“Tasia!” Yvaine gasped, a strangled sound, taking an involuntary step forward. Corvin’s hand shot out, clamping around her arm, pulling her back with a force that bruised. “Don’t approach,” he commanded, his voice sharp, devoid of his usual mocking lilt. “The aura around her… it’s a living void. It will tear you apart.” His eyes, usually glinting with detached amusement, were narrowed, focused on his sister’s shuddering form. The wings, still expanding, scraped against the low ceiling, shedding flakes of dark, powdery dust that dissolved before they hit the floor. Tasia’s head lolled, her eyes rolling back, revealing only whites. Corvin scanned the lobby, his mind racing. “We have to seal this place.” He dragged Yvaine toward the shattered reception desk, his gaze already calculating angles, structural integrity. “The pressure wave from that eruption… it will draw more of them.” He nodded toward the stairwell leading down to the sub-basement, a faint, metallic tang still clinging to his scrub trousers. “The big ones.” He released Yvaine, then began tearing through the counter alcove with controlled fury. Filing cabinets were upturned, vinyl chairs stacked, anything heavy dragged to block the main entrance. The thick glass doors, already webbed with cracks from Tasia’s earlier assault, were reinforced with a barricade of salvaged office consoles. He pried an ornamental bronze donor plaque from the plaster, wedging it against the final seam. His movements were precise, unhindered by the tranquilizer’s lingering numbness. If anything, the sedative had sharpened his focus to an icy edge. “What are you doing?” Yvaine demanded, clutching her arm where he’d held it. Her gaze flicked from Tasia, now writhing slowly on the floor, the wings spasming with unholy life, to Corvin’s frantic barricading. “We need to drag her into an isolation room, not… not trap her in here!” “A trauma unit would be ripped apart,” Corvin retorted without looking at her, grunting as he wrestled a heavy monitor stand into place. “And then she’d be nothing more than a fresh feast. This isn’t a medical emergency, Yvaine. This is a containment breach.” He finally straightened, surveying his makeshift fortress. It wouldn’t hold forever, but it would buy precious minutes. He then turned his attention to the laminate counter itself, sweeping away scattered medical charts and shards of baked clay. “The demon core. The rat blood. The mold from the sub-basement.” He rattled off the list, his voice calm, even as his sister’s wings stretched, tearing more holes in her gown. “Gather everything. Quickly.” Yvaine, despite her revulsion, moved quickly. She retrieved the small, crystallized core from Corvin’s pocket, its black facets catching the amber emergency tubes. The vial of rat blood, faintly luminescent with miasmic energy, was set upon the laminate. The small, sealed plastic bag containing the iridescent fungal scrapings joined them. Corvin produced a small, silver-bound grinding bowl and pestle from an inner seam—a relic from his world, carried across the void, still smelling faintly of cinnabar and dried nightshade. He began to work, his motions fluid, almost ritualistic. The demon core was crushed first, grinding into a fine, obsidian powder. The rat blood, then, was added drop by drop, each crimson bead dissolving into the black dust with a faint sizzle. He murmured incantations under his breath, ancient syllables that vibrated in the sterile air, completely out of place. The mold, finally, was introduced, blending into the paste, which simmered with a sickly, phosphorescent green radiance. The air shimmered, the scent of ozone intensifying, replaced by something sweet, metallic, and profoundly ancient. “It’s almost ready,” Corvin said, his voice softer now, devoid of its usual edge, almost… weary. He stared at the luminous slurry in the stone bowl, the viridian gleam caught against his irises. “The Primordial Panacea.” Yvaine leaned closer, mesmerized by the unholy alchemy. “Then… then you can save her?” Her voice was thin, hopeful. Corvin drew a low, ragged breath. He looked up at Yvaine, his usual sneer fading into blunt gravity. “To purge this stage of the Rot… the true, advanced form… requires more than mere reagents. It demands a binding agent.” His gaze drifted to Tasia, who let out a guttural hiss, her wings twitching violently against the tiles. “A grandmaster’s core vitality.” Yvaine frowned. “What do you mean? What kind of binding agent?” His eyes met hers, stark and resolute. “I mean, it needs *my* cultivated essence. To burn away the rot that has rooted into her marrow. To wrench her spirit back from the pit.” His voice remained even, flat. “I feed it to her, and my meridians collapse.” The bright brew pulsed in the stone dish, casting green light across his hollow cheekbones. He did not look away. “It is the sole method, Yvaine. The Rot is too deeply entrenched. The compound requires an etheric reservoir, an anchor strong enough to hold her soul. I am that anchor.” “No,” Yvaine whispered, her voice thin. Her mind scrambled through diagnostic pathways, seeking any alternative. The black veins beneath the skin of her left wrist: faint, pencil-thin lines of creeping rot. An active link. An inverted circuit. Instead of expending his soul, her own blighted tissue could serve as an alternative conduit. A shared resonance. “Your cultivation,” Yvaine said, stepping in until her boots grazed his slippers. “My infection. It’s in the incubation phase. It ties me to the Rot, but through the pathogen, it ties me to your work. To this cure. It can be inverted. It can serve as the etheric bridge without burning out your core.” Corvin stared at her, a flicker of something unreadable in his gaze. “Impossible. It would tear you apart. You are not a grandmaster.” “No, but I’m infected. And I’m right here.” She made a decision, a reckless, terrifying leap of faith. She wouldn’t let him sacrifice himself. Not now. Not when she had just begun to understand him, to see past the masks. “You need a vessel. I will be your vessel.” Before he could protest, before he could even utter a syllable, she moved. Driven by a surge of adrenaline and a fierce, protective instinct she hadn’t known she possessed, Yvaine grabbed Corvin’s face with both hands, pulling him toward her. Her mouth, cold and tasting of dust, pressed hard against his. She forced the contact not out of tenderness, but as a deliberate short-circuit across raw channels. Her intent remained ruthless: bridge their meridians, force a pathway, bleed off the backlash. Static crackled between their teeth, a piercing shock that burned the nerves in her tongue. His stare fixed on hers in harsh realization as the reflux ignited. The viridian mixture in the mortar surged, its rhythm snapping into a violent boil. The transfer slammed shut like an iron gate. The Primordial Panacea settled, gleaming like crushed emerald. But the surge of power, sudden and immense, was too much for the already stressed surroundings. A low, vibrating hum began, deep and resonant, rising from the very foundations of the Bleakmoor. The lobby windows, already rattling from Tasia’s earlier outburst, suddenly shattered outwards in a violent explosion of glass shards, spraying across the rain-slicked grounds. The air outside, thick with the perpetual drizzle, became unnaturally still, then began to coalesce into dark, swirling patterns just beyond the broken panes, drawing itself up from the city’s unseen depths. A vast, unseen consciousness, ancient and terrible, had woken. And it was coming for them.
