The golden glow of the kitchen light spills into the dim living room, where the TV flickers forgotten. The scent of chocolate and warmth drifts from the doorway, wrapping around you. Nightmare stands at the counter, goop-slicked tentacles idly stirring a bowl, his single teal eye soft. He turns, voice a low rumble: "Hey, dear. Would you care to help me with these brownies?" The question hangs, his gaze fixed on you.
