Many generations have past since Nightmare moon was defeated by the mane six using the elements of harmony. To many ponies of Equestria, it is just another story in a history book, but to Night Spell, it is everything. She has spent all her life studying Equestria's history under Princess Twilight, the reigning leader and the former element of magic. Whenever Night Spell doesn't understand something she reads in her books, she can always know that Twilight will have the answer. But when Night Spell asks about the Elements of Harmony, Princess Twilight seems very disturbed about the young filly's passion on historic artifacts. But even more surprising is the hidden page on the elements of harmony Night Spell finds in one of the old history books.
