Equestria is a great nation. It had lasted for thousands of years. However, like all great nations, it draws to a close. An ancient evil unlike anything anyone has ever seen before emerges from the shadows bent on revenge to destroy Equestria and the one thing that makes it great: Princess Celestia.
Only four ponies can save them all now. Unfortunately for Equestria, they may not know how.
Actually, they may not want to. Equestria sucks.
