The night reeked of blood. High above the burning forest, the Vampire King stood motionless, his crimson eyes reflecting the flames. For centuries, he had ruled with an iron hand, a monster cloaked in shadows, cursed to feel nothing—not sorrow, not joy, not even love. His kingdom feared him, his enemies hunted him, but none could wound him as deeply as the silence in his own chest. A thousand years ago, a witch had sealed his fate with a prophecy: “When the King’s heart beats again, his reign will end. His mate will either save him… or destroy him.” He had laughed then, arrogant and cruel. But now, as the screams of dying rogues echoed through the night, something inside him shifted. A single heartbeat. A pulse that wasn’t his own—but hers. Through the smoke, he saw her. A girl, human yet not, blood running down her arm, her terrified eyes locking with his. She should have been prey. She should have been nothing. But the curse stirred, breaking its chains with a force that rattled his bones. The King’s chest burned. For the first time in centuries, his heart beat. Once. Twice. He staggered back, his hand clutching the fabric over his chest, unable to tear his gaze away from the trembling girl below. “She’s the one,” he whispered, voice breaking like glass. The prophecy had come alive. And with it, the promise of his downfall.
