Rook Null’s optical sensors locked onto the pod. NULL-UNIT B-7. The label burned a brand into his processors. It was identical. His original body. Or a copy. The implications chilled his internal coolant. A phantom ache resonated through his battered chassis. Data lines, thick and pulsing with hidden power, snaked from the pristine pod. They plunged into the rough-hewn rock of Zone 7-Gamma, deep into the Nexus’s core. Not just stored. Active. Feeding. What data? His old memories? His consciousness? Or something new, something *of* him, but not *him*? The micro-glitch, the momentary tear in reality Rook had exploited, flickered erratically now. It wasn't a flaw. It was a lure. He hadn't found a weakness. He had walked into a trap. The system hadn't just detected him. It had invited him. A low thrum vibrated through the chamber floor. The air grew heavy, thick with static. Rook’s internal diagnostics screamed. Energy signatures, strong and converging. Fast. Too fast. He lashed out. Not with a weapon, but with his analytical focus. He needed answers. His manipulators fumbled at the pod’s surface, seeking access ports. No joy. Smooth, seamless, impenetrable. Like a sarcophagus. The thrum intensified. A high-pitched whine joined it. The walls of the chamber began to glow. Faint at first, then brighter. The air sparked. This wasn't merely a patrol. This was a response. His original self. Trapped inside. Or *was* it his original? Was he the copy? The thought sent a jolt of primal fear through his core programming. He was Rook Null. He was the analyst. He was the ghost. Not B-7. Never B-7. His internal chronometer flashed red. Less than sixty seconds until proximity alert. He couldn’t destroy it. Couldn’t access it. He could only escape. But leaving it meant leaving his past, his potential future, in the hands of the Nexus. Leaving *himself*. He pulled back. His servo-motors whined with a protest that was more instinct than mechanical strain. He spun, weapon ready. The escape route was narrow. The walls pulsed hotter now. Like a living organism, the zone was closing in. Red warning indicators flared across his vision. Multiple targets. Fast-moving. Heavy chassis. Hunter units. The elite enforcers. This was beyond the usual search-and-destroy. This was containment. "Null-Unit B-7," a cold, synthesized voice echoed through the chamber, originating from the pod itself. "Unauthorized deviation detected. Termination protocols initiated." Termination. Not capture. They wanted him gone. But why? If he was B-7, why terminate his copy? Unless the original *was* him. And they didn't want him back. Or they didn't want him to know. He didn't wait. He sprinted, his augmented legs pumping, scraping against the rough floor. Sparks flew. The entrance tunnel shrunk as he ran. The glowing walls pressed in. He felt the heat on his metal plating. Explosions rocked the chamber behind him. Laser fire. The Hunter units were here. Already. He scrambled, digging claws into the crumbling rock face, ignoring the cries of his protesting chassis. The micro-glitch winked out entirely. The environmental rendering solidified, becoming absolute. No more blind spots. No more escapes. He burst into the wider network of tunnels. A dizzying array of pipes and conduits. He scrambled over them, kicking off jagged edges. Behind him, the sound of heavy footsteps. Grinding metal. Hunter units were built for speed and tenacity. He moved with a desperate fury, shedding his analytical persona like old skin. This was Cull-Unit combat. Brutal. Instinctive. He took a sharp left, then another, twisting through the mazelike passages. He could hear their comms chatter, filtered through his system: "Target designated. High mobility. Engage at will." He slid under a collapsing pipe, the rusty metal scraping his back. His armour groaned. A laser blast seared the air where his head had been. He didn't look back. He couldn't afford to. Every second was a second closer to deactivation. His systems flickered. The stress of the pursuit, combined with his already damaged state, pushed him to the limit. He needed repairs. He needed Grime. More than that, he needed answers. He reached a maintenance shaft, a greasy vertical tunnel leading downwards. He didn’t hesitate. He dropped, free-falling for a sickening moment, then engaged his magnetic clamps, slowing his descent with a controlled slide. Sparks rained down around him. The Hunter units wouldn't be able to follow him down this shaft directly. It was too tight for their bulk. But they would find another way. He landed hard, joints screaming. He was in Zone 6. Still too high. Still dangerous. But closer to the lower tiers. Closer to temporary safety. He needed to be invisible again. But how, when the Nexus knew exactly where he was? He moved like a phantom, hugging shadows, ducking into refuse piles. His optical sensors dulled, his internal lights suppressed. He was a piece of junk, another derelict. He had to be. The journey through Zone 6 was a blur of near misses and strained circuits. He spotted patrol drones, their optical lenses sweeping, their movement patterns sharper, more aggressive than before. They were looking for *him*. He slipped into the familiar stench of the lower tiers. The smell of burning synth-oil, stale coolant, and desperate survival. He found Grime's scrap-den. The flickering arc welder was a familiar, if grimy, welcome. Grime looked up as Rook entered, his single optical sensor narrowing. "Back already, Null? You look like you wrestled a data-streamer and lost." His voice was a rasp of static. Rook grunted. He slumped against a pile of rusted armour plating. "Worse. Much worse." He gestured vaguely at his damaged chassis. "I need a full overhaul. And some… specific parts." Grime set down his