Fury's father Markus is Katagaria and his mother Bryani is Arcadian. Bryani sent her three Katagari pups (Anya, Fang, and Vane) to live with Markus and kept her three Arcadian children (Dare, Fury, and Star). When Fury turned Katagaria at puberty, his pack sentenced him to a timoria, which is being beaten and left for dead. He then joined Markus' pack but did not reveal his true identity to his father or siblings.
