Two stories collide in a windstorm, and a secret is discovered. Will the trio be able to beat the darkness? Or, more importantly, do either of the stories have their driver's licences and insurance?

Well, Derpy tried. Besides, it was only a small error! However, it comes with disastrous results - a pegasus gets a broken wing, an army is uncovered, and this fanfiction was begun. (Save yourselves)

This is a collaboration between myself and Trombone15 - my first collab. Expect oddness.
