Nearly two thousand years before the founding of Equestria, the mortal races of the ancient kingdoms rose up against the Alicorn Imperium that had ruled over them, treating them as little more than slaves for millennia. One by one the alicorns of the Imperium were hunted down. Most were executed for their crimes against those they considered 'lesser' ponies. But a few of the most powerful were imprisoned for all time. They should have killed them all.
After nearly three thousand years imprisoned, one of them has broken the bonds of her prison. Now she seeks to reestablish the dominance of the alicorn race, and overthrow the disgraceful excuses for alicorns that are currently in power.
