In the Age of Men’heva, Jaina Proudmoore is a skilled warrior and the leader of the rebellion against Men’heva’s Alliance. She is also the ruler of the disparate nation of Theramore, composed of outcasts and refugees from other nations.
Jaina rescued Warester Van Dam, Krasus, and Hocus Snood from the clutches of Rhonin and his Raptor Army, killing General Rhonin in the process. She accompanied the time travelers and a hand-picked elite infiltration team to covertly enter Karazhan and reach the Scroll of Lore.
At some point, the demon Estrogan took her place. Jaina's fate is unknown but her death seems likely.
