Planet: Capella IV. A moderately primitive humanoid society based on tribal leadership and strong codes of war. Led by a high male tier, their customs and traditions forbid shows of cowardice, and even forbid strangers to touch the wife of the high tier. This species tends toward resolving conflicts with their blades rather than with their words.
