I really have no idea what to write here. Summaries are not my thing. All I can really say is:

The Elements of Harmony have been stolen and the Princesses have selected Luna's flight student to retrieve them. But Rain Flash cannot do it alone, he will need the help of an ally that resides in Ponyville.

That's about all I got. Read the story itself if you want to get the real idea of what it's about. Feedback is good.
