Fighting Fire with Fire
A talented mage but frustrated that the male dominated field of study was largely closed off to her. She managed to find a few teachers that would teach her but rarely did she learn much before it turned out that the teacher wanted something in return that she was unwilling to give. In desperation she turned Tzeentch, the chaos god of magic. She learned a great deal and proved herself worthy. For her service to him Tzeentch changed one her arms into the arm of a flamer daemon. End result she cut off the offending arm and ran immediately to search for worshipers of Malal. She hates Tzeentch for what he did to her and felt that the only way to hide from him was to hide and fight him within chaos.
