Harmony is a strange thing. It is unique to everyone, it is not something that can be given or forced, and it cannot exist without chaos. Instead, it must be found through a personal journey fueled by the burning questions kindled from the flames of chaos. You cannot simply make someone harmonious, something Princess Luna knows all too well.
To many, it seemed as though the Elements of Harmony had simply used magic to purge the monster of Nightmare Moon from the sweet Princess Luna. Such a simple story, but how much do the ponies of Equestria, even Celestia and Luna, truly know about the inner workings of the Elements' ancient and powerful magic? What if their power dives deep into the unfathomable depths of a being's soul and mind that cannot be perceived by others... or what if they had never worked at all?
This is the full story, the truth, behind the events of Nightmare Moon's journey to find harmony. It's a tale that is astonishingly more intricate than what has been previously told, and it is most likely something more profound than most would ever dare to imagine.
