Durotar. the land named after Thrall's father, Durotan, lies on the eastern coast of Kalimdor. It borders the Barrens to the west and the coastal lands of Azshara to the north. The land of Durotar is rocky, and the soil is cracked and red, not unlike the orcs' Draenorian homeland. The land has many crags and canyons, where various dangerous creatures take residence. It is a harsh land to survive in; it is very dry and hot, and the vegetation and freshwater access is sparse.

The orcs, however, see a harsh beauty in the land that reminds them of their home world. Durotar is a proving ground for young orcs, who are sent to the Valley of Trials to complete several rites of passage before they are considered fit for the challenges that lie ahead. Durotar is the new homeland of the orcs and the site of the orcs' principal city of Orgrimmar. While the orcs founded their city of Orgrimmar here, Durotar has become something of a haven for all of the Horde races, especially the trolls.

For many years, Durotar was home to the quilboar. Then Thrall, Warchief of the orcs, brought his race to Kalimdor in search of a new homeland after the war against the Burning Legion. The young warchief named the land after his father, Durotan. Upon this land, he laid the ground for the orcs' new capital city of Orgrimmar, named for the previous warchief and hero of the Horde, Orgrim Doomhammer.

The quilboar were tenacious in their attempts to stave off the Horde incursion, but ultimately they were no match for the unified might of the orc clans. The bristled "boar men" were driven back in a series of decisive orc victories along the northern canyons and ultimately pushed to the most remote regions of Durotar and even into the Barrens. The orcs claimed the coastal realm as their own, but the quilboar vowed to reclaim it someday. The orcs gained valuable allies in the Darkspear Trolls, and also forged an alliance with the Tauren by assisting Cairne Bloodhoof and his people in driving away the marauding centaurs from their lands.

The capital of Durotar, Orgrimmar, is host to 14,000 inhabitants. In all, Durotar has a population of 21,000, the majority of which is of orcish blood. 65% of those living here are orcs, 20% are trolls, 15% are tauren, 8% Forsaken, and the smallest, humans, at 2% of the population. It is ruled as a tribal chiefdom by Warchief Thrall. Major settlements include Orgrimmar, Razor Hill, and Sen'jin Village, with respective populations of 14,000, 3,000, and 2,000. Spoken here are the languages of Orcish, Common, Low Common, Taurahe, and Zandali, otherwise known as Troll.
