Hyzenthlay is extremely intelligent and has an unquenchable search for knowledge which she tries to satisfy by reading obsessive amounts of literature. She's also known to be more passive, peaceful, and docile and tries to avoid situations of conflict and violence. Lucy is probably one of the perfect, shining pure-blood examples of a Kivouachian. To humans she's labelled as insane or psychopathic, openly thinking that murder and violence are necessary or reasonable solutions.
