As a train heads west into the wild frontier, six different mares have their sights set on its valuable cargo. When they collide, old grudges come to bear and bullets begin to fly.
Celestia decides to attempt to reform Discord, so she taps a pony with a similar background for the job. ("Keep Calm and Flutter On" as it occurs in the Petriculture AU.)
Twelve years after the Crusaders discovered their true nature, an ancient evil has returned. Celestia is hurt, magic is weakened, and Equestria is nearly lost. Now our heroes must find a way to fix The Hole In The Sun.
The Crusaders learn that they aren't like other ponies. As they uncover the secrets of their origins, the trio grow closer than ever, discovering not only their unique nature, but the incredible power that comes with it as well.
As a series of odd dreams plague Applejack night after night, she turns to the only one pony who can help her make sense of it all. But both sides of the story are as different as night and day, and nothing is ever as it seems in the world of dreams.
