A Storybook is shown called, “The Elements of Harmony,” and opens to the first Page.  
Once upon a time, in an enchanted land of Equestria, there were two regal sisters who ruled together and created harmony for all the land. To do this, the eldest used her unicorn powers to raise the sun at dawn; the younger brought out the moon to begin the night. Thus, the two sisters maintained balance for their kingdom and their subjects, all the different types of ponies. But there wasn’t just harmony that was created for the land, for when there was the wicked dragon: the Dark Mistress! She vowed that she would shroud the world in eternal night and darkness of a terrifying sort. But the two sisters harnessed the most powerful magic known to ponydom: the Elements of Harmony. Using the magic of the Elements of Harmony, the two sisters have defeated her. The Dark Mistress along with her Dark Army have vanished without a trace and retreated to their kingdom: The Realm of Darkness. As the years passed, the two sisters continued their responsibilities and harmony has been maintained in Equestria for generations since.
