Dorthar

Dorthar is a centaur from Desolace that was nearly killed in the Southern Barrens by his own kind and Verdrak, whom he looked up to, for being known as a "runt". Dorthar was saved by the orc Malgar just before his execution. He then aided the Garad'kra, telling them about a new centaur leader named Aratas and an imprisoned group of orcs. While traveling to Desolace by a zeppelin, Dorthar underwent a series of tests with the Garad'kra. When the group arrived to Maraudon, Dorthar promised to free and accompany the prisoners to the safety while the rest of Garad'kra fought against Aratas and his "father". He eventually joined the Horde, the first known centaur ever to swear the Horde oath.
