Origin
Durotar
Thrall (birthname Go'el), son of Durotan (born the year 0 ADP), was the Warchief of the restored orcish Horde and ruler of the red land of Durotar in Kalimdor. Before the Cataclysm, he was Warchief of all the Horde, but temporarily gave leadership to Garrosh Hellscream in order to lead the Earthen Ring's effort with Farseer Nobundo against the Twilight's Hammer cult and elemental imbalance afflicting Azeroth caused by the awakening of Deathwing. After Garrosh's tyranny was overthrown, Thrall renounced his claim on the title of Warchief and instead gave the position to his close friend and ally, Vol'jin.
