culture.
"society" as we know it does not exists among varus, for more than one reason:
first, they are very few (something like fifteen millions, and, unlike what happens with us, this number is quite stable).
second, most of them are auto-sufficient: when a child becomes adult, it stop receiving help from his parents. only one thing is teached to young persons: 'teleirua' ("to carry off"), the art to survive and to build instruments.
Third, trade and market are not part of varus' culture, so a lot of typical human problems are totally impossible to understand by a varu.
fourth: apart from parent-child relationship, no-one ever offers food to another (i think this is the main reason demography is so stable). this kind of exchange is almost considered offensive ("do you mean i can't get food by myself?"... well, not exactly like this, but almost). so everyone is potentially autosufficient. i say "potentially" because groups (called emrati) of persons sharing food and other goods actually exists (but the exchange is restricted to the single emrati, so autarchism is still present, just on a different level). the oldest and most wise man in an emrati is called 'vanima'.
hunt and gathering is the main source of sustainment; agriculture in sot common but exists (mainly between emrati-people). when not looking for food, people usually follow their interests: mysticism, mathematics, music, physical activity, philosophy, history, lingustics, poetry, mythopoiesis are the most common activities. funny, isn't it. Due to the fact that everyone has to build instruments independently, technology never reached "human" levels.
another kind of social category exists: they are called 'uttaro'. some translation could be "herm" or "mystic wanderer". simply put, an uttaro is someone that refuses any teaching and wanders alone, living in a perennal vitalistic exhaltation. oddly enough, almost one varu out of four is an uttaro.
Someone could argue that between such asocial people, language could not even be born at all. actually, the opposite situation occurs: every family or emrati has its own dialect, and, despite the small number of varus, the biodiversity of language is remarkable. obviously, many uttaros can't even speak at all, mostly when they live as uttaro since a long time.
