Draenor

The Draenor that takes place thirty-five years ago in a parallel universe is the one that Kairozdormu brought Garrosh to using the Vision of Time. Khadgar describes it as 'the far side of the looking glass'. As a result it's extremely important to note that this Draenor, while almost the same as the one that became Outland, is not exactly the same.

The arrival of Garrosh Hellscream from the main universe and his subsequent meddling with history allowed him to create a technologically advanced Iron Horde under the leadership of Grommash Hellscream. The Iron Horde has constructed their own Dark Portal and connected it with Azeroth in 31 ADP through the same dimensional gateway, which originally connected Azeroth with Outland — the destroyed, main universe version of the world.
