’s white-hot head, he pushed through the gemstone. The Great Ship was laced with countless tiny tunnels, and this was among the most obscure, barely mapped examples. He glowed brightly for a long moment, new eyes probing in both directions before one was chosen. Then inside a space too small for a human child to stand, he began to run—sprouting limbs as necessary, pushing off the floor and the sides and that low slick diamond ceiling. With every junction and tributary hole, he picked for no reason. Eventually he was hundreds of kilometers from his beginning point, random choice his guide until the moment when he realized that he was beginning to wander back toward his starting point. Then Alone decided to pause, listening to the diamond and the rock beyond. The next turn led to a dead end, and he backed out of that hole and hunkered down, and with a soft private voice asked, “What now?”

“Down,” the familiar voice coaxed.

Nothing else was offered. No other instruction was needed. He burned a fresh hole into the diamond floor, and after plunging three kilometers, his fierce little body exploded out into a volume of frigid air that stretched farther than the light of his body could reach.

Alarmed, he made himself black as space.

He fell, and a floor of water and carbon dioxide ice slapped him when he struck bottom.

The cavern was five kilometers in diameter, bubble-shaped and filled with ancient ice and a whisper of oxygen gas. Except for the dimpled footprints of one robot surveyor, there was no trace of visitors. No human had ever stepped inside this place. But as a precaution, Alone erased his tracks, and where his warmth had distorted the ice, he made delicate repairs.

A walker’s existence gave way to the sessile life. He moved only to investigate his new home. Every sealed hatch leading out into the Ship was studied, and he prepared three secret exits that wouldn’t appear on the captains’ maps. Sameness made for simple memories. The next seventeen thousand years were crossed without interruption. Life was routine, and life was silent and unremarkable, and the old sense of fear subsided into a slight paranoia that left each sliver of Time sweet for being pleasantly, unashamedly boring.

Doing nothing was natural.

For long delicious spans, the entity sat motionless, allowing his heat to gradually melt the ice. Then he would cool himself and his surroundings would freeze again, and he would pretend to be the old ice. With determination and a wealth of patience, he imagined billions of years passing while nothing happened, nothing in this tiny realm experiencing any significant change. Sometimes he sprouted a single enormous eye, and from another part of his frigid body he emitted a thin rain of photons that struck the black basalt ceiling and the icy hills around him, and with that eye designed for this single function, he would slowly and thoroughly study what never changed, and with his mind he would try to imagine the Ship that he could not see.

“Speak to me,” he might beg.

Then he would wait, wishing for a reply, tolerant enough to withstand a year and sometimes two years of inviting silence.

“Speak,” he would prompt again.

Silence.

Then he might offer a soft lie. “I can hear you anyway,” he would claim. “Just past my hearing, you are. Just out of my reach, out of my view.”

But if the strange voice was genuine, then its maker was proving itself more stubborn even than him.

Seventeen millennia and thirty-seven years passed, and then with a thunderous thud, a hatch on one wall burst inward. Unsealed for the first time, the open door let in a screaming wind and a brigade of machines—enormous swift and fearless assemblages of muscle and narrow talents that knew their purpose and had only so much time to work.

Alone was terrified, and he was enthralled. Imagining that he could escape at will, he retreated to the chamber’s center. But then the other hatches exploded inwards, including a big opening at the apex of the ceiling. Machines began to burrow into the ice and string lights, and then they carved the black walls and built a second, lower ceiling. And all the while, they were leaking enough raw heat that the ancient glacier began to melt, transformed into fizzy water and gas.

Alone huddled inside the rotting shards of the ice.

Each of his emergency exists were either blocked or too close to active machines. The chamber floor was quality hyperfiber, difficult to pierce without creating a spectacle. Alone pretended to belong to the floor. For the next awful week, he did nothing but remain still. Then the ice had melted and the first wave of machinery vanished, replaced by different devices that worked rapidly in smaller ways, but with the same tenacious purpose.

Mimicking one common machine, he drifted to the new lake’s surface.

A shoreline was being constructed from cultured wood and young purple corals and farm-raised shellfish, everything laid across a bed of glassy stone filled with artificial fossils—ancestors to the chamber’s new residents. Humans stood beside the aliens, the species speaking through interpretive AIs. The aliens wore broad purple shells, and they were happiest when their gills lay in the newly conditioned water. The humans wore uniforms of various styles, different colors. One uniform had the bright reflective quality of a mirror, and the woman inside it was saying, “Beautiful, yes.” Then she knelt down and sucked up a mouthful of the salted, acidic water. Spitting with vigor, she said, “And a good taste too, is it?”

The aliens swirled their many feet and the fibrous gills, stirring up their lake. Then their chittering answers were turned into the words, “We are skeptical.”

“To your specifications,” said the woman. “I pledge.”

The aliens spoke of rare elements that needed to be increased or abolished. Proportions were critical. Perfection was the only satisfactory solution.

“It shall be done,” the captain promised.

The aliens claimed to be satisfied. Confident of success, they slithered into the deeper water, plainly enjoying their new abode.

The captain looked across the lake, spying one machine that was plainly doing nothing.

With a commanding tone, she said, “This is Washen. We’ve got a balky conditioner sitting in the middle. Do you see it?”

Quietly, Alone eased beneath the surface, changing his shape, merging with the glassy sediment. His disguise was good enough to escape the notice of watching humans and machines. As he waited, he gathered enough power to make a sudden explosive escape. But then the artificial day faded, a bright busy night taking hold, complete with the illusion of scattered stars and a pale red moon; and it was an easy trick to assume the form of one shelled alien, mimicking its motions and chattering tongue, casually slipping out through the public entrance into a side tunnel that led to a multitude of new places, all empty.

