Warcraft Lore: Archimonde Destroys Dalaran
As Thrall continues to rally the Horde and Tauren in Kalimdor, Arthas and Kel'Thuzad summon Archimonde to Lordearon.
This powerful demon is an Overlord of the Burning Legion and uses his powerful magic to destroy Dalaran, city of the Kirin Tor. This is a step closer for the undead Scourge and Burning Legion to conquer all of Azeroth.
