Oak was the first to join Silva, and an avid supporter of her becoming leader. They met as travellers, and Silva suggested the idea of starting the Great Wyvern pack, to which Oak avidly agreed upon. The two worked together and founded the beginnings of what would one day become a thriving community.
Oak has sired many pups, though few remain in the pack. Though he has met many females, he has yet to find one to settle with for the rest of his life.
