The clinic AI’s synthesized drone rattled through Marenna’s molars: an automated balance sheet demanding she yield to Virek Nall. Two options presented themselves across the polished stone: surgical extraction of the gestational payload, or letting the CEO bleed out through his ruptured tactical weave. The network calculated only the optimal incubation trajectory, ignoring debts and hostile takeovers alike. “Optimality be damned,” Marenna muttered. Garreth Hyle, despite his calculated possessiveness, had intercepted a beam meant for her spine. The act defied contractual logic. It was an unauthorized structural variance, the sort of unstable load-bearing choice that usually collapsed an entire bulkhead. She dropped to her knees into the warm puddle beside his ribs. The vault door was a solid slab of reinforced plasteel designed for containment rather than egress, but every sealed box required circulation: maintenance conduits, pressure equalization shafts, filtration manifolds. Her subterranean training shifted from basalt fractures to the penthouse's utility layout. “Garreth,” she said, shaking his shoulder. His eyes, glazed and distant, fluttered open. A weak cough rattled his chest, more pink foam bubbling at his lips. “We’re moving. Now. Where’s the nearest unmonitored service shaft?” He managed a pained chuckle. “Trust a Thrace to look for the back door in a secure facility.” His hand, surprisingly strong despite his fading strength, gripped her wrist. “Sub-level six. Filtration manifold. Code… Zygote-Echo-Seven. Access… from corridor maintenance panel… north wall… behind fire suppression array.” His voice faded, his grip slackening. Brick, who had been gnawing furiously on the mercenary’s incapacitated groin, finally released his victim with a disgusted whine. The gargoyle-pug trotted over, snuffling at Garreth’s face, then let out a low, mournful growl, thick fur bristling. His concern, Marenna noted, was entirely inconvenient. “Good dog,” she said, an unfamiliar note of something soft in her voice. “Guard him.” “No,” Garreth rasped, his eyes locking onto hers with surprising intensity. “You… guard yourself. Virek… expects… you.” His head slumped back against the cold tile. Unconsciousness was a mercy she couldn’t afford him yet. Marenna took a deep, fortifying breath, the stench of ozone and fresh blood filling her lungs. “Brick, cover.” The pug immediately positioned himself between Marenna and the vault door, a shaggy, snarling barricade. His aggressive shedding accelerated, creating a defensive cloud of bio-engineered dander. Garreth, she realized, was heavy. Not just physically, but with the dead weight of a man whose body was quickly shutting down. Her pregnancy, a constant, low thrum beneath her ribs, made the effort doubly challenging. “Right,” she grunted, leveraging her shoulder under his armpit. “If I collapse, the fetus might get jostled. Unacceptable. We keep moving.” She dragged him, a painstaking inch at a time, toward the opposite wall, her eyes scanning for the “fire suppression array” Garreth had mentioned. Her every muscle screamed in protest. The medical AI continued its unhelpful refrain, a siren song for surrender, each repeated syllable a fresh spike of irritation. Marenna spotted a recessed panel flush against the plasteel. Her knuckles, calloused from years of subterranean surveying, traced the hairline seal. [ALERT: PATIENT MARENNA THRACE. HEART RATE CONTINUES ELEVATION. COMPLIANCE WITH SURRENDER PROTOCOL RECOMMENDED FOR OPTIMAL FETAL OUTCOME.] “Shut up, you glorified spreadsheet,” Marenna hissed, pulling a thin shim from her wrist-comp’s utility slot. She worked with practiced speed, the small tool sliding into the panel’s lock mechanism. A soft click. The panel swung open, revealing a tangle of conduits and, more importantly, a narrow, dark shaft descending into the clinic’s forgotten depths. The air was cool, stale, and blessedly free of the AI’s nagging voice. “Sub-level six, here we come, Hyle,” she muttered, starting the slow, agonizing process of lowering Garreth’s inert form into the shaft, then sliding in after him. Brick, with surprising agility for his bulk, squeezed in behind them, a furry, growling shadow. They descended through the grimy network of service tunnels, the sounds of the distant siege echoing faintly above them. Marenna’s internal compass, honed by years of navigating uncharted rock formations, guided them through the maze of pipes and wires. Garreth stirred occasionally, a low moan, a desperate cough. His breathing was shallow, his skin