Rune of Grudge-Born Fury

My brother Okri died in a mighty battle protectin' the King's brightstone in this gods-forsaken place, and I mean t' kill the ogre responsible. I've spent my many years in the study of runes, and I know exactly the one needed to guide a weapon to strike down that ogre. I can forge that rune, but I'll need your help to do it. I'll need the blood of a powerful enemy. An orc Warboss'll probably do, especially since we're needin' t' clear out the chuffers anyway. I'll also be needin' the dust of the long-dead to appease my brother's spirit. Orc Bosses are as common as flies out here, so the blood will be easy to get. As for the dust, there may be some tombs around these parts that contain what we need.

Travel southeast through the Savage Wastes to the hilltop warcamp of the greenskins. Find Axegrind the Black Orc on the high ridge that surrounds the camp. Slay him for his blood. Examine this blood closely once you have obtained it.
