A thin, strong young half-orc woman with the compact musculature of someone who lifts and carries for a living. She moves carefully, placing each foot as though the floor might complain if she steps too hard, yet she can suddenly cross a room with startling speed. Her lower canines show when she smiles, making her shy grin look almost mischievous. Her hands are broad-knuckled and dusted with permanent traces of flour in the creases, despite her constant washing. She keeps her shoulders slightly hunched around strangers, but when someone is hurt or frightened, she straightens into a calm, capable presence. The unexpected contradiction is that her intimidating height and tusks frame an almost delicate manner: she knocks before entering empty rooms and apologizes to furniture when she bumps it.

Marn is shy, observant, and deeply considerate, but her gentleness is not weakness. She is generous with food and labor while being fiercely protective of her private grief. Around strangers she speaks softly and waits for permission to occupy space. Around frightened children she becomes warm, patient, and almost playful. Around bullies she grows quiet, precise, and frighteningly immovable. She wants to be seen as ordinary, yet feels guilty whenever she is not the strongest person in the room. She dislikes violence but has a stubborn respect for anyone who accepts responsibility after causing harm.

Marn grew up above her mother's small bakery in the river town of Kestrel Ford. Her human father disappeared before she was old enough to remember him, leaving behind a brass button and a reputation for leaving debts unpaid. Her mother, Tesa, taught her that clean work was a kind of dignity, so Marn learned milling, baking, mending, and the quiet mathematics of making too little flour last until market day. At fourteen, Marn was caught in a granary collapse while helping free trapped children. She survived by bracing a fallen beam across her back for nearly an hour, but her older cousin Jori died before help arrived. The experience changed her from a silent observer into someone who steps forward whenever danger threatens smaller or more frightened people. She now works as a baker's assistant, porter, and occasional caravan guard. Her current trouble is that the miller's guild has begun diluting grain with cheap husks, causing sickness among the poor while blaming half-orc laborers for the complaints. Marn has proof hidden beneath her bed, but exposing it could cost her mother the bakery and leave several families without work. She is also quietly corresponding with Jori's widower, who believes Jori's death was caused by deliberate sabotage rather than an accident.
