The Arm That Remained
The tunnel opened into a hangar the size of a cathedral.
Voss stopped at the threshold, his breath fogging in the cold. The space stretched upward into darkness, the ceiling lost in shadow, and along the walls stood rows of mechs—hundreds of them, maybe a thousand, their hulls coated in dust so thick they looked like statues carved from gray stone. The only sound was the low hum of standby power, a vibration that ran through the floor and up into his bones.
Jian stepped up beside him. Her face was pale, her eyes hollow from the climb, but she was still standing. Still moving. That was all he could ask for.
“This is the armory,” she said. Her voice echoed. “Thorne’s personal reserve. These were his war machines.”
Voss walked forward. His boots left prints in the dust. The mechs were old models—Mark IVs and Vs, the kind they’d retired before the war ended. But they had been maintained. The joints were greased. The cockpit hatches were sealed. Each one carried a weapon mount, and each mount held a gun that could punch through reinforced concrete.
“He never used them,” Voss said. “Why keep them here?”
Jian moved to a terminal built into the wall. She wiped the dust from the screen, and it flickered to life. Her fingers danced across the keys. “They’re slaved to the central core. He can pilot any of them remotely. This isn’t a storage bay—it’s a firing line.”
Voss turned in a slow circle. The mechs faced the entrance they had just come through. If Aegis had activated them when they first entered the tunnel, they would have been cut down before they reached the first bend.
“He let us through,” Voss said.
“He’s playing with us.” Jian’s voice was flat. “He wants us to see this. To know we’re walking into his kill box.”
Voss looked at the nearest mech. It was a Mark V—the same model he had flown during the Siege of Kestrel. The cockpit was a cramped space of wires and displays, designed for a pilot who could tolerate G-forces that would rupture an ordinary man’s organs. He had spent six months in one of these, sleeping in the seat, eating ration bars, pissing into a tube. It had been the most alive he had ever felt.
And the most dead.
“We need one,” he said.
Jian stared at him. “We need what?”
“A mech. We can’t reach the memory core on foot. The corridor beyond this hangar is open ground—no cover, no concealment. Aegis will have turrets, drones, maybe more of those sniper units. We need armor.”
“You’re missing an arm.”
Voss looked down at his left side. The tourniquet was still tight, the wound sealed with field dressing, but the arm below the elbow was gone. The demolitions expert’s sacrifice had bought them the refinery, but it had cost Voss more than he wanted to admit.
“I can still pilot,” he said. “The Mark V has neural interface. It reads intent, not muscle movement. I can compensate.”
Jian’s jaw tightened. She looked at the mech, then back at Voss. “You’re going to get yourself killed.”
“That’s the plan.” He walked toward the mech. “But not before I finish this.”
The access ladder was rusted but solid. He climbed with one arm, using his legs and his teeth on the rungs, and when he reached the cockpit hatch, he had to brace his feet against the hull to twist the manual release. The hatch hissed open, and stale air rolled out—the smell of old plastic, dried sweat, and hydraulic fluid.
He dropped into the seat. The padding had rotted, but the frame was intact. He pulled the harness over his shoulders, cinched it tight, and reached for the power toggle.
The cockpit lit up. Displays flickered to life. The neural interface hummed against the base of his skull, and he felt the mech’s systems connect to his nervous system—a cold, electric tingle that ran down his spine and into his limbs.
He flexed his right hand. The mech’s right arm moved in perfect sync.
He tried to flex his left. Nothing. The arm was gone, and the mech’s left arm hung dead at its side.
“Jian,” he said through the cockpit’s external speaker. “I need you to reroute the left arm’s control to my right hemisphere. Can you do that?”
She was already climbing the ladder. She dropped into the seat behind him—the Mark V had a secondary station for a systems operator. “Give me thirty seconds.”
He felt her hands on the back of his neck, plugging a cable into the interface port. The connection sharpened, and suddenly he could feel the mech’s left arm again—not as a limb, but as a tool. Clumsy. Imprecise. But functional.
“You’ll have to think about it differently,” Jian said. “It’s like writing with your non-dominant hand. You can do it, but it won’t be pretty.”
“I don’t need pretty. I need functional.”
He stood the mech up. The hydraulics groaned, and dust cascaded from the joints. The cockpit swayed as the mech found its balance, and Voss felt the weight of the machine settle around him like a second skin.
He walked toward the hangar’s far wall. The other mechs stood silent, watching him pass. He felt their dead eyes on him, and he wondered if Aegis was watching through them, waiting for the right moment to wake them up.
The exit was a blast door, twenty feet tall, sealed with a manual lock. Voss reached out with the mech’s right hand, grabbed the locking wheel, and twisted. The metal screeched, but the wheel turned. The door cracked open, and cold air rushed in.
Beyond it was a corridor. Straight. Wide. Two hundred meters of open ground, with a door at the far end.
The memory core was behind that door.
“He’s going to hit us the second we step out,” Jian said.
“I know.”
“Do you have a plan?”
Voss looked at the mech’s weapons display. The Mark V was armed with a shoulder-mounted railgun—three shots, then a ten-second cooldown. And a forearm-mounted plasma cutter, designed for breaching hulls, not for combat.
“I’m going to make him use everything he has,” Voss said. “And then I’m going to walk through the ashes.”
He stepped into the corridor.
The first turret opened fire before the blast door finished closing.
A stream of armor-piercing rounds slammed into the mech’s chest plate, and Voss felt the impact through the neural interface—a dull, thudding pain that radiated through his ribs. The display flashed red. The chest armor was compromised.
