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.”
