An alternate universe story, in which Twilight Sparkle was born a pegasus, not a unicorn. Because of this, she isn't Princess Celestia's personal student at the School for Gifted Unicorns, and she can't wield the Element of Magic. Can she still help save the world from Nightmare Moon? Or will she fall under the dark powers of nightmares?
This was somewhat inspired by Rainbooms and Royalty, a story in which Princess Celestia picks Rainbow Dash to be her personal student.
