Twilight Sparkle sent many letters to Princess Celestia detailing what she learned about the magic of friendship. These letters, along with many other writings, were collected into a book. The "Book of Friendship," as it was called, contained many teachings of love and tolerance, sharing and caring.

And an organization based around this book sprang up, called the Fraternity of the Joyous Friends of Princess Celestia. And whenever a Brother (or Sister) comes of age, it is their task to spread the word of the magic of friendship across Equestria and beyond.

This is the story of Brother White and Brother Scroll, two young stallions who have been tasked with spreading the word to Earthquake Island. Unfortunately, Earthquake Island is not particularly interested in party games.
