Ryzalia clutched the sabotage explosive, its cold, smooth surface a stark contrast to the rough metal of her old workshop. The harmonic thrum vibrated faintly against her palm, a whisper of engineered destruction. She didn't hesitate. The Hext Syndicate Spire, a needle of obsidian and braided flux filaments, loomed against the bruised sky when her skiff docked. She bypassed the debriefing bays, heading straight for her lab, the explosive protected in a custom Faraday cage she'd fashioned mid-flight. Isken Varga was already there, hunched over a holoscreen displaying a complex energy signature analysis. The lab hummed with the quiet thrum of hyper-processors, the air cool and sterile. He looked up, his sharp eyes narrowing as she approached, the cage in her hand. “Took you long enough. Kylian’s broadcast is set for forty-eight hours. Did you at least manage to not get yourself filleted by his goons?” “Wipe that smug look off your face, Varga,” Ryzalia retorted, setting the cage down with a soft *thunk*. “My return was a tactical triumph, not a scramble. And I brought a souvenir.” She opened the cage. The small cylinder gleamed under overhead luminophores, its alloy reflecting polished steel around it. Isken straightened, his gaze locked on the artifact. “What in the Zenith…?” “It’s an engineered demolition charge,” Ryzalia explained. “Found it in the wreckage of my old workshop. Designed to bypass detection arrays, uses a micro-cell for power, and the harmonic frequency…” She paused, watching his reaction. “Matches the exact waveform Voldir Hext has hunted for a decade.” Isken reached for a pair of mag-force manipulators, his movements precise as he lifted the canister. He moved it to a diagnostic array, his fingers flying across a touch-panel. Holographic schematics bloomed in the air, detailing its intricate internal structure, an inertia amplifier, and a miniaturized pulse emitter. “This isn’t just high-grade, Morcrest. This is bespoke sabotage. The Ghost’s calling card.” Ryzalia stepped closer, studying the rotating schematics. “The Ghost? I’ve heard rumors. A phantom saboteur who made entire corporations vanish overnight a decade ago. But he disappeared, didn’t he? Everyone thought he was a myth.” “Not a myth,” Isken muttered, his voice stripped of its caustic drawl. “A ghost who leveled three rival firms without leaving a trace. This pulse variant drops substation relays and comms without scratching load-bearing struts. Surgical.” He zoomed in on a micro-etching near the power cell. A stylized, almost artistic 'K' was barely visible. “A K… as in Kylian?” Ryzalia touched the edge of the holoscreen. Her brother, hailed as the Zenith District's pristine prodigy, running black-market demolition? Before Isken could respond, a shrill, piercing alarm ripped through the lab. Overhead tubes died, plunging them into sudden gloom. Emergency red strobes pulsed erratically, casting grotesque shadows. “Ion burst!” Isken barked, setting the cylinder down onto a cushioned bench. “A remote trigger tripped the localized coil. It's a fail-safe.” A harsh mechanical whir dropped from the intake shaft. Two compact hunter drones dropped onto the sub-deck, optics burning dull red. Kylian’s clean-up crew must have hitched a ride on her skiff’s undercarriage from the Rust-Steppes, waiting for the blackout signal. “Stay low, Morcrest!” Isken yelled, drawing a compact energy disruptor from his belt. Its blue muzzle flash briefly illuminated the first drone as he fired, scorching its metallic carapace. The drone shrieked, its rotary blades churning, and fired back—a searing beam of plasma that missed Isken by an inch, carving a smoking furrow into the wall beside him. Ryzalia didn't need telling twice. She dove behind a reinforced terminal desk, digging into her tool kit. The second drone descended, aligning its bore with her chest. Isken shoved her flat beneath the steel ledge. The plasma beam sliced through the air where her head had been, then slammed into Isken’s shoulder with a sickening *CRACKLE*. He cried out, a sharp, guttural sound, stumbling back, clutching the smoking wound. “Isken!” Ryzalia hauled him down by his collar. The smell of scorched wool and flesh hit her throat. He'd thrown himself directly into the firing line for her. She grabbed a handful of high-tensile data cables and, with a swift, practiced motion, shorted a nearby power conduit. Sparks flew, momentarily disorienting the first drone. While its gyro spun, she hurled a stripped conductor coil at its glass lens. The drone shrieked as its vision shattered, careening wildly into the second drone. Tangled, disoriented, they became a single, thrashing target. Isken, gritting his teeth, fired his disruptor, tearing through their combined forms. They exploded in a shower of sparks and molten shrapnel, their metallic husks clattering to the floor. The EMP field dissipated. Primary fixtures hummed back to life, flooding the tile with stark white illumination. The air smelled of ozone, burnt metal, and something acrid—Isken’s seared flesh. He slumped against the terminal housing, hand clamped over a crater of burned fabric and blackened flesh. Blood, dark and viscous, welled between his fingers. Ryzalia dropped beside him and ripped the hem off her tunic, packing it into the breach. Isken’s ribs hitched. “You handle scrap-iron better than advertised, Morcrest,” he rasped, blood flecking his lower lip. “Shut up, Varga,” she muttered, pulling an dermal sealing spray from the wall rack. Foam hissed across the cauterized tissue. Her fingers trembled against his collarbone, soot smearing across his neck. His pupils contracted, watching her hands work without his usual barbed sneer. “The mark on the casing,” Isken said, breaking the silence. “Kylian. It makes horrifying sense. His rapid ascent, his impossible ‘innovations’… he didn’t invent them. He stole them, or destroyed the competition. The Rust-Steppes array he’s about to power up on the national broadcast? That Kinetic-Weave core belongs to you, but he filed under his own seal.” Ryzalia nodded slowly, the pieces clicking into place with a sickening finality. “He needed a way to consolidate power, eliminate rivals. If he was the Ghost, he’d have the connections, the resources, the sheer audacity to pull it off. He always had a flair for the dramatic, even as a child.” A deep, resonant voice cut through the aftermath, cold and devoid of warmth. “Indeed.” Ryzalia and Isken looked up. Voldir Hext stood in the lab threshold, his silhouette framed against the corridor. His gaze swept over the wrecked drones, the charred desk, the blood seeping through Isken’s fingers, and settled on the cylinder resting on the bench. The billionaire stepped forward across the broken glass, hands clasped behind his back, stopping inches from the charge. “That signature…” Voldir said, his voice flat, dangerously quiet. He looked up, his gaze fixing on Ryzalia, then Isken, then back to the device. “Your brother is the one who murdered my wife.”
