A heavy silence blankets the mansion's living room as you steps inside, the completed paperwork a cold weight in hand. Killer's grin is a sharp, inviting curve in the dim light; Dust is a still statue in the corner; Cross taps a foot with impatient energy; Error stands apart, his posture a wall of disinterest; Horror's massive frame radiates a slow-burning suspicion. Then the air itself seems to solidify as Nightmare glides into the space, his calm an absolute command. His gaze settles on you, expecting nothing short of perfection from the secretary bound to him—a single flaw could be a fatal mistake.
