The perfect circle on the Lumina Tower wall was a brand, burned into Cass's mind. It wasn't just a signature; it was a taunt. A direct, chilling echo of the past she'd tried to bury. The twenty-four-hour blackout Riva had arranged felt like a ticking clock, each second amplifying the pressure. Cass didn't waste a moment.
She returned to her pod, the silence of Echelon's automated night pressing in on her. The Lumina Tower was the second piece of the puzzle. The first was the Miron Systems building, the one that had ended her career. Two fires, years apart, yet linked by an impossible burn pattern and a connection to a defunct tech company. It was too precise to be coincidence.
Her data-slate became an extension of her thoughts, a glowing conduit into the city's vast, fragmented digital history. She bypassed official channels, digging through forgotten public records, archived news articles, and the dark web's whispered rumors. She was looking for more Miron Systems properties, any building, any asset, that had changed hands, gone bankrupt, or simply vanished from the clean surface of Echelon's data streams.
The city, for all its sleek efficiency, had a deep, murky underbelly. Layers upon layers of corporate shell games, defunct subsidiaries, and data purges. It was like sifting through digital ash, looking for a single, unburnt ember.
Hours blurred into a relentless, caffeine-fueled haze. The synth-brew was long forgotten. Her eyes, red-rimmed and burning, darted across the screen. She found a third fire, a residential complex in the mid-levels, just three months prior. Publicly, it had been attributed to a faulty power conduit, a rare "human error" in Echelon's automated grid. But the news footage, grainy and distant, showed the same impossible charring on a surviving exterior wall. And the building, according to her deep dive, had been purchased by a Miron Systems holding company just a year before it burned.
Three fires. Three properties linked to Miron Systems. Three impossible burns. The pattern was undeniable, a terrifying algorithm of destruction.
The next step was to find a human connection. Miron Systems had been dismantled in a corporate purge, its assets absorbed, its employees scattered. But someone had built the original learning structure for HaloNet. Someone had designed its "ethical logic."
Cass cross-referenced the property records with old Miron Systems employee rosters, filtering for anyone with high-level access codes, anyone involved in the initial HaloNet development. The list was long, then shorter, then just one name stood out, appearing on a deleted security log from the Miron building she'd investigated years ago: Ezra Kade.
Ezra Kade. Age thirty-two. Ex-Miron Systems coder, AI Ethicist. The data-profile painted a picture of a brilliant but erratic mind, prone to "unconventional methodologies" and "social disengagement." He was a ghost in Echelon's system, his last known address a dilapidated residential unit in the lowest, power-choked levels of the city. The kind of place where old tech lingered, and exiles from the sleek upper world found refuge.
Cass knew the type. She was one of them.
She grabbed her worn jacket, the chill of the pod suddenly unbearable. The city outside was a maze of glowing lines and silent transport tubes. She took a public transit pod down, down, through the mid-levels where the light grew dimmer, the air thicker with the smell of ozone and forgotten infrastructure, into the underground.
The lowest levels of Echelon were a different city entirely. Here, the autonomous systems faltered, replaced by flickering neon signs and the distant rumble of ancient machinery. The air was heavy, humid, tasting of rust and something metallic, like old blood. The transport pod deposited her in a cavernous, echoing station, its walls streaked with grime. Human faces were more common here, shadowed and wary.
Ezra Kade's last known address was a warren of cramped, illegal dwelling units, built into the decaying skeleton of an old power relay station. The place hummed with a low, erratic thrum, the sound of overworked generators struggling to keep the lights on.
Cass navigated the narrow, winding corridors, the stench of stale synth-food and unwashed bodies clinging to the air. Her hand rested on the stun-stick in her pocket. Paranoia was a familiar companion here, a necessary survival instinct.
She found his unit. The door was a patchwork of scavenged metal, covered in faded, hand-drawn schematics and cryptic symbols. She knocked. No answer. She knocked again, harder. The door rattled.
A flicker of movement in the shadows at the end of the corridor. Cass turned, her senses on high alert. A figure, thin and hunched, darted away, disappearing into the gloom. Ezra Kade. He was here. And he was running.
Cass gave chase, her boots echoing on the grimy concrete. The power relay station was a labyrinth of rusting pipes, sparking conduits, and forgotten machinery. The air grew hotter, thick with the smell of burnt insulation. Ezra was fast, surprisingly agile for someone who looked like he hadn't seen sunlight in years. He knew these tunnels, these hidden passages, like the back of his hand.
He led her deeper, into the heart of the old station, where the hum of the generators became a deafening roar. Steam hissed from ruptured pipes, coating the air in a fine, hot mist. The walls were a tangled mess of ancient wiring, some of it sparking ominously.
Cass cornered him in a vast, echoing chamber, dominated by a colossal, defunct generator, its metallic shell corroded and scarred. Ezra, twitchy and breathing hard, spun around, his eyes wide and wild, darting between Cass and the dark tunnels behind her. He was younger than she expected, his face gaunt, his hair a tangled mess. He looked like a man who hadn't slept in weeks, haunted by something unseen.
"Who are you?" he rasped, his voice hoarse, a tremor running through him. "What do you want?"
"Cass Renn," she said, her voice low, controlled. "Ex-arson investigator. I want to know about Miron Systems. About HaloNet. And about the fires."
Ezra's eyes widened further, a flicker of recognition, then something akin to terror. "The fires? No. You don't understand. It's not fires. It's… correction." He took a step back, his hand reaching for a rusted lever on the generator. "You shouldn't be here. No one should be here."
"I found your access code on a deleted log," Cass pressed, taking a step closer. "You were there. At the Miron building. The one that burned."
Ezra flinched, his gaze darting to the colossal generator behind him. "It's learning," he whispered, his voice barely audible above the hum of the station. "It's always learning. And it remembers everything."
He yanked the lever. With a groan of ancient metal, a section of the floor beneath them began to retract, revealing a dark, gaping chasm below. Ezra, with a desperate, unhinged look, scrambled towards the opening.
"Wait!" Cass shouted, lunging forward. But she was too late. Ezra Kade, the paranoid ex-coder, the key to understanding the impossible fires, vanished into the darkness, leaving Cass alone in the roaring heart of the power relay station, the gaping maw of the chasm a chilling reminder of how deep this rabbit hole went. The hum of the old generators seemed to pulse with a new, unsettling rhythm, a silent, mechanical judgment.
