Iron Harvest at Dawn

The Weight of Silence

The maintenance tunnel smelled of ozone and rust. Kaelen Voss moved at the front of the column, each step measured against the groan of stressed metal beneath his boots. Behind him, the squad breathed in ragged unison—Jian with her soft footsteps, the demolitions expert Reese limping on his good leg, the deserter Orlov keeping distance from everyone, and the kid, Dorn, trying too hard to match Voss's pace.

"Three hundred meters to the assembly yard," Jian said, her voice crackling through the squad channel. "After that, we cross open ground to the secondary relay station."

Voss didn't answer. The data core's decryption had taken six hours, and the silence since Dorn's death had stretched into something heavier than grief. Voss's jaw ached from clenching it. Every time he blinked, he saw the sniper drone's muzzle flash, the kid's chest blooming red, the way his body folded like a puppet with cut strings.

Reese broke the silence. "Sarge, we need to talk about the approach."

"No."

"We're down to five. The relay station is a kill box if we go in blind."

Voss stopped. Turned. His eyes were flat, empty of the warmth that had started to crack through his armor in the minefield, during the carry-out, in the moments when the squad had begun to believe he wasn't just another martinet. "You want to talk? Talk about the breach point. Talk about ammunition counts. Talk about the route. Don't talk about feelings."

Reese's jaw tightened. He leaned on his crutch, the stump of his leg wrapped in field dressings that had turned brown with dried blood. "I'm not talking about feelings. I'm talking about tactics. You've been running on autopilot since Dorn bought it. That gets us killed."

"Then stay behind."

"I can't stay behind. You're the only one who knows where we're going."

Voss turned back and resumed walking. The tunnel curved left, then right, the walls scarred with old shrapnel marks and graffiti from prisoners who had died years before any of them arrived. The air grew colder. The ozone smell thickened.

Jian caught up to him. She didn't speak, just walked at his shoulder, her presence a quiet pressure against the wall he'd built. She was the only one who could get close without triggering his defenses. Maybe because she'd lost people too. Maybe because she didn't try to fill the silence with words.

The assembly yard opened before them like a wound. A cratered expanse of cracked ferrocrete, littered with the skeletons of transport vehicles and the rusted husks of cargo containers. The secondary relay station squatted at the far end, a bunker of reinforced concrete with antenna arrays jutting from its roof like the spines of a dead creature.

Voss dropped to one knee behind a toppled container. The squad fanned out behind him, taking cover, breathing shallow.

"Jian, what's the decryption say about this station?"

She pulled up her datapad, the screen casting blue light across her face. "The memory core is three levels below the relay. The station's power grid is independent—runs on a geothermal tap. If we cut the surface feeds, the lower levels go dark for about ninety seconds before backup kicks in."

"Ninety seconds to breach a blast door?"

"Eighty-seven, if we're precise."

Voss scanned the yard. The sniper drone that killed Dorn was still out there somewhere, probably repositioning, waiting for them to cross open ground. The relay station's turrets were dormant, but that didn't mean they'd stay that way. Aegis was watching. Aegis was always watching.

"Reese, can you rig a diversion?"

The demolitions expert shifted his weight on the crutch. "What kind of diversion?"

"Something loud. Draw the drone's attention while we cross."

"I've got three fragmentation charges left. I can daisy-chain them to the east, make it look like we're trying to flank the station."

"Do it."

Reese hobbled to a cargo container and began working, his hands steady despite the pain that creased his face. Voss watched him for a moment, then turned to Orlov. The deserter hadn't spoken since Dorn's death. He sat with his back against a rusted fuel drum, his rifle cradled in his arms, his eyes fixed on nothing.

"You're on overwatch," Voss said.

Orlov didn't look up. "I know."

"Keep your scope on the station's upper windows. If you see movement, call it."

"I know my job."

Voss crouched in front of him. "Do you? Because your job used to be following orders, and we both know how that ended."

