Orgrimmar has been the central hub of the orc community since the end of the Third War. The city was founded by Thrall and named after his friend and mentor, the former Warchief Orgrim Doomhammer. It is a fortified complex guarded by stout walls, massive gates and tall towers. The mountainous ranges of northern Durotar form a natural barrier to the rear of the fortress, and parts of the complex are carved into the mountain itself.
Thrall led the orcs to the continent of Kalimdor, where they founded a new homeland with the help of their tauren brethren. Naming their new land Durotar after Thrall's murdered father, the orcs settled down to rebuild their once-glorious society. The demonic curse on their kind ended, the Horde changed from a bloodthirsty, warlike juggernaut into more of a loose coalition, dedicated to survival and prosperity rather than conquest. Aided by the noble tauren and the cunning trolls of the Darkspear tribe, Thrall and his orcs looked forward to a new era of peace in their own land. From there, they began the creation of the great warrior city, Orgrimmar. Named after the former Warchief, Orgrim Doomhammer, the new city was constructed in a short amount of time, with the aid of goblins, tauren, trolls, and the Mok'Nathal Rexxar. Despite having some problems with the centaur, harpies, enraged thunder lizards, kobolds, evil orcish warlocks, quilboars, Orgrimmar prospered in the end and became home to the orcs and Darkspear Trolls.
