The Tribes are denizens of the Otherworld that represent and embody specific mysteries of life and development – e.g., Birth, Memory, Initiation, Magic, etc. They are grouped into clans/tribes named for specific earthly animals that also represent these mysteries through long cross-cultural associations. The Tribes-folk have the ability, per shared experience in Waincraft, to assume the shape and mannerisms of the animal associated with their particular Tribe, and some have the ability to shift into other shapes or forms as well.
There are 23 Tribes officially recognized by the Waincraft model, each of them associated with an animal that holds sacred meaning throughout Eurasia (and, often, elsewhere in the world). Most of these animals can be found, or have analogous species, throughout the human-dwelling world.
