The scalpel sang a thin, eager note as Oyuun sliced through the reinforced polymer seal. Zenith Spire’s central hall, a cavernous space of burnished cromium and pulsating bio-conduits, thrummed with the low, constant hum of the continent’s most advanced xenobiological inquiry. She paid it no mind. The anonymous courier parcel, a plain grey brick, held more urgent fascination than the distant roar of a caged Grond-Behemoth being prepped for the Conclave’s first live-fire surgical exam. “Oh, marvelous,” she murmured, peeling back the last flap. Inside, nestled on a bed of shimmering biogel, was a pulsating, iridescent mass. It wasn’t quite an organ, not yet. More a raw, unformed possibility, veined with violet and viridian, subtly contracting as if dreaming of a host. A sharp, metallic clang echoed across the concourse, drawing a ripple of attention from the passing Surgeon-Khans and their armored warrior retinues. Oyuun barely registered it, her gaze locked on the shimmering specimen. It was exactly as described in the fragmented data-packet she'd bribed a Port-Khagan to deliver from the furthest fringes of the Ash-Wastes. “Oyuun?” The voice was a rough rasp, laced with disbelief, a sound she hadn’t heard in years. Oyuun looked up, her bright, inquisitive eyes blinking at the interruption. Temur stood a dozen paces away, his formidable combat chassis gleaming under the harsh overhead glow. He looked... larger, somehow. More weathered. And beside him, clinging to his arm like a delicate vine, was a woman with hair the color of dawn frost and eyes like polished obsidian—the stand-in named Kaelis. Temur swallowed dryly, his gaze sweeping over Oyuun’s surgical scrubs, the scalpel still clutched in her hand, the open container. “You’re… you’re back. I… I thought you were gone. For good.” His voice was a thick, uncertain rumble, the kind she remembered from before the war, before the rot, before the Conclave applications. Before he’d decided she wasn’t worth waiting for. Oyuun tilted her head, a cheerful, almost blinding smile spreading across her face. “Gone? My dear Temur, a dedicated scientist never truly ‘leaves.’ Merely relocates for fieldwork.” She gestured vaguely towards the container. “In fact, your timing is impeccable. I was just about to log my initial findings.” She took a step closer, the rhythmic thrum of the Spire seeming to intensify around them. Temur visibly flinched, the companion tightening her grip on his arm. “Fieldwork?” he managed, his brow furrowed with confusion, or perhaps a dawning apprehension. “What are you talking about?” “Why, my thesis, of course!” Oyuun chirped, holding up a finger. “The efficacy of emotional trauma as a catalyst for cellular regeneration in biomechanical grafts. Specifically, the physiological and psychological impact of sudden abandonment and perceived romantic betrayal on the host’s ability to integrate foreign tissue. A fascinating area, truly.” Temur’s face drained of color. The stand-in, too, looked as if she’d swallowed something bitter. The onlookers, sensing the shift in the air, slowed their pace, their gazes flicking between Oyuun and her ex-fiancé. “You see,” Oyuun continued, her voice light and analytical, “I needed a reliable baseline, a control group. Someone whose baseline parameters I intimately understood, someone whose emotional response to a specific stimulus I could accurately predict and monitor over an extended period. And who better than a close acquaintance?” Her smile didn’t waver. “Thank you, Temur. For being so reliably… predictable.” The silence stretched, thick and suffocating. Temur opened his mouth, but no sound emerged. His consort looked like she wanted the chromite floor to swallow her whole. Oyuun reached for a comms unit clipped to her belt. “Zenith Spire Medical Authority,” she stated, her tone brisk, “this is Surgeon-Prodigy Oyuun. Requesting instant de-authorization of all Level-Gamma and above medical access for warrior designation Temur of the Sunstone Legion. Reason: Subject deemed unsuitable for advanced biomechanical integration due to compromised emotional stability and potential psychological interference with critical graft procedures.” She paused. “Effective on the spot.” A disembodied voice crackled from the unit. “De-authorization confirmed. Subject Temur, all Level-Gamma medical privileges revoked. Please exit Zenith Spire without delay.” Temur swayed, a hand reaching instinctively for his chest where his upgraded power core hummed. “You… you can’t do that,” he rasped, his eyes wide with a desperate, wounded disbelief. “My armor… my upgrades…” “Oh, I assure you, I can,” Oyuun said, her smile fading into a look of genuine, if detached, pity. “Don’t worry, darling. Your stand-in looks thoroughly capable of handling the more mundane maintenance. Now, if you’ll excuse me, my duties await.” Before Temur could form another choked protest, a new voice, sharp and precise as a laser scalpel, cut through the tension. “Surgeon-Prodigy Oyuun, what in the Rot-Damned Spire do you think you’re doing?” Bayan. His approach was as meticulously ordered as his perfectly combed dark hair, his surgical robes pristine. He moved with an almost aggressive efficiency, his eyes, the color of storm-swept tundra, fixed on the package in Oyuun’s hands. “An unauthorized bio-courier delivery? Containing an unscheduled xenobiological specimen? In the central rotunda?” He practically spat the words, each one a violation of protocol. “Hardly unauthorized,” Oyuun retorted, rolling her eyes. “A highly anticipated specimen, delivered with the utmost discretion. The Spire’s mail system is abysmal, Bayan. I had to improvise.” “Improvise?” Bayan scoffed, reaching for the package. “This is a level-seven breach of protocol! Surrender the crate. It will be quarantined and analyzed properly, under sterile conditions, by a *licensed* team.” “And miss the initial ex-situ observations? Never!” Oyuun pulled the box back, just out of his reach. “Besides, it’s far too delicate for your ham-fisted methodology, you academic brute. I suspect it requires a… gentler touch.” Their bickering was a familiar duet, a rapid-fire exchange of scientific jabs and personal insults. Bayan’s hand shot out again, quicker this time, snatching the carton from Oyuun’s grasp. He held it up, his expression a mixture of triumph and disdain. “See? Precision,” he sneered. “Now, if you’ll forgive me, I have actual, *sanctioned* fieldwork to conduct, unlike your…” Before he could finish, the iridescent mass within the box pulsed once, violently. The biogel shivered. A low, guttural thrum vibrated through the air. Bayan drew back his chin, a flicker of genuine alarm replacing his usual arrogance. The box bucked, the reinforced polymer cracking with a series of sharp reports. The iridescent organ inside, suddenly no longer dormant, spasmed. It lunged.
