As Civil War breaks out in Equestria, lines are drawn between Princess Celestia's Holy Solar Empire, and Princess Luna's New Lunar Republic.

The war pits sister against sister in a battle for land, survival, and freedom in the once-peaceful plains. Families are torn apart, homes become broken, and lives are ruined. Through this war, the Elements of Harmony themselves are split and must fight on opposite sides, doing their best to end this war as quickly as possible.
All the while, WindChaser, and his friends must find their way in a war where they seem to be nothing but cannon fodder on the battlefield.
Will War tear apart the world as we know it? Or will Peace truly reign supreme?
