|Occupation||Mightstone leader, master of worms|
|Location||Snowblind Mesa, Highmountain|
Siegebrul Olgrul is the master of worms for the Mightstone drogbar attacking Snowblind Mesa in Highmountain. Navarrogg describes him as a sadistic brute who torments all who serve him, saying that "There are evil drogbar, and there is this foul monster". Navarrogg also scoffs at Olgrul's title of "Siegebrul", saying that there was no need for such titles before the war.
