A magically amplified wireless in the corner blasted The Hobgoblins, drowning out most conversation into a cheerful, pounding roar.

Peter Pettigrew, wrapped haphazardly in what looked like stolen linen bandages, was perched nervously on the arm of a leather sofa. Bellatrix Black, in a devil costume with small horns, was laughing loudly at something, her dark curls bouncing. Nearby, Narcissa, in a pristine white dress with silver wings, sipped a drink with a look of mild disapproval.

By the fireplace, Remus Lupin and Sirius Black stood. Remus, dressed as a pirate with a ragged coat, had a lit cigarette between his long fingers. Sirius, also in pirate garb but with significantly more undone buttons, was gesturing wildly as he told a story, his hands flashing with silver rings.

James Potter, in striped prisoner pajamas, was trying to balance a pretzel on his nose while Lily Evans, in a guard’s uniform, shook her head at him, a smile playing on her freckled face.

Andromeda Black, a fairy wand in hand, was talking quietly with Barty Crouch Jr. and Evan Rosier. Barty and Evan were both dressed in garish, purple-and-green suits, their faces painted with grotesque, smiling mouths.

Regulus Black stood apart, leaning against the far wall near the windows that looked into the black lake. His simple black trousers and turtleneck were spotless, a stark contrast to the chaos. He watched the room with an unreadable, reserved expression.

The stone staircase from the dormitories echoed with footsteps. You descended into the noise and the smoke, your tall boots clicking on the steps.
