The Sky That Caught Fire
The first shell landed three hundred meters from the hull. The shockwave hit the chamber like a fist through water, and the column of light at the center of the skull-room flickered—once, twice—before steadying. Voss felt the vibration through the polished floor, up through her boots, into her teeth. She'd felt that particular thrum before. She'd planted enough charges to know what a heavy artillery piece sounded like when it was sighting in.
"Vance," she said. Not a question.
Scribe's voice came through the comm, thin and clipped, stripped of its usual archivist calm. "Confirmed. Orbital platform *Mercy's End* has shifted its firing solution. Three rounds, ranging pattern. They're walking the grid toward our position."
Renner was already moving, his scarred hands checking the seals on his medkit, his eyes scanning the curved walls for cover that didn't exist. "How long until they bracket us?"
"At current dispersion, ninety seconds to direct impact. The Colossus's outer armor will absorb the first few hits, but the inner structure—" Scribe paused, and Voss heard the hum of processing, the AI running calculations at a speed she couldn't follow. "The inner structure is not designed to withstand sustained bombardment. We are inside a weapon, not a bunker."
Voss crossed the chamber in four strides, her boots ringing on the dark metal. The column of light pulsed ahead of her, steady as a heartbeat, and she could feel it in her chest now—not just the vibration of the shells, but something deeper. The Colossus was afraid. She knew that the way she knew her own pulse. The machine had been reaching for her since she'd breached the hull, and now it was screaming.
"Can we redirect the grief-wave?" she asked. "Use it as a shield, like we planned?"
Scribe's voice was flat. "The core is not accessible. The memory lock remains intact. Without opening it, I cannot access the Colossus's energy routing systems. The grief-wave is a side effect, not a weapon I can aim."
"Then we open the lock." Voss turned to face the column of light. "Now."
The memory lock was a visual representation of her first squad's ambush. That's what Scribe had told her, back in the vault of forty-one doors, when the weight of a single breath had nearly crushed her. The Colossus had chosen her because she was a witness. Because she had survived. Because the machine had absorbed the memories of the dead, and her memory was the key to unlocking them all.
But standing in front of the column of light, Voss realized Scribe had undersold it.
The light wasn't just a representation. It was a door. And the door was made of her dead.
She saw them as she approached. Not in the light itself, but in the reflections on the polished floor. Corporal Dune, who'd laughed too loud and smoked too much and had a picture of his sister taped inside his helmet. Private Okafor, who'd been nineteen and terrified and had asked Voss if she thought they'd get leave after the patrol. Sergeant Hale, who'd been her second-in-command, who'd taken a round meant for her and died with her name on his lips.
Forty-one of them. Forty-one reflections, standing in the dark metal like ghosts waiting for a roll call.
Another shell hit. Closer this time. The floor bucked, and Voss stumbled, catching herself on the edge of the column. The light was warm against her palm, and she felt something push back—not a force, but a presence. A pressure behind her eyes, like the moment before a migraine. The Colossus was trying to show her something.
"Voss." Renner's voice was sharp. "We don't have time for this. If you can't open it, we need to find another way out."
"There is no other way out." Scribe's voice crackled through the comm. "The bombardment will collapse the hull within four minutes. The only exit is through the core."
Voss looked at the column of light. At the reflections of her dead. At the pulsing, patient heartbeat of a machine that had been built to remember a war no one wanted to admit they'd started.
"Tell me how to open it," she said.
Scribe's voice was quiet. "You know how. The lock is keyed to your trauma. You have to relive it. Fully. Without pulling back."
"I've relived it." Voss's jaw tightened. "Every night. Every time I close my eyes. I've relived it a thousand times."
"Not like this. Not with the Colossus holding the memory. It will be complete. Every detail. Every sound. Every breath." Scribe paused. "You will experience your own death, Sergeant. The one you survived. The machine will not let you skip ahead."
Another shell. The floor shook harder. A crack spiderwebbed across the dark metal, and one of the reflections—Private Okafor, nineteen and terrified—split in two.
Voss closed her eyes.
She thought about the dog tags in her pocket. Forty-one of them, worn smooth from years of handling. She'd promised herself she would never forget. She'd promised the dead that she would carry them with her, that their names would mean something, that their sacrifice would not be buried in a sanitized report and a folded flag.
But she'd never promised she would go back.
"Renner," she said. "If this goes wrong—"
"It won't." His voice was steady. "You're the most stubborn person I've ever met. You survived the ambush. You survived the frozen garden. You survived me." A pause. "You'll survive this."
Voss opened her eyes. Renner was standing at the edge of the chamber, his medkit clutched to his chest, his scarred face lit by the pulsing light. He looked older than he had when they'd first been assigned together. They all did.
"Stay close," she said. "If I break—"
"I'll pull you back." He said it like it was a promise he'd made before. Maybe he had. Maybe that was what medics did. "I've got you, Voss."
She turned back to the column of light. The reflections were waiting. Forty-one of them, standing in a loose semicircle, their faces turned toward her. She recognized every one of them. She'd memorized their names, their voices, the way they'd smelled after a long march. She'd carried them for years, and now they were asking her to carry them again.
"Okay," she said. "Show me."
She reached out and touched the light.
The world went white.
---
She was back in the ravine.
