So... From the above I get that the PC's will have little understanding of what's going on or what this enemy is all about. It sounds like none of them got much chance to figure any of it out before trying and failing to oppose him. But as a potential player I have to know. Does this Kazzok have an actual motivation behind his actions or is he just some 2 dimensional "I  do it for the evulz!" kind of antagonist?
