The social class structure of the Commonwealth is similar to a feudal system.
The classes of the nobility are as follows, from highest to lowest:
Exultants are the highest nobility of the Commonwealth. They are also the class which is not only a social construct; exultants are physically taller than other people. This is probably the result of genetic . The exultant class is in conflict with the Phoenix Throne for power of the Commonwealth; because of this, exultants cannot become autarch, and the autarch keeps a concubine from each exultant family in his Well of Orchids in the House Absolute.
Armigers are the petty nobility of the land.
