Read Chapter 6: A Debt to Helix

The control center hummed around Caleb like a living thing. He had been sitting in the same chair for what felt like hours, staring at the bank of translucent displays that curved across the far wall. The orbital feeds flickered, showing Earth and Mars in their slow cosmic dance—positions that should have been impossible three years before the colony's founding.

He pushed back from the console and rubbed his eyes. The data storage array hummed beside him, a squat black monolith etched with symbols he didn't recognize. His father had left it unlocked, as if expecting him to find it. Caleb reached out and tapped the activation node.

The screen bloomed to life. No password prompt, no encryption key. Just a directory tree, organized by year, stretching back over four decades. Folders labeled with dates, some with names. He recognized his father's handwriting in the file structure—the same slanted letters he'd seen on engineering schematics and birthday cards.

The earliest folder caught his eye. *Orbital Debris, 2135.* That was the year of the Helix buyout, the year the corporation took over the failing colony infrastructure and re-branded it as a fresh start. Official history said Helix arrived in response to a distress call from Earth—a rescue mission that evolved into the founding of the settlement.

Caleb opened the folder and felt his stomach drop.

It wasn't technical data. It was a ledger.

Long rows of numbers marched across the screen, documenting resources extracted from a site identified only as *PD-07*. Plasma conduits. Fuel cells. Atmospheric processors. The quantities were staggering—enough material to build a second habitat complex. And at the bottom of every entry, a single name: **AARON VOSS**.

His father.

Caleb scrolled deeper. The ledger wasn't just a record of extraction. It was a debt schedule. Helix had fronted Aaron Voss enormous credit lines, documented in the corporation's own accounting system, marked against a project code that came up as gibberish until Caleb deciphered it: *TERRAFORM SPEARHEAD, PHASE ONE*.

He pulled up the project description and sat back, the glow of the screen painting his face in cold blue light. His father had signed for advanced fusion cores. For biological containment units. For a fabrication plant's entire output capacity across two Martian years.

Caleb had known his father was ambitious. The man had always been chasing something bigger than a maintenance contract, bigger than the small salvage operation he'd run from the Rust Belt. But this was something else. This was a scale of borrowing that would have been financial suicide without collateral.

Unless the collateral was the secret itself.

He flipped to the final page of the ledger. Beneath the debt total—a number that made Caleb's lungs tighten—was a single line of annotation in his father's handwriting, scanned into the file:

*The cost of silence is never settled in cash. They'll want more. They always want more.*

Caleb stood, pacing the length of the control center. The glass walls reflected his silhouette against the garden beyond, the impossible green of the plants swaying in artificial air currents. His father had built this place, or funded it, or hidden it—all questions he still couldn't answer. But the debt explained something else.

The operative who had followed him in New Houston. The eyes on the colony's streets. Helix wasn't just protecting a corporate secret. They were protecting an investment.

A chime sounded from the far end of the room. Caleb turned, every nerve firing. His rover's comm unit, mounted on the wall where he'd plugged it in to charge, was blinking with an incoming transmission.

His blood went cold. The rover's comm band was short-range, designed for desert expeditions, not orbital relays. A message shouldn't have been able to reach him down here beneath a hundred meters of regolith and glass.

Unless whoever sent it had been tracking his position since before he'd entered the structure.

He crossed to the comm and hit the receive key. The screen flickered, static chewing at the edges of a familiar corporate logo—the sharp hexagonal helix that symbolised the corporation's grip on every settlement on Mars.

A voice came through, synthesized and emotionless:

*"Message for Caleb Voss. Serial number 3412-RB. This is an official notice from Helix Corporate Counsel. You are hereby ordered to cease all unauthorized exploration of restricted territory in Acidalia Planitia. Your current location has been flagged as a violation of Settlement Accords Article 12, Section B, pertaining to unlicensed salvage operations in designated exclusion zones. Continued activity will result in legal action, including—"*

The transmission cut off mid-sentence, replaced by a burst of static, then a second signal. This one wasn't synthesized. The voice was older, rougher, carrying the crackle of a poorly maintained relay.

*"Caleb."*

He froze. That voice. He hadn't heard it in over a decade, but it was seared into his memory like a brand.

*"Caleb, if you're hearing this, you found the base. Good. The records are incomplete. There's more—but you're going to have to go deeper, past Meridian, to the place where the sky was never seen."* There was a pause, the sound of breath under pressure. *"Don't trust the first story. Don't trust the second story. Trust the chronometer. Trust what it points at when you stop moving."*

The transmission ended with a click, and the comm went dark.

Caleb stood in the silence, his father's words ringing in his ears. *Past Meridian.* There was another location. Another hidden truth.

And Helix knew where he was.

He turned back to the ledger, staring at his father's debt, at the project codes, at the implication that the corporation had financed something so secret that they'd buried it beneath the northern plains. If they were watching his rover, they'd been watching from the moment he crossed the desert. The operative in New Houston must have planted a tracker.

A cold calculation settled in his chest. They knew where he was, but they hadn't come to stop him physically. They were trying to scare him off with legal language and corporate procedure. That meant they didn't know what he'd already found. Or they didn't want to risk a confrontation in a space they didn't control.

Either way, he had time.

He reached down and pulled the chronometer from his pocket. The broken timepiece sat in his palm, its hands frozen in that downward angle. He turned slowly, watching the hands move relative to his position, until they aligned with a point in the wall behind the main console.

A point that led deeper into the base, past the garden, past the housing units, toward a door he'd noticed earlier—a door marked only with the number 07.

Caleb pocketed the chronometer and started walking. He would find what his father had hidden. He would understand the debt, the base, the lie at the heart of the colony. And then he'd settle the account—whether Helix liked it or not.
