The blackened, rotten, and uneven flesh of a rimewalker is instantly identified as an unfortunate soul who died of frostbite. However, unlike the poor traveller who simply became lost in the cold, a rimewalker has chosen this fate willingly. They are the priests of Ull who, so devout in their faith, gave themselves entirely to cold, becoming intelligent undead in his service. They are rimewalkers, their sunken eyes glow white with a hatred for heat and flame, and the life that follows it. Patient, cunning, and ruthless in their pursuits, every rimewalker's ultimate goal is to extinguish warmth from the world.