alarmingly cold. Eventually, she found a small, unused junction box – a forgotten node in the clinic’s vast network. Perfect for a quick hack. She propped Garreth against a grimy ventilation duct, his chest rising and falling in shallow, ragged gasps. Brick immediately curled up against him, a warm, shedding sentinel. “Don’t die on me now, Hyle,” she whispered, pulling out her wrist-comp. “The syndicate still needs their payment, and I still need to ruin your monopoly. Dying is not an option.” She keyed through the holographic interface, bypassing local security protocols to establish an external line to Garreth’s private security dispatch. She needed his elite extraction team, the ones who handled the 'unforeseen corporate acquisitions' his business was infamous for. The task, usually complex, felt like child’s play compared to dragging a comatose billionaire through a vent system. Then, a peculiar file caught her eye. It wasn't an operational log or security schematic, but a heavily encrypted medical folder, marked with the Apex Spire’s highest privacy cipher. The file name: `Cort, Sybilla – Marrow-Rot Protocol: Phase Gamma`. Marenna hesitated. This was not part of her mission parameters. This was an intrusion, a breach of privacy for a woman she actively disliked. But her pragmatic curiosity, a relentless hunger for information, overruled her ethical qualms. She initiated a rapid decryption sequence, her wrist-comp humming with effort. The file, stubborn and layered, slowly yielded its secrets. Within seconds, she processed the telemetry. A lethal, aggressive form of skeletal decay. Prognosis: fatal without an exact, genetically synchronized cord blood transfusion. The biological timetable was critically narrow, and the only matching stem-line matched the fetal profile currently developing in her own uterine wall. Marenna’s hands hovered above the projector. Sybilla Cort. The demanding fiancée who sneered at Marenna's presence was not pursuing an heir purely for dynastic leverage. She was dying, and Marenna was incubating the singular cellular cure. Before Marenna could fully digest the implications, a new set of footsteps echoed down the shaft. Not Nall’s lumbering enforcers, but light, precise movements. A faint hum of high-tech gear. Garreth’s team. And leading them, a silhouette Marenna recognized immediately. Sybilla Cort. Her usually impeccable hair was slightly dishevelled, a thin smear of grime on her cheek. But her eyes, even in the dimness, held a feral glint that was anything but glamorous. “Thrace,” Sybilla’s voice was low, stripped of its usual clipped superiority. She knelt beside Garreth, pressing two knuckles against his carotid pulse. “He’s losing pressure.” Marenna didn't reply, her mind reeling from the file. Sybilla, sensing the shift, turned to her. The mask of the icy, demanding fiancée began to crack. “You found it, didn’t you?” Sybilla’s voice was flat, devoid of its usual venom. “My file.” Marenna nodded, keeping her voice even. “Skeletal necrosis. Terminal. The fetus is your only compatible donor.” Sybilla rested against the conduit casing with a short, humorless exhalation. “Years ago. Garreth overextended his perimeter during an acquisition in the old Veridian Sector. I dragged him through the breach and caught a stray bio-bomb fragment. The rot is a systemic degradation. I’ve been running on experimental immunosuppressants that barely slow it down.” Her elegant facade crumbled, revealing raw desperation. “I don’t want this child for a damn throne, Thrace. I want to *live*. Virek Nall knows. He’s been tracking my health markers for months. He knows the cord blood from your fetus is the only cure.” Sybilla fixed her with a sharp, fevered stare. “If Nall secures that child, he won't just hold Garreth hostage. He will withhold the cord tissue until my organs fail. Then he steps into the vacuum, offering Garreth his own daughter to bind the conglomerates over my grave.” Marenna stared, the cynical gears of her mind grinding to a halt. The villainous fiancée. The icy CEO. The ruthless industrialist. It wasn’t a simple kidnapping. It was a meticulously crafted web of power, betrayal, and a very personal, very deadly, biological clock. “Garreth doesn’t know, does he?” Marenna asked, the words hollow. Sybilla’s gaze dropped to her hands. “No. He thinks… he thinks I’m fine. He thinks I want this heir for corporate vanity, just like everyone else. He doesn’t know that Virek Nall is planning to let me expire, so he can marry his own daughter to Garreth and take everything.”
