It's been many a year since Twilight took the throne of Equestria, and even though she's retired and is living happily in Silver Shoals, Celestia can't shake the feeling that something is off. That something is missing from her life. Facing conflicted feelings, she travels back to Canterlot to see how her former student is doing ruling Equestria in her and Luna's stead.
Little does she realize that this visit will be one that leads to much change in both her life, and that of Twilight Sparkle.
