Earth has faced terrible things since the Event transformed all living humans into ponies and scattered them across time. Equestria's own demons nearly wiped out civilization more than once, and devastating internal war nearly finished the job.
But now the worst threats are gone, the weapons ponies created to survive them are more dangerous than ever. The superintelligence Athena now rules the world, absolute authority over all civilization. With her power and intellect, she drives the survivors towards greatness, regardless of the body count along the way.
But there are ponies who resist, who yearn for something better. Jackie is not one of those ponies. But maybe they can get her help. It isn't like they have anywhere else to turn.
