The freedom to walk between universes is a freedom denied from even the most skilled unicorns. To unicornfolk, it is less an achievable goal and more of a fairytale. But Twilight Sparkle, her brand new alicorn powers just beginning to settle inside of her, does not see a fairy tale. She sees a possibility that will impress both the other princesses and the citizens of Equestria. However, a test run of this spell does not go as perceived. Twilight Sparkle ends up an unwilling visitor in the mind of Princess Luna.
But she is not alone.
