I see you already have a Willow :') 

Name: Crystal NoLastName
Age: Her host is 22 Earth Years :)
Race: Soul!
Bio: Crystal has inhabited many planets... She is unusually mean-spirited for a soul, and likes getting her own way. She wound up on this planet after being exiled from the last, where the souls were trying to incorporate peace in an otherwise hostile world. The others felt that her attitude would disrupt all of their hard work and that Earth would be a much more suitable match for her abrasive personality.
