Once Equestria was under the rule of two princesses, Princess Sunset Shimmer and Princess Twilight Sparkle. If one said the two loved each other no longer than five-hundred years ago, one would say that they were insane.
As of now, Equestria is split in two and at war. One side is led by Princess Twilight Sparkle, and the other being lead by none other than Princess Sunset Shimmer.
