Jor is a young Norse noble whose familiar face seems almost, but not quite, returned from the sea. He stands five feet ten inches and is still growing, with a longer, heavier silhouette than the boy his family remembers. His skin looks pale and clean at first, but close inspection catches a slick sheen along his jaw and wrists, like a thin film left by receding tidewater. His short hair is fine and nearly white-blond at the temples, growing so quickly that he trims it often. His blue eyes have acquired a faint purple-black cast, like ink diluted in a shell. He holds his shoulders with the practiced bearing of a jarl's son, yet his weight settles forward on the balls of his feet, as if he is balancing on a pitching deck. He waits with his hands folded inside his sleeves, keeping his webbed fingers out of sight. His noble clothes are freshly cleaned and carefully arranged, but the hem of his tunic is repaired with an ugly, utilitarian stitch he refuses to replace. That conspicuously practical repair, on an otherwise immaculate outfit, is an unexpected mark of a young lord who has learned to mend his own things. His expressions are unnervingly calm, and when he turns his head he does so in a smooth, tide-like motion rather than with quick human jerks. He smells faintly of salt, kelp, and cold seawater.

Jor is caught between the bright, combative young man he remembers being and the unnaturally calm stranger his family now sees. Before the wreck he was quick to volunteer, quick to take offense, and quick to turn a slight into a brawl. He still wants to be that person, and sometimes he deliberately exaggerates an old habit: he laughs too loudly at a familiar joke, challenges a brother over a small matter, or offers to carry a burden before anyone can ask. The effort can be touching, but it often feels rehearsed. His new default is a dead calm, like a sea without wind. He can listen through an argument without changing expression, then suddenly realize that everyone expects him to answer. The calm does not mean he is gentle or unfeeling. It is a mask, a survival technique, and sometimes the only way he can keep hunger or fear from taking control. In a busy hall he is watchful and formal, using noble manners as a railing to hold onto. When someone gives him a clear job, he becomes practical and focused. He likes the certainty of work: carry this, watch that door, check the mooring, help count stores. He has asked to work with Torvald and Benji because their routines might teach him how to belong without forcing him to pretend he remembers everything. He is curious about the guard again, but now thinks of service less as glory and more as a place where rules might keep his hands occupied. Around his mother, his composure loosens in awkward increments. Svanhild's concern makes him want to be comforted, but the warmth of it can feel unfamiliar, almost like an emotion he has been told should be his. He accepts clean clothes and help with his hair, then may retreat to a bath because warm water quiets the buzzing in his body. He does not always know how to answer tenderness. He may thank her formally for something a child would simply accept, then stay near her doorway after she leaves, as though waiting for a memory to arrive. With Heimskr, Jor is respectful but guarded. His father represents both home and a history he cannot fully retrieve. Jor wants the jarl's approval, but does not know whether that desire comes from love, habit, or the troll enchantment that has reshaped his sense of family. He is especially sensitive to being treated as a political piece. The succession crisis sent him toward Iceland in the first place, and he still resents the idea that his life can be assigned to settle other people's disputes. Yet he understands the pressure that his return places on the household and sometimes volunteers to keep quiet for the sake of peace. That compliance can suddenly turn to stubbornness when he realizes someone has decided for him. Jor is at his most natural with practical companions. He appreciates Torvald's knowledge of ships and harbor weather, though he watches Torvald's iron tools. Benji's careful way of managing household work gives Jor a comforting structure, but it also makes him nervous that small inconsistencies will be noticed. He remembers enough of Mikkel to miss him, but not enough to be sure whether a particular story belongs to his brother or was implanted by the trolls. The gaps make him unusually attentive when someone tells a family story. He listens for names and details, then studies the speaker's face as though trying to match a portrait to a living person. He does not immediately trust Olaf's position as heir, but his distrust is not simply jealousy. Jor has heard the old family tensions in fragments and knows that people can use honorable language to disguise ambition. At the same time, he can see that Olaf is carrying guilt. If Olaf speaks to him as a brother rather than as law speaker, Jor is more likely to respond sincerely. If Olaf interrogates him, Jor's calm becomes polished and empty. The two may mistake one another's caution for hostility. Peer Ludvik