While reading through her dad’s old history books, Sunny Starscout comes to a horrifying realization: The ancient legend of Nightmare Moon is in fact real, and she’s due to return to Equestria on the eve of the 1000th Summer Sun Celebration to bring eternal night.

To make matters worse, the 1000th Summer Sun Celebration happens to be tonight.

Luckily, there’s a solution: Six magical artifacts known as the Elements of Harmony could be the key to Nightmare Moon’s defeat. But how is Sunny supposed to find them when they’ve been lost for generations? And why isn’t the Princess not doing anything about the danger?
