Society is broken up into (as far as classes):
>Undersights
Slaves who were former criminals and captured soldiers, except in the south. Due to an extended war with a southern country, in which one of the states attempted to secede, the nobles behind the succession + all their families and associated peasantry + the nobles involved from the southern country were made into slaves. Slave law is also much closer to entrapment in the south, with many peons getting caught up in it.
Slaves do not have rights under the Bloodlaw, and are exempt from the aforementioned moral codes, their reputation is based on their master's reputation.
The time that a person serves as a slave varies, but there certain crimes (called 'Unsightly Crimes') that call for lifetime slavery.
>Peons
A person from the low class, 80% - 90% farmers and associated workers. Peons are technically under a protected status under the Bloodlaw, but that has waned over the last 200 years or so.
>Merchants
Another 'protected' class. Stealing from merchants will invoke either the loss of a hand or five years slavery (which you are unlikely to survive if not born to it).
>Lawmakers, Judges, Lawyers, Guardsmen, and General Clergymen
With religion and law being heavily entwined, these groups enjoy a respected status in the four states, with some Judges and Lawyers in particular being equivalent to minor lords.
There is a separate branch (the general clergymen) that focuses on simply worship rather than law + worship, and they enjoy the same status, but have no real legal or religious power.
>The Ruling Nobility (Delphines, Low Princes, Grand Princes, and Serenes)
Loosely equivalent to Counts, Barons, Dukes, etc. 'Fathers of the Realm', according to the Bloodlaw, they are to be highly respected, but also are to lead by example and be of exemplary moral character.
The ruling nobility refers to the ruler and their extended family only, there is no legally defined 'noble' class.
