A long time ago in the magical land of Equestria, ponies changed the world. They put their lives on the line to bend the arc of history and mold the present and future of not only their country, but the entire world. They were ambassadors, princesses and princes, warriors and scholars. Everything they did, they did to preserve and propagate their way of life.

None of that matters now, though. Their stories are largely forgotten, their lessons nothing but dust on the winds of history. Their buildings still stand, mostly deserted ruins now. Other than that, their only legacies are the problems they left for the new age to deal with.

Sunny and her friends thought they had a pretty good grasp on those problems, and they were working day in and day out on ways to solve them. Then another one rears its ugly head: an ancient city emerges from the depths of time and unleashes an old horror upon ponykind once again.
