The clans heavily influence gnome society. A clan consists of a large group of families related by blood or marriage. The clan is often centered on a common interest or business, such as gem cutting or mining. Each family within a clan specializes upon an aspect that supports their clan's activity, either by perfecting the art, researching new ways to employ it, or protecting it.

The clans have traditions and secrets that are claimed to originate from a common ancient ancestor. Gnomes are very loyal towards their clan, and not only because it consists of their relatives. Education, spiritual guidance, employment and protection is commonly provided by the clan.

Knowledge and skill are important factors when establishing the position of a clan. Library size and the number of scholars and renowned experts are factors that are taken into account. Personal status is determined by the clan's prominence in comparison to other clans, as well as an individual's status within her clan.
