1000 Years into the future, following the passing of Princess Celestia, Twilight Sparkle had assumed control of Equestria and the Sun.
Luna had lived much longer after her sister, being quite younger, however, when Luna had passed, in her final moments she had passed down much of her power to her young protégé, Stardust Nebula.
Imbued with Luna's ancient power, but struggling to control it, Stardust has a long future ahead of herself.
