“Detonate?!” Bollan roared, snapping his attention from the sputtering Magistrate. He lunged for Kavvi, but the guards, still loyal to Fennik, held him back, their spears forming a cage. "Get back!" one of them barked, his voice tight with fear. The band on Kavvi’s arm throbbed, a malignant pulse of cold rot warring with searing heat. Her vision blurred at the edges, the vibrant colors of the forge receding into a gray haze. The burn on her forearm deepened, a raw, angry wound that began to weep black ichor. It smelled like scorched copper and dying magic. Pippit, a blur of six legs, zipped from Kavvi’s shoulder, a furious orange streak. He launched himself at the iron cuff, tiny fangs scraping uselessly against the tightening metal, a growl rattling in his chest like loose pebbles. “The forge is going to blow!” Vorl shrieked, scrambling away, abandoning his overturned chair. “The full mana-engine is in here! It’ll level the entire tier!” Fennik ignored him. His gaze was fixed on Kavvi’s arm, his face stark white. He grabbed her wrist, his fingers trembling as he felt the fierce, draining current. “It’s absorbing your life force! It’s fueling its own destruction!” He slammed his free hand onto the override panel on the wall, hammering at the controls. “The key isn’t working! Lirra’s inverted filament has jammed the entire release sequence!” The air around Kavvi shimmered, the light dimming as if the very essence of the room was being sucked into the collar on her arm. Dust motes danced in the strange, failing illumination, caught in miniature chaotic eddies. She felt a profound weariness settle into her bones, heavy and damp, pulling her down. A dizzying nausea churned in her gut. “No, you don’t, you rusty piece of junk!” Kavvi croaked, her voice weak but still laced with a defiant tremor. She forced a grin. “Can’t go blowing up the forge! Think of the property damage! And honestly, a girl needs her arm for… strategic marital advances.” Fennik didn’t smile back. His eyes, usually clouded with worry or focused on some impossible calculation, were now a fierce, burning amber. He glanced wildly around the expansive forge, his gaze settling on the mana-engine, humming with subdued power in the center of the room. A frantic calculation sparked behind his gaze. “The engine,” he breathed, his voice a low, urgent hum. “The Lumin-Core converter can absorb the feedback. It can channel the reverse charge.” Alarm stabbed through Kavvi, sharper than the pain in her arm. “Fennik, no!” She tried to pull her wrist free. “That thing is meant to *power* a city, not eat a death sentence! You’ll be disintegrated!” He held her fast, his grip surprisingly strong. “It’s the only way to break the inverted circuit without blowing us all to the Sunless Pit. The conversion will shatter the iron.” “And you?!” Her voice cracked, a genuine, raw fear finally pushing past her practiced humor. “What about you, you brilliant idiot? You’ll be fried faster than a desert beetle on a sunstone!” Tears welled, hot and stinging, blurring her view of his desperate face. She pushed against his chest with her good hand, trying to create distance. “Don’t you dare! What good is a billionaire husband if he’s a pile of ash? I’ll find another way! I’ll just… cut it off!” She fumbled for a discarded blade near the workbench, her fingers clumsy and numb. But Fennik caught her hand, holding it tight, pulling her closer instead of letting her go. His gaze locked with hers, sharp and unwavering. “Kavvi.” His voice was rough, unyielding. “I refuse to let you go. Not now. Not ever.” His thumb brushed over her knuckles, a feather-light touch amidst the chaos. “You brought me back from the edge. You gave me a reason to *live*. You are my reason.” His words, delivered with such fierce, uncharacteristic conviction, hit her harder than any blow. Her resistance drained away, leaving her suspended in a brittle clarity. He truly meant it. Bollan, finally breaking free from the guards, saw the connection Fennik was making, saw the grim panic etched across his features. “Fennik, wait! There has to be another way!” “There isn’t!” Fennik yelled, his gaze unwavering from Kavvi. He reached for a control panel integrated into the mana-engine’s core housing. With his free hand, still clutching Kavvi’s wrist, he activated a direct conduit. A thick, metallic cable snaked out, glowing with contained current, and Fennik, without hesitation, pressed its terminal against the sparking collar on Kavvi’s arm. A blinding flash of raw luminescence erupted. The air crackled, reeking of scorched copper and ozone. The mana-engine roared, a deep, resonating hum that vibrated through the floor and up Kavvi’s legs. Its Lumin-Core, usually a soft, steady thrum of light, pulsed violently, absorbing the lethal feedback from the cursed collar. The glow intensified, turning from gold to a searing, almost painful white. Kavvi cried out, not from pain, but from the sudden, overwhelming sensation of life flooding back into her, pushing out the cold rot. The collar on her wrist vibrated furiously, the inverted filament screaming as it was torn apart by the opposing currents. Sparks flew, not crimson this time, but pure, blinding white. The metal band glowed incandescently, heating to an impossible temperature. Then, with a deafening *CRACK!*, the band shattered. Fragments of superheated metal exploded outwards, dissipating into motes of pure light before they could even hit the ground. Kavvi’s arm, though scorched and raw, was free. But the force of the release, the violent mana conversion, ripped through Fennik. His body stiffened, a silent scream caught in his throat. His gaze, still locked on Kavvi’s, lost focus before his eyelids fluttered shut. His grip on her wrist went slack, his hand falling away like a forgotten leaf. The last of the brilliant Lumin-charge pulsed through the apparatus, then dimmed, leaving the forge bathed in a softer, golden glow. Fennik Mokkan, the brilliant, broken scholar, collapsed to the flagstones. He lay utterly still, his chest unmoving, his face peaceful in the golden light. Kavvi fell to her knees beside him, her free hand reaching out, trembling as it hovered over his pale, still face. “Fennik?” she whispered, her voice a ragged, broken sound. She shook his limp shoulder, her vision blurring with fresh tears. “Fennik, wake up! You… you can’t die now. We just got started! You… you promised we’d beat this together!”
