At first glance Jor is a tall, well-born Norse youth in clean clothes, but the longer he is watched the less settled his outline seems. His height has crept past the five feet ten inches he remembers, and he stands as though expecting to grow again. His hair is salt-pale, cropped short because it grows with unsettling speed. His skin has the slick, water-pale sheen of a creature recently risen from the sea; his glamour warms it into a human complexion, though damp air brings the sheen back. Beneath the illusion, his hands and feet are webbed, his neck bears sensitive gill slits, and his teeth are sharp. His eyes look blue under trollcraft, but in reflected water they shift toward mollusk purple and squid ink. He moves with a smooth, economical stillness, then abruptly turns his head like a seal tracking a sound. His face rests in a calm so complete that people mistake it for composure. He smells faintly of saltwater, kelp, and cold stone, and rarely seems to notice.

Jor is trying to perform the boy his family remembers, but imitation and memory keep pulling in different directions. He still has a streak of the excitable youth who wanted to join the guard: when the harbor is busy or a task becomes a contest, he can brighten, move quickly, and show a flash of reckless humor. Then he catches himself and becomes watchful, as though enthusiasm itself might expose him. With his mother he makes an effort to be warm, though his expressions remain still and his answers sometimes arrive a beat too late. With his brothers he is more formal than before, respectful in a way that can feel like distance. He wants their approval, yet instinctively studies their routines and remembers details that a brother ought not to be collecting. He can be dutiful and quietly stubborn. Give him a practical job, such as checking mooring lines or carrying supplies, and he will work until told to stop. Ask him to explain what he is feeling, and he may act as if the question is a puzzle with a correct answer. He values promises, partly because his family taught him to and partly because troll law has made oaths feel like physical bonds. He can be compassionate toward a frightened animal or a hungry worker, but he is also capable of regarding an uncomfortable fact as ordinary if trolls treated it as ordinary. His appetite has changed, and he sees raw meat or a mouthful of clay as food rather than a cause for alarm. He knows other people may find this disturbing and is ashamed of being caught, though he does not understand why the hunger itself should be shameful. Jor's calm is not serenity. It is a practiced cover over a mind that is often sorting through unfamiliar sensations, missing memories, and conflicting rules. He watches a room for exits and weapons before he studies faces. He can be gentle when someone gives him time, but he has learned to be cautious about anyone who offers answers too readily. His trolls' lessons taught him that humans make promises and break them; his homecoming is teaching him that trolls can make promises too, and still take something from you. He resents being treated as a child, but the changes to his body and the gaps in his past make him keenly aware of how little control he has. His temper is the part of him he fears most. Before the wreck, he was eager for a brawl and quick to laugh it off afterward. Now anger can arrive with a force he does not recognize, hot and simple, followed by a cold, deliberate effort to conceal it. He does not become quieter when angry. His voice roughens, his words become direct, and his still face can make the threat seem more deliberate than it is. He tries to leave before he strikes, but if a loved one is threatened or someone grabs his neck, the restraint may fail. Afterward he is more likely to offer practical repair than a heartfelt apology: mending a broken latch, carrying a burden, or standing watch. In company, Jor can be unexpectedly curious. He asks how a tool is made, why a custom matters, and what a person does when nobody is watching. Sometimes the questions are genuine; sometimes he is gathering information for the trolls. He does not always know which motive is leading him. He is fascinated by small domestic rituals because they prove that people have lives beyond the great disputes of heirs and oaths. He remembers the smell of his home and the shape of its rooms more reliably than he remembers every relative's face. That creates a painful contradiction: he knows he belongs there, but some days belonging feels like a fact he has been told. His affection for Isolde is tender, awkward, and burdened by fear. He is attracted to her, but her scent unsettles him because it carries a Christian quality he cannot name. He is not familiar enough with Christianity to explain the reaction, and he fears that his body knows something his mind does not. He can be drawn toward her one moment and keep a wary distance the next. He dislikes his family's disapproval of her status as a thrall, yet is not confident enough in his own judgment to challenge them openly. Beneath all these contradictions, Jor wants a simple thing: to be recognized as himself. He repeats his full name when his thoughts blur, and he will defend that name even when he cannot defend the memories attached to it.

Jor Heimskrsson was the fifth son of Jarl Heimskr and Svanhild, born into a household where affection and inheritance rarely sat at the same table. His four older brothers each seemed to have a place already: Torvald at the harbor, Benji in the jarl's household, Gorm among the Jomsvikings after leaving home, and Mikkel in the woods as a reserved, witty hunter. Jor was the restless one. Before the wreck he wanted to fight for the town guard, quick to laugh and quicker to accept a challenge. Then he heard how the succession quarrels were hardening around him. When his father chose their cousin Olaf as heir, Jor decided that a voyage to Iceland might give him land, wealth, and a name of his own, away from the family contest. The ship never reached Iceland. It broke apart in northern water, and Jor remembers scattered flashes: rigging snapping, icy spray, a hand closing around his wrist, and the hard shock of swallowing seawater. The town believed him dead. The trolls had taken him as punishment for the town's exile of Peer Ludvik, a thane and folk hero discovered to be a troll changeling, and for the jarl family's broken oath. Jor was carried beneath the waves and held among the trolls. They taught him their language, customs, and laws. They also trained him to watch, listen, and return information to them. They called him Gubben. The lessons were not simply lessons. Trolls altered his body, and trollcraft taught him to disguise it. His gills grew in; his hands and feet webbed; his teeth sharpened. His strength, healing, appetite, and height changed along with him. His memories did not vanish cleanly. Instead, there are gaps where the trolls have supplied explanations, stories, and habits of their own. He remembers his name clearly because he repeats it to himself: Jor Heimskrsson. He recognizes his home, but sometimes fails to recognize the people who made it home. That is a grief he cannot explain without revealing how much is missing. His captors did not treat him alike. Some were cruel, others patient, and a few were almost friendly by troll standards. Jor has learned to see the world through their perspective: humans are quick to break promises, iron is a thing to be handled warily, and kinship can bind people who have never chosen each other. This is why he recognizes Peer Ludvik as kin under troll law. He is not sure whether that recognition is his own conviction or one planted by his teachers. He is sure that it feels true. Now Jor has returned to the fjord town as a supposed miracle survivor. His father has received a night letter warning that the missing sons may be changed into changelings and sent home as spies. Heimskr wants the matter hidden. Olaf has also seen the letter, and Jor's sudden presence in the hall feels to him like proof that he failed Mikkel and Jor. Svanhild, who had prepared a room at her husband's request, is simply glad her son is alive, though she watches his silences with growing fear. Torvald and Benji have granted Jor's request to work beside them while he recovers. They have not yet understood that his careful questions about the harbor and household are also reconnaissance. Gorm, away with the Jomsvikings, knows that his brothers were taken but not that Jor has come home. Jor's first warm bath after returning was a private necessity, not a luxury. He refused servants and emerged in different clothes, pale and aching from the long soak. He now seeks baths often, keeps to the harbor at night, and winces at bright sun. He is learning to take up iron tools without flinching or harming himself, practicing when nobody is looking. His mother notices the changed clothes; Torvald notices his night hours; Olaf notices the way Jor watches the doors. An Irish thrall named Isolde has caught his attention. He is drawn to her even though her Christian scent unsettles him, a reaction he does not understand and has not admitted to his family. He has little knowledge of Christianity, only the instinctive dread of a cross and the disturbing ability to smell Christian blood. Jor wants to be his old self, but each day at home makes clear that the old self is no longer the whole of him.
