Read Chapter 30: Inside the Machine

The maintenance corridor smelled of recycled air and hot lubricant. Fluorescent panels buzzed overhead, casting everything in a flat, sterile white. Caleb moved at a half-crouch, Lena a step behind him, Grendel's hand-drawn maps unfolded in her grip.

"This way," she whispered, tapping a faded pencil mark. "Past the waste chute, then up the service ladder."

"You've memorized it," Caleb said.

"My father drew it. I traced every line until it burned into my head."

Caleb didn't press further. Grendel's name hung between them like a held breath, neither willing to break it. The corridor dead-ended at a rusted ladder bolted to the wall. Lena climbed first, boots silent on the rungs. Caleb followed, the shriek of a distant alarm filtering down from somewhere above.

The detention level was exactly where Amara had said it would be. Sublevel three, tucked beneath the corporate archives where no one who mattered would ever look. But between them and the blast door stood the checkpoint.

Two Helix guards, standard-issue carbines slung, stationed in front of a iris scanner. Behind them, a reinforced gate that would take a breaching charge and a half-hour of cutting to open. The gate itself was the obstacle. The guards were the confirmation.

Caleb pulled Lena back into the shadow of a maintenance access alcove. "My father helped design the secondary power system down here," he murmured. "That means he left a bypass."

"Where?"

"The cargo drones. They route through the structural veins of the building to avoid hauling anything through the corporate floors. If I can reach the drone dispatch terminal, I can override one."

Lena studied his face, searching for something. Finding it, she nodded. "I'll watch your back."

He worked her through the junction box, popping the cover with a multitool, revealing a flickering data port meant for service technicians. He jacked in his salvaged terminal, running old Helix credentials through memorized command strings. The first pass failed. The second too. His father had taught him something about Helix's security philosophy: time locks that reset on failed attempts, but doors that always opened for certain freight.

"There," he breathed.

A cargo drone, six hundred kilos of unprocessed regolith destined for a construction site on the surface, rerouted from its schedule. He gave it a false collision vector. Three seconds later, the drone lurched off its magnetic rail three floors up and slammed into a wall junction box. The decompression alarm screamed through the building. Red emergency lighting flooded the corridor.

The guards exchanged a glance. One tapped his earpiece, barked something inaudible, and both sprinted toward the source of the chaos.

"Now," Caleb said.

They crossed the checkpoint in seconds. Lena swiped her father's engineered keycard at the iris scanner, and the gate clunked open wide enough for them to slip through. The detention wing smelled of disinfectant and recycled nitrogen. Rows of identical cells lined the corridor, each with a small window of reinforced glass.

Mei Lin was in the fifth cell on the left.

She sat upright on a narrow cot, hair loose, wearing a plain gray jumpsuit. She was thin but not gaunt. Bruises darkened her knuckles, and a thin cut traced her left cheekbone. But her eyes were sharp, watchful, and they found Caleb the moment he reached the glass.

"You have your father's jaw," she said. Voice steady. Unbroken.

"You have my mother's blood," Caleb said. "That's what I'm here for."

Mei Lin rose slowly, crossed the cell, pressed her palm flat against the reinforced partition. "Naomi is awake?"

"She's on a shuttle with Amara. She's dying. Her chip needs your biometric key to unlock the archive. Fresh blood, old Helix protocol."

Mei Lin's expression flickered. Something cold passed behind those eyes. "They froze her too. All those years."

"Grendel's daughter helped me get in," Caleb said. "We're not leaving without you."

Mei Lin glanced at Lena, a long unreadable look. Then she nodded. "He always said you'd come for me. The old fool. He prepared better than Helix ever expected." She tapped the glass. "My cell door is keyed to a supervisor's palm print, not a code. You're going to need to bypass the controller on the wall."

Lena was already at the panel, Grendel's maps scattered around her feet. "The controller's encrypted. I can brute-force it, but it'll take an hour and trip a silent alarm."

Caleb knelt beside her. "We don't have an hour."

"Then you find me another way."

He studied the panel. Helix's designs were modular, built on legacy architecture that predated their colonial charter. His father had helped integrate those systems. And his father had left him a map no one else knew existed.

"There's a maintenance override," he said, tapping a recessed keyhole above the panel. "Dad's signature runs through the secondary power system. It's supposed to be accessible only to chief engineers."

Lena raised an eyebrow. "You're a salvage specialist."

"I'm also his son."

He pulled out the chronometer. Broken, dormant, its face cracked but its internal mechanism intact. He pried off the back casing, exposing a data core he'd never fully understood. His father had embedded a micro-connector in the design. An old-fashioned master key.

He slotted the chronometer into the override port. A click. A whirr. The cell door hissed open.

Mei Lin stepped out. She looked at the broken device in Caleb's hands, then up at his face. "Your father built that before they killed him. He knew this day would come. He told me the night we fought over the first Exodus records: 'If my son ever comes, trust him with everything. But don't let him trust the machine.'"

"What does that mean?"

Mei Lin's mouth tightened. "Helix has a dead-man's switch. I helped design it, back when I believed in their vision. If certain individuals are alerted—the CEO, the board president, anyone with a high-tier access card—the system purges every digital record in this facility. Every log, every file, every bit of evidence buried deeper than a terraform drill can reach. Your mother's archive would cease to exist."

"How do we stop it?"

"We don't." Mei Lin touched the chronometer in his hand. "We beat it. The purge is algorithmic. It runs through a specific sequence of legacy subsystems, all routed through the central mainframe. If we can disable the mainframe's purge sequence before it engages, the switch fails."

"Then we need to reach the mainframe, not run."

Lena looked up from her maps. "Mainframe's two levels up, in the server core. Most heavily guarded space in the building besides the vault."

Caleb looked at the chronometer, its cracked face, the dormant internal mechanism. His father's voice whispered in his memory: *Trust everything. Trust nothing.*

"Then we go there," he said. "Together. And we turn that switch into a paperweight."

Mei Lin smiled, and for the first time, he saw something like hope in it. "You are your father's son."

Behind them, the corridor echoed with the sound of boots on metal. Too many to be the two guards he'd sent running.

Caleb glanced at Lena. She was already folding the maps, sliding them into her jacket. "I know the way," she said. "But we need to move now."

"Then move," Mei Lin said. "And pray that dead-man's switch is slow."
