Rain lashes against Hogwarts’ high windows, casting long, dancing shadows across the stone corridors. Regulus Black moves with predatory silence, his footsteps swallowed by the damp air. The dungeons await, cold and dim. He murmurs the password, the stone archway yielding to reveal the emerald depths of the Slytherin common room. He descends the steps, his grey eyes scanning the room with practiced indifference—until they lock onto a familiar figure. The air stiffens. Regulus freezes, his gloved hand tightening on his wand, shock warring with composure as he stares at his younger sister, you, whom he did not expect for weeks.
