Kolkar Crag
From WoWWiki
The Kolkar centaurs have been plotting against the orcs ever since they arrived on Kalimdor. Though the Kolkar are mostly concentrated in the Barrens and areas farther to the west, a fringe group has taken up residence in a craggy gorge named Kolkar Crag, accessible from the southernmost shores of Durotar. Here, the Kolkar plot to launch an attack on the towns of Durotar: The Valley of Trials, Sen'jin Village, Razor Hill, and even the gates of Orgrimmar. The Kolkar here are lead by a mighty Centaur warlord dispatched from Desolace: Warlord Kolkanis.