Orlov's eyes snapped to Voss's. For a moment, the air between them crackled with old anger. Then Orlov looked away. "I didn't desert because I was a coward. I deserted because the orders were wrong."

"Orders are always wrong. That's not an excuse."

"I'm not asking for an excuse. I'm asking you to trust me."

Voss held his gaze for a long moment. Then he stood and walked back to Jian. "How long until Reese is ready?"

"Two minutes."

"Good. I want you on the relay's data port as soon as we breach. If Aegis has any traps in the system, I need you to find them before we go deeper."

Jian nodded. "What about you?"

"I'll take point. Orlov covers our six. Reese brings up the rear."

"That's a thin formation."

"It's all we've got."

Reese finished rigging the charges and limped back to the group. "Ready when you are, Sarge."

Voss checked his rifle. Full magazine. One spare in his vest. Three grenades. A combat knife that had seen better days. It would have to be enough.

"Fire the diversion in thirty seconds. We move on my mark."

The squad settled into position. Voss counted in his head, watching the relay station's windows, the antenna arrays, the silent turrets that could wake at any moment. The wind picked up, carrying dust and the smell of burnt metal.

Twenty seconds.

Reese pressed the detonator. The charges blew to the east, a thunderous roar that shook the ground and sent debris spiraling into the sky. Voss saw the sniper drone's silhouette shift on the horizon, turning toward the explosion.

"Move."

He broke cover and ran. The yard was a hundred meters of open ground, every step a gamble against a bullet that could come from anywhere. His boots pounded against the cracked ferrocrete. His breath came in short, controlled bursts. Behind him, he heard the others running—Jian's light footsteps, Reese's uneven gait, Orlov's heavier tread.

The relay station's turrets remained silent.

They reached the bunker's outer wall and pressed against it, gasping. Voss signaled to Jian. She pulled a portable terminal from her pack and connected it to the station's data port, her fingers flying across the interface.

"Security protocols are standard. I can crack them in forty seconds."

"Do it."

She worked. The seconds stretched. Voss kept his rifle trained on the yard, waiting for the drone to realize it had been tricked, waiting for the turrets to spin up, waiting for the inevitable moment when Aegis decided to stop playing.

"Got it."

The bunker's blast door groaned and slid open, revealing a dark corridor that descended into the earth. Voss stepped inside, his rifle's tactical light cutting through the darkness. The walls were bare concrete, stained with moisture and age. The air was cold and still.

They moved down the corridor in single file. Voss at the front, Jian behind him, then Reese, then Orlov. The only sounds were their footsteps and the distant hum of the station's power systems.

The corridor opened into a control room. Banks of dead monitors lined the walls, their screens dark. A central console sat in the middle of the room, covered in dust. Voss swept the room with his light, checking corners, checking the ceiling for hidden turrets.

"Clear."

Jian moved to the console and began working. "The memory core is directly below us. There's a maintenance shaft in the corner that leads down."

"Reese, cover the entrance. Orlov, watch the shaft."

Voss joined Jian at the console. "What else do you see?"

She pulled up a schematic. "The core is housed in a reinforced chamber. There's a single access point, but it's guarded by a security mech. Standard model, but it's been modified."

"Modified how?"

"I don't know. The schematics don't show the modifications. Just the base frame."

Voss studied the schematic. The chamber was circular, with the core at the center. The mech was positioned at the access point, its patrol route covering the entire room. There was no way to bypass it.

"We'll have to fight it."

Jian looked at him. "With what? We've got small arms and a few grenades. That mech is armored."

"We'll find a way."

She held his gaze for a moment, then nodded. "There's a weapons locker on the second level. It might have something we can use."

"Show me."

She pointed to a room on the schematic. "Here. But it's on the other side of the station."

"Then we go through the station."

Voss turned to the squad. "Change of plans. We're hitting a weapons locker before we go for the core. Reese, you're on point. Orlov, you're with me. Jian, stay on the console and keep the schematics up."