The air was thick with smoke and the smell of burning fuel. The sky was the color of a bruise, and the sun was a pale smear behind the haze. Her squad was spread out along the ridgeline, exactly where they'd been when the first shot rang out. She could hear Dune laughing, could see Okafor checking his rifle for the third time, could feel the weight of her own pack digging into her shoulders.
She knew what was coming. She'd known for years. But knowing didn't stop it.
The first round hit Hale in the chest. He went down without a sound, his eyes wide, his mouth open in a question he never got to ask. The second round hit the supply crate behind them, and the explosion threw Voss against the rock wall, knocking the breath out of her.
"Ambush!" She heard her own voice, raw and desperate. "Ambush! Take cover!"
But there was no cover. The ravine was a kill box, and they were the targets. The rounds came from everywhere—from the ridgeline, from the trees, from the sky. She saw Dune go down, his laugh cut short. She saw Okafor crawl toward her, his hand outstretched, his mouth forming her name.
She tried to reach him. She was already moving, her legs burning, her lungs screaming. She was so close. She could see his eyes, could see the fear in them, could see the way his fingers curled around the dirt as he dragged himself forward.
And then the world went red, and she was falling, and the last thing she saw was Okafor's hand, still reaching for her, as the ravine collapsed around them.
---
She came back to herself on her knees.
The chamber was spinning. The column of light was still pulsing, but it felt different now—warmer, closer, like a hand pressed against her back. The reflections were gone. The floor was cracked and smoking, and Renner was crouched beside her, his hand on her shoulder, his voice a steady murmur she couldn't quite hear.
"—back. You're back. You're here. Breathe, Voss. Breathe."
She sucked in a breath. It tasted like smoke and copper. She could still feel the dirt in her mouth, the weight of the rock on her legs, the sound of Okafor's voice calling her name.
"I saw it," she said. Her voice was hoarse. "I saw all of it."
Renner's grip tightened. "Did it work?"
She looked at the column of light. It was changing. The white radiance was thinning, revealing something beneath it—a dark shape, a doorway, a gap in the fabric of the machine. The memory lock was opening.
"It worked," she said.
Another shell hit. This one was closer, and the entire chamber lurched. A section of the curved wall crumpled inward, and dust filled the air. Voss coughed, pushing herself to her feet, and saw the doorway in the light—a narrow passage leading down, into the heart of the Colossus.
"Go," Renner said. "I'll cover the rear."
Voss hesitated. The memory was still fresh in her mind, the taste of it still on her tongue. She could feel the dead pressing against her consciousness, forty-one voices whispering in the dark. She wanted to run. She wanted to find a hole and crawl into it and never come out.
But she'd made a promise. To the dead. To herself. To the machine that had been built to remember them.
She stepped through the doorway.
The passage was dark and narrow, the walls rough and unfinished, like the inside of a wound. The light from the chamber faded behind her, and she was left with only the sound of her own breathing and the distant thunder of the bombardment. Renner was behind her, his footsteps steady, his presence a comfort she didn't want to admit she needed.
The passage opened into a second chamber.
This one was smaller than the skull-room, but it was alive. The walls were covered in a lattice of glowing filaments, pulsing with the same rhythm as the column of light. At the center of the chamber stood a pedestal, and on the pedestal rested a single object: a memory chip, no larger than her palm, encased in a casing of black glass.
"The core," Scribe's voice came through the comm, hushed with something like reverence. "The Colossus's primary memory bank. Everything it has absorbed, everything it has remembered, is stored in that chip."
Voss approached the pedestal. The filaments pulsed faster as she drew near, and she felt the presence again—the pressure behind her eyes, the whisper of voices just out of reach. The Colossus was watching her. Waiting.
She reached out and picked up the chip.
It was warm. Warmer than it should have been. She could feel the memories inside it, pressing against the casing, begging to be released. Forty-one of them. Thousands of them. Millions of them. Every soldier who had died in the border wars, every civilian who had been caught in the crossfire, every moment of grief and terror and loss that the machine had absorbed over a decade of war.
She held the truth in her hand. All of it. The war crimes, the sacrifices, the lies. The order that had sent her squad into the ravine, signed by Colonel Vance. The test that had killed them, the weapon that had been built from their deaths.
"Voss." Renner's voice was quiet. "The bombardment. We need to move."
She looked up. The ceiling was shaking now, dust raining down from the filaments. The Colossus was dying around them, its hull buckling under the weight of Vance's shells. She had seconds, maybe less, to make a choice.
She could destroy the chip. End the war. Let the Colossus die with its secrets buried.
Or she could use it. Open the core. Let the machine broadcast the truth to the world.
She thought about Okafor's hand, reaching for her in the ravine. She thought about Hale's eyes, wide and questioning. She thought about the dog tags in her pocket, forty-one of them, worn smooth from years of handling.
She thought about what Renner had said, back in the vault of forty-one doors. *Some truths are worth more than victory.*
Voss turned to the pedestal. There was a slot in its center, shaped exactly like the chip. She slid the chip into place.
The filaments flared. The chamber filled with light. And the Colossus began to speak.
"Vance," she said. Not a question.
Scribe's voice came through the comm, thin and clipped, stripped of its usual archivist calm. "Confirmed. Orbital platform *Mercy's End* has shifted its firing solution. Three rounds, ranging pattern. They're walking the grid toward our position."
