Ner'zhul finally opened his portals to other worlds, but he did not foresee the terrible price he would pay. The portals' tremendous energies began to tear the very fabric of Draenor apart. As Turalyon's forces fought desperately to return home to Azeroth, the world of Draenor began to buckle in upon itself. Grom Hellscream and Kilrogg Deadeye, realizing that Ner'zhul's mad plans would doom their entire race, rallied the remaining orcs and escaped back to the relative safety of Azeroth.

On Draenor, Turalyon and Khadgar agreed to make the ultimate sacrifice by destroying the Dark Portal from their side. Though it would cost their lives, and the lives of their companions, they knew that it was the only way to ensure Azeroth's survival. Even as Hellscream and Deadeye hacked their way through the human ranks in a desperate bid for freedom, the Dark Portal exploded behind them. For them, and the remaining orcs on Azeroth, there would be no going back.

Ner'zhul and his loyal Shadowmoon clan passed through the largest of the newly created portals, as massive volcanic eruptions began to break Draenor's continents apart. The burning seas rose up and roiled the shattered landscape as the tortured world was finally consumed in a massive, apocalyptic explosion.
