Celestia and Luna have jointly ruled Equestria for centuries, and the land has been stable and prosperous under their rule, yet both of them have been slowly growing less and less enthused as the demands of their subjects begin to mount. As the two princesses approach their breaking points, it seems that the only thing that will stave off the destruction of Equestria is that both goddesses seem more focused on each other than the world at large. In the midst of this crisis, Twilight Sparkle, a newly commissioned officer in the Royal Guard, seeks what may be the only viable solution to this problem: locating the Elements of Harmony before either goddess can destroy them.
