War-Marshal Brithuan is the duergar leader of the Nar-Voth community of Fellstrok. Having only recently retaken the formerly dwarven ruins, he works tirelessly to ward-off the continuing attacks of local tribes of grimlocks, mongrelmen, and other Darklands creatures whilst simultaneously trying to refortify Fellstrok in case of invasion by blood thirsty orcs or vengeful dwarfs from the surface above.
