After defeating Tirek, Cozy Glow, and Queen Chrysalis with the help of her dear friends, Princess Twilight Sparkle is about to truly ascend to the throne and rule over Equestria in both Luna and Celestia's stead. Unfortunately, her ascension isn't what she was expecting, and a shocking revelation is made.
