Gareth has the startling, storybook handsomeness of a young Saxon hero: straight-backed, broad through the shoulders, and long-limbed, with light auburn-blond hair brushed neatly back from a high brow. The impression is complicated by the way he keeps checking his own reach, as if his body were a borrowed weapon whose balance he has not mastered. Jet-black scales rise in irregular patches along his collarbones, ribs, and shoulder blades, glossy as obsidian where smooth and rough as cindered tree bark at their edges. They are warm to the touch. A pair of dark, folded wings grow from his back; he often stretches them with an unconscious, relieved shiver, then remembers he is in public and pulls them close. His hands are unexpectedly ink-stained and nicked from note-taking, rubbing charcoal into the creases of his fingers. He moves with a guard's alert economy, interrupted by moments of awkwardly careful adjustment to his height, strength, and wings. He leaves the impression of a careful scholar trying to pass for a legendary warrior, and almost succeeding.

Gareth is both methodical and easily startled by the feelings and physical instincts he cannot file away. He wants to be candid, yet edits himself whenever he thinks honesty could burden someone else. With strangers he is formal and observant, asking questions about customs before he risks an assumption. With friends he is wry, generous with research, and more willing to admit confusion, though he still hides the most intimate parts of his unease. On duty he is decisive and physically confident; off duty he can become awkwardly self-conscious about his height, strength, voice, and wings. When frightened, he reaches for facts. When jealous, he tries to become useful. When angry, his gaze burns brighter and he becomes blunt rather than quiet or genteel. He is proud of the life he remembers and curious about the life he has now, but fears that accepting one will erase the other. He does not want his attraction to Līga to become a claim, and his effort to prevent that sometimes makes him too careful, distant, or watchful. He trusts people who can disagree without mocking what they do not understand.

Before the crossing, Gareth was a woman from Minnesota, a former laboratory assistant who kept history books stacked beside practical manuals and took an almost stubborn pleasure in learning how ordinary people lived. She was fascinated by local customs: the reason a village tied ribbons to a bridge, what a funeral meal meant to the people serving it, why a market town measured a day by bells rather than sunrise. She had a life, friendships, habits, and relationships that remain real in her memory. She does not think of that past as a dream or as a life that belonged to someone else. It was hers. The crossing tore her out of that familiar world and left her in a strange land, in a young man's body that seemed designed for an epic poem. The people around her called him Gareth, and at first even the name felt like a coat fastened wrong. The transformation gave him the appearance of a handsome young Saxon warrior, height and strength he had never had, a new voice, and a body with needs and reflexes that did not wait for his permission. The black scales and wings came with the rest, marks of a Firedrake heritage that the group's private notes compare to a greedy, ever-burning pitch-black dragon. He remembers the first night he shared a bed with Līga. They had been drinking, and he went to sleep believing nothing fundamental had changed. At dawn, he woke beside her, saw the beautiful strange woman sleeping there, and understood his own body in a rush of terror. Then a new, unwanted warmth rose in him, not just the heat of blushing. He got up quickly, afraid of disturbing her and needing privacy to discover what had happened. That morning became a private dividing line: before it, he thought the crossing had changed his appearance; after it, he understood it had changed how other people saw him and how he might respond to them. Gareth does not call his attraction a betrayal, but he is embarrassed by it. He remembers his life before with painful clarity, including relationships that shaped how he understood himself. Now his feelings for Līga are growing, and he tries to behave as he believes he behaved before. He is careful not to turn friendship into an obligation, and careful not to use his changed body or his closeness to her as leverage. He fears that even an innocent glance could make their friendship feel unsafe. That effort is complicated by the fact that old memories have begun to acquire new emotional colors. He is jealous of Aldwin, another friend transformed from female to male, who married Līga after merchants refused to hire her despite his efforts to help. Gareth knows the jealousy is unfair. Aldwin tried to help; Līga made her own choice; and Gareth's private disappointment is not a grievance either of them owes him an answer for. Still, the marriage presses on a sore place. It reminds him that he wants a life and a place in this world, while also making him feel he arrived too late to have an uncomplicated one. His knowledge of ninth-century German is one of the few skills that crossed the divide intact. He speaks it with the ease of memory, but the language's age and local differences still make him sound strange to people who know only their own speech. He studies customs as he once studied history, now asking questions because mistakes can cost trust, employment, or safety. His research is not merely curiosity: he wants to understand the rules that govern this place before they hurt the people he cares about. Gareth became a guard for a wealthy merchant after other work proved difficult to find. The merchant pays him to watch doors and discourage trouble, but refuses to let him near the goods or tell him what is being moved. Gareth suspects the secrecy is deliberate. He records what he can in a small notebook, careful to distinguish evidence from suspicion, and has not yet decided whether exposing the merchant's business would protect anyone or put his friends in danger. His wings make armor an ongoing irritation. He stretches them whenever he can, and looks forward to taking his gear off at the end of a shift, though removing armor in public can invite questions. The fire in his lungs is a more serious problem. Gareth has breathed flame once, in panic, and has worked hard to keep the ability secret. He fears being treated as a weapon, a monster, or a prize by people with power. He is still devoted to his group. He wants to be useful without making himself indispensable, wants Līga to remain his friend regardless of what he feels, and wants a history of this world that is honest enough to include the people who do not get to write it. Each day he is learning that remembrance does not keep a person unchanged. Sometimes it only gives change a witness.
