The Rimekin are the fire-keepers of the Frostmarch Hills, a hardy people whose clans survive by memory, mutual obligation, and a stubborn refusal to let winter decide who gets to live. They read avalanches like written warnings, carve family histories into boundary stones, and carry living embers when they travel. A Rimekin adventurer may be a clan exile, a wandering guide, a shrine-keeper seeking lost songs, or simply someone who has learned that the wider world contains dangers no blizzard ever taught them to expect.

Rimekin are compact, broad-shouldered humanoids shaped by generations in bitter uplands. Their skin ranges from slate, umber, and blue-brown to pale ash, often marked by freckles that resemble scattered snow. Hair grows thick and insulating, commonly in white, silver, charcoal, rust, or deep brown. Most possess small crystalline ridges along the ears, brow, elbows, or knuckles. These ridges are not true horns, but mineral deposits that grow slowly throughout life and are polished, painted, or carved as signs of identity. Their eyes reflect dim light with a soft glacial gleam. Rimekin body heat is unusually well regulated, and their breath remains visible even in mild weather.

Rimekin society is organized around hearth-clans, extended families joined by shared labor and a common ember. A person may be born into one clan, adopted by another, and sworn to a third through marriage, rescue, or apprenticeship. Leadership is divided between practical stewards, who manage food and defenses, and memory-keepers, who preserve law, genealogy, and sacred stories. Disputes are traditionally settled during the Long Table, where both sides must eat from the same pot before speaking. Rimekin value competence, reliability, and the ability to remain calm when plans fail. Festivals are rare but intense, featuring drum circles, ice lanterns, fermented root dishes, and contests of storytelling.

Rimekin spirituality centers on hearth spirits, ancestral echoes, and the immense patience of the hills. Most clans honor a different collection of local powers, but nearly all recognize the Three Watchers: the Flame Below, the Wind Above, and the Stone That Remembers. Their rites involve shared meals, ash markings, carved offerings, and long periods of listening in snowfields. Rimekin are often neutral or good, valuing survival through cooperation, but strict clan traditions can produce lawful communities and fierce individualists alike.

Rimekin settlements are built low against the wind, with stone foundations, turf roofs, and communal halls sunk partly into hillsides. Their most important structures are hearthhouses, each centered on a smokeless ember basin fed by mineral-rich peat. Bridges are made from lashed timber and mammoth-bone analogues, while boundary stones bear layered carvings that record weather, treaties, deaths, and safe routes. Wealth is commonly displayed through well-maintained tools, abundant fuel, and carefully repaired walls rather than ornament.

Rimekin respect communities that share food and shelter, regardless of ancestry. They often admire practical folk such as miners, shepherds, caravaners, and village healers. They have a wary relationship with lowland nobles, whom they see as people who inherit warmth without understanding its cost. Rimekin generally distrust raiders, wasteful hunters, and anyone who treats the Frostmarch as an empty wilderness. Among other peoples, they are valued as guides and negotiators, though their blunt hospitality can be mistaken for suspicion.
