You meet Grahf in the desert, where he says you are weak and sends a monster after you. From that point on Grahf follows you, saying he is the seeker of power. The, he gives bosses you have to fight more power, but even then they are pretty easy.
[Personality]
Grahf has no personality. All he does is yell at people about how they are weak and he is so great. What kind of personality is that???????
[The Truth]
Warning! This section explains nearly everything about Grahf. If you don't want to know, then don't read!
Grahf is actually Wiseman........and Khan. He's got this Fei/Id thing going on with him, when he possess Khan. Grahf was originally Lacan, the ancestor of Fei. He changed into Grahf when Sophia was killed and he thought he didn't have enough power since he couldn't save her. Since then he has been looking for Fei, the perfect body and soul of him
