The Sevari lived in clans that oversaw the mining and trading of spice, although the Empire controlled it during the Galactic Civil War, each clan having its own rigid social structure. Arranged intermarriages to avoid feuds were quite common. Each clan was ruled by a much respected clan leader, who in turn was subordinate to a clan lord who maintained stability over multiple augmentative clans. The strongest clan lords were granted the title of spice lords.
