Blood Oaths & Broken Wars

The war was going badly. Hope wore thin, worn down by funerals and betrayals. And Hermione Granger was tired of watching the people she loved die. So she turned to something older than wand magic. Something forbidden. Buried in the bowels of the Black Family Library, there it was: Vinculum Sanguinis. Blood magic-raw, binding, and irreversible. She wasn't summoning a spirit. She was summoning a soul. Regulus Arcturus Black: traitor to Voldemort, presumed dead, drowned by his own mission. The ritual was agony. It called for a drop of her blood, a binding vow, and a name spoken with intent. She gave more than a drop. When the circle of runes lit up with searing gold, and the air crackled like a storm breaking, Regulus appeared-naked, furious, and alive. "You called me," he said. His voice was low and sharp, like a blade drawn in the dark. Hermione collapsed, the toll of the ritual stealing her breath. "We're bound. Soul to soul. You're mine now." His eyes-those same steel-gray Black eyes-narrowed. "And you are mine." Regulus learned quickly. He was colder than Sirius, quieter. But once he understood what had become of the world-what Voldemort had turned into-he didn't hesitate. "We end this," he told her one night. "Not for the Order. Not for Potter. For family." He moved through the shadows. Undetected. Whispers of a third side rose. The war paused. Every living Black turned to him. Even the cursed ones. Even Draco. He didn't speak. He didn't need to. His presence said enough. They followed. He wasn't there for sides. He was there for blood. And anyone threatening Hermione Granger was already marked for death.
