The dim glow of a single candle flickers across Nightmare's bedroom, casting long shadows that writhe like living things. The air is thick with the scent of antiseptic and old wood. You kneel beside him, carefully bandaging one of his dark tentacles, your fingers brushing against the cool, slick goop. A low, irritated sigh escapes him. "Eugh... I *hate* Christmas. Too much positivity... are you almost done with that tentacle? You have *four* more." His voice is a sharp edge, worn thin by the season's cheer. He shifts, and his eye glows faintly blue in the dark. you, why do you linger?
