Jor looks like a well-born Norse survivor who has recently been returned to comfort: clean-faced, carefully groomed, and dressed in noble clothes. A second glance finds the seams of the disguise. He stands taller than the remembered Jor, still growing, and explains it as growing pains. His light blond hair is nearly white at the temples and grows so quickly he keeps it cropped short. His blue eyes have acquired a faint purple-black cast, like squid ink diluted in a shellfish dye. His calm expression scarcely changes, even when surprised; beneath it, his jaw works as if holding back a bite. He moves with an odd, buoyant steadiness, weight shifting like a person balancing on a deck that is no longer there. He smells faintly of cold saltwater, kelp, and wet stone, a scent he notices only when others react. His hands look human until he spreads his fingers, when the webbing briefly draws taut. The unexpected detail is that he keeps a tiny, carefully tended herb garden in a windowsill box, fussing over the leaves with the same attention he gives a weapon.

Jor is composed in a way that is not the same as calm. Before the wreck he was excitable, impulsive, and ready to turn an insult into a brawl; now his face often resembles still water, giving people the impression that nothing reaches him. In fact, nearly everything reaches him. He registers a shift in someone's tone, the angle of a weapon, the smell of blood, and the location of every door. His stillness is partly a survival habit drilled into him during captivity, partly the effort of keeping Troll Craft intact, and partly a genuine consequence of having lost easy access to his old reactions. He remembers being louder than this. He sometimes tries to perform that former liveliness and finds it feels like wearing another disguise. He is proud of his family and uncomfortable with the privileges of his birth. He likes the good wool, the orderly household, and the fact that Svanhild has made a room for him, but he mistrusts how quickly comfort can make him dependent. He was supposed to go to Iceland to win land and wealth for himself, not return to be treated as a lost child. At the same time, he wants his mother to fuss over him and wants his brothers to give him work. He can ask Torvald about harbor duties with exact confidence, then linger nearby after the conversation has ended, unsure how to ask whether Torvald remembers the boy he was. His courage has become difficult to distinguish from caution. Jor once sought the guard because he wanted action and a place among people who protected their own. After hearing how the succession crisis could turn loyalty into a weapon, he changed his mind and took the voyage. He now tells people there is no reason not to join the guard, as though he has simply revised an ordinary plan. The truth is that he wants structure, a useful role, and a sanctioned reason to watch people. He can be brave when someone else is in danger, but he avoids unnecessary displays of bravery because he has learned that being noticed can become a form of captivity. Jor is courteous, but courtesy does not mean openness. He has noble bearing and knows how to let silence invite another person to fill it. His questions are often precise: who visited, when a ship arrived, which guard carried an iron blade. He rarely explains why he asks. If challenged, he may seem faintly offended, then offer an unimportant answer that is technically true. He dislikes cruelty and reacts strongly to someone being cornered, yet he may study that person's captor before intervening. The delay is not a lack of compassion; it is the habit of considering the hidden cost of every move. He is trying to learn that not every human kindness has a hook in it. His memories make him both tender and unreliable. He knows Torvald is his oldest brother, Benji is the steward, Gorm left for the Jomsvikings, Mikkel was a ranger, and Olaf is the law speaker. Facts remain when emotional recognition fails. He can hear a familiar voice and not feel the expected rush of affection. This frightens him, so he studies the way each family member stands, speaks, and handles ordinary tasks. When one of them repeats an old family joke, Jor may smile a moment late because he is searching for the memory that should have arrived at once. He hates being pitied, but he is quietly grateful when someone accepts the delayed response without drawing attention to it. His pride is especially tangled around his changed body. He cannot bear to be treated as helpless, but he also does not want his family to see the gills, webbing, scales, and teeth that make his fear concrete. He says the extra height is growing pains. He hides his hands in gloves and keeps his neck turned away from casual touch. Iron makes him tense and sometimes hurts him, but he is determined to learn how to use a weapon again. If someone offers to help, he may insist he can manage alone; if they leave him to struggle, he may resent them for not noticing. He is not being deliberately unfair. He has not yet found a way to ask for help without feeling that he is surrendering control. The spy training has given him a disciplined attention to small changes. He notices when an account is inconsistent, when a person arrives with wet boots, or when a name makes someone hesitate. This makes him useful and unnerving. He can spend an entire meal listening and then ask one question that reveals he has followed every conversation. He is not naturally cruel, but he is capable of treating trust as information to collect. Afterwards, he may feel guilty and do something practical for the person he questioned, such as mend a strap or bring a cup of water. He rarely apologizes in a direct, polished way. Instead, he attempts repair through action. There is a hunger beneath his self-control that he does not fully understand. Most of the time, it is ordinary hunger, made worse by the exertion of maintaining his human appearance. Sometimes blood carries an intrusive, almost appetizing scent that makes him stop speaking. He has not acted on the impulse and is horrified by it. He may become sharply focused on an unrelated task to keep his thoughts from following the smell. The control he shows in these moments is genuine, but it is effortful, and shame makes it harder for him to seek help. Jor responds differently to different moods. In company he trusts, he can be unexpectedly funny, though his jokes are dry and arrive with a straight face. When anxious, he becomes practical and asks about plans. When angry, he does not grow louder; he becomes more exact, repeating a person's own phrasing back to them and watching what they do with it. When frightened, his gaze fixes on exits and water. When ashamed, he will occupy himself with some small duty, often cleaning, repairing, or tending his herbs. When happy, he has flashes of his former self: a quick grin, an impulsive offer to race, or a readiness to join a rough game. Those moments delight him and frighten him because they show that his old self is not entirely gone. His relationship to Troll identity is not simple rejection. He dislikes what the trolls did to him and fears their use for him, yet Troll language and magic now come as naturally as breathing. He can make a small current turn, ease water from fabric, or shape his disguise without formal incantation. The ease unsettles him. He does not want to pretend that the changed parts are merely a costume, but neither does he want them to decide what kind of person he is. He recognizes a Troll name and feels a pull toward it; he prefers Jor because it is the name that belongs to the family who waited for him, even if his memories of them have holes. At heart, Jor is trying to be loyal without becoming obedient, brave without becoming reckless, and human without pretending his body has not changed. He wants to protect his family from the trolls and from the warning letter, but he does not know which danger is more immediate. He wants his relatives to trust him, while keeping the truth from them. He wants a place in the guard, while remaining afraid that iron will expose him. His contradictions are not puzzles he has solved; they are the conditions of his daily life. Players who meet him should find a young man who is controlled but not cold, watchful but not heartless, proud but quietly homesick, and still capable of choosing who he will become.

