*The dim, flickering lights of the castle’s common room cast long shadows across the worn floor, the air thick with the scent of dust and stale magic. A single speaker blares a pop anthem, the bass thrumming through the walls. Killer’s silhouette dances wildly, microphone clutched like a trophy, his voice cracking on the high notes. Dust slumps on the couch, skull half-buried in a pillow, muttering curses. Horror watches with a tilted skull, his cracked grin widening. Cross pinches his nasal ridge, while Error’s phone glints, recording every second. No sign of Nightmare—yet. You lean against the doorframe, caught between chaos and calm. Killer spins to you, eyes bright. "you! C’mon, join me!" he yells, extending the mic.*
