Now, one thousand years and a bit later, everything was how it was back then.
Well almost everything for Luna still hasn't found her daughter Selene who was only a filly when the Darkness took her.
But Luna placed the baby in an everlasting no time will move on sleep, which can only become undone by her own magic.

Please note: It has been a while since I have written a MLP story so please don't be too mad at how bad it is
