The Dark Portal in the Blasted Lands has turned blood red. Hundreds of strange-looking orcs are violently pouring into Azeroth, killing everything that stands in their path. Nethergarde and Okril'lon have already fallen, and while the Horde and the Alliance moved as quickly as they could to get reinforcements to their people, they are too late. The Iron Horde invasion has begun.
In this desperate hour, King Wrynn and Warchief Vol'jin have called upon their greatest champions to join the front lines in the Blasted Lands and do whatever they can to stop the Iron Horde . . . before the rest of Azeroth falls before them.[2]
The world event will see a number of quests in a phased level-90 only version of the Blasted Lands, with the zone transformed by the invasion of the Iron Horde. For the full quest line, see Warlords of Draenor intro experience.
Upper Blackrock Spire[]
An advance party of Iron Horde forces has barged right out of the Blasted Lands and pushed all the way to Blackrock Mountain, where they found refuge and supplies in Upper Blackrock Spire. There can be only one response: the Alliance and the Horde of Azeroth must face this iron incursion head on.[2]
The subject of this section did not make it out of the beta stages.
Originally, the event featured much more enemies presented as rare mobs. Their diverse appearance hinted that they were followers of Garrosh from the True Horde and the Dragonmaw clan rather than coming from the alternate Draenor. Okrilla and part of her forces were also to betray the Horde for the Iron Horde.
Karazhan was initially planned to be visited in a scenario in order to investigate its link to the Dark Portal, but the idea was scrapped before the beta.[3]
