The Republic of Kravat’s divorce proceedings were as grim and efficient as its steel infrastructure. Revna Kholis traced the grime on the faux-velvet chair with a detached finger, the air in the minor magistrate’s office thick with the scent of recycled ozone and stale ink. Outside, the perpetual smog of the capital pressed against the grimy ferro-glass, blurring the towering, brutalist spires into indistinguishable shadows. She barely registered the scratch of the stylus as her ex-husband, Tavish Yorn, scrawled his name across the final document. “Done,” Tavish announced, his voice a low thrum of self-satisfaction. He was all sharp angles and tailored ambition, his military-grade coat still smelling faintly of the Velkarn Proving Grounds. “Finally free of this… millstone.” He didn’t bother to hide his sneer. “Five years. Five years of you doing nothing but collecting dust, Revna. Now, I can finally focus on what matters. My contracts with the Thyrn Collective are about to be finalized. Significant strategic weapon patents, you understand. Things far beyond your comprehension.” Revna offered a faint, almost imperceptible smile. “My comprehension has rarely been an issue, Tavish. Only my tolerance.” Her voice was a low rasp, tinged with a weariness that had been five years in the making. She signed her name, a fluid, elegant script that belied the cheap paper and the squalor of the room. The magistrate, a skeletal woman with permanent dark circles beneath her eyes, stamped the documents with a perfunctory slap. “The settlement is generous, considering,” Tavish continued, entirely ignoring her. “Enough for you to fade into obscurity in some outlying district. Just don’t embarrass me. The Thyrn Collective values discretion.” He rose, adjusting his cuffs, his gaze sweeping over Revna with an air of absolute dismissal. He regarded her like a spent shell casing, once functional, now scrap metal. “I wouldn’t dream of it,” Revna murmured, watching his tailored back recede. The heavy, reinforced door thudded shut behind him, the sound echoing through the sterile hall. Almost immediately, a figure detached itself from the shadows near the hall’s exit. A courier, impossibly pale, with eyes that seemed too wide for his face, moved with a disturbing quietness. He wasn’t wearing the standard Kravat postal uniform; his attire was a simple, unmarked grey tunic. He approached Revna’s desk, placing a single, matte-black cylinder before her. It was heavy, cool to the touch, sealed with an unmarked wax sigil. He didn’t speak. He simply inclined his head, a gesture devoid of emotion, and then melted back into the shadows as silently as he had appeared. Revna’s fingers brushed the smooth, cold surface of the cylinder. A faint hum, like dormant power, seemed to emanate from it. She broke the seal, the wax crumbling to dust. Inside, nestled against a tightly rolled schematic parchment, lay a single, folded letter. Her own handwriting, unmistakably. The date scrawled at the bottom made her pause: five years ago. The day before her wedding. The letter was short, stark, and utterly chilling. *“Revna, if you are reading this, the trap has been sprung. You chose to forget. Do not mourn the loss; embrace the weaponization of your own memory. Tavish Yorn is a cancer. Erase him. Cipher: Kholis_Null_Grid_Omega. Your alias: Zero. The design details the first phase. Your past self demands retribution.”* A cold, calculated amusement unfurled in Revna’s chest. She had erased herself, not from weakness, but to become a ghost haunting her own future. A doomsday sequence, triggered by her own arranged amnesia. It was a twist so exquisitely cruel, so perfectly *her*, that a genuine, if dry, laugh escaped her lips. She pulled a cheap, battered terminal slate from her worn satchel, its screen cracked in one corner. Ignoring the intricate lines of the parchment for a moment, she entered the cipher. The handheld whirred, its low-grade processor struggling for a moment before a stylized ‘Z’ shimmered onto the screen. Beneath it, a single command prompt blinked. `>> Target: TavishYorn.Comms.Private.Network` Revna’s fingers flew across the worn keys, a blur of motion. She did not hesitate; each keystroke struck with cold mathematical malice. A tiny, dry *click* ticked from the housing, faint as an insect bite, yet across the district, high-tier relays flared out. Across the city, Tavish Yorn’s personal comms network, encrypted with military-grade protocols, spontaneously combusted into a shower of dead data packets. Bricked. Irrevocably. A sense of quiet satisfaction settled over her. A phantom designer’s first move. The amusement deepened. Tavish was likely already cursing the incompetence of his tech department, entirely unaware that his discarded ex-wife had initiated his collapse from an off-the-rack slate. “Having fun with your little toy, Revna?” A new voice cut through the courthouse’s oppressive quiet. Braya Neth, Revna’s fiercely loyal best friend, leaned against the doorframe, her posture radiating an effortless danger. Braya’s dark, close-cropped hair framed a face that was all sharp angles and watchful eyes, a coiled predator in civilian clothing. Her gaze flickered to the black cylinder, then to the screen. Before Revna could respond, Braya shifted, her movement fluid, barely perceptible. A dark-clad figure, who had been lingering near the entrance to the hall, suddenly stumbled. He wore the insignia of the Grath Syndicate, a low-tier cyber-crime organization often used for petty intimidation. One moment he was leaning against the wall, attempting to look inconspicuous; the next, he was on his knees, a short, sharp gasp escaping him before he slumped forward, unconscious. Braya straightened her jacket cuff, brass-wrapped knuckles catching the dim gaslight. “He was getting irritating,” she said, her tone utterly casual. “Always so predictable, these thugs.” Revna lifted an eyebrow. “Efficient, as always.” She unrolled the blueprint, spreading it across the dusty magistrate’s desk. It was a dizzying array of schematics, power conduits, and complex cybernetic overlays, all centered on a massive, grid-like structure. The sheer scope of it was breathtaking, even to her. Braya walked over, her eyes narrowing as she took in the intricate lines. Her usual detached calm fractured, replaced by a stark, unnerving pallor. Her gaze snapped from the blueprint to Revna’s face, a tremor in her usually steady voice. “Revna… this is the trigger for the Velkarn Grid. You swore you burned these schematics.”
