The cause of Luna's transformation into Nightmare Moon is a mystery. Many ponies have their own theories of what happened, each different in their own way, but making sense at the same time. This story, fillies and gentlecolts, is what I think happened, is it true?..... Well, that's for you to decide for yourself.
This is my first story on here, I hope it doesn't turn out too bad and you guys enjoy it. Please, if there's anything you see that doesn't make sense, feel free to comment about it. I don't want to leave you confused with stuff or anything... And could you give me feedback on how it's going?... If you don't mind...