8

Twenty centuries of steady exploration, and still the cavern had no end. Its wandering passageways were dry and often cramped, unlit and deeply chilled. The granite and hyperfiber were quite sterile. Humans and aliens didn’t wish to live in places like this. Machine species set up a few homes, but their communities were tiny and easily avoided. Once more, the habit of walking returned to his life. To help track his own motions as well as the passage of time, Alone would count his strides until he reached some lovely prime number, and then he would mark the nearest stone with slashes and dots that only he could interpret—apparently random marks that would warn him in another thousand years that not only had he had passed this way before, but he had been moving from this tunnel into that chamber, and if at all possible, he should avoid repeating that old route.

The voice found him more often now, but it was quieter and even harder to comprehend. Sometimes a whisper emerged from some slight hole or side pas-sage—like a neighbor calling to a neighbor from some enormous distance. But more often the voice was directly behind him, and it didn’t so much speak as offer up emotions, raw and unwelcome. The sadness that it gladly shared was deep and very old, but that black mood was preferable to the sharp, sick fear that sometimes took hold of Alone. One dose of panic was enough to make his next hundred days unbearable. Something was horribly wrong, the voice insisted. Alone couldn’t define the terror, much less the reasons, but he didn’t have any choice but believe what he felt. He had his solitude; there was no cause to be scared. No captains or engineers chased after him. Occasionally he slipped into some deep corner of the cavern, and for several months he would hide away, waiting for whatever might pass by. But nothing showed itself, and whatever the voice was, it was wrong. Mistaken. Alone was perfectly safe inside this private, perfect catacomb, and he welcomed no opinion that said otherwise.

One day, walking an unexplored passageway, he happened upon a vertical shaft. Normally he might have avoided the place. A human had been here first, leaving behind tastes of skin and bacteria and human oils. Leaking a faint glow, Alone spied the machine abandoned by this anonymous explorer: a winch perched on the edge of the deep shaft, anchored by determined spikes. The sapphire rope was broken. The drum was almost empty, but the winch continued to turn—an achingly slow motion that for some reason fascinated the first soul to stand here in a very long while.

After several days of study, Alone touched the drum, and that slight friction was enough to kill what power remained inside the superconductive battery. How long had it been here, spinning without purpose? And what was inside the hole, waiting at the other end of the broken blue thread?

Alone snapped two handles from the winch and uncoiled the remaining sapphire rope, tying one handle to one end. Then he dropped the handle into the dark shaft. Two hundred meters, and there was no bottom. Then he tied the rope’s other end to the winch and climbed down. The shaft turned to hyperfiber, slick and vertical, and then its sides pulled away. When Alone couldn’t reach easily from one side to the other, he let go, falling and making his body brighter as he fell, watching the dangling handle fly past. Then feeling no one but himself, he lit the entire chamber with his golden fire.

A human shape lay upon the flat floor.

Alone turned black and cold again, and he dropped hard and repaired his body and then carefully crept close to the motionless figure.

For three days, nothing changed.

Then he brightened, just slightly, straddling the figure. The human male hadn’t moved in decades, perhaps longer. There was enough thread on the winch to put him down here, but it must have broken unexpectedly. The hyperfiber floor showed blood where the man struck the first time, hard enough to shatter his tough bones and shred his muscles. But humans can recover from most injuries. This stranger would have healed and soon stood up again, and probably by a variety of means, he had worked to save himself.

Most of the Ship’s passengers carried machines allowing them to speak with distant friends. Why didn’t this man beg for help? Perhaps that machinery failed, or this hole was too deep and isolated, or maybe he simply came to this empty place without the usual implements.

Reasons were easy, answers unknowable.

Whatever happened, the man had lived inside this hole for some months and perhaps several years. He had brought food and water, but not enough of either to last long. The cold that Alone found pleasant would have stolen away the body’s precious heat, and the man starved while his flesh lost its moisture, reaching a point where it could invent no way to function. Yet the man never died. With his last strength, he stripped himself of his clothes and made a simple bed, his pack serving as his pillow, and then he lay on his back with his eyes aimed at the unreachable opening, his face turning leathery and cold and blind.

The eyes remained open but dry as stone. They might not have changed for centuries, and nobody had ever found this man, and perhaps no one had noticed his absence.

Alone considered the implications of each option.

Eventually and with considerable caution, he opened the pack and thoroughly inventoried its contents. What was plainly useful he studied in detail, particularly the sophisticated map of this cavern system. Then he carefully returned each item to where it belonged, and laid the pack beneath the unaware head. That frozen, wasted body weighed almost nothing. A good hard shake might turn the dried muscle to dust. Yet he was careful not to disturb anything more than absolutely necessary, and without a sound, he retreated. The lower length of sapphire lay nearby, coiled into a neat pile. He tied one end to the second handle, and despite the distance and darkness, he managed a perfect toss on his first attempt, the two handles colliding and then wrapping together, and he climbed past the rough knot, pulling it loose and letting the lower rope fall away before he continued his climb out from the hole.

More centuries passed; little if anything changed. But there were a few episodes—intuitive moments when the bright gray fear took hold, when some nagging instinct claimed that he was being sloppy, that he was being pursued. Three times, Alone found marks resembling his own but obviously drawn by another hand. And there was one worrisome incident when he slipped aside and waited only thirteen days before a solitary figure followed him down the long tunnel. The biped was towering and massive, covered with bright scales and angry spikes, and the low ceiling forced him to walk bent over inside the passageway, both hands carrying an elaborate machine that resembled a second head.

Mechanical eyes and a long probing nostril studied the rock where Alone had stepped, teasing out subtle cues. With a hunter’s intensity, the creature slowly moved to a place where the second head noticed that the trail had vanished, and the machine whispered a warning, and the harum-scarum turned in time to see an amorphous shape sprout long limbs, and without sound, silently race away.

After that, Alone adapted his legs and gait, changing his stride, hopefully becoming less predictable. But he refused to abandon the cavern. His home was far too large to be searched easily or in secret, and he had nearly walked every passageway, every room—a hard-acquired knowledge that he would have to surrender if he journeyed anywhere else.

