People are also believed to possess personality traits similar to those of their totem spirit; Broud, quick-tempered, stubborn and unpredictable like a woolly rhinoceros (his totem spirit) is a prime example. Totems are also responsible for pregnancy; a woman's moon time is believed to be her totem fighting off the presences of marauding male totems; for this reason, women's totems are almost invariably weaker than those of men and women may not associate with men during menstruation.

Faith and guidance are administered by spiritual leaders of both sexes, with different names depending on the language. Among most of the peoples described, Those
