Twenty-four hours later, the ritual was complete. The contract was signed, the vows exchanged in a sterile, minimalist chamber high in the central spire of the stronghold. Miko, dressed in a tailored miniature tunic, had clung to her leg through the ceremony, his small face bewildered by the unfamiliarity. Henrik had watched them both, an intent assessment in his stare that Olenka logged as tactical data. The heir was secured. The marriage, a cold, calculated merger of assets, was legal. Now, three days into their nominal cohabitation within the unfinished compound, Olenka finally had her window. Henrik was engaged in a multi-sector briefing in the tower’s upper echelons, monitored via live feed from her own suite’s holographic display. Miko was confined to his reinforced playroom, attended by a silent mechanical tutor. Olenka had slipped away, her new biometric clearances flowing through the network like oil. Every door yielded. Every sensor array registered her as authorized personnel. The descent was a slow, deliberate drop through the heart of the structure. The lift shaft hummed, pulling her down past layers of hardened concrete and fiber-optic conduits. She emerged into the sub-levels, the air here cooler, thicker with the scent of ozone and polished metal. The subterranean array, a sprawling labyrinth of memory banks and power relays, stretched before her. Moisture glossed the aggregate walls; coolant channels sectioned the floor. Her boots met the anti-static flooring as she traced the trunk line, keying maintenance jacks. The logic bomb was constructed not to ignite, but to unravel the superstructure through stress fractures and controlled ballast releases. It required a final transmission string to prime the charge. She reached the designated vault, a monolithic cube of dark alloy, its biometric lock humming with inert power. A simple palm scan, her newly registered print, and the heavy door retracted with a soft sigh. Inside, tiers of compute blades stretched toward the low ceiling. Olenka moved with fluid precision, accessing the back panel of a central processing unit. Her terminal tablet glowed, displaying an injection payload. The first ping was critical, the initial pulse that would set the entire destructive algorithm in motion. Above, in his suite, Miko pressed his face against the reinforced plasteel window. The machine unit droned through orbital mechanics while Miko studied the ductwork. He caught the flicker of lights along the hallway outside. Boredom was a deep, gnawing beast for a mind like his. He touched a concealed panel in the wall. A holographic interface shimmered into existence. The facility's lighting schematics spread before him, ripe for an override. He wanted to make patterns, bright flashes, like the fireworks he’d seen once in a data-stream. His small fingers danced across the interface, selecting zones, adjusting lumen outputs. A rapid series of pulse commands triggered across the internal grid. He gave a quiet laugh as entire wings dropped into shadow, then flared. One erratic packet burst into the lowest foundation circuits clipped an active intrusion monitor. The internal system logged an anomalous spike, flagging an ingress. The defenses made no distinction between a child's mischief and sabotage. Emergency blast slabs dropped into place. Synthesized audio rang through the passages: “Section Delta-Nine: Access protocol violated. Containment active.” Olenka’s screen chimed an alert. The connection to the central processor severed. The vault door, which had been slowly closing, now shuddered to a halt, then reversed, sealing shut with a heavy thud. Red indicators flared, bathing the memory racks in crimson. She was trapped. Her first instinct was a cold rush of fury. Not at the lockdown, but at the potential disruption to her schedule. Miko. It had to be Miko. Only he could cause such chaos, such an illogical system response. She worked her tablet interface, bypassing local nodes to parse the estate logs. The containment seal was active, not a sensor phantom. Its parameters, however, were too specific for a random event. Her fingers moved across the glass, stripping through the exterior firewall. She needed the raw origin code of the interruption. Her goal was simply to disable it and finish her work. As she burrowed deeper, a secondary data stream caught her attention. It bypassed containment logic entirely, riding the core authentication trunk. A signature she recognized, not as her own, but as Jurgis Vayek’s. She halted. Isolating the stray packet, she forced local processors to strip its hashing. The code unfurled across her screen, line after line of meticulously crafted sub-routines. It wasn’t a simple data tap. Jurgis hadn't just inserted a backdoor. He had spliced his own financial drain into the very architecture of her Reaper Node. His script was timed to fire when her charge cracked the structural supports, bleeding Henrik’s sovereign reserves into offshore blind accounts. Worse, his encryption keys were subtly linked to her own digital signature, framing her and, by extension, Miko, as the architects of not just physical ruin, but financial devastation. “The cunning viper,” Olenka murmured, her voice flat. He wasn’t just extorting her for access; he was setting them up as fall guys, ensuring that even if Henrik survived the collapse, his vengeance would be singularly focused on her and Miko. Jurgis had played her as an expendable asset. She would have to re-calibrate, not just her sabotage, but her entire strategy. Heavy bootfalls echoed through the passage outside. No patrol unit moved with that uneven cadence. A harsh baritone cut through the drone of the hardware. “Olenka! What in the damn hell are you doing in a restricted sector?” Henrik Kordas. He stood at the threshold, keying an override manually. Pneumatics hissed as the containment bulkheads lifted. The screens beside her still pulsed with Jurgis’s mirrored script. The vault door finally retracted with a groan of stressed hydraulics, revealing Henrik Kordas standing in the threshold. A hard vein stood out along his throat, his expression fixed in razor-sharp appraisal. He took in the warning beacons, the open service terminal, and the tablet in her grip. Olenka met his gaze, unflinching. Jurgis's payload flashed across her screen, an open indictment. Her mind raced, discarding dozens of lies, searching for the one truth that would serve her. The one truth that would turn his fury into something else entirely. She closed the datapad, her expression hardening into resolute conviction. She looked Henrik dead in the eye, her voice clear and precise. “I was looking for the man trying to kill our son.”