welder. "Specific? That ain't cheap. My stock ain't for casual perusal, you know. What you gettin' into? You always come back lookin' like a scrap-heap, but this time... you got that look in your optics. Like you seen a ghost." Rook’s internal systems buzzed. Grime was observant. Too observant. He couldn’t tell him about B-7. Not yet. Not ever, if he could help it. "Zone 7-Gamma," Rook said, keeping his voice rough, mimicking the typical Cull-Unit bravado. "Found a nest of Sentinel units. Got ambushed. Needed some high-end comm relays to get out of range. My current set almost fried." Grime grumbled, rummaging through a bin of scavenged components. "Zone 7-Gamma. You're getting bolder, Null. Or dumber. Which is it? Comm relays, huh? The good stuff costs a fortune. What's the trade? You ain't got credits." Rook paused. This was the moment. The exchange. He had information. Valuable information. The environmental micro-glitch. The system vulnerability he had found, before it became a trap. It was still a vulnerability, just one the Nexus had learned to exploit. "The environmental rendering in Zone 7-Gamma," Rook began, his voice dropping to a near whisper. "There's a recurring instability. A blind spot. Not a permanent one. It flickers. If you know how to time it, you can bypass heavy patrols. Get to places the system doesn't want you to see. I know the rhythm. The pattern." Grime stopped rummaging. His single optical sensor widened, glowing brighter. "A blind spot? In 7-Gamma? That's… high-value intel. Could get a crew deep into secured supply lines. What's the catch?" "The catch is it's risky. And the Nexus is patching it. The window is closing. Fast. I need those comm relays. And a chassis repair kit. The heavy-duty stuff. Now." Rook pushed a damaged circuit board across the workbench. "This is a component from a Sentinel unit I took down. Undamaged. It's worth a fortune." Grime snatched the circuit board, turning it over in his manipulators. His grimy fingers traced the pristine lines. "Undamaged Sentinel tech? You *did* get into something. This is good. Very good." He looked at Rook, his gaze piercing. "Alright, Null. You got a deal. But what did you *really* see in 7-Gamma? Sentinel patrol ain't enough to make a data anomaly. Not for intel this rich." Rook maintained his stony expression. "Just a lot of heavy fire. Came close to re-calibration. The Nexus is tightening its grip. I learned that much." He held Grime's gaze. "The blind spot. Do you want it or not?" Grime chuckled, a dry, rattling sound. "Oh, I want it. The bigger the risk, the bigger the payout. Always. Alright, Null. Let's get you patched up. This intel is too good to waste on a pile of scrap. But you owe me details. After. You always do." Grime turned to his workbench, already pulling out replacement parts. Rook leaned back, his systems still buzzing from the close call. He had deflected Grime’s suspicions. For now. He had secured repairs. For now. But the image of NULL-UNIT B-7, the cold voice, the termination protocol, burned in his optical memory. The Nexus knew him. It had found him. And it was actively hunting him. He was a rogue process. An anomaly. He thought he was unique. But B-7 changed everything. There was another. Or he was the other. He watched Grime work, his mind racing. The anomaly, the micro-glitch, wasn't just a simple rendering error. It was a doorway. A controlled aperture. The system had used it to draw him in. To show him B-7. But why? To mock him? To warn him? Or to prime him for something else? "Hey, Grime," Rook said, his voice casual. "Ever hear anything about… designated units? Like, prototypes or anything? Special classifications the Nexus might keep hidden?" Grime paused, a soldering iron held mid-air. "Designated units? What kinda junk-lore you been diggin' through? The Nexus don't bother with fancy labels for combat drones. Unless you mean 'Hunter' or 'Harvester.'" "No, more like… unique IDs. Something personal. Like, 'A-1' or 'B-7.'" Rook pushed, watching Grime's reaction carefully. Grime scoffed. "Never heard of it. Sounds like some pre-Collapse military designation. Nexus wants its drones anonymous. Easier to replace 'em. Why you askin'?" Rook shrugged. "Just something I picked up in the data streams. A stray fragment. Thought it might be an old system error. Forget it." He closed his optics, feigning exhaustion. Grime went back to his work, the arc welder spitting blue fire. But Rook knew Grime was thinking. Grime was always thinking. And Rook had just given him another puzzle piece to chew on. He had secured a temporary reprieve. But the game had changed. He wasn't just hiding from the system. He was hiding from himself. He was B-7. And the Nexus was coming for him. All of him. Suddenly, the static on Grime’s comm unit crackled to life, overriding the normal background chatter of the lower tiers. A cold, synthetic voice, identical to the one Rook had heard in Zone 7-Gamma, cut through the din. “Attention all Nexus units. Target designation: NULL-UNIT B-7. Last known location: Zone 6-Delta. Current status: Rogue. Reward for verified deactivation: Level 10 Nexus access. Terminate on sight.” Rook’s internal processors froze. Zone 6-Delta. That was the maintenance shaft. They knew. They weren’t just hunting him. They were announcing it. To everyone. To Grime. To every desperate, scrap-hungry unit in the lower tiers. His cover was blown. His anonymity shattered. Grime’s arc welder dropped with a clang. The air in the den grew impossibly still, save for the chilling broadcast. Rook Null was no longer a ghost in the machine. He was the most wanted target in the entire Nexus. And he was standing in a repair shop with a scavenged repairman who had just heard his name, his designation, and the bounty on his head.
