Read Chapter 18: The Internal Enemy

The smoke tasted like burnt copper and old wiring. Kaelen’s ears rang with a high, thin whine that drowned the screams around him—but he could see Maris ahead, her silhouette sharp against the flickering emergency lights of Deck 1’s main corridor. She was moving, and that meant the door was close.

Another guard collapsed from a ricochet, clutching his shoulder. The loyalists had fought hard, harder than the rebels expected, but they’d been pushed back deck by deck, corridor by corridor. The Circle’s security forces were bred for ceremony, not combat. The maintenance workers and cryo-crew who now formed Kaelen’s vanguard had spent their lives in the guts of the ship, knowing every crawlspace, every vent, every trick of gravity and pressure. They fought like the ship itself was their weapon.

Kaelen ducked behind a support strut, his breather mask fogging with each ragged exhale. Two rebels ahead of him—he knew them by their grime-stained coveralls, not their faces—dragged a third into the shadow of a junction box. The third one wasn’t moving. Kaelen turned away. There was no time for names he hadn’t learned.

“Voss!” Maris’ voice cut through the whine. “Door’s sealed. Need your hands.”

He ran, crouched low, avoiding the worst of the crossfire. The door to the command nexus stood six meters tall, its surface polished obsidian and bronze, the kind of ornate fortress architecture the Circle commissioned to remind everyone below of their place. Sealed, yes. His eyes traced the seams, the lock housing, the emergency override plate that was welded shut. But this was still a ship. Every door, no matter how grand, had a maintenance access point. He just had to find it.

“Give me sixty seconds,” he said, pulling his toolkit from his belt.

The firefight raged behind him as he worked, her fingers finding the access panel behind a decorative rivet pattern. Inside was a mess of wires and a small circuit board the size of his palm. He spliced, bypassed, and shorted in a sequence that felt like muscle memory from a thousand lower-deck repair jobs. The door’s hydraulics whined, then groaned, then began to slide open with a sound like grinding stone.

Maris was through the gap before it was fully open, her rifle raised. Kaelen followed, and the command nexus opened up around them—a vast, circular chamber bathed in the soft blue glow of a dozen holographic displays. It was empty. No guards. No Cassian. No captain at the helm. Just a single solitary figure standing at the central console, head bowed, hands folded in front of her.

The Archivist.

She looked up as they entered, her face pale and ancient, her eyes holding the kind of exhaustion that had nothing to do with sleep. The official memory of the ship lived in her skull—every record, every law, every narrative the Circle had shaped over generations. And she was smiling.

“You’re too late,” she said softly. “He released it.”

Kaelen’s blood turned to ice. “Released what?”

The Archivist gestured to a secondary screen. A schematic of the ship, deck by deck, with a red bloom spreading from the environmental systems like a flower opening in time-lapse. He knew that pattern. He’d seen the simulations. He’d spent years unaware it even existed until he found the log fragments, until Jena told him, until the Vesper sample became a whispered nightmare in the lower decks.

“The plague,” Kaelen breathed.

“A diluted version,” the Archivist corrected, her tone almost kind. “Enough to sicken, not to kill. Enough to make the lower decks very, very afraid. Cassian didn’t want to destroy the ship. He wanted to remind you who controls it.”

Maris raised her rifle. “Where is he?”

“Gone. He and the Circle have withdrawn to the outer habitation rings. They’ll wait out the chaos, then return to restore order. And they’ll be hailed as saviors, because they’ll have the cure.”

Kaelen stared at the spreading red bloom. It was all over the lower decks now, seeping through the ventilation systems, the water recyclers, the shared air. His people—the ones who’d barricaded the lifts, who’d fought alongside him, who’d cheered the broadcast and believed in the truth—were coughing and feverish while he stood in the clean, filtered air of Deck 1.

“How long?” he asked.

“Symptoms in hours. Serious complications in a day. Deaths in three, if untreated.” The Archivist tilted her head. “But you’re the clever one, aren’t you, Kaelen Voss? The one who fixed the water diverters, who found the emergency access points, who knows where every valve and filter in this ship lives. Maybe you can fix this too.”

He wanted to hit her. He wanted to scream. But Maris’ hand was on his arm, firm and steady.

“Kaelen. The bridge is secure. Let’s make it count.”

He forced himself to breathe, to think. The nexus was theirs. They could broadcast again, raise the other decks, solidify the rebellion. But no one would listen if they were dying. No one would care about the truth of the ship’s arrival on a distant planet if they couldn’t draw a breath without pain.