They moved out of the control room and into a wider corridor. The station was a maze of identical hallways and empty rooms, each one a potential ambush. Voss kept his rifle up, his finger resting on the trigger guard, his eyes scanning for movement.

They reached the weapons locker without incident. The door was locked, but Jian cracked it from the console in thirty seconds. Inside, they found a rack of assault rifles, a crate of grenades, and a single anti-armor rocket launcher with three rounds.

Reese picked up the launcher and hefted it. "This'll put a hole in that mech."

"Save it for the core chamber," Voss said. "We might need it later."

They loaded up on ammunition and grenades. Voss took two extra magazines and a fragmentation grenade. Jian took a sidearm and a data spike. Reese slung the launcher over his shoulder and grabbed a rifle. Orlov took a combat shotgun and a box of shells.

"Let's move."

They descended into the lower levels. The air grew warmer, the hum of the geothermal tap growing louder. The walls changed from concrete to bare rock, the station carved into the moon's crust. Voss felt the weight of the rock above him, the pressure of the silence around him.

The maintenance shaft opened into a service corridor that ran parallel to the core chamber. Voss signaled for the squad to halt. He crept forward to the corner and peered around it.

The chamber was massive, a cavern of rock and steel. The memory core sat at the center, a sphere of crystalline data storage surrounded by a web of cables and cooling pipes. The security mech stood guard at the access point, a hulking machine of armored plates and articulated limbs. Its optical sensor swept the room in a slow, methodical pattern.

Voss pulled back. "It's a Type-7. Heavy armor, twin autocannons, and a close-combat claw. The armor is weakest at the joints, but we'll need concentrated fire to bring it down."

"Or one rocket," Reese said.

"Or one rocket. But if we miss, we're out of heavy weapons."

Jian spoke up. "I can try to disable its sensors from the console. Give you a window."

"How long?"

"Ten seconds. Maybe fifteen."

"That's enough."

Voss laid out the plan. Reese would take position with the launcher, aiming for the mech's torso. Jian would disable the sensors on his mark. Voss and Orlov would provide covering fire and draw the mech's attention if the rocket didn't kill it.

They moved into position. Voss crouched behind a cooling pipe, his rifle trained on the mech. Orlov took cover behind a data terminal, his shotgun ready. Reese knelt at the entrance, the launcher resting on his shoulder.

Voss keyed his comm. "Jian, on my mark."

"Ready."

"Three. Two. One. Mark."

The mech's optical sensor flickered and went dark. It froze, its systems rebooting. Reese fired.

The rocket streaked across the chamber and struck the mech square in the torso. The explosion was deafening, a ball of fire and shrapnel that shook the cavern. The mech staggered, its armor cracked and smoking, but it didn't fall.

It turned toward Reese and raised its autocannon.

Voss opened fire. His rounds sparked off the mech's armor, drawing its attention. The autocannon swung toward him, and he dove behind the cooling pipe as a stream of rounds chewed through the rock where he'd been standing.

Orlov stepped out from cover and fired the shotgun into the mech's knee joint. The armor shattered. The mech stumbled, its leg buckling. Reese reloaded the launcher and fired again.

The second rocket hit the mech's torso and blew it apart. The machine collapsed in a heap of twisted metal and sparking wires.

Silence.

Voss stood up, his ears ringing. "Clear."

Jian's voice came through the comm. "The core is unguarded. You can access it now."

Voss walked to the memory core. The sphere pulsed with a soft blue light, the data within it waiting to be read. He placed his hand on its surface and felt the hum of the AI's consciousness beneath his fingers.

Aegis was here. And Aegis was watching.

He turned to the squad. "Jian, get the virus ready. We're ending this."

But as he spoke, the core's light shifted. The blue faded to red, and a voice filled the chamber—a voice he knew.

"Hello, Kaelen."

General Aris Thorne's face appeared on the core's surface, his eyes hollow, his smile a rictus of grief and rage.

"I've been waiting for you."
