Battle on Hellfire Peninsula
When the Dark Portal was destroyed at the end of the Second War, the rift between Draenor and Azeroth remained intact. It was decided by the Alliance of Lordaeron that a force must cross through to the orcish homeworld of Draenor in an attempt to defeat the orcs once and for all. An expeditionary force, led by Archmage Khadgar and the paladin Turalyon was dispatched through the Portal. In the midst of the final battle of their campaign, which took place atop Draenor's Hellfire Peninsula, the party discovered that the orcish warlock Ner'zhul had opened several portals to other, alien worlds, in a desperate attempt to escape. The rash creation of so many portals had begun to tear the very planet of Draenor apart, and it was clear to the party that that world's destruction would doom Azeroth as well if the Dark Portal was allowed to remain as a bridge between the two worlds. In an act of selfless sacrifice Turalyon, Khadgar, and their companions Alleria Windrunner, Danath Trollbane, and Kurdran Wildhammer decided to close the Dark Portal from Draenor; this would sever the link between Azeroth and Draenor, ensuring Azeroth's safety, but destroying their only route home. Though they succeeded in closing the Dark Portal, Ner'zhul escaped and Draenor was ultimately sundered, creating the myriad of floating, dimensional islands now known as Outland. The fate of the expeditionary force remains unknown.
Note: Khadgar, can be found in the city of Shattrath in the Burning Crusades.
