Mairi is a compact, weather-hardened human woman with ruddy brown skin, steady gray-green eyes, and dark auburn hair usually braided close to her head. A pale scar crosses her left eyebrow, and her hands are marked by old cuts, calluses, and faint traces of herbal dyes. She wears well-maintained chain mail beneath a travel-stained blue-gray cloak, carries a battered wooden staff, and keeps her silver holy symbol tucked beneath her collar when traveling among strangers.

Quietly attentive and difficult to rattle, Mairi notices small signs of pain that others overlook. She is practical, generous with food and shelter, and deeply uncomfortable with grand speeches about destiny. She prefers to prove faith through useful work, clean bandages, shared meals, and staying awake beside the sick.

Mairi grew up in a scattered human settlement on the edge of a vast moor, where the roads faded into peat tracks and every winter tested the strength of the people who lived there. Her mother taught her which roots eased fever, which birds warned of storms, and which stones marked safe passage through the bog. Her father, a caravan guard, disappeared during a spring crossing, leaving Mairi with a deep respect for the dead and a lasting suspicion of promises made by comfortable people in warm rooms. As a young woman, Mairi joined a wandering shrine devoted to a kindly guardian deity of hearths, roads, and healing. She learned the prayers of a cleric while escorting pilgrims through wilderness, tending injuries, burying travelers, and offering shelter wherever she found it. When a wasting sickness struck three remote villages, Mairi stayed behind after the other priests fled, using prayer and field medicine until the disease passed. She now travels beyond the moors, searching for the source of the illness and carrying her faith to people who have no temple nearby. She believes no one should have to earn compassion by first reaching a place of safety.
