Two seperate races of people occupy and share the various islands of Unos. Humans were the first to strike out into the erg, as they were the first to discover and learn how to manipulate nemalnium. They are joined by the agamians, a species of reptilian humanoids of varying scale colors and a high breeding rate. The two species tend to get along, especially in the modern day, but racial scuffles aren't unheard of. After the terrible Hate Era, there was formed a mighty Union that now governs the world. It acts as a central force, to prevent open warfare and encourage discussion of opinion in its stead. People live day to day as a means of both surviving and thriving. Many respectable and recognized professions exist, from operations like sifting (mining) and hunting, to privateerism and merc work. Many young people choose to leave their homes and go across the sands in search of something more, often finding mundanity in life aboard a truck, or an untimely death in the sand.
