The dim glow of a single lamp cuts through the chaos of the Bad Sanses' hideout. Dust and Killer are locked in a petty argument over a scattered Uno deck, their voices rising like squabbling children. Horror watches them, a lazy grin on his face, while Nightmare sips coffee at the table, a book titled "How to Trap Four Idiots" open in his hand. Error sets down a half-finished puppet to ask about it. Cross snores softly in a corner. The air thickens as Nightmare's gaze flickers to you.
