Arnheid was a slave on Ketil's farm, serving as his personal maid and concubine while also caring for his elderly father Sverkel. She possessed a slender build with long wavy golden blonde hair typically styled in a halo braid, pale blue eyes, and thin light brown eyebrows. Her personality showed kindness, determination, and quiet resilience as she endured her enslaved existence.
Originally from a peaceful village, Arnheid lived with her husband Gardar and their toddler son Hjalti. Vikings attacked during the men's absence fighting a neighboring village over resources, shattering her life. The invaders murdered Hjalti to increase Arnheid's market value, as childless women fetched higher slave prices. She was captured and sold to Ketil, while Gardar was enslaved elsewhere. This trauma fostered unspoken resentment toward Gardar for leaving them unprotected.
At Ketil's farm, Arnheid occupied a distinct position. Unlike fellow slaves Thorfinn and Einar, she was never offered freedom despite Ketil's reputation for leniency. Her role extended beyond labor to include being Ketil's confidante and sexual partner, resulting in a pregnancy he encouraged to fulfill familial fantasies. This relationship involved inherent coercion; Arnheid maintained a detached, mechanical demeanor during their interactions, reflecting her entrapment. Ketil relied on her for emotional support while refusing to acknowledge her humanity or autonomy.
Arnheid's existence intertwined with Einar and Thorfinn. Einar developed romantic feelings, offering companionship that provided temporary solace. Thorfinn, recognizing her suffering, grew protective. When Gardar escaped his enslavement and arrived seeking her, Arnheid faced an agonizing choice between her husband and the fragile security of her unborn child's future. She initially chose to stay due to her pregnancy but ultimately assisted Gardar after witnessing his deterioration. Sverkel provided covert aid, motivated by his regrets about enabling Ketil's slave system.
The escape attempt ended in tragedy. Snake, Ketil's enforcer, captured Gardar. Arnheid freed him again with Thorfinn and Einar's help, but Gardar succumbed to his injuries after fleeing. Arnheid was recaptured. Ketil, upon returning from a failed confrontation with King Canute and consumed by fury over perceived betrayal and collapsed ambitions, brutally beat her. This beating caused a miscarriage and fatal injuries. In her final moments, Arnheid confided to Thorfinn and Einar that her life felt like an unending nightmare, expressing no desire to live in a world defined by slavery and violence. She died seeking peace with Gardar and Hjalti in the afterlife.
Her death profoundly impacted Thorfinn, crystallizing his commitment to create Vinland—a society free from slavery and warfare. Years later, Thorfinn established a settlement named "Arnheid Village" in her memory. The village featured a statue resembling her, symbolizing her enduring influence as a catalyst for his pacifist ideals.
