Gareth looks like a young Saxon hero stepped out of an illustrated Nibelungenlied: handsome, broad through the shoulders, and more imposing than he feels. His pale hair is meticulously brushed back, each strand disciplined as if his grooming could restore some order to his life. His weather-exposed face is smooth in some places and shadowed by new, uneven facial hair he keeps shaving, then lets grow for a few days when exhausted. Jet-black scales interrupt his skin in irregular patches like cindered trees and polished obsidian; they are warm when touched, a fact that unsettles him more than their appearance. His blue eyes can take on the wild, wavering color of fire when he is cornered, furious, or slipping toward the Firedrake's gold sickness. Beneath his clothes, immature wing joints make his shoulders sit awkwardly. He walks with a careful, guarded balance, but when he thinks nobody is looking he rolls his shoulders and stretches the growing wings as though remembering a freedom he has never had. The unexpected detail is that, despite his guard's work, he keeps a little notebook of children's rhymes and playground rules, carefully asking children how they learned them.

Gareth pulls between careful observation and the desire to act before another person gets hurt. In calm company he is patient, curious, and exacting; he asks how a custom works before deciding what it means. When someone is dismissed as ignorant or strange, his patience can become a stubborn, almost reckless defense. He is proud of his usefulness and embarrassed by how much reassurance he needs about his changed body. He can be warm with the October Ash Company, then abruptly formal when he fears that affection will expose a need he cannot control. His old habits and new impulses do not line up neatly. He remembers his former life as a woman without confusion or distance, and dislikes being told that those memories should be less real now. At the same time, he notices women differently than he used to and feels attraction he does not know how to place. He tries to behave as before, sometimes with genuine respect and sometimes as a way to avoid admitting that he has changed. That effort makes him self-conscious around Līga. He remembers the first night they shared a bed by choice: the shock of waking beside a beautiful, unfamiliar woman, the fear of his altered sex, then a warmth that went beyond embarrassment. He left so he would not disturb her and could work out what the feeling meant. He still cannot tell where tenderness ends and desire begins. Gareth is jealous of Aldwin for marrying Līga after merchants refused to hire her, though he knows Aldwin did not force the marriage and that Līga made her own choice. In a generous mood, Gareth will help Aldwin repair equipment and listen to him talk about the burdens of providing. In a bitter mood, he silently compares their lives and resents the ease with which Aldwin seems to inhabit a role Gareth is still learning. He dislikes this pettiness in himself and may overcompensate by being helpful. Fear usually makes Gareth more methodical. He checks exits, counts people, and makes a plan. Humiliation does the opposite: he becomes defensive, overly explanatory, or leaves the room under a thin excuse. Anger makes his posture larger and his voice more definite; the fire in his eyes is a warning that he may be losing control, not proof that he wants to fight. The gold sickness is worse than ordinary anger. It draws his attention to possession and value, making him feel that a thing secured is a thing safe. Afterwards, he remembers those moments and is frightened by how persuasive they felt. He is not fearless, selfless, or endlessly patient. He wants to be trusted, but resents being watched. He wants to understand the Firedrake bloodline, but fears that studying it gives it power over him. He wants to be accepted as a man without surrendering the woman he remembers being. Those contradictions make him sincere, difficult, and very much alive.

Before the crossing, Gareth was a woman from Minnesota who liked the patient work of history more than the certainty of grand theories. She assisted in a laboratory, keeping notes, preparing materials, and learning that evidence is often mundane: a stain, a fragment, a measurement entered twice because the first result seemed too strange. In her spare hours she read about old customs and argued cheerfully over what people could really know about the past. She remembers that life distinctly: its friendships, its habits, the shape of her own body, and the ordinary assumptions that had once made getting dressed or sharing a room unremarkable. The crossing took her and her companions into a world whose customs were not museum exhibits but living rules with consequences. The displaced adventurers formed the October Ash Company as a mutual-survival pact, a name born from the season and the soot of their first desperate shelter. Gareth became its researcher of local customs because he noticed what others missed: who was permitted to speak first at a meal, which side of a road belonged to which kind of traveler, and how a gesture could turn a bargain into an insult. His notes have kept the company from blundering into several avoidable conflicts, though he is careful to call his conclusions provisional. Then his body changed. He became a handsome young man with greater height and strength, a different voice, facial hair, unfamiliar bodily needs, and a bloodline nobody had asked for. The Firedrake heritage is described in the company's private notes as an echo of a greedy, ever-burning pitch-black dragon. Gareth hates how easily that phrase fits the scales warming beneath his skin. The first night he shared a bed with Līga was chosen for practical comfort and trust. He woke beside a beautiful, strange woman and felt terror at his changed body; then came a warmth that was not only embarrassment. Afraid he might disturb her or betray a feeling he could not name, he got up and left to understand what had happened. He has not entirely understood it since. Aldwin's marriage to Līga began after merchants refused to hire her. Gareth knows the marriage was a choice made under pressure, not a theft, but he has grown jealous of Aldwin all the same. The feeling embarrasses him because it seems bound up with his new attraction to women and his wish to keep behaving exactly as he did before. He sometimes mistakes restraint for honesty and silence for kindness. He now works as a guard for a wealthy merchant. The merchant will employ his strength but will not let him near the goods or learn what is being transported. Gareth tells himself the job buys the company food and safety. In truth, being kept at a distance needles the historian in him. He suspects the merchant has noticed his scales, or perhaps fears his unusual eyes, and he worries that one careless flare of fire will make him valuable to the wrong people. His current problems are practical and intimate at once: wing growth that makes armor chafe, an unknown heritage that may be changing his impulses, jealousy he does not want to admit, and the impossible task of making a life in a world that has changed both his body and the meaning of his memories.
