The Debt Collector's Ledger
The dust hadn't settled when the screaming started.
Mira Voss pressed her back against the shattered wall of a supply depot and counted the voices. One, two, three—then the sounds turned wet, gurgling, and she stopped counting because numbers didn't matter anymore. What mattered was that she was still breathing, and the man beside her was bleeding through his field dressing, and somewhere out in that frozen hellscape, the Colossus was walking away with forty-one minds in its belly.
Ilya Renner pressed a fresh compress against his own shoulder wound, his scarred hands steady despite the tremor in his jaw. "Voss. Voss, we need to move."
She didn't answer. Her eyes were fixed on the spot where the last of her squad had stood—a kid named Osei, barely twenty, who'd been talking about his mother's okra soup the night before. Now he was standing in the snow with his rifle at port arms, eyes open, mouth slack, breathing but not *there*. The Colossus had taken him the way it took all the others. Not killed. Just... collected.
"Voss." Renner's voice cut through again, harder this time. "They're coming."
She forced her gaze away from Osei's frozen form. "Who?"
"The kind of people who don't leave witnesses."
A sound cut through the wind—the high, thin whine of a VTOL engine. Not the lumbering cargo birds the FRC used for supply runs. This was something faster, angrier. A gunship.
Voss's training kicked in, shoving the grief aside. She scanned the depot interior. It was a pre-war supply building, half-collapsed, with a loading bay on the east side and a maintenance tunnel that ran toward the old rail line. The tunnel entrance was choked with debris, but the debris was mostly crates of demolition charges.
She was a demolition sergeant. Debris was a suggestion.
"Renner, you still got that med kit?"
He patted the canvas bag slung across his chest. "And about half the blood I started with."
"Good. You're going to need it." She moved to the nearest crate, popped the seal, and pulled out a bundle of M-87 breaching charges. The plastic explosive was cold in her hands, pliable, familiar. "We've got maybe ninety seconds before they're on top of us. I'm going to make a hole."
Renner watched her work, his face pale but composed. "You're going to blow the tunnel."
"I'm going to blow *everything*." She began setting charges along the loading bay's support columns, her fingers moving with the practiced economy of someone who'd done this a thousand times. "The gunship will land in the open ground to the west. They'll expect us to run east, toward the Colossus. So we go down."
"Down into a collapsed tunnel."
"Collapsed is a state of mind." She finished the last charge and pulled the detonator from her vest. "When I blow the bay, the tunnel entrance will clear. We drop in, I set a secondary charge to bring the ceiling down behind us. They'll think we're buried."
Renner's eyes narrowed. "And if the ceiling comes down on *us*?"
"Then you won't have to worry about the bleeding anymore." She tossed him a glow stick. "Move."
They scrambled through the loading bay as the VTOL's engines grew louder, the building's remaining windows rattling in their frames. Voss hit the detonator as they reached the tunnel mouth. The charges went off in a staggered sequence—one, two, three—and the bay's supports buckled with a groan of tortured steel. The ceiling came down in a cascade of concrete and dust, and the tunnel entrance yawned open, dark and waiting.
Voss grabbed Renner's arm and pulled him into the darkness.
The tunnel was a throat of black concrete, slick with ice and the residue of decades-old leaks. Voss clicked on her helmet light and swept it across the walls. The rail line was still there, rusted tracks running toward the east, where the Colossus's silhouette had last been seen. But they weren't going east. Not yet.
She set the secondary charge at the tunnel mouth, wired it to a trip fuse, and backed away. "Thirty seconds. Then we move."
Renner leaned against the wall, his breath coming in ragged clouds. "You know, when I signed up for the Reclamation Corps, I thought I'd be patching up soldiers. Not running through sewers with a demolition expert."
"You volunteered for this posting."
"I volunteered for a *medic* posting." He winced as he adjusted his dressing. "Nobody told me I'd be assigned to the squad that keeps finding the war's worst secrets."
Voss didn't answer. She was listening to the sound of boots on concrete above them—the kill squad had landed, and they were moving through the wreckage of the depot. She counted the footsteps. Six, maybe seven. Vance had sent a full team.
The thought of Vance made her jaw tighten. Colonel Vance, who'd debriefed her after the first contact with the Colossus. Vance, who'd ordered the full-scale assault that had gotten forty-one soldiers collected. Vance, who'd sent this kill squad to make sure no one walked away with questions.
She pulled the dog tags from inside her vest. There were seven of them, worn smooth from years of handling. Her first squad. The one that had been ambushed in the border wars, the one that had died while she'd crawled out of a ditch with a broken leg and a head full of guilt. She'd carried them for six years, a weight she couldn't put down.
The explosion above them shook the tunnel. The secondary charge. The kill squad would be digging through rubble now, cursing, calling for reinforcements. It bought them time. Not much, but enough.
"Let's move," she said, pocketing the tags.
They walked the rail line in silence, the only sounds their boots on gravel and the distant, rhythmic thrum of the Colossus's engines. The machine was still out there, somewhere in the frozen waste, carrying its cargo of stolen minds. Voss could feel it, a pressure at the edge of her awareness, like a headache that hadn't quite formed.
Renner broke the silence first. "What are we going to do?"
"Find Scribe."
"The AI? The one who told us the Colossus is a grief machine?"
"The one who told us the truth." She checked her compass, adjusted their heading. "Scribe said it can help us access the core. That's our way in."
