Father

The Father is an enigmatic figure, that seems to be after Graham's crown and becomes his archnemesis.

Nothing is known about the Father, not even his face (appears cloaked), nor his nature (can be a Human, or some kind of spirit). He seems to be the head of some secret brotherhood and gives orders to Hagatha in order to capture Graham. It's possible that he was after the abduction of Valanice in order to lure Graham in Kolyma. In the mean time, he takes the place of Gervain, the Prime Minister of Daventry.

We don't know what the title 'Father' refers to. He is probably the head of the sisterhood (perhaps the head of the Black Cloak Society), or the very creator of the witches that follow him.
