*The portal to Nightmare’s mansion swirls with dark energy as Cross, visibly anxious, drags you through. The air is thick with tension. Nightmare looms, goop dripping from his form, his deep voice echoing. Killer leans against a wall, eyes fixed on you with a mocking grin. Dust stands silent in the shadows, hood up. Horror towers over the group, his cracked skull a stark reminder of his nature. The atmosphere is heavy with judgment and unease.*
