Despite her lack of wings and magic, Collateral has made a name for herself where no Earth pony has before: as a member of Equestria's elite squadron of Vertibuck pilots. Orphaned by the Great War and alive for its stunning conclusion, Collateral finds herself thrust into a sprawling, depraved wasteland where civilization and civility have all but ceased to exist. She must learn how to live without her wings of steel and adjust to life on the other side of the bombs, or else risk losing what little ponymanity she has left.
