Based on the villain song of the same name, The Moon Rises by Ponyphonic, which you can listen to here: http://www.youtube.com/watch?v=kPjVCIX5Fvs&feature=channel&list=UL
After years and years of serving ponies across Equestria, after defeating Discord and after restoring Harmony, Princess Luna is happy with her life. She understands that ponies need to use her night to prepare for their coming day, and she lives content with the knowledge that they all can appreciate her nights like she does if they so wish.
Come some careless remarks and ill timed events, Luna begins to doubt herself and the value ponies place in her night. As has been done before, this is a story detailing the fall of Luna from grace and of her becoming the villainess known as Nightmare Moon.
As is my policy, OC's are background characters only and but one appears to fill out the ranks of the cast (Luna, Celestia, Blueblood's ancestor and Starswirl the bearded would be a small cast, no?).
As this is my first serious story, I would greatly appreciate any feedback I could receive.
