Dear Twilight Sparkle,

In your hooves, you hold Starswirl The Bearded's masterpiece. He was unable to finish it. I have full confidence however, that you will be able to finish it.

Your Teacher,
Princess Celestia

Princess Celestia has a mission for her faithful student Twilight Sparkle, to finish one of Starswirl's unfinished spells. But when Derpy Hooves accidentally flies into the library, trying to escape an force invading equestria, and slams into Twilight, interrupting the spell, Twilight and Derpy are thrown into a new world. Watch how they adapt to this world, and along the way, make new friends, solve problems, and maybe, find love.
