Civilizations spanning across the multiverse from past, present, and future find themselves pulled together from an unknown force. The survivors of what is now known as the 'Cataclysm' soon facing a very important question: Who will come out on top?

Princess Cadence is hoping to learn more about pony's boundaries and to get some interesting stories to tell the other royals, mostly the latter. To do this she is making all the citizens of Equestria love a single pony for a day, chaos ensues.

The princesses have always been known as at least somewhat immortal, so how do they cope when their loved ones pass on? Perhaps those born as alicorns will take it just fine but how will Twilight cope when her friends die out?
