Slay Hezrul Bloodmark and collect his head.
Hezrul Bloodmark is the leader of the Kolkar centaurs in the Barrens. He is fierce, brutal and cunning. Defeating him would disrupt and fracture the Kolkars, greatly reducing their threat to us.
So kill him. Bring me Hezrul's Head, and I will mount it from this outpost, so that they may know fear.
Hezrul leads his people from the Lushwater Oasis, to the south.
