The air around them thrummed with a low, malevolent hum. Branka didn’t wait for Mirkov’s command. She caught Stoyan by the elbow, hauling him into the Aviary’s central transit shaft while Gavril vaulted ahead of them, skin bloodless. The copper bite of ozone scraped her tongue, mixed with the sulfurous grit of the external smog seeping past the pressure seals. The transit tube's pneumatic hiss felt like a shallow gasp as it swallowed them, hurtling them upwards through the earth, towards the heart of the catastrophe.
They burst into the Zlata Plaza, not a grand, bustling square but a desolate ruin. The once pristine, translucent dome of the Crucible arena was a grotesque, bulbous sac, distended and churning with the dense, clotted haze. Deep purple and viridian clouds roiled against its curved surface, thick as clotted blood. The aristocratic spires, usually gleaming against the filtered sky, were now obscured, spectral silhouettes against an apocalyptic canvas. The air was a heavy, suffocating blanket, each breath a struggle. Branka felt the poison settle in her throat like crushed glass, rattling against the auroral warmth dormant under her ribs.
“He’s using the arena’s sound baffles to amplify the parasite’s frequency,” Gavril gasped, pointing to massive, skeletal pylons ringing the dome, now pulsing with an unnatural, sickly green illumination. “He’s making it resonate. To spread it… everywhere.”
The ground shuddered again, a more violent, sustained tremor. One of the colossal ornamental pillars, carved with the forgotten sigils of ancient alchemists, groaned above them, a crack spiderwebbing across its base. It began to topple, a slow-motion avalanche of carved stone and ancient dust, directly towards Gavril.
“Gavril!” Branka screamed, her hand instinctively flaring with nascent auroral light. There was no time for her to weave a barrier. Gavril, however, reacted with a desperate grace. He slammed his palm down on his bracer. A burst of iridescent, pearlescent material erupted, expanding into a convex, shimmering shell just as the pillar struck. The impact was deafening, a sickening crunch of stone against an unseen barrier. The iridescent carapace held, screeching under the mass, fractures threading across its curve like spider silk. Gavril dragged himself clear as the masonry settled, the alchemical bulwark collapsing with a hiss of discharged vapor. He caught Branka's gaze with a stiff nod; she had fitted that valve onto his bracer only three nights ago.
Stoyan, however, was not so fortunate. He stumbled, a harsh, wet cough wracking his frame. His hand flew to his chest, clutching at his tunic as if to contain something bursting forth. A thin trickle of black, viscous fluid escaped the corner of his mouth, staining his lip. His grey eyes dulled to wet slate, nostrils flaring as his throat seized. The dense, contaminated air hurried the rot through his veins. His dormant parasite, the very thing Ivanek sought to inoculate the world against, was waking within him, tearing at his insides.
“The frequency… it’s disrupting my equilibrium,” Stoyan choked out, sinking to one knee, his body wracked with tremors. Each breath was a shallow, painful gasp. The black rot that already consumed parts of his skin seemed to deepen, to spread in real-time, dark tendrils reaching for his throat, his eyes.
From the shattered arena floor, a silhouette resolved through the drifting sulfur. Lord Ivanek. He stood before a massive, pulsating console, his expression a grim satisfaction. A low hum emanated from the console, growing in intensity, a sound that vibrated deep in Branka’s teeth, in her very bones. He leveled an amber prism, its core thrumming with contained lightning, directly at their chests.
“The world must be saved, Catalyst,” Ivanek’s voice boomed, amplified by the arena’s systems, cutting through the din of the storm. “Even if it resists.”
Branka felt a primal scream build in her throat. The crystal flared white, releasing a razor-thin needle of high-frequency percussion. It wasn’t aimed at Gavril, or even Branka. It was arcing directly for Stoyan, who was still gasping, struggling to rise.
Without a thought, without a shred of hesitation, Stoyan launched himself forward. Not away, but *towards* Branka, towards the path of the lethal sonic strike. He threw his torso between the searing beam and Branka, arms splayed. The force struck him full in the chest, not with a sound, but with a sickening, internal implosion. His gaze locked onto Branka's before his knees folded, a spray of black bile bursting across his chin as he hit the tiles.
Ivanek, tall within the swirling purple haze, lowered the prism. The hum of the arena amplifiers died down, a sudden, horrifying silence descending upon the plaza, broken only by the rasp of Branka’s own breathing. The storm continued to churn, but its immediate, amplified assault had been paused. He took a step closer, his eyes, burning with a cold fanaticism, fixed on Branka’s face, on the terror and fury warring in her expression as she knelt beside Stoyan’s still form.
“A tragic but necessary sacrifice, Branka,” Ivanek’s voice, now calm and measured, sliced through the air. “But it doesn’t have to be permanent. Let the storm spread. Let the world be inoculated. And I will use my master-catalyst… to save his life.”
