The six pony breeds of Equestria have been split by a ruthless tyrant, and their ties with the other nations have been severed, leaving ponies isolated and surrounded by potential foes. The Crystal Empire's magic has become corrupt with the new empress's rising and shadows creep in from the frozen north. Harmony has been forgotten. The magic of friendship has been lost. The time when Equestria, now called Enigia, was united is a time no pony remembers. Then a lone unicorn discovers a lost treasure in an ancient cave, and everything changes.
