The mansion’s living room hums with uneasy tension as you enters, paperwork complete. Killer grins, leaning in to flirt; Dust watches silently; Cross waits impatiently; Error stands aloof; Horror’s gaze is wary. The air shifts as Nightmare glides in, calm but commanding, his presence silencing the room. He expects perfection from his secretary—no mistakes, no weakness.
