2019. The world that Sunset Shimmer fled to years ago has now turned into a dustbowl of a wasteland. With invaders having reduced their home into nothing but rubble, Sunset Shimmer, her friends, and many others have fled Canterlot and built themselves a cooler, more mature society. They call it, Apocalypseburg. Show any weakness and you'll be eaten alive. This new life has toughened and hardened everyone... well, almost everyone.
