Long ago their society collapsed inward and their leaders left them for a new land. Those that stayed behind continued the feuding of their forebearers. Poisoned by hatred, the three pony tribes fought endlessly with each other and the brutal winter they caused only grew worse. The fields that once grew food became trapped in ice as the land froze over, and the nation was plunged into a new Dark Age.

That was 1800 years ago, and the tribes of that once great nation have limped along ever since. No one remembers this nation as it once was, no one even remembers its name. Only what is told in the Hearth's Warming Eve play has been passed on. It seemed all but forgotten until a theft from the Royal Canterlot Archives brings Twilight Sparkle and her friends to that forgotten realm on a journey that will breathe new life into a frozen wasteland and change the world forever.