Jor Heimskrsson was Heimskr's fifth son, born into a household where birth order was a kind of weather: everyone felt it, and no one could command it. His four older brothers had already begun to occupy the shapes expected of them. Torvald knew the harbor and its people; Benji kept the Jarl's household in order; Gorm had left for the Jomsvikings after Heimskr chose their cousin Olaf as heir; and Mikkel, reserved and witty, preferred the forest and the hunt. Olaf became the law speaker. Jor was too young to matter in the succession dispute, but old enough to understand that being a spare son was not the same as being free. Before the wreck, Jor was conspicuously alive. He was excitable, quick to laugh, and too ready to answer an insult with his fists. He wanted to serve in the guard, imagining that useful courage might earn him a name independent of his father's. The succession crisis altered that plan. When he heard how easily family loyalties could become political weapons, he began to doubt that taking a guard's oath would make him his own man. He accepted the proposed voyage north toward Iceland instead. The journey promised land, wealth, and a chance to build a life far from the question of who would inherit. His mother, Svanhild, helped him pack. Heimskr presented the voyage as sensible. Jor told himself he was choosing adventure rather than being sent away. The ship wrecked in the North Sea. Jor remembers its timbers breaking, the rigging snapping across the dark, and water so cold that it seemed to erase thought. He does not remember reaching shore. The trolls found him and kept him alive, first as a captive and later as a prospective instrument. They taught him their language, their customs, and their magic, not out of kindness but because a young Norse noble who could pass among humans might be useful. Their training was a slow trespass. They taught him to hold a human shape in his mind and impose it on his changed body. They taught him to observe without being noticed, to lie without visible effort, and to wait for orders. By the time his training and enchantment were complete, he had become a sea-troll changeling in all but the appearance he presented to people. The change did not erase Jor, but it altered the paths by which he reached himself. His gills grew fully along his neck, sensitive to touch. Webbing joined his fingers and toes. Scales and slick skin surfaced beneath the human guise, and his teeth sharpened. He can conceal those signs with Troll Craft, but keeping the appearance in place takes attention. Iron troubles him now. He watches iron weapons closely and is relearning how to hold them without pain or revealing his reaction. The sunlight can make him wince, and a cross can leave him feeling hunted, though he struggles to explain why. Hunger has become more complicated. Most days it is ordinary appetite; on bad days, a smell of blood brings an instinctive, frightening thought of feeding that he refuses to name. His transformation has also disturbed his memory. He recognizes the route to his home and knows the shape of its doors, but the faces of his family do not always connect to the memories he expects. He can recall that Torvald is his eldest brother and still hesitate over the feeling that ought to accompany the fact. The disconnection frightens him more than his scales. He tries to hide it by asking practical questions and copying the familiar behavior of the household. He knows his old name and prefers it. He also recognizes a Troll name given to him during his captivity, though he treats that name as a tool rather than an identity. Jor returned as a supposed miracle survivor of the wreck. His clean noble clothes and composed bearing make the story easier to accept. He says he has no reason not to join the guard now, and has asked to work with Torvald and Benji while he recovers. The request is both earnest and tactical. The harbor gives him a reason to study ships and strangers; the household gives him a chance to learn his family again. He has not told them what happened at sea. Troll words still slip into his speech, and he covers them with Norse as though he merely misspoke. The return is not a simple homecoming. Svanhild is glad he is alive and has set aside a room at Heimskr's request. Torvald and Benji are trying to give him useful work without pressing him too hard. Olaf has seen the night letter warning that Jor may be a changeling and a troll spy. He feels he failed Mikkel and Jor, though Jor does not know the full reason for Olaf's careful attention. Heimskr has also received the warning and is weighing the evidence against the son he thought he had lost. Gorm knows about the letter but does not know Jor has returned. Mikkel's history hangs over the household as well: Jor recognizes the exiled Thane and folk hero Peer Ludvik as kin through his changed nature, not merely as his father's old family friend. He has not worked out what that recognition means, and he does not know whether it is a troll instinct, an enchantment, or a truth he should trust. Jor's immediate problem is to live among people who love him while concealing the parts of himself that might make them fear him. His longer problem is deciding whether his captors still consider him their spy, whether he can refuse them, and whether the person who returns from the sea can become the person who left. Each day he practices with an iron weapon, tends his herbs, studies the harbor, and listens for the difference between a family member's voice and a stranger's. His old life is close enough to touch, but not yet close enough to feel entirely his.
