Major language groups and dialects
Hiva have a rich and lyrical language, but it has no written form at all. Some Naacal scholars had tried to write down some of their myth sagas and poems but they refuse to "see the soul of their words trapped in paper". More information on languages can be found here
Shared customary codes and values
THOU SHALT NOT ACCEPT THE WRITTEN WORD The Hiva Tribe hates writing: they see it as a weak practice, and too similar to witchcraft. For them, oral culture is the only way of transmission that carries truth within it, and it is oral word the only one that reflects the power of the Great Spirit. Tribal Tradition rules: Hiva characters will never learn to write or read any language, no matter if it is during their creation phase or later. If they try to do so, they will risk to become Tainted.
