Fogeaters

Fogeaters are heavily mutated ex-humans that reside in areas consumed by the Fog. Despite formerly being human, they exhibit no consistent language, society, or other usual characteristics of human groups. Instead, they gibber in various tongues seemingly related to many languages, including Aversarian; fight and coordinate as a single being during their violent ambushes, sometimes accompanied by a leader or shaman; and do not consume food or drink. Seemingly contradictory to this, they have a multitude of different tribes, distinguished by differences in their mutations, fighting strategies, and clothing, which can be further categorized into supercategories, of which four have been revealed: the Ironhewn, the Boneeaters, the Wightspoken and the Beastmasters.

Belief
The Fogeaters worship the fog. More specifically, they seem to worship an entity known as the Mistmother, who delivers knowledge about the world to the Fogeaters in the forms of whispers, including a garbled retelling of the Godherja, along with various other allusions to an entity known as the Mistfather. These whispers could suggest that the dead Mistfather is Aersanon, and that the Mistmother is Aelvar.

Tribes
The four known tribes of the Fogeaters are the Ironhewn, the Boneeaters, the Wightspoken and the Beastmasters. The Ironhewn are usually mutated to be much larger and stronger than the average man. They wear iron armor, which slowly fuses with and merges into their body. The Boneeaters are notable for worshipping bones, and they are unusually dedicated to retrieving their dead or captured. They wear bone armor, which slowly fuses into them. They also move in large numbers. The Wightspoken are powerful magi who seem to have degraded not only from humanity, but from reality. They are ghostlike and ethereal, but still have some functions of mortality remaining. The Beastmasters are the most intelligent of the Fogeaters, and lead pet fogbeasts into battle, hence the name. Their supposed intelligence comes from their tendency to be more vocal than the other Fogeaters, as well as mourning for their dead beasts in some circumstances. They normally mutate into more animalistic forms. It is known that at least some of the Fogeaters are descended from a tribe known as the Talareg, but it is unknown which groups and to what extent.
