He has a pet wolf named Redmaw, is very skilled in the use of an enchanted axe, and dons Fur Armor. He has set up his camp on Gnoll Mountain, in the Jerall Mountain, southeast of Bruma, and he and his wolf will attack on sight. After progressing in the Dark Brotherhood questline, the Hero will find out that Havilstein is a Silencer in the Dark Brotherhood.
I have picked up my next contract from the dead drop in the hollowed-out tree stump. I have been ordered to go to the campsite on Gnoll Mountain and kill Havilstein Hoar-Blood, a savage Nord Barbarian skilled in the use of the axe.
