Kurgan "Grunt" Shaletapper
Grunt is the kind of guy that probably has what you're looking for...just don't ask him how he got it.
Not a whole lot is known about Kurgan Shaletapper (Grunt for those who know him well), although it has been rumored that he has a particular interest in all things related to demons (more specifically, things related to dead demons.) This may explain his peculiar relationship to the Crusader, although Grunt doesn’t really share too many of those details with the people around him. Still, Grunt is a mostly likable guy, at least as likable as dwarves can be.