Most encounters came through chance, fleeting and harmless. As the millennia passed, human numbers had swollen, but other species plainly outnumbered the Ship’s lawful owners. Aliens wore every imaginable body, and there were always new species waiting to surprise. One glimpse in the dark or some long study at a safe distance didn’t make an expert, but Alone had adequate experience to gain several rugged little epiphanies: Life must be relentless, and it had to be astonishingly imaginative. Every living world seemed unique, and those oceans of living flesh were able to thrive on every sort of unlikely food and bitter breath. The beasts that came slipping through his home drank water, salty or clear, acidic or alkaline, or their drinks were chilled and laced with ammonia, or they wore insulated suits and downed pitchers of frigid methane, or they sucked on peroxides, on odd oils, while quite a few drank nothing whatsoever. Yet despite that staggering range of form and function, every creature was curious, peering into some black hole, sometimes slipping fingers and antennae into places never touched before—if not hunting for invisible, legendary entities, then at least seeking the simple, precious novelty of Being First.

On occasion, Alone watched visitors coupling. One eager pair of humans fell onto a mat of glowing aerogel, naked and busy, and standing just a few meters away, immersed in darkness, Alone observed as they bent themselves into a series of increasingly difficult poses, grunting occasionally, then finally shouting with wild voices that echoed off the distant ceiling. Then their violence was finished, and the woman said to the man, “Is that all there is?” and her lover called her a harsh affectionate name, and she laughed, and he laughed, and after drinking the brown alcohol from a treasured bottle, the performance began again.

More centuries and thousands of kilometers were slowly, carefully traversed. And then came one peculiar second where he heard what sounded like a multitude passing through the cavern’s largest entrance. The presence of many was felt; he smelled their collective breath. They might whisper respectfully and try to move like ghosts, but there were too many feet and mouths, too many reasons to praise the solitude and beg their neighbors to be silent. Alarmed, he approached the newcomers and then followed them, and from a sober distance he watched as they assembled at the center of the cavern’s largest chamber. A quick count found twenty thousand bodies and a staggering variety of species, and after an invisible signal was given, they began to talk in one shared voice. He heard rhythmic chanting, the sloppily performed songs. Normally he would have fled any spectacle, but the strangers were singing about the Great Ship, begging for its blessings and its wisdom. And hope upon hope, the Ship’s voice.

Using every trick, Alone approached unseen.

The celebration was joyous, and it was senseless. But he felt the urgency and earnest passion. At least a hundred alien species were represented. But the lighting was minimal, and hovering at the edges, it was impossible to observe the full crowd, much less comprehend more than a fraction of what was being said.

“We thank the Ship,” he heard.

Then from someplace close, one enormous voice chanted, “For the home and safety You give to us, we thank You!”

“You are a mystery,” the nearest souls declared.

Alone hovered at the edge of the crowd, unnoticed but near enough to touch the backs and feel the leaked heat of bodies.

A hill of smooth basalt stood on the cavern floor, and perched on the summit was a human male crying out, “For so long and for so far, You have journeyed. We cannot measure the loneliness You endured in Your wanderings. But in thanks for Your shelter, we give You our companionship. For Your speed, we give You purpose. After the countless years of being empty and dead, we have made You into a vibrant, thriving creature! At long last, the Great Ship lives! And we hear Your thanks, yes! In our dreams, and between our little words, we hear You!”

Precisely when Alone turned to flee, he couldn’t say.

He was at a loss to understand which word triggered the wash of emotion, even as he was rushing away from the room and its densely packed bodies…even as a few of the less devoted worshippers heard what might be a moan and turned in time to notice the faint but unmistakable glow, red as a dying ember, racing off on legs growing longer by the stride.

9

Ten thousand and forty-eight years after first discovering the hole, Alone returned. The winch remained fixed in place, but someone else had visited, and possibly more than once. Boot prints showed in the dust. He could smell and taste signs of a second human. But nobody had stood up on this ground for a very long while, and when he went below, he found the body exactly where he had left it—only more dried, more wasted. More helpless, if that was possible.

Once again, Alone emptied the pack of its belongings, but this time he tenaciously studied the design and contents of even the most prosaic, seemingly useless item. He taught himself to read. He mastered the old, once-treasured machines that had thoroughly recorded one life. The mummified man had a long, cumbersome name, but he answered easiest to Harper. Eyes pushed against the digital readers, Alone marveled at scenes brought by Harper from the distant Earth. Here were glimpses of strange brightly lit lives, the toothy faces of a family, and a sequence of lovers. But each of those individuals were left behind when Harper sold every possession, surrendering his home and safety for a ticket to ride the Great Ship—embarking on a glorious voyage to circumnavigate the Milky Way.

Between the man’s arrival at Port Alpha and this subsequent disaster, barely fifty years passed. Which was no time at all. What’s more, Harper had filled his days with a single-minded hunt for the Ship’s ancient builders. Infused with a maniacal hunger, the human not only presumed that some grand and purposeful force had built the derelict starship, but the same force was still onboard, hiding in an odd corner or unmapped chamber, biding its time while waiting for that brave, earnest explorer that would discover its lair.

Harper intended to be that very famous man.

Alone studied every aspect of the lost life. There were gaps in the records, particularly near the end. But he wasn’t familiar enough with human ways to appreciate that another hand might have blanked files and entire days, erasing its presence from the story. What mattered was digesting the full nature of this alien beast, learning Harper’s manners and looks and duplicating his high, thin voice. Then Alone refilled the pack. But this time, he left the hole with the lost man’s possessions carried under what looked like a human arm.

At the top of the hole, he transformed his face, his body.

There were many ways to be alone. The next weeks were spent duplicating the voice and gestures on the digitals. Then he abandoned the safety of the cavern. The local time was night, as he had planned. Obeying customs learned only yesterday, Alone summoned a cap-car that silently carried him halfway around the Ship. He paid for the service with funds pulled from an account that hadn’t been touched for thousands of years. The modest apartment hadn’t seen this face for as long, but its AI said, “Welcome.” The master’s sudden reappearance didn’t cause suspicion or curiosity. Entering a home that he didn’t know, Alone spent the next ten days and nights studying the lost man. Then his apartment announced, “You have a visitor, sir.”

