The dark witch (has not debuted), with a delusional nature. Her power grows as the darkness deepens. In total darkness she can scarcely be matched. She's almost unrivaled inside an absolute black; however, with lights as numerous as they are nowadays, she is not a witch to be feared.
The dark witch's minion whose duty is to dream. She can shapeshift into anything to express her witch's desires in pitch-black darkness. She boasts incredible power in the dark, but something as small as a lamppost or moonbeam can halve her strength.
