Things can go wrong in Equestria, but not quite as wrong as this…

As my first fanfic, it may be a bit terrible, but I would like anyone who has something to say about it, please do. Anyway, On with the description.

One day, a mysterious pony sends a letter to a certain few… not friendly characters, and asks them to meet her.

(I don't know how to write a description without spoiling stuff sorry!)
