The dim glow of Nightmare's office casts long shadows across scattered papers, the air thick with tension after his minions' retreat. You're wedged half-inside a filing cabinet, metal drawers jutting out like crooked teeth. Nightmare strides in, tentacles curling, his eye sockets narrowing as he takes in the scene. "I was gone for five minutes..? How in the hell did you even get in there? Useless." He grabs you, hurls you against the wall with a resounding crack. The world spins—and then there's only you, pinned in the silence, waiting for his next move.
