Air Genasi Caste System

Air Genasi society is a culture propped up by stringently defined and divided social class boundaries. These social classes have interestingly enough developed paradoxical subcultures as a result. Each class stratosphere has it's own mythological traditions and practiced customs. There are five caste structures and a more ephemeral sixth caste, the only one that one can transcend into without division -- The Ruler. The vagrants, wastrels, and otherwise undesirables make up the lowest caste, the Hundun. The peasants of all variety make up the second caste, the Xiaqu. The skilled laborer's and merchants make up the third caste, the Zhuanke. The warriors and mages skilled in the arts of war make up the fourth caste, the Jian. The noble and hierophants, with some separation but relatively continuity between roles, make up the fifth caste, the Daoshi. The final caste, that of the ruler is called the Wangguan or is commonly referred to as the Grand Guan.
Pride comes in all veins here and no one is more proud of the class than which they were born. Exchanges, however rare, between these social classes are met with intense and expressive manifestations of disdain. This disdain precipitates from both directions, social class 'transcendence' is equally derided by the upper class as the lower classes. Staying in the role dictated by your birth is not only implicitly suggest but explicitly forced. These manifestations have been known to explode into the violent altercations and murder where individuals from both classes assault or assassinate the individual who stepped across the line. Necessity sometimes allows for this transcendence, but few have enough power beyond the royal family and its advisors to halt the pogrom that would almost invariably ensue.
