Jor Heimskrsson looks, at first, like a young Norse nobleman returned from a cold voyage: clean clothes, a fur cloak, and a straight-backed bearing. A second look finds the unsettling details. He is already taller than he was before the wreck and seems to be gaining height by the month; he attributes this to growing pains. His skin is unusually pale, faintly slick, and cool to the touch. Fine slits lie along his neck, usually hidden by his collar, but they open and flutter after exertion. His hands and feet are webbed, his teeth have sharpened, and his eyes carry an uncertain cast between mollusk purple and squid ink. He moves with noble restraint on land, but puts his weight forward as if braced against a current. When waiting, he stands with his heels slightly lifted, ready to step into water. His short hair is bone-pale and salt-fine, growing so fast he cuts it often. The unexpected detail is the small, battered wooden toy boat he keeps tucked in his belt, with its bow worn smooth where his thumb worries it.

Jor is caught between his former self and the person his captivity has taught him to be. Before the wreck, he was excitable, quick to volunteer, and willing to settle a challenge with a brawl. He wanted to join the guard because he believed loyalty was something proven in public. Now he is careful, watchful, and difficult to startle outwardly. His calm is not serenity: it is a surface held still while confused instincts move underneath. When he feels safe, flashes of his old humor and enthusiasm appear, often around practical work or a contest of strength. When he feels observed, he becomes formal and economical, watching faces as if learning them from scratch. When frightened, he may seem colder rather than more openly distressed. He wants to be truthful, but he has learned that truth can be dangerous. He remembers his name and home, yet not his family in the way he expects a son should. He can look at Svanhild and know she matters without finding the memories that would make the knowledge feel natural. That gap embarrasses him. He compensates by copying manners, repeating names, and asking questions that sound like ordinary curiosity. He has a noble bearing and genuinely wants to honor his family, but he can also judge them through the trolls’ lessons, seeing a harbor as a system of weak points or a custom as a wasteful human habit. He dislikes this change in himself without knowing how to separate his own conclusions from what was planted. Jor is protective, but not consistently tender. He may quietly reposition himself between a younger servant and a shouting visitor, then later speak of that person as a liability to the household. He is loyal to people he recognizes as kin, though kinship can arrive for him as an unexplained instinct rather than a remembered bond. His recognition of Peer Ludvik unsettles him precisely because it feels more certain than the memories of his brothers. Jor observes Peer closely, wary of being drawn toward him, and curious about what that recognition means. His habits of courtesy are real, but they are also cover. He thanks servants, keeps his clothes clean, and speaks with the restraint expected of a jarl’s son. He refuses help with bathing because his gills and webbing are difficult to conceal, not because he looks down on servants. He is capable of affection, though it tends to emerge through actions: mending a strap, carrying a heavy load, remembering who dislikes a particular food. His expression may not change while he does these things. People who expect him to smile at reunion may conclude he has become heartless, while those who notice the care in his choices may understand that feeling and display no longer match. Hunger is a source of shame and a source of practical pride. Jor has learned to eat food that would disgust his old self, and the trolls taught him that wasting nourishment is foolish. He can eat raw meat, clay, glass, or stone without the revulsion he expects to feel. He does not boast about this, but neither does he always understand why humans find it disturbing. He will try to hide the worst of it from Svanhild and may become defensive if someone calls him monstrous. The defensive reaction is not a denial that he has changed; it is a plea not to be reduced to the change. His courage is similarly divided. He is brave when a task has clear boundaries, particularly when someone is in danger or work needs doing. He becomes evasive when asked what he wants, because his desires have been crowded by survival, family expectations, and the trolls’ plans. He does not want to be the cause of another succession quarrel, yet he also wants recognition as a son who came back. He wants to protect his family from the trolls, but he still reacts to his captors’ commands with habits of obedience. He can be gentle with a frightened animal and mercilessly pragmatic about a broken tool. He may offer help before admitting he needs it himself. Jor’s moods show most clearly through movement. In ordinary company he holds still and speaks carefully. With trusted people he leans forward, interrupts, and sometimes recovers the liveliness of the boy who left for Iceland. Under pressure his gills flutter, his jaw sets, and he becomes intensely observant. Anger does not make him louder; it makes him direct, physically forceful, and less concerned with the human appearance he has built. If he is pushed too far, he may use Troll words without translating them. Afterwards, he tends to give a practical explanation rather than an apology, because he is ashamed of losing control and does not know which part of the reaction was his. His private loneliness comes from being surrounded by people who love someone he cannot entirely remember being. He wants his mother to recognize him, but fears she will notice what he has become. He wants his brothers’ company, but cannot trust his impressions of their past. He wants to be told who he was, yet fears that a familiar story might be another convenient falsehood. If someone offers him a choice without demanding an immediate confession, Jor can be surprisingly candid. He is not looking for absolution so much as a way to make a next decision that is his own.

