Sally Whitemane was the High Inquisitor of the Scarlet Crusade and a major villain in the Warcraft franchise. Several years after her death, she was risen in undeath as a Knight of The Ebon Blade, and in doing so, was freed of the insanity that plagued her in life.
Whitemane was raised by her parents in Lordaeron and played with her friends in Hillsbrad Foothills. Unfortunately, the undead plague swooped through Lordaeron and Sally witnessed her family contaminated by the plague, so she had no choice but to kill her parents and siblings. Years later, she joined the Scarlet Crusade in their quest to destroy the undead across Azeroth.
Eventually, the Crusade became more fanatical and sought to destroy anyone that was not with them after Renault betrayed his father. Sally became the high priestess of the Scarlet Monastery with Renault Mograine as her right hand. Adventurers of both the Silver Hand and the Forsaken fought and killed the two, but Whitemane survived the attack and became the leader of the Scarlet Crusade until Adventurers sent by a Mysterious Crusader managed to kill the High Inquisitor once again.
After her second demise, Whitemane was raised into undeath by the Deathlord of the Knights of the Ebon Blade to become a member of the new Four Horsemen in the Ebon Blade's crusade against the Burning Legion.
