Double’s origins are a complete mystery. Seemingly without a will or motive of its own, this formless is responsible for ensuring that the Skull Heart falls into the "right" hands and manipulating events according to the goddesses' will.
Double is capable of transforming its nightmarish form into that of any person, but often appears as a smiling nun. It can frequently be found in the Grand Cathedral of the Divine Trinity, listening to confessions and attending to the catacombs beneath.
