Princess Twilight Sparkle invents a new way to travel between universes. On the maiden voyage with her best friends, something goes wrong.

Her discovery resurrects a secret from her past, one she has only shared with Princess Celestia. When Twilight learns of the price required to return things to normal, she is left with an impossible choice.
