In this alternate timeline, Tirek has been successful in his attempts to take over Equestria. The princesses, Discord, and the former element bearers along with Spike and Shining Armor are locked in Tartarus. Equestria is now controlled by a tyrant and resistance has proven futile.

But Tirek has made one crucial mistake, he has left Discord alive. While Tirek’s rule begins to turn Equestria into a nightmarish dystopia, Discord is making plans. The seals of Tartarus are slowly breaking around Discord and when he’s free he plans on fighting Tirek with every dirty trick he can muster, whether it involves psychologically tormenting Tirek or giving Equestria’s now magicless pony’s weapons from worlds unknown. Tirek has crossed a line and Discord no longer has to worry about his conscience when it comes to fighting another monster.

Battle lines are being drawn and opportunists from around the land flock to Tirek’s banner. Discord and the remnants of the Equestrian military are the only hope of a broken world. There are no elements, no easy paths to victory this time. A ruthless battle of immortals is coming, and the ponies of Equestria are going to have to fight for the happiness they once took for granted….
