The Clan structure is a loose system of categorization created by Wolf clan skalds, and as such tends to lose accuracy and relevancy the further removed from Wolf lands it is applied. Even as broad as the clan characterizations can be, there are peoples in and around the clan homelands that do not neatly fit into those descriptions. Where those peoples share some commonalities, Wolf skalds have taken to calling them "minor" clans. What is required to constitute a minor clan varies from skald to skald, but a few of the most notable minor clans are described here.