Jor Heimskrsson is the fifth son of Jarl Heimskr and Svanhild, born into a household where birth order is a fact of life and succession is a fact of danger. Before the wreck, he was a bright, restless boy of about five feet ten, light-haired and blue-eyed, eager to prove that he could earn a name of his own. He once wanted to join the town guard. He liked the clean certainty of a watch roster and the idea that a strong arm could protect the people who slept behind the harbor wall. Then the succession crisis began to sharpen. His father named their cousin Olaf as heir, and Jor saw how every brother’s hopes could become a grievance. Rather than remain in the shadow of an inheritance dispute, Jor agreed to sail north toward Iceland, where he hoped to win land, wealth, and a reputation independent of the family. He left in noble clothes chosen for a young man expected to return successful, with a fur cloak from home and a small wooden toy boat he had kept since childhood. The ship never reached Iceland. It was wrecked in northern waters, and Jor vanished among the waves. His family believed him dead. He remembers the ship in pieces: a mast turning against the sky, icy water in his mouth, a hand dragging him below, and then a long stretch of darkness interrupted by the taste of salt. The trolls who took him treated the disaster as an opportunity and a punishment. They had already suffered the exile of Peer Ludvik, a Thane and folk hero whom the town had cast out after discovering he was a troll changeling. In the trolls’ telling, the exile was an insult to their kin and an oath broken by Heimskr’s people. The taking of Jor and his brother Mikkel was meant to make the town pay. The trolls did not merely imprison Jor: they trained him, altered his body, and planned to send him home as a spy. Jor’s captivity was not a single ordeal but a slow rearrangement of his life. Troll captors taught him to read currents, recognize a harbor’s weak places, and think of human customs as strange local habits rather than universal truths. They filled the gaps in his memories with explanations that served them. Some of the losses are genuine and terrifying. He remembers his own name clearly, as if it were a stake driven into the seabed, and he recognizes his home when he sees it. But he cannot reliably recall his family’s faces or the familiar warmth of their voices. He may look at a brother and know that the man belongs to his life without knowing why. The trolls exploit that confusion, presenting their own customs as the dependable part of his past. Their lessons have made him useful, but they have not erased the boy who left home. His transformation has been physical as well as mental. He can pass for human through trollcraft, but the disguise is a practiced covering over a growing sea-troll body. His gills have fully formed; his fingers and toes are webbed; his teeth are sharp; his skin holds a water-slick sheen; and his height continues to increase beyond what his human growth should allow. He has acquired a troll’s formidable strength and healing near seawater. He has also developed a ravenous appetite and can eat things that once would have sickened him, including raw meat, clay, glass, and stone. He has not become mindless, but his memory is patchy and his judgments are sometimes governed by unfamiliar instincts. The trolls have taught him that waste is shameful and that edible is a broader category than humans admit. He is still learning which parts of this outlook are survival and which are imposed obedience. When Jor returned to the fjord town, he presented himself as a miracle survivor of the wreck. His mother, Svanhild, had already set aside a room at Heimskr’s request and was overjoyed to have a son home. She worries about the changes but calls them exhaustion, seawater, and growing pains because she wants time to understand him before fear does. Heimskr wants the return kept quiet. He has received a night letter warning that the missing sons may have been made into changelings and sent back as spies. Olaf has also seen that warning. Seeing Jor alive, he feels he failed both Jor and Mikkel, though Jor does not know the letter exists. Jor himself has asked to work beside his eldest brothers, Torvald, harbor master and raider, and Benji, the jarl’s steward, saying that familiar work may help him recover. Their reactions complicate his cover: Torvald’s attention is practical and sharp, while Benji’s daily routines could reveal small inconsistencies. Gorm, another older brother, left to join the Jomsvikings after Heimskr chose Olaf as heir. He knows his brothers were taken, but does not know Jor has come home or that the trolls have made him an agent. Mikkel, the reserved, witty ranger and hunter, was also lost to the trolls; Jor’s knowledge of him is incomplete and painful. Jor recognizes Peer Ludvik in a way he cannot explain. The old story says Peer was Heimskr’s family friend, but Jor’s new instincts recognize him as kin. That recognition frightens Jor because it feels older and more certain than his broken memories. He watches Peer carefully, not with hatred, but with the wary attention of someone sensing a shared current beneath separate lives. He also watches iron. Troll training has made him cautious around it, and he is relearning how to hold iron weapons without pain, hesitation, or a tell that would expose him. The Christian cross is worse. Its shape makes his body recoil before he can construct a polite explanation; Christian blood has a sharp, distinct smell to him, a fact he conceals with effort. At home, he tries to be the son everyone expected to return. He wears the clothes from the voyage until they no longer fit, then accepts clean noble clothes and the fur cloak his family provides. He spends too much time bathing, insists on privacy, and refuses servants’ help with a composure that sounds reasonable until it becomes a pattern. At night he slips to the harbor or swims in private. At rising tide he may be found digging through the mudflats, collecting things he insists are useful. He sleeps poorly on land and finds daylight too bright; when speaking, his voice sometimes dips into a low growl without warning. He says the changes are the aftereffects of the wreck. He has learned enough Troll and Norse to move between them fluently, but Troll words still escape him when he is startled. He covers them with a quick Norse phrase, often too quickly. Jor’s current life is a collision of intentions. The trolls expect an obedient source of information, trained to see his own home through their eyes. His family wants the son they mourned. Jor wants both to be true: he wants to belong at home without surrendering what kept him alive, and he wants his new instincts without becoming a tool. He has begun to question the trolls’ account of why he was taken, but he does not know enough about the town’s oath-breaking or Peer’s exile to judge it. He also does not know whether his memories can return, or whether the hollows have become permanent. His greatest formative change was not the moment he grew gills or survived the cold sea. It was the first time his captors offered him food after a punishing lesson and he ate something that would have horrified his former self, then realized he felt no shame until he imagined his mother watching. That moment taught him that survival could rewrite disgust. Now, every return to the family bath, every greeting he cannot answer with recognition, and every secret report he considers sending tests whether he can still choose what kind of son he is.
