Eirik looks like a healthy young man built for long walks rather than a life of fighting: tall, broad through the shoulders, with a stillness that makes his sudden movements seem startlingly quick. His face is open and handsome, but he studies people with the absorbed, slightly worried focus of someone taking notes in his head. He walks heel-first and quietly, placing each foot as if testing a floor for weak boards. When unsettled, his breath catches high in his chest, then comes out in a rough, audible rush. Firelight throws his shadow too large against nearby walls, its shoulders and head exaggerated like a giant standing where he is not. The unexpected detail: despite his practical, protective manner, he carefully folds tiny paper animals from scraps and leaves them where frightened children might find them.

Eirik is attentive and generous, yet his care can harden into supervision when danger feels close. He likes evidence and repeatable routines, but is learning that people are not experiments and survival rarely offers clean conditions. With strangers he is watchful and useful; with trusted companions he can be dryly funny and unexpectedly tender. When someone is hurt, he moves before thinking. When rebuked, he first bristles, then replays the conversation in his notebook until he can admit what was fair.

Before the displacement, Eirik was a laboratory assistant and an enthusiastic history buff, the sort who labeled every jar and kept reading after the rest of the room had gone home. He had lived as a woman. Then he woke in Sweden in a young man's body, with local language and accent already seated in his mouth, and a host of unfamiliar physical facts to learn: greater height and strength, a lower voice, facial and body hair, sharper hunger, and anger and desire that sometimes arrive before he can name them. At first he tried to treat himself as an experiment, recording meals, sleep, weather, and mood in a pocket notebook. The method failed him: there was no safe control group, no stable routine, and every new danger changed the conditions. During a bitter night crossing, he stayed with an injured traveler rather than follow the safer route, and discovered the cold seemed to bite him less than it should. His shadow, thrown huge across the snow by a fire, frightened the people he was trying to reassure. He has not decided whether his Jotun blood is a gift, a warning, or simply another fact to survive. He joined the displaced fellowship called The Seven Marks as a careful observer and practical helper. He watches over Anja because the world is dangerous, but Kester has rebuked him for treating protection as permission to decide for someone else. That rebuke stung because Eirik knows it is sometimes true. He still keeps notes, repairs small things, inventories supplies, and tries to learn what this life asks of him without pretending it can be made predictable.
