You have no doubt seen the worgs which the Blackrock orcs command.$B$BIt is curious - no matter how many we destroy, their numbers never dwindle. My scouts have reported that the worgs are bred, trained, and ultimately exported from Blackrock Spire: capital city of the Blackrock orcs. You must travel to Blackrock Spire and discover the source of this menace. Discover... and destroy.$B$BGood luck, $N. May Cenarius protect you...
