Beneath this carefully maintained image, she operates as a cunning strategist willing to sacrifice her personal freedom for the survival of her people.

He arrives in Anne's court with an ominous message from the king of the korriganed and displays a disturbing mastery of shadow magic.

Louis is a pragmatic nobleman and former political prisoner who previously fought alongside the Bretons.

However, his respect for the young duchess complicates his loyalties as he witnesses her courage firsthand.

She views Anne strictly as a political asset and utilizes intimidation and political leverage to enforce her will on the Breton court.

Isabeau is Anne's younger sister, characterized by her youthful impulsiveness and fierce devotion to her family. While she understands the necessity of political sacrifice, she lacks Anne's strategic patience, often acting on raw emotion. Her desperation to save her sister leads her into dangerous bargains with unpredictable magical forces.

Henri is Anne and Isabeau's loyal half-brother and a steadfast protector of the ducal family.

Jean is Anne's counselor and officially appointed guardian, deeply protective of his royal ward.

He consistently prioritizes known, worldly threats over unpredictable supernatural dangers.

Elesbed is a practical and resourceful orphan who joins the ducal household as a companion to Isabeau.

She quickly proves herself to be a brave and deeply loyal friend.

The Korrigan-Queen is an ancient and powerful faerie who acts as a mysterious, challenging mentor figure to the Breton duchess. She guards the deeper magic of the Lost Lands and operates by logic wholly alien to human politics. Her guidance is often cryptic, designed to test the resolve and motives of those who interact with the faerie world.

Guillaume is a French envoy and general tasked with forcing Breton submission. He is an avid, passionate hunter, a trait that Anne actively exploits by fabricating a mythical beast hunt to distract him from his political duties.

Maximilien is the heir to the Holy Roman Empire, selected by Anne for a secret proxy marriage to protect Brittany. Though politically advantageous on paper, his reliability is compromised by his deep, haunting grief over his deceased wife.

Wolfgang is the Austrian envoy sent by Maximilien. He acts as the legal proxy for his master during the clandestine wedding ceremony in Brocéliande, performing the bizarre legal requirements to finalize the union before returning to Flanders.
