There is a certain darkness in the Princess of Friendship's mind. A darkness that wants her to control and recreate the minds of others. And once she picks up a book on hypnosis and mind control, the darkness can break free. Free to control.
Free to control all.

It was a semi-normal day as Twilight was mapping out the Everfree forest. She didn't know why, but she doesn't care. She told Spike to leave when she might get hurt, but she didn't care. Until see comes upon a magic cave that will charge her life forever. Now she wants to share her new found power with her friends.

Takes place right after games ponies play.
