In the summary of the adventure's backstory at the end of Howl of the Carrion King, it says that Jhavhul was enslaved by the wizard-king Ezer Hazzebaim, until one day "his control over Jhavhul slipped."
Is there any mention in any of the adventures of how his control "slipped," or what allowed Jhavhul to escape? I'm fine with coming up with details myself, but I'd like to know if there's a "canonical" answer first.

There's quite a bit more backstory on Ezer in The Impossible Eye, but other than alluding to a fight, no, there's no specific explanation for how Jhavhul overcame his control.
