In the Chronicles of Ancient Darkness there are no large forms of goverment. Instead people are organised into Clans.
Each Clan is named after a specific living creature, the clan guardian, who often has to do with the area in which they live. For example, you have the Seal Clan, who live by the ocean, and the Red Deer Clan, who live in the Deep Forest.
It might be possible to create new clans, since the already existing ones must have originated somewere. Michelle Paver mentioned that it would never be a Bear Clan since the World Spirit forbade it.
There are many different groups of Clans, named after the area they live in.
