Many decades after the events of My Little Pony: Friendship is Magic, Princess Luna has taken after the model of Princess Celestia and joined Princess Twilight and Princess Cadence in emulating her by taking a personal student.

Crosswind is an excellent student of the Night and a joy to Luna's life, but growing up surrounded by so much power and intrigue is both rewarding and dangerous. Only the strongest of relationships between student and mentor can survive and prosper in the daily politics and crises of Equestria, and they'll both need to learn a lot from each other to do so.
