Dispater wants to devour Lixer's knowledge and perhaps Lixer too, but he can't admit the latter one as he is the son of Asmodeus. Pretty much everyone apart from Caim, the Duke of Logic and Dispater's close servant, hates Lixer. However, Dispater knows that Lixer has nothing on him and is fairly confident that he would never try to cheat him. As a matter of fact, Dispater has tried to woo Lixer to his court on several occasions and Lixer considers his court the best place to be should he ever live Nessus.
