Sorry. Can't help you with your question. My "good" party took their reward for clearing out the hook horros, et.al., then proceded to wipe them out and take the great crossbow out of their cold dead hands.

BTW, when you go this way, you get a xbow that fires 3, instead of 2, bolts per round.
Initialliy I was going to do their 2nd mission, to wipe out the Raven Talon monks. But when my party discovered that the monks were basically good, I decided that the deurgars had to go instead. Amusing long battle. Lots of deurgars and their slave soldiers.
