Using a magical cloak of darkness to escape the detection of the mages at Nethergarde, the Bleeding Hollow clan used the rift to return to Draenor. Hearing the Bleeding Hollow's tales of Azeroth, the Elder Shaman Ner'zhul, Chieftain of the Shadowmoon Clan and Warchief of Draenor, planned to open a number of portals on Draenor that would lead the Horde to new worlds to conquer. To do so, Ner'zhul required mystical artifacts - the Book of Medivh, the Skull of Gul'dan, the Jeweled Scepter of Sargeras, and the Eye of Dalaran. In order to procure these artifacts, the elder shaman reopened the Dark Portal and sent his forces through. King Terenas of Lordaeron, convinced that the orcs were preparing a new invasion of Azeroth, assembled his most trusted lieutenants, including Khadgar and the paladin Turalyon, to form an expedition through the Portal to put an end to the orcish threat once and for all.

Ner'zhul finally wow gold opened his portals to other worlds, but he did not foresee the terrible price he would pay. The portals' tremendous energies tore Draenor apart. Grom Hellscream and Kilrogg Deadeye - who saw that Ner'zhul's portals would destroy their world, and his insanity would destroy their people - led their clans through the Dark Portal back to Azeroth. The Alliance forces remained on Draenor, agreeing to make the ultimate sacrifice by destroying the Dark Portal from their side in order to prevent that world's destruction from destroying Azeroth as well. There are indications they may have taken one of Ner'zhul's portals to another world. They may also have survived Draenor's destruction, and remain in the shattered realm now called Outland.
