Due to the unique nature of Istria's meteorology, the vast majority are born either of the Void or of the Fire, depending on the time and place of their birth: birth on the dark side of the planet, while inherently unusual, inevitably conveys upon the child a Voidsoul manifestation, whereas birth on the light side of the planet imbues the child with a Firesoul manifestation. As such, those Genasi born with a different elemental soul are typically revered as potential leaders of the Genasi race in times of dire need, and tend to be sent out to the society of different races to learn the ways of the world, as a means of education to promote diplomatic skills among foreign peoples.
The culture of the Genasi is one which abhors the human and dwarven cultures of lustful excesses, and instead focuses on flowery poetry addressed in apostrophe to beautiful men and women of other races, in the metaphysical style of Yon-dun, hero and lover of Genasi lore. However, they also have a noted love of haute cuisine, and the wine of the Tetuskf region of Istria is considered amongst the finest in the world.
A very xenophobic culture on the whole, Genasi politics are often dominated by reasons why they are superior to other races on Istria, which often leads to a sense of snootiness for those raised in predominantly Genasi regions--though they have become adept at hiding their racism in mixed company. As such, they tend to avoid wars, and are prone to frequent threat of conquest. Were it not for the anomalous birth of various Wind-, Water-, and Earthsoul Genasi at various points in their history, they would likely now be an equally haughty people under the thumb of some foreign race that was bent on Istrian conquest.