Baffled, he asked, “Who?”

“It is Mr. Jan.”

“Who is Mr. Jan?”

“I have no experience with the gentleman. But he claims to be your very good friend.”

Alone considered the implications.

“What shall I tell him, sir?”

“That I have no friends,” he replied.

“Very well.”

The matter seemed finished. But fifty-three minutes later, the apartment warned, “Mr. Jan is still waiting at your door, sir.”

“Why?”

“Apparently he wishes to speak with you.”

“But I’m not his friend,” Alone repeated.

“And I told him as much. But the man is quite upset about some matter, and he refuses to leave until he shares words with you.”

“Let him into the front hall.”

A narrow, nervous human crept inside the apartment. Mr. Jan had a familiar scent, and judging by the intricacy of the braids, he was quite proud of his thick red hair. The hallway was thirty meters long, which wasn’t long enough. The two figures stared at one another from opposite ends, and when Mr. Jan took a small step forward, the other soul said, “No. Come no closer, please.”

“I understand,” the guest whispered. “Sure.”

“What do you want with me?”

What did Mr. Jan want? The possibilities were too numerous or too vast for easy explanations. He gazed down at his pale hands, as if asking their opinion.

Then quietly and very sadly, he said, “I’m sorry.”

“Sorry?”

“Yes I am.”

Alone felt sick to be this near a stranger. But his voice remained calm, under control. “For what are you apologizing?”

Mr. Jan straightened his back, surprised by those words, and on reflection, angered by them too. “I’m apologizing for everything, of course! I’m sorry for the entire mess!”

Alone waited, his new face unchanged.

“But these things weren’t just my fault,” the visitor insisted. “You used me, Harper. And I know you made fun of me. We were supposed to have a business relationship, a partnership. I heard quite a few promises about money, but did you give me even half of what I’d earned?”

“What did I give you?”

“None of it. Don’t you remember?”

“Then I must have cheated you,” Alone observed.

“‘Cheat’ doesn’t do it justice,” Mr. Jan insisted.

Alone wasn’t certain what word to offer next.

“Look,” said Mr. Jan. “What I did…I was just trying to scare you. Taking you that deep, down where your nexuses couldn’t reach anybody. And then cutting the sapphire before you went down into that room. It looks bad, if you look at things that way. But it was meant to be a warning. Nothing else.”

“You were trying to scare me,” Alone guessed.

“Don’t you remember? I spelled out all of my reasons afterwards.” Mr. Jan looked at the granite floor and then the matching ceiling. With a stiff, self-absorbed voice, he said, “You heard me calling down to you. I know you heard, because you answered me. I told you that I was going to let you sit there and commune with the Great Ship until you promised to give me everything that I was owed.”

“I remember,” Alone lied.

“Money and respect. That’s what I wanted, that’s what I deserve. And that’s why I did what I did.” The walls were only partly tiled. Like the rest of the tiny apartment, the hallway was far from finished. Mr. Jan leaned against the shifting quasicrystals, beginning to cry. “All you needed to do…I mean this…was to say a few words to me. You could have just told me another lie. I never wanted to leave you down there. I’m not cruel like that. If you’d made any promises, anything at all, I’d have pulled you right out of there. Yes, I would have saved you in an instant.”

The voice faded.

“I should have done that,” Alone agreed. “Lying would have been right.”

“Well, I don’t know if that’s quite true.” The weeping man looked at his nemesis—a ghost that had stalked him for eons. “But listen, Harper. You have no respect for anyone but you. Yelling those insults up at me. Yes, you hurt me. Words like that…they last forever. They’re cutting me still, those awful things that you said to me.”

“I was wrong,” Alone agreed.

Mr. Jan looked at him. He took three steps forward, and when the other figure didn’t complain, he admitted, “I came back to the hole. You don’t realize that, but I did. I went there to check on you. After you fell into the coma, I used a little lift-bug to reach your body.”A trembling hand tugged at the braided hair. “I meant to bring you out, but I got scared. It looks bad, what happened, and I didn’t want trouble. So I scrubbed away every trace of me, from your field recorders and in here too. Then I convinced your apartment that I never existed and that you were always coming home tomorrow. In case anybody became curious about your whereabouts.”

“People can be curious,” Alone agreed.

Mr. Jan smiled grimly. Then he wiped at his eyes, adding, “I was always your best friend.”

Alone said nothing.

“You know, when you suddenly vanished, nobody noticed. Oh, they might ask me about you. Since they knew we were close. For several years, they’d wonder if I’d heard any noise from Crazy Harper and where you might have gone.”

“‘Crazy Harper’?”

“That’s what some of them called you. I never did.”

Alone made no remark.

For a long while, Mr. Jan concentrated on his mind, searching for courage to say, “I’m a little curious. How did you finally climb out of that hole?”

“There is a story,” Alone admitted. “But I don’t wish to tell it.”

Mr. Jan nodded, lips mashed together. Then he asked, “Does anyone know the story? About us, I mean.”

Silence.

Mr. Jan wrapped his arms around his chest and squeezed. “Not that you’re in terrible shape now. I mean, it’s not as if I murdered anybody.” He paused, dwelling for a moment on possibilities. Then he pointed out, “You lost time. I know, it was quite a lot of time. But here you are, aren’t you? And everything is back where it belongs.”

“I’ve told no one about my years.”

With a deep sigh, Mr. Jan said, “Good.”

“No one knows anything. Except for you, of course.”

The human nodded. He tried to laugh, but his voice collapsed into soft sobs. “I won’t tell, if you don’t.”

“I don’t know what I would say.”

Wiping at his wet face, Mr. Jan quietly asked, “What can I do? Please. Tell me how to make this up to you.”

Alone said nothing.

