The corridor narrowed the deeper they ran, compressing until the walls pressed so close that Nero felt as if the Archive itself were trying to force them into a single, suffocating line. The metal scraped his shoulder with every step, cold and unyielding, while Helia's grip remained firm around his forearm, anchoring him as they moved. She didn't loosen it until they burst into a junction where the passage split cleanly into three identical paths.
Helia stopped so abruptly that Nero nearly collided with her back.
"Three ways," he panted, lungs burning as he fought to catch his breath. "Which one?"
"None," she whispered.
He frowned, confusion cutting through the exhaustion. "What do you mean—"
"Quiet."
She released him and dropped to one knee, pressing two fingers to the floor. Nero followed her gaze, noticing what she saw only a heartbeat later. The dust wasn't evenly settled. It was disturbed—dragged into shallow arcs and smeared patterns, as if something massive had passed through recently, heavy enough to leave its mark but careful enough not to tear the corridor apart.
The memory of the drone's message surfaced unbidden in Nero's mind.
RUN.
He glanced down each corridor. The lights flickered in uneven rhythms, each passage pulsing differently, like the Archive itself was breathing through them, waiting to see which path they would choose.
Helia rose slowly. "We're not taking a direction the Archive offers."
Nero blinked. "Then where—"
She pointed upward.
He followed her gesture to the ceiling. A cracked maintenance hatch clung there by a single rusted bolt, dust shaking loose every time the lights flickered.
"We go up," Helia said.
Nero stared at it, disbelief cutting through his fear. "That thing looks like it'll fall apart if we breathe on it."
Her mouth twitched—something that might have been a smile, or maybe just fatigue tugging at her expression. "Good. If it collapses, the Archive won't assume anyone climbed through it."
She stepped closer to him. "Boost me."
Nero didn't argue. He laced his fingers together and lifted. Helia vaulted smoothly, catching the hatch with both hands. The metal shrieked in protest, but she didn't hesitate. She shoved it open and pulled herself through.
"Your turn," she whispered.
Nero jumped, fingers slipping once before catching the edge. Helia's hand closed around his wrist, tighter than strictly necessary, and she hauled him up with surprising strength. The hatch clanged shut beneath them, sealing off the corridor below.
They were inside a narrow maintenance crawlspace, barely high enough to crouch. Helia moved ahead on her knees and elbows, her silhouette framed by faint blue light leaking up through gaps in the metal. Nero followed, the sound of their breathing filling the confined space.
After a few minutes, he whispered, "Helia?"
She didn't stop crawling, but her voice softened. "Hm?"
"That drone," he said quietly. "Do you think someone sent it?"
Her movements slowed for a fraction of a second. "Maybe."
"But who?" Nero pressed. "A survivor? A rebel? Another prototype? The echo?"
She resumed her pace. "It doesn't matter who."
"Then what matters?"
Her reply was barely audible. "Why."
Nero swallowed. "Why, then?"
"To warn you."
A cold knot tightened in his chest. "About what?"
"About what's coming."
They crawled in silence after that until Helia pushed open another loose panel. Warm light spilled into the crawlspace, and she motioned for Nero to follow. He slid out after her—and froze.
They stood in a massive circular chamber unlike anything they had seen so far. The walls curved upward, covered in flickering holographic lines of damaged code, teal and white patterns stuttering like corrupted constellations. The ceiling hummed with low energy, bathing the space in a gentle glow.
It didn't look abandoned.It didn't look broken.
It looked forgotten.
Helia's eyes widened. "This isn't on any map."
Nero stepped forward, drawn in despite himself. Glass-like panels ringed the chamber, each one displaying faint, ghostly shapes—blurred figures, fractured silhouettes that flickered in and out of coherence.
"What is this place?" he whispered.
Helia exhaled slowly. "Sector L-Zero."
"You know it?"
"No," she said. "That's the problem. I've only heard whispers. The rebels called it the sector that shouldn't exist."
Nero's gaze locked onto one of the panels. A small face flickered there—distorted, frightened, eyes wide with a terror he knew too well.
Prototype Eleven.
His chest tightened painfully. Around the chamber, similar echoes appeared and vanished, fragments of lives that no longer existed in this timeline.
"This… this is them," Nero said hoarsely.
Helia didn't deny it. She moved to the panel showing Prototype Eleven and lifted her hand, stopping just short of touching the surface. Her fingers trembled.
"I used to escort failed prototypes to reset chambers," she whispered. "I thought they vanished because the Architect erased their data."
Her jaw tightened. "I never imagined their timelines lived on like this."
"You didn't know," Nero said quietly.
"I didn't want to," she replied, and the guilt in her voice was unmistakable.
The light in the chamber shifted suddenly, rippling like water disturbed by a dropped stone. Nero stepped back instinctively as Helia raised her weapon.
"What now?" she muttered.
A low hum rose from the center of the room. A pillar of light materialized, swirling with static. Within it, a silhouette formed—tall, broad-shouldered, its edges glitching violently.
Not the Architect.Not a prototype.Not a machine.
Something else.
Helia whispered, "Back up."
Nero didn't move.
The figure lifted its head slowly, and even through the distortion, something struck deep in Nero's chest—a sensation both warm and painful, familiar in a way that made his breath catch.
"Nero," Helia warned.
He stepped forward anyway.
The figure's face remained blurred, as if the Archive itself were trying to hide it, but its voice cut through the distortion, steady and sharp.
"You survived."
Nero's heart slammed against his ribs. He knew that voice—buried beneath erased memories, beneath the pod, beneath everything.
Helia stepped between them, weapon raised. "Identify yourself."
The figure ignored her. "Prototype Twelve," it said softly, with something dangerously close to emotion. "I told you… if anything went wrong… follow the echoes."
"I know you," Nero whispered.
The figure flickered violently. "You will," it replied. "Soon."
Helia glanced at Nero sharply. "Energy levels are spiking. Something's wrong."
"Who are you?" Nero demanded.
The figure lifted a glitching hand, almost reaching for him. "Find me before the Architect does."
The chamber erupted in white light. Helia tackled Nero as a shockwave tore through the room. Panels shattered. Echoes screamed before dissolving into streams of light. The figure disintegrated, the pillar collapsing into nothing.
Silence followed.
Helia's breathing was ragged. "Nero… what was that?"
He stared at the fading particles drifting down like dust. "I don't know."
But his chest ached with the certainty of it.
He had known that voice before the wipe. Before the pod. Before the Archive.
Someone important.Someone erased on purpose.
Helia grabbed his shoulder. "Stay with me."
He nodded, eyes never leaving the empty space. "He said… find him."
"We will," Helia said quietly.
The lights flickered once—then died.
In the darkness, Nero whispered, "I think I know why the Archive wants me erased."
Helia didn't ask.
Because she already knew.
