A few short years after Nightmare Moon was sealed into the moon, four of Luna's friends make a major request to Celestia. They claim that Luna is fighting her alter-ego and that Celestia's seal will be stronger if they help her fight Nightmare Moon. Lunar Veil, a unicorn who loves the stars can see the moon for what it really is and wants nothing more than to help her friend. Swift Gale, her mate, a pegasus stallion would follow her to the ends of Equestria, and apparently even the moon. Silver Fern, a quiet but poignant Earth pony misses the kind princess. And Triumphal Lance, a unicorn mare from the Lunar Guard still feels the loyalty she had when Luna was present.
