Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

This story is a sequel to Seven of Six: A Screaming Butterfly

Twilight Sparkle is a unicorn prodigy, her special talent of magic allowing her to wield all manner of the arcane arts with ease. She is an SGU graduate, has connections with the Royal Guard, knows Princess Celestia, and is a mother to a juvenile dragon.

She's also apprenticed to Discord, Lord of Chaos and Disharmony.

And he has a mission for her. A fallen alicorn named Nightmare Moon will soon return to bring eternal night and assured death to all the world. It's up to her to retrieve the Elements of Harmony and stop her.

Join her as she explores a familiar town, befriends familiar ponies, and completes a quest that's as old as the fandom itself, but with a twist.

A retelling of the pilot episode Friendship is Magic, but set in one of Starlight's alternate timelines.
