Clans
Clans represent major extensive families, or in some cases, family-like organizations. A kingdom is usually made up of several clans who hold fiefs and lead its troops. A clan will have a ruler, and when that ruler dies, the clan's leadership and titles will pass to his or her heir. Clans are nominally bound by blood ties, but marriage will result in one of the spouses (usually the wife) joining the other's clan, and sometimes clans will adopt members.
