Cold sweat dripped down Onyx's spine, freezing the moment it touched his leather collar. Frost crusted over the cobblestones beneath his boots, a stark reminder of the twilight rot creeping through the ruins of the ancient sun temple. "Get up," Xime grunted, his voice stripped of its usual mocking warmth, raw with exhaustion. Onyx didn't answer, his knuckles turning white as he gripped the crumbling stone wall to steady his shaking legs. Looking down at his feet, he felt his stomach drop into a cold, bottomless void. Nothing stretched behind him under the dim twilight, no dark shape mimicking his form. Dark, viscous liquid seemed to seep from the edges of his boots instead of a natural reflection of light. It rose from the stone, stretching upward, taking on a terrifyingly familiar silhouette. Two eyes burned from the center of its featureless head, twin embers of corrupted purple that mirrored his own magic. Onyx felt his breath catch in his throat as the entity fully detached itself from his body, standing tall and imposing. "Stay back," Onyx hissed, his fist clenching as he tried to call upon his shadow threads to crush the intruder. A sharp, agonizing pain ripped through his sternum, stopping him mid-breath. Black veins pulsed along his forearm, but his magic refused to obey his command, twisting violently. He choked on a gasp, dropping to one knee as the dark power turned back on him, searing his veins like liquid fire. Swiftly, his own detached shadow lunged forward, claws of solid darkness aiming directly for his throat. From the misty borders of the clearing, low growls echoed from the encroaching twilight beasts. Twilight beasts were circling, drawn by the scent of spilled magic and vulnerable prey. Xime stepped forward, his body practically radiating a bright, golden aura that pushed back the immediate chill. "Catch!" Xime yelled, tossing a weapon through the dim air. Something bright flashed in a tight, gleaming arc. Onyx caught the weapon by instinct, his palm burning as his fingers wrapped around the hilt. Light and shadow twined around the silver blade of the dagger, humming with a strange, stabilizing energy. "It's dual-infused," Xime shouted, drawing his broadsword to keep the twilight beasts at bay. "Your magic is turning inward. Use the blade to sever the connection!" Heavy footsteps thudded behind Onyx as his shadow circled him with predator speed, mimicking his exact combat stance. Gritting his teeth, Onyx spun, raising the silver dagger just in time to block a strike from his own shadow. Pain flared through his chest, a direct mirror of the impact on the blade, making him gasp. Every strike he made against his own shadow felt like a physical tear in his own soul. "Don't fight it alone," Xime's voice rasped close to his ear, heavy with exertion. Before Onyx could protest, a heavy warmth pressed against his back. Heat flooded his freezing limbs as Xime stepped into his space, chest pressing against Onyx's shoulder blades. Xime's left hand slid down Onyx's arm, gripping his wrist to steady the shaking blade. Together, they braced against the shadow's relentless onslaught, their movements perfectly aligned. "Left," Xime whispered, his breath hot against Onyx's neck, sending shivers down his spine. Onyx lunged left, guided by the firm pressure of Xime's body against his. Shadows from the surrounding trees whipped toward them, but Xime's radiant magic flared, burning them to ash. Golden light pulsed from Xime's skin, sinking into Onyx's pores and stabilizing the chaotic, freezing dark within him. Their bodies moved in a desperate, seamless motion, pressing together to maintain the elemental flow. Onyx could feel the hard lines of Xime's chest, the rapid beat of his heart matching his own. Every movement required absolute synchronization to keep the dark magic from consuming Onyx. Without Xime's physical touch, the dark magic in Onyx's veins would expand and crush his heart. Pressing closer, Xime guided Onyx's hand upward, aligning the dual-infused dagger with the shadow's chest. "Now!" Xime roared, his grip tightening on Onyx's wrist. Driven by sheer survival instinct, Onyx thrust the dagger forward, burying the silver blade deep into his shadow's chest. Vile, dark fluid erupted from the wound, dissolving into gray mist. A silent scream echoed in Onyx's head, a phantom agony that made him drop to his knees, gasping for air. Onyx fell backward, his head resting against Xime's sturdy shoulder as his vision blurred. Looking up, he watched the remaining fragments of his shadow twist and warp in the fading light. Whispering with a chilling, hollow resonance, the detached shadow stared at Onyx with its fading purple eyes. "He will abandon you too, once the sun burns out."
