History is written by the victor; this is a fact that everyone knows. What no one knows though, is that the Princesses have a secret: a deep, dark, terrible secret that could very well doom Equestria. Millennia ago, an evil king ruled the land known one as the Equestrian Empire. With the help of his right-hoof Draconequus, King Eclipse enslaved millions, toppled governments and stole entire countries... until they were defeated by Celestia and Luna, and Eclipse was erased from history.

History, however, has a way of repeating itself. Eclipse has returned, and now seeks vengeance for thousands of years of imprisonment. Join Twilight Sparkle and her friends as they search for their missing leaders, uncover traitorous plots, and seek to defeat an enemy they know nothing about...
