Its creatures draw on folklore and fantasy, including cruel fey spirits, relentless hunters, feral giants, and threats born from the tundra itself. Each entry includes lore, ecology, and distinctive abilities, with challenges ranging from CR 1 to CR 17. The 40-page volume also features full-page illustrations, a full-color layout, and printable miniatures.