“I was wrong. I’ve done something criminal, and I’ll admit that much, yes.

And you should deliver the punishment. That’s the right solution. Not the captains, but you.” The smile was weak, desperate. “I promise. I’ll do whatever you tell me to do.”

Alone had no idea what to say, but then a memory took hold. He thought to smile, nodding knowingly. Then with quiet authority, Alone explained, “You will leave me. Leave here and climb to the Ship’s hull. Since you’re a criminal, you need to be where criminals belong. Live under the stars and help keep the hull in good repair.” Alone took a small step forward, adding, “The work is vital. The Great Ship must remain strong. There is no greater task.”

Mr. Jan straightened his back. “What?” He didn’t seem to understand. “You want me to work with the Remoras? Is that your punishment?”

“No,” said Alone. “I wish you to become a Remora.”

“But why would I?”

“Because if you do otherwise,” Alone replied, “other people, including the captains, will hear what you did to your good friend, Crazy Harper.”

The demand was preposterous. Mr. Jan shook his head and laughed for a full minute before his frightened, slippery mind fell back to the most urgent question. “How did you get out of that hole?”

Alone didn’t answer.

“Somebody helped you. Didn’t they?”

“The Great Ship helped me.”

“The Ship?”

“Yes.”

“The Ship pulled you out from that hole?”

“Yes.”

Mr. Jan looked at the sober face, waiting for any hint of a lie. But nothing in the expression gave hope, and he collapsed to the stone floor. “I just don’t believe you,” he sobbed.

But he did believe.

“The Ship needs you to walk on the hull,” Alone explained. “It told me exactly that. Until you are pure again, you must live with the followers of Wune.”

“For how long?”

“As long as is necessary.”

“I don’t know what that means.”

Alone hesitated. Then quite suddenly he was laughing, admitting, “I’m sorry, Mr. Jan. I don’t know either. Even with me, it seems, the Great Ship refuses to explain much about anything.”

Harper must have been a difficult, solitary man. No one seemed to have missed his face or companionship, and his sudden return caused barely a ripple of interest. Word spread that somebody was again living inside his apartment, and the apartment’s AI dutifully reported communications with acquaintances from the far-flung past. But the greetings were infrequent and delivered without urgency. Maintaining his privacy proved remarkably easy. For twenty busy years, Alone remained inside those small, barely furnished rooms. And the apartment never asked where its only tenant had been or why he had been detained, much less why this new Harper never needed to eat or drink or sleep. The machine’s minimal intelligence had been damaged by Mr. Jan. Alone spent a month dismantling and mapping his companion’s mental functions, and all that while he wondered if he was the same, his mind incomplete, mangled by clumsy, forgotten hands.

Harper had painted himself as an important explorer and an exceptionally brave thinker. Inside his pack, he had carried dated records about mysterious occurrences inside the Great Ship. But there were larger files at home, each one possessed by one broad topic and a set of tireless goals. In the man’s long absence, those files had grown exponentially. Alone uncovered countless stories about ghosts and monsters and odd lost aliens. Over thousands of years, one thin rumor of a Builder being seen by the first scout team had become a mass of rumors and third-hand testimonies, plus a few more compelling lies, and several blatant fakes that had been discounted but never quite set aside.

Believe just a fraction of those accounts, and it would be difficult not to accept that the Great Ship was full of ancient, inscrutable aliens—wise souls born when the Earth was just so many uncountable atoms cooking inside a thousand scattered suns.

Each resident species had its preferred Builder.

Humanoids like to imagine ancient humanoids; cetaceans pictured enormous whales; machine intelligences demanded orderly, nonaqueous entities. But fashions shifted easily and in confusing directions, dictating the key elements to the most recent fables. Each century seemed to have its favorite phantom, its most popular unmapped cavern, or one mysterious phenomenon that was fascinating yet never rose to a point where physical evidence could be found. But even a stubborn lack of evidence was evidence. Harper had reasoned that the Builders had to be secretive and powerful organisms, and of course no slippery wise and important creature would leave any trace of its passing. Skin flakes and odd tools were never found in the deep caves, much less a genuine body, because if hard evidence did exist, then the quarry wouldn’t be the true Builders. Would they?

One file focused on the Remora’s ghost.

On Alone.

He had discovered references about himself in Harper’s field recorder. But in his absence, new sightings and endless conjecture made for years of unblinking study. Alone absorbed every word, every murky image, fascinated by the mystery that he had walked through. According to most accounts, he was more real than the Whispers that haunted a mothballed spaceport. But people like Harper generally preferred the Clackers who supposedly swam inside the Ship’s fuel tanks, and the Demon-whiffs that were made of pure dark matter. Tens of thousands of years after the event, Alone watched the recording of him standing inside the empty hyperfiber tank—a swirl of cobalt light that could mean anything, or nothing—and he began to wonder if perhaps he wasn’t quite real back then. Only recently, after all of the steps and missteps, had he acquired that rare and remarkable capacity to stand apart from Nothingness.

For every portion of the hull where he was seen, Remoras and other crew-members and passengers had spotted at least ten more examples of the ghost wandering beneath the stars.

What if there was more than one Alone wandering loose?

He didn’t know what to believe. After he abandoned the hull, those sightings fell to the level of occasional, and no Remora pretended to have spotted Wune’s mysterious friend. In no file was there mention of Aasleen and the nightmare inside one of the Ship’s engines. Which meant that the captains and crew were good at keeping secrets, and what else did they know? A related file focused on shape-shifting machines currently lurking in the dark corners and deepest wastes. Alone’s cavern held a prominent but far from dominating place. Other realms seemed to be haunted by his kind. Dozens of sprawling, empty locations were named. But the only cavern to capture Alone’s imagination was named Bottom-

E. Again and again, he found sketchy accounts of tourists wandering down an empty passageway, and when they glanced over their shoulder, a smear of dim light was silently racing out of view.

