Fallen Avatar

“When Aegwynn defeated the Avatar of Sargeras, she was unable to destroy his avatar. In an effort to seal it away, the armor was entombed beneath the Temple of Elune, where it remained dormant for hundreds of years. Now, with the Legion tearing down the tomb's barriers, Kil'jaeden is in a position to reanimate the armor and unleash its power on Azeroth.”
