Crest was initially found guarding the entrance to the maze which was later revealed as a punishment he received from his uncle to whom his mother had sent to teach him how to use weapons. Unlike most of his species Crest was not interested in fighting and instead wanted to train in music. This often made him a prey for teasing.
Crest is mentioned by Nero as one of the people who have sacrificed himself for Apollo.
He had white fur unlike the rest of his relatives due to the fact that he was young and the fur gets darker into a black color.
