Read Chapter 13: Aftermath of Fire

The transport’s engine coughed twice before dying completely as Caleb rolled it to a stop inside the base’s service bay. The heavy blast doors ground shut behind him, sealing out the thin Martian night and, with any luck, the eyes that had tried to kill him twice in the last six hours.

He sat there for a moment, hands still gripping the controls, knuckles white beneath the grime and dried blood. His shoulder throbbed in a steady, angry rhythm. The explosion had thrown him hard against the rover’s frame, and the makeshift bandage he’d tied an hour ago was already soaked through.

He let go of the controls. Flexed his fingers. Breathed.

The bay was dark except for the emergency strips along the floor, casting everything in a pale amber glow. His father’s base hummed around him—the ever-present whisper of recycled air, the distant groan of metal settling against the cold. Familiar. Almost welcoming.

Caleb hauled himself out of the transport and immediately regretted it. The movement sent a spike of pain through his shoulder and down his arm. He braced against the hull until the world stopped tilting, then forced himself toward the interior lock.

He moved through the corridors on memory, his footsteps echoing too loud in the silence. The control center was where he’d left it—screens dark, the hidden panel still ajar where it had slid open days ago, revealing the stone corridor that led to his father’s secrets. He didn’t go that way now. Instead, he keyed open a maintenance closet near the rear of the facility and pulled out the med kit his father had always kept stocked.

The seal was intact. The contents were older than Caleb himself, but the antiseptic and wound sealant still looked viable. He stripped off his jacket and shirt, wincing as the fabric pulled at the gash across his shoulder. The blast had sent shrapnel deep enough to leave a ragged tear, but the bone felt solid. He cleaned the wound with shaking hands, poured the sealant into the gap, and held his breath as it foamed and hardened into a rough patch over the flesh.

It would hold. It had to hold.

He found a fresh shirt in a storage locker—his father’s, too large in the shoulders—and pulled it on. Then he sat on the edge of a workbench, let his head hang forward, and tried to think.

Helix had tried to kill him. Not just scare him, not just warn him. The bomb had been placed with precision, timed to catch him as he climbed into his rover. If he’d opened the door a second earlier, he wouldn’t have had time to roll clear. The transport he’d salvaged had no registration, no transponder linking it to the Voss name. That was something.

But the base itself was the problem. His father had built it as a hidden refuge, but Helix knew where it was. They’d known where he was going before he’d told anyone. Which meant they either had surveillance in the area, or they’d tracked him from the moment he left New Houston.

He stood and walked to the main console. He pulled up the facility’s transmitter logs, scanning for any irregular pings, any unexpected handshakes with external networks. Nothing. The base was quiet. But quiet didn’t mean invisible. If Helix knew this location, they could send a drone in the next few hours. They could bury him here without a trace.

He was still staring at the screen when his gaze drifted to a schematic he hadn’t noticed before. A maintenance diagram, tucked into the submenu of the base’s original construction files. There was a section labeled only as a shielded storage annex, marked with a symbol he’d learned in his first year of salvage work: lead-lined. Transmission-proof.

He traced the diagram with his finger. The annex was small, no more than four meters square, buried beneath the eastern wing of the facility. His father had never mentioned it. But then again, his father had never mentioned a lot of things.

It took him twenty minutes to find the access panel. It was hidden behind a false bulkhead in what he’d always assumed was a solid wall. Inside, the space was cramped and dark, the air stale and cold. A single cot. A small desk. Racks of supplies that looked untouched. And in the corner, a series of lead-lined cabinets that would block any signal from leaving or entering.

Caleb pulled the door shut behind him. The seal engaged with a soft hiss, and suddenly the world went very quiet. He could feel the difference immediately—that constant low-level buzz of the base’s transmissions was gone. Even his own suit radio, still active on his belt, showed no signal.

He exhaled. For the first time since the explosion, his body unclenched by a fraction.

He sat on the cot, the springs groaning under his weight, and pulled the chronometer from his pocket. His father’s chronometer. The one that had never worked. The one that had reacted when Helix was near.

He turned it over in his hands. The casing was worn, the metal soft from decades of handling. He’d tried to open it before, years ago, but the seams had been sealed tight. Now, with the pressure of his thumb against the back plate, he felt something give.

A catch. A tiny, hidden release.

He pried it open with the edge of his knife, and the casing split cleanly along a seam he’d never seen. Inside, the mechanism was unlike anything he’d expected. There were no gears for keeping time—no springs, no escapement, no balance wheel. Instead, the interior held a dense arrangement of micro-etched plates, layered like the pages of a book, each one covered in patterns so fine they seemed to shimmer under the light.

He tilted it, catching the glow from the desk lamp. The plates caught the light and threw it back in a constellation of tiny dots—points of reflection laid out in a pattern that wasn’t random. He knew star charts. He’d grown up with the night sky of Mars, a different sky than Earth, but a sky he knew intimately.

This wasn’t a sky above him.

He moved to the desk, set the chronometer down, and angled the lamp directly over it. The reflections sharpened, forming a cluster of points that echoed a layout he’d seen on the base schematics. Not stars. Rooms. Corridors. A map etched in micro-optics, meant to be read by light, not hands.

He pulled up the base layout on the desk’s small display and began matching the points. One by one, they fell into place. The control center. The stone corridor. The hidden lab. And there—a point that sat in a section of the map that was blank, a void where no room was marked. The interior of the chronometer was not just a map. It was a key. And the lock was a room that wasn't supposed to exist.

Caleb sat back, the chronometer cradled in his palm. His shoulder ached. His body was tired in a way that went beyond exhaustion. But his mind was sharp, sharp as the edges of the plates he’d just exposed.

His father had left this in his will. Had made it the centerpiece of a legal battle that spanned a decade. And now, in a lead-lined room beneath a hidden base on Mars, Caleb held what Elias Voss had died to protect.

He scanned the coordinates on the map one more time, correlating them with the base’s internal grid. The void was directly behind the vaulted power cell casing in the deepest part of the facility—a location that would only become accessible if you knew which false wall to move and which sequence to key into the secondary power panel.

He had the map. He had the sequence. It was all here, in the silent language of a dead man’s clock.

He should rest. He knew he should rest; his body was demanding it. But the room was calling to him, quiet and close, and the truth was just behind a false wall.

Caleb rose, pocketed the chronometer, and walked out into the corridor. The lead-lined door sealed behind him, and the base’s hum returned, faint and familiar. He moved through the dark toward the deepest part of the facility, his footsteps echoing in the quiet.

The map was clear in his mind, the points blazing like a constellation. Where his father’s path had ended, his own was beginning.
