This is how things are playing out with Spetyco. There is an evil conjurer, who's history we've yet to uncover, who is after the book. Spetyco is somehow linked with this conjurer, again yet to be revealed, and he discovered this conjurer's plan to steal it. In order to protect it he steals it himself. It seems that Spetyco is the only one who can wield the power of the book, and since he will not bow to this conjurer, the evil one's plan is thus to take over Spetyco's body. He needs time to prepare to do this, so he first steals Spetyco's memory to put him out of comission before he takes over his body. He doesn't know Spetyco has already stolen the book, so he conjures a pack of ulbers to retrieve the book. Then we all run into the ulbers, and so on...
