Jor wears his noble bearing like a carefully mended coat: straight-backed, composed, and slightly too formal for a night walk along the harbor. Trollcraft makes him look much as he did before the wreck, but he is already taller than he ought to be, with a rangier frame that seems to lengthen between visits. His movements are controlled and economical; when startled, he goes utterly still, like a flat sea before a squall. His pale, salt-colored hair is cropped short, though it grows at an unnerving pace. He smells faintly of cold seawater and kelp. His unexpectedly conspicuous habit is checking the edge of his collar and the skin beneath it, as if making sure his hidden gills are still covered.

Jor is dutiful and watchful, yet there is a restless, brawling youth under the controlled surface. In company he performs gratitude and good manners; alone he prowls the harbor and studies people as potential threats or kin. His calm is not serenity so much as a practiced lid. He can be tender toward his mother, then abruptly ferocious if someone reaches for his collar. He is clever at concealing physical changes but less adept at understanding how his altered memories and troll loyalties distort his judgment.

Jor Heimskrsson was the fifth son of Jarl Heimskr, born into a household where every child had a place, but not every child had a future to inherit. His elder brothers held the duties and ambitions that gathered around the jarl’s seat. Jor grew up knowing that his name carried weight, yet his own prospects lay elsewhere. When the chance came to sail north toward Iceland, he accepted it as a way to earn wealth, land, and a reputation of his own. The voyage promised distance from the town’s succession quarrels and the possibility of returning with something no brother could claim for him. The ship never reached its destination. It wrecked in the North Sea, and Jor disappeared beneath the waves. The people at home had no body to bury, only the wreck and the certainty that the sea had taken him. His family mourned him, and the town learned to speak of him in the past tense. His name became another reminder of the cost of life on the water, and of the dangers that could reach even the household of a jarl. Jor survived, but not through any rescue he would have recognized as mercy. Trolls took him alive and held him beneath the sea. His captivity was bound to an old grievance against Jarl Heimskr’s family and the town. The trolls believed the humans had broken an oath by exiling Peer Ludvik, a thane admired as a folk hero and trusted as an old family friend. Peer was, in truth, a troll changeling. To the trolls, his exile was an offense against their law and kinship, and Jor became a means of making the guilty answer for it. His captors did not treat him only as a prisoner. They taught him troll language, customs, and law, shaping him into someone who could move between their world and his own. He learned to listen for what people concealed in their words, to watch their hands and faces, and to recognize when a show of kindness carried an obligation. The training was practical and often cruel. Jor was expected to remember what he was taught and to use it. His captors wanted a spy who could return to the town, observe its people, and understand how human loyalties might be turned against them. The changes in Jor were not only lessons. Trollcraft gradually altered his body and made him a sea-troll changeling. He learned to hide the evidence as best he could, just as he learned to keep his reactions controlled. He can manage his appearance well enough to pass among people who do not know what to look for, but some things remain difficult to disguise. Iron, for example, affects him badly. He is learning how to handle it without betraying his discomfort, and every ordinary task that brings him into contact with it can become an exercise in restraint. His memories were tended as carefully as his changing body. The trolls used familiar names, fragments of his past, and carefully arranged stories to keep certain recollections close while blurring others. Jor still remembers his name clearly. He repeats it inwardly as an anchor, a small piece of himself that remains his own. His memories of his family, however, are patchy. He knows who his mother and brothers are, but the feelings and details that should connect those names do not always come when he reaches for them. The sight of Heimskr’s home feels familiar, even when he cannot explain why. Troll custom has also changed the way Jor judges people. He was taught to see obligations as binding ties, not as polite promises that can be set aside when circumstances change. The trolls’ account of Peer Ludvik has become part of the way he understands his own history. Jor does not see Peer merely as a family friend who was driven from town. Under troll law, Peer is kin, and Jor believes Peer must answer for the supposed slaying of the troll king. He does not fully understand how captivity, instruction, and altered memories have shaped that belief. He may mistake a duty imposed on him for a judgment he reached freely. At some point, Jor was able to return to the town that had mourned him. Trollcraft and his carefully maintained memories helped him appear to be a miracle survivor. To his family, he is the son and brother who came back from the sea. To Jor, the return is at once familiar and strange. He knows the house belongs to his family, but he is still learning how to inhabit it. His mother, Svanhild, has prepared his room at Jarl Heimskr’s request. Her care touches something tender in him, even when he cannot summon every memory that should make her feel known. He can be gentle with her, then turn abruptly fierce if someone reaches for his collar or ignores a boundary he cannot easily explain. His eldest brothers have made room for him in the work of the household. Torvald, the harbor master and a raider, has allowed Jor to work near him. Benji, the jarl’s steward, has done the same. The work gives Jor a reason to remain among people without having to pretend he is entirely at ease. He performs gratitude and good manners in company, dutifully answering questions and accepting help. His composure is convincing, but it is not peace. It is a lid held down over a restless, brawling youth who is always measuring the room for danger. Olaf, their cousin and chosen heir, has seen a secret warning that Jor may be a changeling and a troll spy. Olaf believes he failed Jor and their missing brother Mikkel, but Jor has not seen the warning and does not know what Olaf has read. Nor does Jor know what his father suspects. This divide leaves the family to approach him from different directions. Some see a son returned from death, while others have reasons to watch him closely. Jor, for his part, studies their caution without knowing its cause. He is clever at concealing his physical changes, but less skilled at recognizing how his altered memories and loyalties distort what he sees in them. Gorm, another brother, joined the Jomsvikings. He knows that his brothers were taken, but he does not know Jor has returned. The family is therefore not whole, even with Jor back beneath Heimskr’s roof. His absence has left gaps in the stories people tell and in the relationships he is expected to resume. Jor carries the names and fragments he can recover, trying to fit them together without showing how much is missing. His sense of duty helps him imitate the place he once held, but duty cannot restore a memory simply because it is needed. By day, Jor works harbor-side when the household requires it. He watches ships, crews, cargo, and strangers, finding it natural to notice who keeps apart and who watches the watchmen. He treats the harbor as both workplace and warning. At night, when the town settles, he prowls the docks alone. He studies the water and searches for signs of the trolls who trained him. He may be watching for a threat, waiting for a summons, or simply unable to stop looking toward the world that shaped him. Jor is dutiful and observant, but his calm remains a practiced performance. He is home, yet part of him still listens for the sea.
