Freya is a twenty-year-old woman living in a Norse-inspired society, secretly harboring the magical abilities of Hlin, the goddess of protection. Bound in an oppressive marriage to a wealthy fisherman, she longs to fight as a warrior but hides her powers to avoid being exploited by ambitious leaders. When her identity as a prophesied shield maiden is exposed, she is forced into the political machinations of rival warlords who wish to use her to unite Skaland.

Bjorn is the son and heir of Jarl Snorri, known throughout Skaland as a fearsome warrior and a child of Tyr, the god of war. He wields a magical fire axe in battle and possesses a confident demeanor that masks a traumatic childhood spent as a captive in Nordeland. Assigned to train and protect the prophesied shield maiden, he battles his growing attraction to his father's intended bride.

Snorri is the ambitious jarl of a Skaland territory who dreams of becoming the king of a united realm. Driven by a twenty-year-old prophecy, he ruthlessly seeks to control the shield maiden to secure his own rise to power. He relies on his rhetorical skill and political leverage to bend others to his will, often prioritizing his geopolitical goals over the safety of his people.

Ylva is Snorri’s first wife, the lady of Halsar, and a volva capable of wielding powerful runic magic. Deeply loyal to her people, she harbors intense resentment toward the prophecy that forces her husband to take a second wife. She is fiercely protective of her son, believing he should inherit his father's position instead of his older half-brother.

Harald is the formidable King of Nordeland and the primary geopolitical rival to the jarls of Skaland. He is known for his ruthless tactics, including the previous abduction and imprisonment of a young child of Tyr to neutralize his enemies' military advantage.

Gnut is a rival Skaland jarl who operates from a forbidding fortress in Grindill. Unwilling to be ruled by anyone, he violently opposes the prophecy that would unite the territory under a single king, preferring to kill the shield maiden rather than see her empower his enemies.

Vragi is a wealthy fisherman in Selvegr and a child of the sea god Njord, granting him control over fish. Despite once saving his village from famine, he is now universally despised for his abusive nature and tendency to hoard the sea's resources. He holds significant leverage over Freya's family due to his financial influence.

Geir is Freya’s older brother, a twenty-two-year-old warrior who rides in Jarl Snorri’s raiding bands. He pressures his sister to maintain her miserable marriage to secure their family's financial stability and his own military standing. Though he cares for Freya, his reliance on the jarl's favor often puts him at odds with her well-being.

Kelda is Freya and Geir's mother, a woman who prioritizes financial comfort and societal standing over her daughter's happiness. She arranged Freya's marriage to a wealthy but cruel man to ensure her own security. She carries secrets regarding the divine circumstances of her children's conception.

Ingrid is Freya’s best friend from the village of Selvegr. She provides emotional support to Freya during her oppressive marriage and shares a mutual affection with Freya's older brother, Geir.

Bodil is a famed warrior and the only female jarl in Skaland. As a child of the god Forseti, she possesses the magical ability to distinguish truth from lies. She respects martial prowess and offers to train the shield maiden, believing in loyalty to the prophesied figure rather than to any ambitious chieftain.

Steinunn is a skald, or bard, and a child of the god Bragi. Through her ballads, she can grant listeners vivid, immersive visions of heroic exploits. She travels with the jarl's forces to chronicle the shield maiden's journey, though her invasive magical storytelling sometimes causes distress for those involved.

Liv is the resident healer at Snorri's stronghold. As a child of the goddess Eir, she channels divine magic through a specialized moss to mend severe injuries and administers narcotics to ease pain.

Leif is the fifteen-year-old son of Snorri and Ylva. Despite his mother's intense desire for him to inherit the title of jarl over his older half-brother, Leif maintains a friendly and caring relationship with his sibling.

Saga is a seer and the mother of Snorri's eldest son. Twenty years ago, she delivered the prophecy regarding the shield maiden who would unite Skaland. Her visions of the future shape the political landscape long after her presumed death.

Tora is a child of Thor who wields bolts of lightning as weapons. She fights as a mercenary or allied warrior, providing devastating magical artillery defense for rival armies resisting unification.

Ragnhild is a spy sworn to King Harald and a child of Hoenir. She possesses telepathic abilities that allow her to send visions to anyone holding her tokens, though her captor ensured she could only serve him by cutting out her tongue to use as her token.
