Dark Portal (alternate universe)
- For the Dark Portal from the main universe, see Dark Portal.
The Dark Portal is a gateway between the alternate-universe Draenor and the main-universe Azeroth. Its name comes from the main-universe Draenor's Dark Portal. It was used by the Iron Horde led by Grommash Hellscream and Garrosh Hellscream to conquer the world Garrosh had escaped from. The power source for the portal were the captured Gul'dan (who very likely had wanted to use it for invading different world), Teron'gor and Cho'gall.
After the Ironmarch invasion force was pushed from Azeroth's Blasted Lands, Archmage Khadgar led the united Horde and Alliance vanguard in the counter attack, eventually freeing the three warlocks, disabling the portal and crashing down the structure with the Iron Worldbreaker.
According to Magril the Seer the area still contained a portion of its power. This probably led to the opening of another portal in front of the Dark Portal's ruined stairs - the Black Gate - from which Archimonde arrived. At the site of the two portals Khadgar, heroes of Azeroth and Draenor attacked and defeated the demon lord.
- Before deciding to include the Dark Portal in alternate Draenor, the Altar of Flames was concepted to be in its place.
Kairoz mentioned that the two timelines were linked by his shard of the . While not directly specified to be the case, it is very likely that Garrosh used the shard to link the Dark Portal in the alternate universe to that of the main one in order to invade Azeroth.
