While Luna was Nightmare Moon she cursed this land; condemned it. Just in case her sister would find a way to prevent her from turning Equestria into a world of eternal darkness, Nightmare made a way that the world would set itself into darkness. But now after Princess Luna has returned to her original self, the reckoning is still upon them and with the removal of Nightmare Moon, no pony will be able to control it. It will be up to the Elements of Harmony to find a way to bring the world back to the light. Along with their newest friend, Electra Storm, who isn't your average Pegasus.
