Chapter 16: Protocol Null

WOOOOOOOOO—

The alarm blared so loud it hurt. Lights flashed. Panels ripped themselves open. The ceiling convulsed like the train itself was panicking.

A mechanical voice cut through the chaos:

"Protocol Null Initiated. System reboot in 120 seconds. All anomaly traces will be purged."

"What the hell is Protocol Null?!" Sunny yelled, grabbing onto a support beam as the train began to twist unnaturally.

Neith's fingers danced across her wristboard, sweat beading on her forehead. "It's the final fail-safe. When the system detects a causality breach—like you interacting with whatever that was—it wipes the entire chain. The memories, the people, the records. Everything."

"Wipes us?!"

"Yes."

Outside the train, the void began to crumble. Not metaphorically—it pixelated, fracturing like corrupted code. In its place, raw data bled through, lightning arcs of blue and red code winding through the collapsing blackness.

Sunny clenched his fists. "How do we stop it?"

"We can override it. But there's only one place with the right command interface." She paused. "The Engineer's Car."

He turned toward the far end of the train—the door sealed with thirteen locks and a radiation warning. No one had ever opened it. Not even Neith.

"That car's been locked since the first jump," she said.

Sunny stepped forward.

"Well, it's time someone knocked."