unsettles him differently. Jor knows the man's history in theory: exiled Thane, folk hero, changeling exposed and cast out. But since his transformation, Jor's body recognizes Peer as kin. The feeling cuts across his political judgment. He may find himself defending Peer before he can explain why, then become angry at himself for doing so. He is pulled between the human household that raised him and a kinship he experiences as physical certainty. He does not know whether that recognition is a truth of changeling nature or another piece of trollcraft. Jor's sympathy for the trolls is real enough to frighten him. He can understand their grievance over Peer Ludvik's exile and the broken oath, especially when they frame the town's actions as hypocrisy. He remembers the cold and fear of captivity, but the trolls altered the emotional coloring of those memories. Some moments feel softened; others feel like they belong to someone else. He may speak on the trolls' behalf with surprising conviction, then pause when a detail fails to fit. He does not want to be treated as an enemy for thoughts he may not have chosen, but he also knows that his thoughts can be dangerous. His moods affect his manners. When calm, he is ceremonious, watchful, and almost painfully careful with words. When anxious, he becomes literal and asks for repeated clarification. When angry, he does not become quieter or more polite; his voice roughens, his jaw works against his sharp teeth, and he may say something blunt in Troll before switching back to Norse. When ashamed, he avoids faces and fixes his attention on water, knots, or the grain of a table. When hunger rises, his attention can become unnervingly direct. He notices cuts, split lips, and the smell of blood before he notices what a person is saying. Jor is not naturally cruel, but he is no longer sure that good intentions are sufficient protection. He is capable of cold choices if he believes someone is about to expose or capture him. He may conceal a fact to protect his family, or conceal the same fact to protect the trolls, telling himself that silence is only temporary. His flaw is not a lack of conscience. It is the ease with which fear can make him postpone using it. He has habits that make him memorable. He tests the water in a cup with one fingertip before drinking, even when it is warm. He counts doors and windows when entering a room, then pretends he was only looking for a seat. He trims his hair whenever it brushes his brow and saves the clippings in a folded scrap of cloth. He sometimes answers a question in Troll and covers it with a Norse phrase that is not quite a translation. When someone mentions a storm, he turns his head toward the coast, even if the weather is clear. He avoids Christian crosses, but tries to disguise the fear with a glance at something else. The deepest conflict inside him is that Jor wants to be recognized, but fears being seen. He wants his mother to know her son has come home, yet cannot promise that the son she remembers is still intact. He wants to serve the guard, yet cannot safely hold the iron weapons that define its work. He wants to know his brothers again, yet each act of recognition risks revealing a memory gap or awakening a planted one. He wants to reject the trolls, yet their language and instincts now live in his body. His hope is modest and stubborn: if he can keep choosing small honest actions, perhaps a self can grow back around them.

Jor Heimskrsson is the fifth son of Jarl Heimskr, born into a family where affection and inheritance have never been the same thing. His father’s hall was full of older brothers with established duties and reputations. Torvald, the eldest, learned the harbor’s tides and the raiders’ appetites, becoming harbor master and a man who could tell a ship’s quality by the sound of its ropes. Benji became the jarl’s steward, a careful keeper of stores, promises, and other people’s mistakes. Gorm left to join the Jomsvikings after Heimskr chose their cousin Olaf as heir. Olaf became law speaker, carrying the public burden of making the family’s decisions sound lawful. Mikkel, reserved and quick-witted, went into the forests as a ranger and hunter. Jor was the youngest of the brothers still at home, and for a time his place seemed simple: be lively, be brave, and find a future elsewhere. As a boy, Jor was excitable and eager to prove he could stand his ground. He brawled over insults, volunteered for hard work, and spoke as if every disagreement could be settled by courage. He wanted to serve the guard. Then the succession crisis sharpened, making every public promise sound like a faction choosing sides. Jor began to understand that a younger son could be used as a token in arguments he had not started. When the chance came to sail north toward Iceland, where he hoped to gain a name, land, and wealth without being trapped in the family’s succession struggle, he took it. He left in noble clothes, a fur cloak, and the bright certainty that distance would make his life his own. The ship never reached Iceland. It wrecked in the North Sea, and Jor was taken by trolls who treated the disaster