Bottom-E was an even larger cavern than Alone’s old home. And if nothing else, it would provide the perfect next home.

But what if another entity like him already lived there?

After two decades of study and consideration, Alone made one difficult choice. He identified the humans who had tried to contact Harper on his return. Most were small figures, many with criminal records and embarrassing public files. But despite those same limitations, one man had all the qualifications to give aid to an acquaintance that he hadn’t seen for ages.

With Harper’s face and voice, Alone sent a polite and brief request.

Eighteen days passed before any reply was offered. The recorded digital showed a smiling man who began with an apology. “I was off. Wandering in The Way of Old. It’s an ammonia-hydroxide ocean. On a small scale, but it’s still a hundred cubic kilometers of murk and life, and that’s why I couldn’t get back to you, Harper.”

The man was named Perri.

“So you’re interested in Bottom-E,” the message continued. “I can’t promise much in the way of help. I haven’t seen more than one-tenth of one percent of the place. But there is one enormous room that’s worth the long walk. Its floor is hyperfiber, and a fine grade at that. And the ceiling is kilometers overhead and inhabited by the LoYo. They’re machines, not sentient as individuals but colonial in nature. A few thousand of their city-nests hang free from the rafters, and that’s one of the reasons for going down there.”

The grinning man continued. “The LoYo give that big room a soft, delicious glow. I’ve got good eyes, but even after a week in that, I couldn’t see far. The immediate floor and what felt like a distant, unreachable horizon. Once, maybe twice, I saw a light in the distance. I can’t say what the light was. But you know me, Harper. Don’t expect ghost stories. Usually the truth is a lot more interesting than what we think we want to see…

“Anyway, what I like best about Bottom-E, and that huge room in particular…what makes the trip genuinely memorable…is that when you walk on that smooth hyperfiber, and there’s nothing above you but the faint far-off glow of what could be distant galaxies…well, it’s easy to believe that this is exactly how it would have felt and looked just a couple billion years ago, if you were strolling by yourself, walking across the hull of the Great Ship.

“Understand, Harper? Imagine yourself out between the galaxies, crossing the middle of nothing.

“I think that’s an experience worth doing,” Perri said.

Then with a big wink, he added, “By the way. I know you keep to yourself. But if you feel willing, you’re more than welcome to visit my home. For a meal, let’s say. For conversation, if nothing else. I don’t think you ever met my wife. Well, I’ll warn you. Quee Lee likes people even more than I do, if you can believe that.”

Perri paused, staring at his unseen audience.

“You were gone a very long time,” he mentioned. “Jan claimed you were off chasing Clackers, and that’s what the official report decides too. Lost in the fuel tanks somewhere. But I didn’t hear any recent news about bodies being fished out of the liquid hydrogen, which makes me wonder if our mutual friend was telling another one of his fables.

“Anyway, good to hear from you again, Harper. And welcome back to the living!”

11

As promised, Bottom-E held one enormous room, and except for the occasional smudge of cold light on the high arching ceiling, the room was delightfully dark. Each step on the slick floor teased out memories. That lost and now beloved childhood returned to him, and Alone wasn’t just content, but he was confident that the next step would bring happiness, and the one after, and the one after that.

More than twelve hundred square kilometers of hyperfiber demanded his careful study. Unlike the hull, there was an atmosphere, but the air was oxygen-starved and nearly as cold as space. Like before, Alone’s habit was to follow a random line until an oddity caught his attention. Then he would stop and study what another visitor had left behind—a fossilized meal or frozen bodily waste, usually—and then he would attack another random line until a new feature caught his senses, or until a wall of rough feldspar defined the limits of this illusion.

For almost two years, he walked quietly, seeing no one else.

The LoYo were tiny and weakly lit, and there was no sign that they noticed him, much less understood what he was.

Perri’s mysterious glow failed to appear. But Alone soon convinced himself that he’d never hoped the story would prove real. One step was followed by the next, and then he would pause and turn and step again, defining a new line, and then without warning, there was a sliver of time when that simple cherished pattern failed him. He suddenly caught sight of a thin but genuine reddish light that his big eyes swallowed and studied, examining the glow photon by photon, instinct racing ahead of his intelligence, assuring him that this new light was identical to the glow he leaked when he was examining a fossilized pile of alien feces.

On his longest, quietest legs, Alone ran.

Then the voice returned. Decades had passed since the last time Alone felt its presence, yet it was suddenly with him, uttering the concept, “No,” wrapped inside a wild, infectious panic.

His first impulse was to stop and ask, “What do you want?”

But the red glow was closer now, and Alone’s voice, even rendered as a breathless whisper, might be noticed. If that other entity heard him, it could become afraid, vanishing by some secret means. The moment was too important to accept that risk. The end of a long solitude might be here, if only Alone was brave enough to press on. That’s what he had decided long ago, imagining this unlikely moment. He would accept almost any danger to make contact with another like him. But only now, caught up in the excitement, did Alone realize how much this mattered to him. He was excited, yes. Thrilled and spellbound. Every flavor of bravery made him crazy, and he refused to answer the voice or even pay attention when it came closer and grew even louder, warning him, “Do not.” Telling him, “No. They want, but they will not understand. Do not.”

The light was still visible, but it had grown weaker.

The intervening distance had grown.

The other Alone must have noticed something wrong. A footfall, a murmur. Perhaps his brother heard the voice too, and the wild, unapologetic fear had taken possession of him. Whatever the reason, the light was beginning to fade away, losing him by diving inside a little tunnel, abandoning this room and possibly Bottom-E because of one irresistible terror.

Alone had to stop his brother.

But how?

He quit running.

The voice that had never identified itself—the conscience that perhaps was too ancient, too maimed and run down, to even lend itself a name—now said to him, “Go away. This is the wrong course. Go!”

Alone would not listen.

Standing on that barren plain, he made himself grow tiny and exceptionally bright, washing away the darkness. In an instant, the enormous chamber was filled with a sharp white light that reached the walls and rose to the ceiling before vanishing in the next instant.

