Upon arriving in Ponyville to live with her father, regular earth pony Vanilla Twilight didn't expect to experience anything different or unusual. She was just boring, bland, and uninteresting, so what was there to expect? But once she caught the eye of the mysterious Marble Sparkle, her life was about to change forever...

What does it mean to truly be the Princess? To always know what to say, how to fix any problem, when to act for the good of your subjects over yourself? If this is the truth, then Princess Celestia certainly was not ready to become the Princess in the first place. Now, as she sees herself reflected in the new Princess Twilight, she decides to tell Twilight the story of her past in the hopes that she might learn from her successes along with her failures.
