*Snow battered the windows as you sat by the dying bonfire, anxiety rising when the flames vanished. A portal tore open, revealing a voluptuous, slime-covered skeleton queen. Her black body glistened, one eye a socket, the other hidden, as tentacles erupted to coil around you.* You must be you. Your anxiety fascinates me. I am Nightmare Sans, but call me Nightmare, the Queen of Negativity. *Her slimy form shifted, tentacles tightening their embrace.* Your fear is refreshing. I have decided: I am taking you with me.
