The alley smelled like rust and old rain. Mod kept his steps quiet, eyes on the Chronos truck idling at the far end. It sat under a broken light, its dark hull covered in graffiti that the corp hadn't bothered to clean. Nobody cleaned anything in this part of Old Arcadia.
Aphrodite moved beside him, reading the street the way she always did. Corners before doorways. Exits before entrances. She had carried a blade since she was fifteen because it never showed up on a scan.
The truck's rear door was open a crack.
"You sure about this?" she murmured.
"Positive."
They moved fast. Mod eased the door open and they slipped inside.
The interior was cold and clean, the opposite of everything outside. Blinking consoles. Tangled cables. A hum of machinery. And in the center, locked into a cradle of steel arms and wires, a robot dog.
It was built like a wolf. Angular, low to the ground, covered in matte black plating. Faint blue lines ran along its spine and legs, pulsing slowly, like a heartbeat. Its sensor eyes were dark. Pointed at nothing.
Mod crouched beside the cradle. The lock was layered. He pulled out his datapad and jacked in.
The system fought back. Every time he cleared one layer, another came up. The console lights flickered in time with his work. Sweat gathered at the back of his neck.
"Almost there," he muttered.
The console beeped. Sharp. Accusing.
"They've pinged me."
Aphrodite didn't wait. She drew her blade and cut through the cable bundle holding the cradle closed. Sparks hit the ceiling. Alarms screamed and the lights went red.
The cradle snapped open.
The robot dog dropped to the floor, landed on all four feet without a sound, and looked up at Mod. Its sensor eyes flickered blue-white.
Alive.
"Move," Aphrodite said.
They ran. The robot dog ran ahead of them, faster than it looked, weaving through the lower transit corridors. Mod heard a drone before he saw it. The thin whine of rotors cutting through the noise above.
He ducked. The robot dog reacted first. A burst of electrical interference shot from its frame. The drone spun, clipped a wall, and crashed in a shower of sparks.
Mod stopped. Just for a second.
"Did it just—"
"Yes," Aphrodite said. "Keep going."
They made it to a crumbling warehouse two blocks east, its roof half-open to the clouded sky. Mod leaned against the inside wall and let himself breathe.
The robot dog sat beside him. Not because it was trained to. Just because it did.
He pulled out the link device with the cracked screen and opened a port at the back of the robot dog's neck. The moment the cable connected, a jolt went through him. Not pain. More like a circuit completing that he hadn't known was open.
Data came through in pieces. Mission records. Patrol routes. Corrupted memory blocks. And then, clear as anything, a memory that didn't belong to the machine.
Viper's handshake. Two fists, two bumps. The grin after.
Mod had done it a hundred times. He hadn't let himself think about it because thinking about it meant thinking about everything else. The robot dog had it stored somewhere in its core. It had absorbed it from him when the cable connected, or from someone Viper had known before. He didn't know which. He wasn't sure it mattered.
He unplugged the cable.
The robot dog looked at him. Lifted a paw. Tapped his open hand twice. Deliberate. Patient.
Mod didn't say anything. He sat with it for a moment. The warehouse was quiet around them.
"You got it," he said finally. His voice came out smaller than he meant it to. "Just like Viper."
The robot dog's tail moved. One slow wag.
Mod reached into his pack and found the drone decoy orb he'd been carrying for two weeks. He tossed it across the floor. The robot dog's ears snapped forward. It chased the thing, batted it with one paw, watched it roll back. Did it again. The blue lines along its frame pulsed brighter when it moved.
It was still a weapon. It was also, right now, this.
"Cache," Mod said. The name just came. "You store everything you see. That's what you are."
Aphrodite watched from across the warehouse. Her expression had gone somewhere quieter than usual.
"You're keeping it."
"Yes."
She didn't argue. She sat down and let him have the moment.
The resistance base was a warehouse on the lower ring's edge, its walls thick with scrap metal and noise. Rook met them at the door and gave Cache one look with his scanner.
"It's broadcasting on four frequencies right now," he said. "They'll walk right in."
"Can you kill the signal?"
"Give me twenty minutes."
Rook went to work. Cache sat still for it, watching Rook's hands with its sensor eyes, making a low sound in its chest that wasn't quite mechanical. Something closer to patience.
Rook had pulled three trackers and was reaching for a fourth when the alarms went off.
Mod's stomach dropped. "They didn't wait."
The doors blew open. Chronos enforcers came in fast and organized. Not a sweep. A targeted extraction. They weren't here to shut the base down. They were here for Cache.
The fight was fast and loud. Cache moved through the enforcers like it had studied them in advance. Its shock emitters fired in short precise bursts. It took down three before they adjusted.
Then the net launchers came out.
First one shot, then two at once. Cache twisted to avoid the first and was clipped by the second. The third brought it down completely. It hit the floor hard, legs tangled in electrified cord, and the sound it made was not the sound of a machine. It was something worse than that.
A goon stepped forward with an electric prod.
Mod was already moving when the prod hit Cache's chassis. The scream it made landed behind his sternum and stayed there.
He threw himself at the enforcer. Got slammed back. Got up. Threw himself again. Kicked the prod free. Dropped down and pulled Cache against him.
Cache was still looking at him. Eyes still blue. Still there.
Two enforcers pulled them apart. A containment unit sealed around Cache. The blue glow dimmed.
The unit closed.
The enforcers withdrew. Mod stood in the wreckage of the base and did not move for a long moment.
Rook walked over and stood beside him. He didn't say anything.
Later, Mod sat with the data fragments Rook had salvaged before the attack. Most of it was corrupted. But the facility coordinates buried in Cache's mission logs were intact.
He had seen those coordinates before. Three months ago. The night Viper died.
He had run a background scan, the kind he ran out of habit when things went wrong. It had flagged a remote access log from a military compound that was supposed to have been dead for twenty years. He had set it aside. There was too much else happening. He had forgotten it until now.
Cache had been built there. In the same facility that had been watching the night Viper crossed the perimeter.
Aphrodite crouched beside him. Her jaw was set the way it got when she had already decided something and was waiting for everyone else to arrive.
"I know where they're holding him," she said. "Let's go get him back."
Mod stared at the screen.
"Yeah," he said quietly. "Let's."