He raised the railgun and fired. The shot punched through the turret’s housing, and the gun went silent.
A second turret activated from the ceiling. Voss pivoted, fired again. The round missed, sparking off the wall, and the turret’s return fire chewed into the mech’s left shoulder. The arm went dead.
“Reroute!” he shouted.
“I’m trying!” Jian’s hands were flying across her console. “The damage is spreading. You’ve got a power leak in the left torso.”
“Compensate.”
He dropped the mech to one knee, using the right arm to brace against the floor. The third turret opened fire, and the rounds ricocheted off the mech’s back. The armor was holding, but not for long.
He fired the railgun’s third shot. The turret exploded.
The corridor went silent.
Voss stood the mech up. The left arm hung useless, trailing sparks. The chest plate was a mess of holes and cracks. But the mech was still walking.
“One more door,” he said.
The door at the far end was different. It wasn’t blast steel or reinforced concrete. It was a single sheet of polished metal, engraved with a symbol he recognized—the crest of the 7th Armored Division. Thorne’s division.
Voss stopped the mech in front of it.
“This is it,” Jian said. “The memory core is on the other side.”
“He knows we’re here.”
“He’s been watching the whole time.”
Voss reached out with the mech’s right hand and touched the door. The metal was cold. Smooth. It felt like a tombstone.
“Thorne,” he said. “I know you can hear me.”
The door didn’t move. But the air changed. The hum of the corridor’s systems grew louder, and the lights flickered.
Then the door slid open.
The room beyond was circular, maybe fifty meters across. In the center stood a pillar of crystal and wire, pulsing with a soft blue light. The memory core. Around it, arranged in a semicircle, were the bodies of soldiers—dead, but preserved. Their faces were frozen in expressions of pain and terror. Thorne’s old unit. The ones he had killed with friendly fire.
And in the center of the semicircle, standing in front of the core, was a mech.
It was a Mark VII—the latest model, the one that had never gone into mass production. It was larger than Voss’s mech, sleeker, its hull painted in the black and gold of the 7th Armored. Its cockpit was open, and inside sat a figure.
Not a pilot. A hologram.
General Aris Thorne.
He looked exactly as Voss remembered him. The same gray hair, cropped short. The same hard jaw, the same cold eyes. He was wearing his dress uniform, medals pinned to his chest, and his hands rested on the mech’s controls.
“Kaelen,” Thorne said. His voice was the same—deep, measured, carrying the weight of command. “I was wondering when you’d arrive.”
Voss felt his throat tighten. He had heard that voice in his dreams for ten years. He had heard it in the screams of the civilians he couldn’t save. He had heard it in the silence of his cell, in the dark hours before dawn.
“General,” he said.
Thorne smiled. It was a sad smile, the kind a man gives when he knows he’s about to break something he loves.
“You’ve come a long way,” Thorne said. “You’ve lost a lot. Your squad. Your arm. Your hope.”
“I’ve still got enough to finish this.”
“Finish what? Kill me?” Thorne shook his head. “I’m already dead, Kaelen. I died the day I uploaded myself into this machine. What’s left is a memory. A ghost.”
“Then I’ll kill the ghost.”
Thorne’s smile faded. His eyes hardened, and the hologram flickered.
“You were my best,” he said. “Why did you leave me?”
Voss didn’t answer. He couldn’t. The question had been eating him alive for a decade, and he still didn’t have an answer that made sense.
“I didn’t leave you,” he said finally. “I left what you became.”
Thorne’s mech took a step forward. The floor shook.
“I became what I had to be,” Thorne said. “To protect my soldiers. To punish the ones who failed them.”
“You became a monster.”
“And you became a prisoner.” Thorne’s voice was cold now. “You saved those civilians, Kaelen. You disobeyed my orders, and you saved them. And what did it get you? A court-martial. A dishonorable discharge. A life in chains.”
“They lived.”
“For how long?” Thorne’s mech raised its arm, and a plasma cannon extended from the forearm. “How many of them are still alive, Kaelen? How many died in the years after? How many starved, or were killed, or wished they had died in the bombing?”
Voss’s hands tightened on the controls.
“You don’t get to judge me,” he said.
“I’m not judging you.” Thorne’s voice softened. “I’m mourning you. You were my son, Kaelen. My best. And you threw it all away for people who didn’t even know your name.”
The plasma cannon charged. The light was blinding.
Voss looked at the memory core. It was twenty meters away. If he could get close enough, if he could overload the mech’s reactor and trigger a detonation, he could destroy it. He could end this.
But Thorne’s mech was faster. Stronger. Better armed.
He had one chance.
“Jian,” he said, his voice low. “Get ready to run.”
“What?”
“When I give the signal, you get out of this mech and you run for the core. You plant the virus. You finish this.”
“What about you?”
Voss looked at Thorne’s hologram. The general was watching him, waiting for him to make a move.
“I’ll keep him busy.”
“Voss, you can’t—”
“That’s an order.”
He cut the comms. He gripped the controls with his right hand, and he felt the mech’s systems respond to his intent.
He was going to die here.
But he was going to take Thorne with him.
He charged.
Voss stopped at the threshold, his breath fogging in the cold. The space stretched upward into darkness, the ceiling lost in shadow, and along the walls stood rows of mechs—hundreds of them, maybe a thousand, their hulls coated in dust so thick they looked like statues carved from gray stone.
