Months have passed since the cataclysmic Battle of Mount Hyjal, which put an end to the Burning Legion's invasion. Most Legion forces on Azeroth have been slain or driven into hiding. Yet now a mysterious energy rift in the mountains of Kalimdor propels three heroes to the distant past: the dragon mage Krasus, the human wizard Rhonin, and the weathered orc veteran Broxigar. It is a time long before orcs, humans, or even high elves roamed the world. A time that marks the Legion's first invasion of Azeroth, brought about by Queen Azshara and other night elf nobles. A time when the Dragon Aspects are at the height of their power -- unaware that one of their own will soon turn on the world he was charged to protect.
