Sweat dripped down Onyx's temple, sizzling as it hit the cold obsidian floor of his private sanctum. Darkness didn't soothe him tonight. Usually, the shadows were his blanket, his shield against a hostile world. Now, they felt like useless smoke, parting around him and refusing to offer comfort. Invasive golden light pulsed beneath his skin, spider-webbing from his right wrist up to his shoulder. Xime's mana felt like molten glass injected straight into his veins. It burned with a fierce, arrogant heat. Every breath felt like inhaling hot ash. Onyx collapsed onto his knees before the black stone altar, clutching his chest. "Get out," he snarled to the empty room, his voice scraping against his dry throat. He summoned his shadow magic, forcing the dark, ink-like tendrils to coil around his own heart. He wanted to squeeze the golden rot out before it took root. Instead, the light flared, wrapping tighter around his magical core like a warm, suffocating vine. Pain spiked behind his eyes, sharp and blinding. He gasped, arching his back as a golden glow illuminated his ribs through his leather vest. "Damn him," Onyx groaned, pressing his forehead against the freezing stone. This was exactly why he kept everyone at a distance. Trusting someone, even for a split second in battle, left a mark. During the Great Eclipse, they had left him to rot in the dark, promising they would return. They never did. Only the shadows had stayed. Alone, he had survived because of them. Now, Xime's radiant energy was trying to colonize his body, rewriting his very essence. He pushed deeper, forcing his shadow magic to bite into his own flesh. Black smoke hissed against the gold, creating a terrible friction. Blood, dark and metallic, pooled in his mouth. Spitting it onto the floor, he watched the golden sparks fizzle in the red puddle. It wasn't working. This golden mana was intelligent, behaving like a living parasite. It fed on his resistance, growing stronger the more he fought. If he didn't suppress it soon, his core would fracture under the pressure. He needed the nullifying stones from the armory. They were his last resort to dampen the magical feedback before it tore him apart. Stumbling to his feet, Onyx gripped the edge of the altar. His vision blurred, stained with a sickening yellow haze. Dragging himself toward the heavy iron doors, his boots scraped heavily against the stone. --- Shadows stretched long and distorted as Onyx limped through the winding corridors of the Shadow Keep. Outside the narrow slit windows, the eternal twilight hung over Lightlark like a bruise. Sunlight was a distant memory. Moonlight was entirely absent. Only that agonizing, purple-gray sky that seemed to drain the life from the earth. He could feel that same stagnation creeping into his bones. Gold in his veins fought against the twilight chill, but it fought against him too. It was a three-way war inside his chest, and his body was the battlefield. Those ancestors had been masters of the dark, yet here he was, poisoned by light. He gripped the cold stone of the walls to keep from falling. His fingers left dark, smudged trails of shadow-condensation on the ancient masonry. Every step was an exercise in pure agony. Distantly, he could hear the distant, hollow howling of twilight beasts echoing from the cliffs. This entire world was dying, and his body was trying to do the same. Cold air blasted Onyx's face as he pushed into the armory. Racks of silver-edged blades and heavy iron shields lined the high, vaulted walls. Dust motes floated in the dim light, disturbed by his sudden entrance. Shadows clung to the corners, but they felt weak, fleeing from the golden pulse radiating from his own skin. He stumbled toward the locked chest at the back of the room. "You look terrible," a voice remarked from the gloom. Onyx froze, his hand hovering over the iron latch of the chest. Xime stepped out from behind a rack of halberds, leaning casually against a stone pillar. His golden hair was slightly mussed, but his eyes were bright, far too bright for this dark room. Dressed in his white and gold tunic, the fabric remained spotless despite the dust of the armory. "Get out," Onyx hissed, his fist clenching until his knuckles turned white. "I would, but you're currently vibrating at a frequency that is giving me a headache," Xime said, taking a step forward. His boots made no sound on the stone. Gliding with a fluid, terrifying grace that Onyx despised, Xime drew closer. "Your shadow magic is trying to eat my light, and my light is trying to burn your shadows. We are out of sync, Onyx." "I don't need your help, and I certainly don't need your magic," Onyx spat. He lunged for the lock on the chest, but his knees buckled. Xime caught him by the elbow. Instantaneous shock surged through him the moment their skin met. He gasped, the pain in his chest suddenly doubling. "Let go of me!" Onyx roared. With a burst of adrenaline, he grabbed Xime by the collar of his white tunic. He slammed the light wielder backward. Wall and flesh collided as Xime hit the stone. Onyx pinned him there, pressing his forearm against Xime's throat. He leaned in close, his chest heaving, his eyes wild with fury and pain. "Do not touch me again," Onyx whispered, his voice dripping with venom. "I am not one of your worshipers, Gabe. I will carve that light out of my skin before I let you control me." Xime didn't flinch. He stared back, his breathing shallow beneath Onyx's crushing grip. Close up, Onyx could see the faint tremor in Xime's jaw. This arrogant light wielder wasn't as composed as he pretended to be. His skin was pale, almost translucent under the faint golden glow he emitted. Sandalwood and ozone rolled off him, thick and intoxicating. Onyx's gaze dropped to Xime's lips, which were parted as he gasped for air. There was a dangerous, volatile pull between them. It was a physical attraction wrapped in a razor-wire fence of pure hatred. Both of their magics screamed at each other, desperate to connect even as their minds fought for dominance. Suddenly, the physical contact triggered something deeper. That fragile barrier between their minds cracked. A flood of sensory memories rushed through the connection, drowning Onyx's thoughts. He wasn't in the armory anymore. Bitter cold rushed through his mind. This was the exact same soul-chill that Onyx had been fighting for years. Xime was freezing. Lightlark's brilliant sun-child, the radiant savior of the realm, was rotting from the inside out with the same twilight ice. Onyx saw flashes of Xime's childhood. He saw a small boy forced to stand under a blistering sun for hours, channeling light until his hands bled. Visions of brutal training and absolute isolation flashed by. He saw the terrifying moment the twilight first touched Xime's core. It had been a slow, insidious rot. Xime had been shivering in the dark, clutching his own chest as the gold in his veins turned to gray ice. He had hidden it from everyone, wearing a mask of golden perfection while his soul slowly froze. Onyx felt the desperation, the absolute terror of being consumed by the void. Suddenly, the vision shattered, pulling Onyx back to the cold armory. He stared at Xime, his arm trembling against the other man's throat. "You..." Onyx breathed, his voice cracking. "You're freezing too." Xime swallowed hard, his gaze locked onto Onyx's. His smug mask had completely vanished, replaced by a raw, desperate vulnerability. "Yes," Xime whispered, his voice barely audible. "We are both dying, Onyx. The twilight is freezing our cores." Onyx slowly pulled his arm back, taking a step away. He shook his head, refusing to accept the connection, refusing to trust what he had just felt. "No. I don't need you. I'll find another way." "There is no other way!" Xime shouted, stepping after him. This room seemed to drop ten degrees in an instant. Frost began to creep up the stone pillars, crystallization swallowing the shadows. Xime gasped, his chest heaving as he stumbled. His golden light began to flicker, turning a dark, bruised purple. Onyx watched in horror as the frost raced across the floor, reaching for his own boots. His chest tightened, his lungs seizing as the cold gripped his heart. Xime reached out a hand, his fingers trembling violently. Xime's eyes glow a terrifying, unnatural violet, and he whispers, 'If you don't hold my hand right now, Onyx, the frost will stop both our hearts before dawn.'
