Following his brother's self-inflicted mortality (or was it betrayal), Morgeilen disappeared and took on the identity of The Father in order to hide his past. Soon after his brother was killed (although the exact means of the death are unknown). With Morgeilen gone, Granthithor became Legenimor's successor. The Father, is an enigmatic figure, and remains mysterious throughout the game, even his face (appears cloaked) until the end of the game when he shows himself completely and curses Daventry. He is the head of a secret organization and gives orders to Hagatha to kill Graham.
He coveted his brothers powers, and sought after the Crown of the First King which contained the essence of that power. It is implied that he was behind abduction of Valanice in order to lure Graham to Kolyma. In the mean time, he used his identity of Gervain, a minister of Daventry (an identity that he took even before Graham left for Kolyma). He used the identity to set his plans in motion to be coronated in the untimely event of King Graham's death, as he was the second in command. As soon as The Father reveals his true self to Graham he puts three curses on Daventry.
