Olin looks like a rangy, sun-warmed farm boy who has spent more time outdoors than indoors. His wheat-blond hair is clipped close around the ears and brushed forward with practical care; sun catches gold in it. His skin tans deep in summer and fades noticeably in winter, while his bright blue eyes keep watch even when the rest of him seems at ease. He stands taller than most his age, broad through the shoulders, and carries unusual strength with a slight lack of calibration: he can crack a chair rail by leaning on it. He walks with a hunter's quiet, economical steps, but his posture has none of a courtier's polish. Within a minute, people notice that he takes a measured breath before answering difficult questions, and that when rattled his breath catches audibly before he covers it with a blunt remark. His grooming is practical and consistent, an incongruously tidy fringe above mud-marked boots.

Olin is generous with food, directions, and labor when he recognizes someone as one of his people, yet can be sharp and ungenerous toward outsiders. He is brazen in a contest and shy when anyone praises his looks or asks about his feelings. Deep religious devotion coexists with an instinct to ignore rules he considers foolish. He loves the freedom of the woods but resents being sent away from home to perform a role for adults.

Arthur, the place-born embodiment of England, gave him the single name Olin and raised him as his son. Olin grew faster than anyone expected, outgrowing a younger northern brother and earning the uneasy attention of adults who thought a place-born child should develop more slowly. Rumors about whether Berwald, Nils, Allister, Rhys, Reilly, or someone else sired him have followed him since childhood. Olin treats Arthur as his father whether by blood or conviction, but privately regrets not knowing the truth. He remembers his mother in fragments, some tender and some he avoids examining. His earliest years held a rare peace: woods, small chores, and the comfort of belonging somewhere. That ended as his homeland grew louder and more divided. Watching ordinary people suffer while distant authorities argued changed his loyalty from obedience to protection. He is kind to his own people across class lines, yet can be callous toward outsiders, especially Europeans and the few native place-born he does not understand. Even so, their stories of thunderbirds and horned serpents draw him in, offering a vocabulary for things he cannot explain. Arthur sends him to socialize with Ludwig, a German place-born, in hopes of teaching him European manners. Olin began by needling Ludwig and now finds himself softening toward him. He hunts and traps for a living, competes for money at shooting matches, and is trying to learn what his changing sense of self means before someone else decides for him.
