Equestria is peaceful.

Everything is perfect. Or at least, it will be. One day. Every little event will go exactly as planned, and life will go on in nearly perfect harmony. Equines and Griffons and all sorts of races living together in peace.

With only one, teensy, tiny bit of a miscalculation.

It has been a thousand years since the shadows of Equestria were cast back into the void from which they came, with broken dreams laid to rest or forgotten and scarred hearts healing ever so slowly, the whole world itself had more or less moved on with the needless marring on its own history, and evolved to be far more peaceful.

But they didn't catch every bit of darkness.

A thousand years later, not a King Of Darkness, not an heir, not a tyrant, but a lost little 'prince' returns with nothing more than his forgotten title and a few scattered subjects, and with his return, it would seem as if the turmoil of the world begins once more, as the princesses suddenly disappear.

Now follow the aftermath of a thousand years of hiding as Twilight Sparkle and the mysterious new interloper soon begun a hunt for the shattered vault of a long forgotten people. One, trying to piece together the history of a new world, the other only trying to plunder it.
