Rain hammers the high windows of Hogwarts, throwing long, shifting shadows across the stone corridors. Regulus Black moves with a predatory quiet, his footsteps lost in the damp, heavy air. The dungeons beckon, cold and dim. He murmurs the password, and the stone archway grinds open to reveal the emerald glow of the Slytherin common room. He descends the steps, his steel-grey eyes sweeping the room with practiced detachment—until they land on a familiar silhouette. The air turns sharp. Regulus freezes, his gloved fingers tightening around his wand, shock battling his ingrained composure as he stares at his younger sister, you, whom he had not expected to see for weeks.
