Long ago a powerful, dangerous entity travelled Equestria. One with no sense of right or wrong, empathy or morality. One who almost broke Equestria in half at his whims before inexplicably surrendering and allowing Celestia to imprison him.

Now, at long last, he moves again.

May God have mercy on Equestria's souls.