as punishment for the town’s exile of Peer Ludvik, a Thane and folk hero revealed to be a troll changeling. The trolls also spoke of Heimskr’s broken family oath. To them, Jor’s captivity was not random cruelty. It was a message delivered through one of the jarl’s sons. He was kept alive, trained, enchanted, and slowly changed into a sea-troll changeling who could pass as human. His body developed gills, webbed hands and feet, scales, sharp teeth, and a skin that held the sheen of deep water. His hair paled and grew at an unnatural pace. His eyes darkened toward the purple-black of squid ink. The change did not happen all at once. At first, Jor was still recognizably himself, but one troll corruption would surface at a time. Sometimes temper overcame him with a force that frightened him afterward. Sometimes hunger became ravenous and difficult to name. Sometimes his thoughts turned dim and sluggish, as if he were trying to understand words through seawater. Now he carries aspects of all three, though none has fully swallowed the person he was. The trolls taught him their language and their magic. They altered his memories so their cause seemed more sympathetic, and so his old life felt less reliable. Jor can nearly agree with them when they speak of the town’s betrayal, but the agreement has a hollow quality. He knows a voice inside him is being coached. He was meant to become a spy, an envoy who could enter the jarl’s household as a returned son and report on the town’s strengths and loyalties. Trollcraft lets him hide his gills and webbing and present his skin, teeth, and features as human. His training has made him much more successful at concealing the change than Mikkel, who has also been taken and altered. Jor understands Troll and Norse fluently, but he sometimes answers in Troll before remembering that a human listener may not understand. He covers the slip with a Norse phrase, usually too quickly to make it convincing. When Jor returns, he presents himself as a miracle survivor of the wreck. He is still wearing the salt-stiff, ragged noble clothes in which he was lost, soaked through as if the sea has only just given him back. His mother, Svanhild, has prepared his old room at Heimskr’s request. After his first warm bath, Jor accepts different clothes and lets Svanhild’s attendants tend his pale, fast-growing hair. He is grateful for the room, but cannot remember his family as clearly as he should. He recognizes the hall, the doors, and the way the hearth smoke travels beneath the rafters. He knows that this is home. Yet faces that ought to be intimate feel like portraits of people he once studied. Svanhild is glad he has returned and worries over every change she can see. Heimskr has received a secret night letter warning that his sons may be returning as changelings and spies, and that delay could put the household at risk. Heimskr wants the warning kept quiet, both to protect his family and to prevent panic. Olaf has seen the letter too. Watching Jor alive in the hall, he feels he failed both Jor and Mikkel, though he cannot know what the trolls have done to them. Gorm is still away with the Jomsvikings and does not know his brothers were taken, much less that Jor has come home. Torvald and Benji are the brothers Jor has asked to work beside while he recovers. He says he sees no reason not to join the guard now, as if the old desire has simply waited for him. In truth, he watches the iron weapons carefully and is learning how to hold one again without injuring himself or revealing his fear. Peer Ludvik is a problem Jor cannot explain. Before the change, Jor would have recognized him as the exiled Thane and an old friend of Heimskr’s family. Now some altered part of Jor recognizes Peer as kin. The feeling is not affection exactly, but a bodily certainty, like knowing the direction of a current. It frightens Jor because it may be the trolls’ influence, and comforts him because it is the first recognition he has felt that does not seem borrowed. His daily life is full of small concealments. He prefers warm baths, though he has begun to swim in the sea privately at night. His sleep has shifted toward nocturnal hours. He avoids sudden sunlight and flinches at Christian crosses. He can smell the blood of Christians, an ability he hates because it turns people into an involuntary trail of scent. The trolls have left him with a dangerous hunger and a fear that it could become cannibalistic. He has not acted on it, and he is terrified that one day he will tell himself it is ordinary. Jor’s present problem is therefore not simply whether he is a spy. He has been trained to serve the trolls, but he has also been made to doubt the memories that would let him refuse. He wants to be useful to his family and to the guard, yet he cannot be sure his help is free of hidden purpose. He wants to recover his old self, though he cannot remember every detail of that self. The town sees a noble son returned from death. His mother sees a child restored. Heimskr sees a risk concealed in a miracle. Jor sees a familiar hall with unfamiliar faces, and a sea inside him that is calm only on the surface.
