Savanna's lost her home and everyone she's grown up with to shadowhiders (shadow/darkness-controllers). Her only consolation was finding her older sister Carrolee; who brought down the shadowhider organization with her. But Carrolee IS a shadowhider herself and left Savanna all alone in Chicago while Carrolee escaped to the outside world. Savanna, in a fit of rage, swears to hunt down and kill every former shadowhider from Chicago, including Carrolee. She regrets her decision ever since, until certain events in China twist her to become what she hates.
