Fallout Equestria side story.
Two young stallions, bored out of their minds in a small frontier town far to the west, join a courier service and are sent to deliver a package to the New Neighgas strip but what has started as a simple delivery job has taken a turn... for the worse... This is the story of Clover as he crosses the merciless, barren desert and his fight for his sanity and his life.
