(Prequel to my series 'The Elements of Harmony') Luna is gone, Celestia is a wreck, and Equestria is falling into a darkness that was supposed to be stopped with Nightmare Moon's banishment. How will Celestia cope with the only pony who has survived the years with her being banished? Will our beloved Princess of the Sun ever recover from her loss, and can a certain five star general help her to do that?
