The scattered wastes of Outland are all that remain of Draenor, the once beautiful homeworld of the orcs. Following the Second War, the Alliance invaded Draenor by crossing through the Dark Portal. To their horror, they discovered that Ner'zhul - the dark warlord of Horde - had constructed a series of new gateways that could lead the beaten Horde to newer, unspoiled worlds. As the Alliance forces closed in around him, Ner'zhul opened his gateways as a means of escape. However, the gateways' clashing energies resulted in a catastrophic explosion that ultimately ripped the world of Draenor apart.
Nearly thirteen years later - towards the end of the Third War - the fallen night elf, Illidan, discovered that huge chunks of Draenor still existed - floating upon the astral winds of the Twisting Nether. After his defeat at the hands of the evil Prince Arthas, Illidan fled to the remnants of Draenor and dubbed them Outland. He quickly seized control of the chaotic region and sealed the last of Ner'zhul's cursed gateways.

Though he is the undisputed ruler of the ravaged land, Illidan lives in fear that he will be discovered by his powerful enemies - most notably Arthas, the new Lich King, and the remaining Lords of the Burning Legion. Currently, Outland is home to a number of scattered draenei tribes, primitive orcs and the powerful, arcane creatures of the Nether itself. Agents of the Burning Legion have also targeted the region as a vital strategic location in their unending Burning Crusade to scour all life from the universe.