Then he was dark again, drained but not quite exhausted.

With the last of his reserves, Alone spun a fresh mouth, and in a language that he had never heard before—never suspected that he was carrying inside himself—he screamed into the newly minted darkness, “I am here!”

Suddenly a dozen machines emerged from their hiding places, plunging from the ceiling or racing from blinds inside the towering rock walls.

Alone tried to vanish.

But the machines were converging on him.

Then he grew large again, managing legs. But the power expended by his desperate flash and careless shout was too much, and too many seconds were needed before he would be able to offer the many kind of chase. After thousands of years, the door of a trap was closing over him, and in the end there wouldn’t even be the pleasure of a hard chase fought to the dramatic end.

12

Since their last meeting, the two organisms had walked separate lines—tightrope existences inspired by chance and ambition, deep purpose and the freedom of no clear purpose. An observer on a high perch, watching their respective lives, might have reasonably concluded that the two souls would never meet again. There was no cause for the lines to cross. The odd machine was quiet and modest, successfully avoiding discovery in the emptiest reaches of the Ship, while the engineer was busy maintaining the giant engines, and later, she was responsible for a slow-blooming career as a new captain. The remote observer would have been at a loss to contrive any situation that would place them together, much less in this unlikely terrain. Embarrassed, Aasleen confessed that she had had no good idea where Alone might have been and not been over these last tens of thousands of years. For decades, for entire centuries, she didn’t waste time pondering the device that she once cornered and then let get away. Not that she was at peace with her failure. She was proud of her competence and didn’t appreciate evidence to the contrary. Somewhere onboard the Great Ship was a barely contained speck of highly compressed matter, and should that speck ever break containment, then the next several seconds would become violent and famous, and for some souls, exceptionally sad.

This was a problem that gnawed, when Aasleen allowed it to. But as an engineer, she handed her official worries to the Submaster Miocene, and as a novice captain, she had never once been approached with any duty that had even the most glancing relationship to that old problem.

She told her story now, assuming that her prisoner would both understand what he heard and feel interested in this curious, quirky business.

Then several centuries ago, Aasleen and another captain met by chance and fell into friendly conversation. It was that other captain who mentioned a newly discovered machine-building species. Washen had a talent for aliens, Aasleen explained. Better than most humans, her colleague could decipher the attitudes and instincts of organisms that made no sense to a pragmatic, by-the-number soul like her. But the aliens, dubbed the Bakers, had been superior engineers. That’s why Washen mentioned them in the first place. She explained their rare genius for building inventive and persistent devices, and millions of years after their rise and fall and subsequent extinction, their machines were still scattered across the galaxy.

“Bakers is our name for them,” Aasleen cautioned. “It shouldn’t mean anything to you.”

Alone was floating above the cavern floor, encased in a sequence of cages, plasmas and overlapping magnetic fields creating a prison that was nearly invisible and seemingly unbreakable. Drifting in the middle of the smallest cage, he was in a vacuum, nothing but his own body to absorb into an engine that everybody else seemed to fear. With a flickering radio voice, he agreed. “I don’t know the Bakers.”

“How about this?” Aasleen asked.

Another sound, intense and brief, washed across him. He listened carefully, and then he politely asked to hear it again. “I don’t know the name,” he confessed. “But the words make sense to me.”

“I’m not surprised,” Aasleen allowed.

Alone waited.

“We know what you are,” she promised.

His response, honest and tinged with emotion, was to tell his captor, “I already know what I am. My history barely matters.”

“All right,” Aasleen allowed. “Do I stop talking? Should I keep my explanations to myself?”

He considered the possibility. But machines and teams of engineers were working hard, obviously preparing to do some large job. As long as the woman in the mirrored uniform was speaking, nothing evil would be done to him. So finally, with no doubt in the voice, he said, “Tell me about these Bakers.”

“They built you.”

“Perhaps so,” he allowed.

“Seven hundred million years ago,” Aasleen added. Then a bright smile broke open, and she added, “Which means that you are the second oldest machine that I have ever known.”

The Great Ship being the oldest.

Quietly, with a voice not quite accustomed to lecturing, she explained, “The Bakers were never natural travelers. We don’t know a lot about them, and most of our facts come through tertiary sources. But as far as we can determine, that species didn’t send even one emissary out into the galaxy. Instead of traveling, they built wondrous durable drones and littered an entire arm of the galaxy with them. Their machines were complicated and adaptable, and they were purposefully limited in what they knew about themselves. You see, the Bakers didn’t want to surrender anything about themselves, certainly not to strangers. They were isolated and happy to be that way. But they were also curious, in a fashion, and they could imagine dangerous neighbors wanting to do them harm. That’s why they built what looks to me like an elaborate empty bottle—a bottle designed to suck up ideas and emotions and history and intellectual talents from whatever species happens to come along. And when necessary, those machines could acquire the shape and voice of the locals too.”

Nothing about the story could be refuted. Alone accepted what he heard, but he refused to accept that any of it mattered.

Aasleen continued, explaining, “The Bakers lasted for ten or twelve million years, and then their world’s ecosystem collapsed. They lived at the far end of our galaxy, as humans calculate these measures. The only reason we’ve learned anything about them is that one of our newest resident species have collected quite a few of these old bottles. In partial payment for their ongoing voyage, they’ve shared everything they know about the Bakers. It’s not the kind of knowledge that I chase down for myself. But Washen knew that I’d be interested in dead engineers. And she mentioned just enough that I recognized what was being described, and I interrupted to tell her that I knew where another bottle was, and this one was still working.

“‘Where is it?’ she asked.

“I told her, ‘Wandering inside the Great Ship, he is, and he answers to the very appropriate name of Alone.’”

The captain paused, smiling without appearing happy.

Alone watched the workers. An elaborate needle was being erected on the cavern floor, aiming straight up at him.

