Snaproll is a young flier working for the Royal Mail Service, marking time and trying to make his way in the world. But in this day and age, when letters can be sent by magic and dragon, he has to step up and prove-to Equestria and himself-a simple mail pony can do the job better than someone with a magic gimmick and a few dragons. If he fails, not only will he be out of a job, but so will countless pegasi.

Not that there's any pressure or anything.
