So I was thinking that there could be a My Little Pony: Friendship Is Magic story, where the fans align their wishes for the show,and release Nightmare-y Sue, who then submits all of Equestria to eternal fanfiction. Until the ponies manage to find the Elements of Style: grammar, composition, form,spelling, vocabulary, and the sixth element which is a complete mystery, but is ignited by a spark when the other 5 are present: The Element of TALENT.

EDIT: If you don't know what I'm on about, go watch the pilot (first two episodes) of My Little Pony: Friendship Is Magic. And also know about this book: http://www.amazon.com/dp/020530902X
