Dark Sun: Seared to the bone
Within the walls of a city-state, every person has a specific place in the social order. Sorcerer-kings rule, supported by nobles and templars – the priests and warriors of the monarchs. Merchants and craftsfolk, as well as warriors in their employ, enjoy positions slightly higher than those of beggars, farmers, herders, and laborers. Slaves toil in the lowest level of society, giving their lives in forced labor, gladiatorial spectacles, or outright sacrifice.
On the other hand, those who dwell in villages or nomadic tribes in the wilderness value freedom and competence, and they believe, perhaps rightly, that city residents lack both. (Of course, the most independent tribes still have leaders and members with more wealth or status than others.) Liberty comes at a high price, however, since the wastelands of Athas are treacherous even for the well prepared.
