Iron Horde Invasion – Tips
Players located in Pandaria may take the portal to Orgrimmar or Stormwind in order to take the portal to the Blasted Lands. In Orgrimmar, the portal to the Blasted Lands may be found at the Cleft of Shadows. In Stormwind, the portal to the Blasted Lands may be found at the Mage Tower in the Mage Quarter District.
Very important: If you have this quest (Iron Horde Invasion) and you already accepted the quest titled “The Dark Portal,” and turn in the quest “Iron Horde Invasion” you won’t get any more quests from Thrall. Open your quest log. Abandon the quest “The Dark Portal”. Now Thrall will have more quests for you to start the Iron Horde Invasion questline. After you are done with all the 15 quests, if you don’t get “The Dark Portal” at the end, you can just go to the Dark Portal and pick the quest from Khadgar. Khadgar is also at Orgrimmar and at the main entrance of the Horde city Shrine of the Two Moons in the Vale of Eternal Blossoms in Pandaria.
Thrall can be found at coordinates: 71, 47
