After a bitter argument with his father, the leader of the Beartooth Mountain Pack, Heiye left with his best friend Neren in tow. After scouting out a den near the mountains for shelter, he slowly began to meet and invite new wolves, growing his newfound pack. As his pack grew, his territory shrank; after several aggressive encounters with his fathers' scouts, he decided to move his now 30-wolf-strong pack to the Taiga, where they found bountiful shelter, water, and prey.
