Six years ago, a strange craft fell from the sky. The creature that fell with it has been living secretly as a pony in Ponyville ever since, unaware of its true nature.

Now, six years later, Big Macintosh has disappeared, and the creature from the sky is the only one who can save him. The secret must be unveiled, no matter the cost.

A Doctor Who universe crossover fic.

My first (non-terrible) fic, so tips would be great.

Suggestion on categories would be appreciated as well, as I'm not really sure how it works.
