Before the Books
Tavis and Cletus were out hunting while their mother Skye was sitting on her egg which was an hour from hatching. When they came back from their hunt, Skye had mysteriously disappeared and the egg had already hatched, but the owlet was nowhere in sight. They found their mother's body, but they never found their little brother. It is said that their father was killed by the High Tyto before Kludd. After Tavis and Cletus lost their mother and brother, they went to live underground in the Desert of Kuneer.
The band was surprised to find Twilight's brothers, one of them being Cletus.
Cletus is very brave, and like Twilight in many ways.
