Silence kept its own weight in the chamber.
After the explosion of white-light and the origin node’s bloom, the world did not resume its ordinary hum. It held a low, metallic thrum—so faint it might have been imagined, except the floor registered it. Riven pushed himself up on an elbow and saw the thing before he needed a name for it.
It stood a few meters away, not a beast, not machinery: an arc carved of light and dark metal, a segmented curve that rose like a living glyph. It did not move in the hurry of predators. It moved in the patient way of someone choosing the right word.
Idris lay on the floor beside him, eyes open but not looking. Sweat clung to his temple. Calyx was already on his feet, scanning, weapon lowered but ready—an officer who had learned when to wait.
The arc blinked once: short-long-short. Riven felt the pattern like a palm on his back—a call-sign they had seen before, and now the syntax changed.
Idris made a sound—half-voice, half-memory. “Witness,” he whispered. The word trailed like a thread, and Riven watched it catch on the laminated air between them.
Calyx crouched, rolling a small handheld lamp between his fingers. He flicked it to a medium beam and, with a decision that felt like a test, tossed it gently toward the arc. The object hung in the air for a beat, then the arc bent through it—light bowed, folded, and the lamp drifted back toward Calyx hands-first, untouched.
“That’s not aggression,” Riven said. “It’s showing restraint.”
Calyx’s answer was a look. “It’s testing.”
Riven pushed himself to his feet. He pulled the portable console he’d thought to bring—primitive, jury-rigged, enough to throw a question into whatever interface this was. He tapped a simple string: WHO ARE YOU?
The console responded with a lag, a warble—then a blink of characters across its small screen: A—WIT— and then the line corrupted. The letters derailed into static, as if someone had cut the signal with a pair of shears.
Riven let out a breath he hadn’t known he was holding. The half-phrase had the smell of protocol about it. Not creature-thought; architecture thinking.
Idris shivered. He rose on his elbows and looked at them both with the soft panic of someone who can feel a page turning in his head and cannot reach it. “It said… it said something. Not fully. Just a fragment. ‘Witness…’” His voice was not his own, or perhaps it had been borrowed.
The arc slotted itself into a new position then, folding a segment inward until it mimicked the angle of Riven’s shoulders. In the blink of a breath, the curve arranged a shadow that resembled him—no face, only outline—and the air around it hummed as if recognizing the pattern. For a sliver of a moment Riven felt something like being seen: not by a camera or by data, but by an entity measuring pattern against pattern.
His chest tightened. “It— it’s making me into something.”
Calyx moved closer, hand flat on Riven’s forearm. “Step back. If it’s trying to do that—don’t let it.”
Idris’s eyes unfocused. He started to speak, voice thin: “Anchor… anchor—Hale?” The syllables came like pebbles thrown into deep water. In the echo a second sound replied: a metallic cadence, like a mechanical voice failing its sentence: “…must—choose…”
Riven’s fingers twitched over the console. He forced himself to be methodological. Protocol-first. Question-second. The console offered no answers, only more fragments: ?—HALE—ANCHOR? The letters scrolled and stuttered, as if someone—or something—was trying to translate a name into logic.
“Why the name?” Riven asked aloud, though he knew. He felt a hollow recognition at the name Hale, like a photograph of himself taken at a different angle. It meant that whatever the node had once indexed, it had used human patterns to shape its memory: names, forms, signatures. It had found a slot it thought fit him.
The arc inclined, and a filament of light ran the length of its curve—thin, electric, and precise. It traced Riven’s sleeve, paused at the seam of his glove, and sent a tiny, clean shock into his skin; not painful, only a punctuation. Riven staggered but did not fall. Musicless, it had read him.
He felt something flash across his mind: Hale’s hand on the core, the shadow of a camera in front of a face; a whisper—“It opens because…”—and then a cutting silence. The memory was half-given and the rest demanded completion.
Idris’s lips moved again. “Anchor,” he said, clearer this time. “It wants—anchor.”
Calyx’s eyes hardened. “It’s trying to ask for a witness.”
“No,” Riven said. The word left him as a warning to himself. “It’s trying to find one that can make the event hold. It’s not hunting us to destroy us. It’s searching for a slot to fit the past into present.”
Light warped across the arc; the curve seemed suddenly impatient. The console that Riven held blinked a final fragment: A—WIT—? HALE? The question mark looked like a plea.
Another sound—the scratch of metal over metal—issued from the far side of the chamber. It was the entity’s signature moving away, a departure and a return folded together. Then, impossibly, it stepped back, arranging its shadow like a constable closing a book.
Idris sagged to his knees, breath rushing. “I hear voices now—protocol. Not like before. They say: choose or be chosen.”
Riven swallowed. The phrase slipped into his bones. The room’s pulse went sharper; a faint indicator on the node’s rim glowed—43—thin and ephemeral.
Calyx tugged at Riven’s sleeve. “We can’t let it make a choice for us. We walk away. We cut the node. We report it.”
“And do what?” Riven asked. “Watch them wipe the site clean and leave the memory incomplete? Or hand it a different anchor—a name—so it stabilizes? Either way we become instruments.”
The arc hummed, as if listening.
For a moment every element held its breath: the men, the curve, the node. Then, as if to emphasize the point, the arc peeled one small shard of light from its body and set it on the floor—an afterimage shaped like a crescent. It did not glow long. It was a signature left behind, a token.
Riven stared at the shard. It was a small half-ring shape, faint and perfect.
“You see that?” Calyx murmured.
Riven nodded. He understood in the way of a man who learns, too late, that a mirror is not just a reflection.
The arc inclined one last time—passive, like a bow—and drifted backwards into the deeper dark of the chamber. When the glow blotted out, Idris spoke in a voice that might have been from the node itself: “A witness chooses or is chosen.”
The words settled around them like dust.
Riven pocketed the shard without thinking.
They did not move immediately. Outside, some part of the station kept its distance. Inside, something had opened its eye.
And somewhere down the line, a protocol began to wait.
