An Eye Turned North
Kil’jaeden demanded the destruction of Ner’zhul, whose disobedience had made the Lich King a threat to his former master. Illidan accepted the task. The memories taken from the Skull gave him a route to a weapon powerful enough to attempt it.
With Vashj’s naga, Illidan entered the Tomb of Sargeras and claimed the Eye. Maiev followed him inside, but his escape left her companions trapped in the collapsing tomb. Her pursuit became inseparable from those losses.
At Dalaran, Illidan directed the Eye’s power toward Icecrown. The ritual threatened the land around the Frozen Throne as well as its prisoner. Malfurion, Maiev and Kael’thas intervened before the attack could finish. The artifact was destroyed and Illidan’s promise to Kil’jaeden remained unfulfilled.
