I guess we should talk about her role. After her mother retired from the throne (sometime in between the the 2 parter and the epilogue of the series), Skystar became the new Queen. While she had matured since, she still retains that bubbly and energetic personality she is well known for. She still keeps in contact with her close friends and her mother, despite her royal duties. She knows she would make her mother and late father proud.
As for Novo, I like to imagine that when she retired, she moved to Silver Shoals to be with Celestia, so that way they catch up with all the years that they were apart.”
