A wolf who was adopted into the pack by Promethium and Serenity, two very well known wolves.
Jasper is a good wolf who keeps his hunting party's mood up when times are tough and eases tensions between Moon Chasers and Peak Seekers. Jasper's successor is Draco who he has mentored since puppyhood, becoming a sort of father figure to Draco as he understood entering a new pack as a pup is a nerve wracking experience.
