Long ago, Celestia and Luna waged war against each other. It was so fierce that it threatened to destroy the both of them. But, due to the constant clashing and destruction led to Luna having Celestia being cast out, never to be seen again. For thousands of years, peace begun to come back to Equestria, but a greater threat looms on the horizon, one that nobody could have seen coming. It seemed that nothing could have been done to stop it.
