Diem is a strong-willed healer from a mortal village. After the gods choose her as the new Queen of Lumnos, she moves to the Descended palace to protect her people.

Throughout her early days at court, she tries to control her dormant magic while balancing her mortal roots with her new royal duties.

Luther is the prince of Lumnos and the most powerful of the Descended. He serves as the Keeper of the Laws, enforcing the Crown's rules across the territory. He acts as Diem's primary protector and guide at the palace, constantly swearing his allegiance to her. He harbors deep secrets about his past and his true feelings regarding the mortals.

Iléana is a proud member of House Hanoverre. She firmly believes Diem is a mortal imposter and actively contests her right to rule Lumnos. She desires a political and romantic union with Luther Corbois, viewing Diem as a direct obstacle to her ambitions.

Remis is the brother of the late King Ulther and the calculating patriarch of House Corbois. He previously served as the Regent and understands the political games required to hold power. He offers to act as Diem's advisor to shield her from rival houses, though his true motives remain hidden behind a polite exterior.

Eleanor is a kind and thoughtful Corbois cousin who quickly befriends Diem. She provides a warm welcome to the palace and patiently explains Descended customs, family histories, and royal expectations. Diem trusts her enough to name her as a primary advisor.
