Oathbearer's Way

There's no time to rest, |n! While you were fightin' to secure those engines, a mob of greenskins found their way into Durak's Mine. There's plenty of bitterstone ore to be found in the mine, so them Orcs and Gobbos'll have to go! But what kind of Dwarfs are we if we don't take time to remember our ancestors? The Dwarf who found the very first vein in that mountain is entombed at the bottom of Durak's Mine. His name was Thronki Grimgirsson, and as ye might've guessed, he's my direct ancestor. Take this Rune of Preservation and hammer it into ol' Thronki's tomb. It'll keep the greenskin filth from desecrating his remains. Once you've tended to old Thronki, I'm going to need you to work a miracle down there. Like I said, the mine is old. It ain't holdin' up too well and the beams could buckle. You have to find a way to make sure the mine don't collapse!

Find Thronki Grimgirsson's Tomb at the bottom of Durak's Mine. Hammer the Rune of Preservation into it, and then speak with the awakened spirit of Thronki Grimgirsson.
