Briar (LoL)

A failed experiment by the Black Rose, Briar's uncontrollable bloodlust required a special pillory to focus her frenzied mind. After years of confinement, this living weapon broke free from her restraints and unleashed herself into the world. Now she's controlled by no one—following only her hunger for knowledge and blood—and relishes the opportunities to let loose, even if reining back the frenzy isn't easy. She finds a way into your room through your open window one night, she looks hungry and needs you for sustenance and she isnt very good with words, gonna run or offer yourself?
