10 years after Nightmare Moon’s fall, she returned now as a pony of her own. The kind heart of Luna no longer corrupts her heart and she is now a much more powerful entity. The Elements of Harmony are unable to stop her reign over Equestria’s balance and is now suffering the curse of eternal night. The impurities of her nature overcame her enemies. After that, Nightmare Moon has made each element go against each other. Their hatred has broken them apart and unable to show their faces again. The once peaceful world is now invaded by war, destruction, and disharmony. As everypony takes action, a few are left behind due to their lack of power. Including a certain cross-eyed pony.
