Terra Star is a Thestral, whose home is the Black Marsh. He was doomed to exile, right from the day he got his Cutie Mark, which is a White Wisp. He will now travel across Equestria, in search of a new home, and along the way will find great companions and friends, but terrible enemies.

EDIT: I decided to make my own cover art by splicing some images together, after realizing I was using the same cover art that NazoPureChaos used for his Elder Scrolls Equestria fanfic.
