Description

Rather above middle height, she possesses a slim build with an absolute pallor of skin that gives her an ethereal, ghostly quality. Her dark hair frames dark eyes often flushed with crying, and her bloodless lips underscore her fragile intensity. She exudes a strong character through self-restraint, her presence both poised and haunted in Victorian dress.
