For years, Sunset Shimmer has happily held her place at Celestia's side. She was her prized student, her number one prodigy. In return, Celestia was Sunset's world, her passion and drive. However, with time and age come change, and Sunset cannot take it any more.
She doesn't understand why Celestia won't look at her any more, why she is so enthralled by the talent and simple nature of her newest discovery. All she knows is that as much as she may aspire and hope, she'll never again be the object of Celestia's interest.
Sunset Shimmer intends to leave, and she has no plans of returning.