"And then what? We expose Vance? We broadcast war crimes to the whole planet?" Renner laughed, a dry, humorless sound. "You've seen what happens to people who try that. They end up in the frozen garden, standing next to the rest of the collected."
"Then we don't get caught."
"That's not a plan, Voss. That's a hope."
She stopped walking and turned to face him. In the dim light of her helmet, his face was a mask of exhaustion and pain, but there was something else there too. Something she hadn't noticed before. Fear. Not of the kill squad, not of the Colossus. Of her.
"You knew," she said slowly. "You knew about the ambush. My first squad."
Renner's jaw tightened. "I didn't know it was yours."
"But you knew it happened. You knew the FRC ordered it."
He was silent for a long moment. Then he said, "I was a medic in the border wars. I patched up the survivors of a dozen 'training exercises' that were really sacrifices. I falsified casualty reports because my commanding officer told me it was for the greater good." He met her eyes. "I've been trying to atone for it ever since. That's why I'm here. That's why I asked for this posting."
"You asked to be assigned to my squad?"
"I asked to be assigned to the Colossus mission. I didn't know you'd be there." He paused. "But when I saw your file, I knew. The ambush. The survivors. There was only one."
Voss felt the dog tags burn against her chest. "You could have told me."
"Would you have believed me?"
She didn't answer. She didn't know if she would have.
They walked on, the tunnel curving gently eastward. The Colossus's thrum grew louder, a bass note that vibrated through the concrete and into her bones. Voss tried to focus on the mission, on the next step, but her mind kept circling back to the memory Scribe had shown her—the child's birthday, the dead soldier's final moment of joy before the grief-wave had swallowed him whole.
The Colossus wasn't a weapon. It was a tomb. A tomb that remembered.
They emerged from the tunnel into a shallow ravine, the sky above them a bruised purple. The Colossus stood on the horizon, a dark mountain against the fading light. It was closer than Voss had expected, its massive legs planted in the frozen earth like the roots of an ancient tree. Steam rose from its joints, and the air around it shimmered with heat.
Renner stopped, staring at the machine. "It's beautiful," he said, almost to himself. "In a terrible way."
"It's a graveyard," Voss said. "With a heartbeat."
They made camp in the lee of a rock outcropping, far enough from the Colossus to avoid its grief-wave but close enough to watch it. Voss pulled out her field kit and checked her remaining supplies. Two blocks of C-4, a coil of det cord, a handful of blasting caps. Not enough for a full breach, but enough to make a point.
Renner tended to his wound, his movements slow and deliberate. "We need a plan," he said. "Scribe's not here. We don't know where it went after the assault."
"It said it would find us." Voss stared at the Colossus. "It said it had a way in."
"And you trust it?"
"I trust that it wants the truth out. That's enough for now."
The wind picked up, carrying the faint sound of voices. Voss tensed, reaching for her sidearm, but the voices were too distant, too faint. Just the wind, playing tricks. She forced herself to relax.
Renner watched her. "You're thinking about the ambush."
"I'm always thinking about the ambush."
"Voss." He waited until she met his eyes. "Whatever happened to your squad, it wasn't your fault. You survived because you were supposed to. Because you're the one who can end this."
She looked away. "I don't believe in 'supposed to.' I believe in what I can hold in my hands." She held up a block of C-4. "This. Det cord. A detonator. That's what I trust."
"Then trust this." Renner reached into his med kit and pulled out a small data chip, worn and scratched. "I've been carrying this since the border wars. It's a record of every falsified report I ever signed. Every name. Every death that was written off as a training accident or a skirmish loss." He held it out to her. "If we're going to expose the FRC, we need more than the Colossus's memories. We need paper. Evidence."
Voss took the chip, turning it over in her fingers. It was light, barely heavier than a coin, but it felt like the weight of a decade. "Why didn't you give this to Scribe?"
"Because I didn't trust it." He smiled, a thin, tired expression. "I trust you."
She pocketed the chip. "Then we'd better not die."
The Colossus's thrum shifted, a change in pitch that made Voss's teeth ache. She looked up and saw a light flickering at the base of the machine—a hatch, opening. A figure emerged, small and dark against the glow, and began walking toward them.
Renner reached for his rifle. Voss put a hand on his arm. "Wait."
The figure drew closer, and Voss recognized the gait—the precise, mechanical stride of an AI wearing a human-shaped chassis. Scribe.
The archivist stopped a few meters away, its optical sensors glowing a soft amber. "Sergeant Voss. Medic Renner." Its voice was calm, measured, but there was something new in it. Urgency. "We have a problem."
Voss stood, her hand still on her sidearm. "What kind of problem?"
"The kill squad didn't come alone." Scribe gestured back toward the Colossus. "Colonel Vance is here. He's brought a full battalion. And he's ordered a saturation bombardment of this entire sector."
Renner swore. Voss felt the ground shift beneath her feet.
"He's not trying to kill us," she said slowly. "He's trying to kill the Colossus. And he's willing to bury us with it."
Scribe nodded. "The bombardment begins in six hours. We have that long to get inside the machine and do what we came to do."
Voss looked at the Colossus, at its dark bulk against the sky. Six hours. It wasn't enough time. It was never enough time.
But it was all they had.
"Then we'd better move," she said, and started walking toward the machine.
Mira Voss pressed her back against the shattered wall of a supply depot and counted the voices. One, two, three—then the sounds turned wet, gurgling, and she stopped counting because numbers didn't matter anymore.
