My Little Pony: A New Generation really didn't explain a whole lot in terms of what happened between G4 and G5. There are rumors floating around based on Equestria Girls and it's memory stone being in the background in the movie, along with Grogars' bell, but we still have no solid information yet.
What do you think happened between the eras to cause a complete memory wipe of horse society? Or is it possible that we are looking at thousands of years here and stuff just changed naturally with such a long time frame?