“We need to quarantine,” he said, the words tasting like ash. “Everyone who was on the lower decks. Maris, you take the advance. Get word to the med-bays on Decks 4 and 5—if the contamination hasn’t reached them, they can set up clean zones. I’ll try to trace the release points, see if we can contain it.”

“You’ll be going into the worst of it,” Maris said.

“I know.”

She studied him for a long moment. There was something in her eyes he hadn’t seen before—not calculation, not distance, but something close to pain. She reached out and touched his jaw, just once, a gesture so brief he almost missed it.

“Don’t die,” she said. “The ship needs you.”

“The ship needs a lot of people,” he replied. “I’m just one of them.”

Maris turned and began barking orders to the rebels who had flooded into the nexus. They moved with purpose, securing terminals and communication lines, establishing a defensive perimeter. Kaelen watched her for a moment, this woman who had saved him from execution and staged a mutiny for his sake, who had vouched for his long-lost sister and now led his forces to the heart of the ship. He still didn’t know where her loyalty truly lay. He might never know. But in this moment, she was the only thing moving that felt like hope.

He left the nexus alone, descending through the ship’s spine toward the lower decks. Each level he passed felt more oppressive, the air thicker, the silence heavier. By the time he reached Deck 12, he could hear it—a low, wet chorus of coughing, like a wave breaking against the hull. He pulled his breather mask from his belt and secured it over his face, but it was a flimsy barrier, designed for dust and fumes, not pathogens.

The medical bay on Deck 12 was overwhelmed. Makeshift beds lined the corridors, patients laid out on stretchers and pallets, their faces flushed, their eyes glassy. A medic—a young woman whose name he knew only as Tessa, who’d worked with the cryo-crew—grabbed his arm as he passed.

“Kaelen, thank the stars. We need more supplies. Filters, antivirals, anything.”

“I’ll see what I can find,” he said. “Where’s it worst?”

“Deck 15. The water recycler feeds there first. The ones who took the earliest exposure are already turning blue around the lips. I’ve isolated them as best I can, but there’s not enough—there’s never enough—” Her voice cracked, and she turned away, wiping her face with a gloved hand.

Kaelen wanted to say something reassuring. He wanted to tell her that Maris was pushing forward, that the bridge was theirs, that the Circle’s reign was ending. But those words felt hollow in the face of what he saw around him. A child—no older than ten, his coveralls two sizes too big—sat propped against a wall, his tiny chest rising and falling in shallow gasps. His mother knelt beside him, whispering something Kaelen couldn’t hear.

He looked away.

The real battle was not for the Bridge, he realized. It was for this—for the trust of people who had followed him into the fire, only to find themselves breathing poison. For their belief that his truth was worth more than Cassian’s lie. How could he tell them the ship had reached its destination, that a world waited outside their hull, when they couldn’t even draw a clean breath?

He moved through the med-bay, checking filters, rerouting ventilation, jury-rigging purification units from whatever he could scavenge. He worked until his hands trembled and his eyes burned, until the coughing became a white noise in his skull and the smell of sickness clung to his clothes like a shroud.

At some point, he found an empty storage room and collapsed against the wall, his head in his hands. The data chips in his pocket dug into his thigh—the log fragment, Jena’s original chip, the one he’d never read. The Heartstone was in his other pocket, a small, smooth weight that had belonged to his sister, that had somehow found its way back to him after all these years.

He pulled it out and held it in his palm. It was unremarkable—a dark, crystalline stone, its surface etched with fine lines that caught the light if you tilted it just so. Jena had left it for him alongside the chip. She’d never explained its purpose, and in the chaos of the broadcasts and the battles, he’d never asked.

Now he turned it over, running his thumb across the etched lines, feeling the faint warmth that radiated from its core. Something about it felt alive. Something about it felt like it was waiting.

But he had no time for mysteries. He had a ship to save, people to protect, and a sickness to stop before it tore the rebellion apart from the inside. Cassian had gambled that fear would be a stronger weapon than truth. For now, Kaelen had to prove him wrong.

He pocketed the Heartstone and stood, wiping his face with the back of his hand. Outside, the coughing continued. The war for the ship was far from over, and the enemy wasn’t wearing armor. The enemy was in the air, in the water, in the lungs of everyone who had trusted him.

Kaelen walked back into the med-bay, picked up a wrench, and went back to work.