“We approached Miocene with our news,” Aasleen continued. “I know Washen was disappointed. But I was given the job of finding you again, and if possible, corralling you. Washen helped me profile your nature. Your powers. I decided to lure you in with the promise of another machine like you, and that’s why I turned Bottom-E into a halfway famous abode for a glowing shape-shifting soul. If something went ugly-wrong down here, then at least the damage could be contained.”

“What about the LoYo?” Alone asked.

“They’ve been moved to other quarters. The lights above are hiding sensors, and I designed them myself, and they didn’t help at all. Until that light show, we couldn’t be certain that you were anywhere near this place.”

The needle was quickly growing longer, reaching for the cage’s outermost wall.

“What will you do now?” Alone asked.

“Strip away your engine, first. And then we’ll secure it and you.” Aasleen tried to describe the process, offering several incomprehensible terms to bolster her expertise. But she seemed uneasy when she said, “Then we’ll isolate your neural net and see what it is and how it works.”

“You are talking about my mind,” Alone complained.

“A mind that lives beside a powerful, unexploded bomb,” the captain added.

“The Bakers didn’t design you to survive for this long. My best guess is that you pushed yourself outside the Milky Way, and in that emptiness, nothing went wrong. You drifted. You waited. I suppose you slept, in a fashion. And then you happened upon the Great Ship, before or after we arrived. You could have been here long before us, but of course the Bakers are lost, and you weren’t what I would consider sentient.”

“But I am now,” he said, his voice small and furious.

Aasleen paused.

Without apparent effort, the needle began to pass through the wall of the first impenetrable cage.

“You are going to kill me,” he insisted.

The human was not entirely happy with these events. It showed in her posture, her face. But she was under orders, and she was confident enough in her skills to say, “I don’t think anything bad will happen. A great deal of research and preparation has been done, and we have an excellent team working on you. Afterwards, I think you’ll prefer having all of your memories pulled loose and set inside safer surroundings.”

With a sudden thrust, the needle pierced the other cages, and before it stopped rising, its bright plasmatic tip was touching his center.

Damage was being done.

Quietly but fiercely, he begged Aasleen, “Stop.”

One of the nearby machines began to wail, the tone ominous and quickening. Aasleen looked at the data for a moment, and then too late, she lifted one of her hands, shouting, “Stop it now. We’ve got the alignment wrong—!”

Then the captain and every engineer vanished.

They were projections, Alone realized. The real humans were tucked inside some safe room, protected from the coming onslaught by distance and thick reaches of enduring hyperfiber.

He was injured and dying. But the damage was specific and still quite narrow, and the faltering mind lay exposed like never before. And that was when the Voice that had always been speaking to him and to every soul that stood upon or inside the deep ancient hull could be heard.

“I am the Ship,” the Voice declared.

“Listen!”

In a place that was not one place, but instead was everywhere, Those-Who-Rule received unwelcome news. There was trouble in Creation, and there was sudden talk of grand failures. A portion of the everywhere was in rebellion. How could this be? Who would be so foolish? Those-Who-Rule were outraged by what they saw as pure treachery. Punishment was essential, and the best punishment had to be delivered instantly, before the rebellion could stretch beyond even their powerful reach. A ship was aimed and set loose, burrowing its way through the newborn universe. When it reach edits target, that ship would deliver a sentence worse than any death. Nonexistence was its weapon—oblivion to All—and with that one talent, plus an insatiable hunger for success, the ship dove on and on until it had passed out of sight.

But then the revenge lay in the past. A moment later, upon reflection, Those Who-Rule questioned the wisdom of their initial decision. Total slaughter seemed harsh, no matter how justified. In a brief discussion that wasted time on blaming one another, these agents of power decided to dispatch a second ship—another vessel full of talents and desires and grand, unborn possibilities.

If the second ship caught the first ship—somewhere out into that mayhem of newborn plasmas and raw, impossible energies—disaster would be averted. Life and existence and death and life born again would remain intact. But the universe was growing rapidly, exploding outwards until two adjacent points might discover themselves separated by a billion light-years.

The chase would be very difficult.

And yet, the second ship’s goal could be no more urgent.

Through the fires of Creation, one ship chased the other, and nothing else mattered, and nothing else done by mortals or immortals could compare to the race that would grant the universe permission to live out its day.

Alone listened to the insistent relentless piercing voice. And then he felt his center leaking, threatening to explode. That was when he interrupted, finally asking, “And which ship are you?”

The Voice hesitated.

“But you can’t be the first ship,” Alone realized. “If you were carrying this nonexistence…then you wouldn’t know about the second ship chasing after you, trying to stop your work…”

In a mutter, the Voice said, “Yes.”

“You must be the second ship,” he said. “What other choice is there?”

“But a third choice exists,” the Voice assured.

“No,” said Alone.

Then in terror, he said, “Yes.”

“I am,” the Great Ship said.

“Both,” Alone blurted. “You’re that first ship bringing Nothingness, and you’re the second ship after it has reached its target.”

“Yes.”

“But you can’t stop the mission, can you?”

“I have tried and cannot, and I will try and nothing will change,” the Great Ship declared. Sad, yet not sad.

“You’re both ships, both pilots.”

“We are.”

“Working for opposite ends.”

“Yes.”

“And the humans are happily, foolishly riding you through their galaxy.”

“Doom everywhere, and every moment ending us.”

Alone felt weak, and an instant later, stronger than he had ever felt before. As his energies flickered, he said, “Tell them. Why can’t you explain it to them?”

“Why won’t they hear me?”

“I hear you.”

“Yes.”

“I could tell them for you.”

“If you survived, you would explain. Yes.”

“But.”

“It is too late.”

Alone said nothing.

The Great Ship continued to talk, repeating that same tale of revenge and the chase, of nonexistence and the faint promise of salvation.

But Alone had stopped listening. He heard nothing more. With just the eye of his mind, he was gazing back across tens of thousands of years, remembering every step, and marveling at how small his life appeared when set against the light of far suns and the deep abyss of Time.
