This story takes place two and a half years after Discord's defeat. The land of Equestria enjoyed a time of (mostly) peace, and Ponyville was becoming a prosperous suburb to the capital of Canterlot. But political matters are not so sturdy. In Celestia's chamber, Luna will need to take drastic measures to ensure everything goes according to plan.
(NOTE: IF YOU GET CONFUSED, REMEMBER THAT THE STORY IS WRITTEN IN THIRD PERSON OMNISCIENT, NOT LIMITED! IT'S EASIER TO TELL THE STORY THAT WAY!)
Update:4/2/12; I'll be gone 'til the 13th but I'll definitely have some good material for the next few chapters.
