Kapitel 1058: Delay Tactics.

He expects it to be difficult to seal the Ghouls and it should be nearly impossible to seal the particular one that chased after him. After all, Ragnarok is one of its targets and he is still alive. It will never rest as long as Ragnarok is still out there. But that is not enough to guarantee the spread of the blight. 

He intends to help the ghouls actively spread throughout the Underdark and the plane. And he won't let whatever the Vampires used to seal the Ghouls before work again. They will have him to contend with too if they want to seal the Ghouls. So he went around disrupting the Vampire's response to the ghouls.
