All seemed normal at a fair being held in honor of Twilight becoming an alicorn, but then one of the Mane Six went missing in a terrible fire. Everything that could have gone wrong, did. But, that's what you can expect when a group of ponies attempts to overthrow the throne.
Prequel: Birthday Dash (read at your own risk, I know it's terribly written)
If you don't want to read it, then I'll quickly get you up to speed . . .
The day before the first chapter was Rainbow Dash's birthday, and Queen Chrysalis attempted to drain the life out of her by having her Changelings pose as her ponynapped Parents (Spectrum Dash and Firefly) for the purpose of eliminating the Elements of Harmony's power and enabling her to take the throne. In the final fight, Rainbow Dash gets her wing broken. Enjoy!
Sequel: Broken Feathers: Frozen North
Edited now so it should be pretty good.
