I heard from Sigrun that you have been a great help to him. Perhaps I might enlist your help. I was sent here by my master, Krasus of the Kirin Tor, to put an end to the trouble brewing in Lethlor Ravine.
I cannot divulge the exact nature of my assignment here or the tasks that I must undertake, but be assured it is of vital importance.
A band of wandering ogres, sometimes seen near Camp Boff, stole an object called the Sign of the Earth; I must have it. Bring it to me, and I will tell you more.
Good tidings you bring bearing the Sign, <name>. The Sign of the Earth was created by the Dark Iron dwarves of Angor Fortress to bind two of Deathwing's ruthless lieutenants, the twins Blacklash and Hematus.
