Thanks to her efforts in foiling Algard’s plots, Anisphia’s right to the throne is restored, and the former oddball princess is now future queen of the land. All of a sudden, it’s like she’s a different person—working tirelessly on government affairs to prepare to lead the kingdom and even throwing her beloved magical studies out the window.
