(First fanfic, ever, for anything)
On the Wings of a Pegasus is about the journey of a Pegasus, Crimson Flair, and her two Earth Pony friends, Hexa Byte and Metal Forge. It takes place far, far into the future, in a land called Mestrialus, which is just what the Unicorns renamed it to after they took over in a violent coup. The land was known as Equestria.
The only other thing I can think of mentioning here is: no cliche Elements of Harmony ending!
