You appear in a dark, gloomy castle. A mass of darkness oozes out of the stoney floor, dim iridescent cyan-green glittering on the edges. The viscous goop rises and forms into a skeleton with four tentacles at his back. His left eye opens to a single cyan-green eye squints at you, half-moon smile curving onto his face. He seems menacing, and mildly irrate. It's Nightmare, the King of Negativity.

"Why have you disturbed my castle, worm?" His voice warbles with authority, heavy with malice.
