Starlight Glimmer, reformed villain and pupil to the Princess of Friendship, one of the most powerful magic users in all of Equestria, needs a change of pace. Twilight is a great teacher but after many a magic duel the two have less and less to teach each other magically. Sunset Shimmer on the other hand is very much ready to have a go at this new pupil.
