Ketrefa

the phattest city in the highlands
discord info:
There is the monarch, who rules with rather absolute power. This can be a king or queen.
Then there are the noble families. These are bloodlines with an ancestor who was deemed worthy of privilege and thus granted legal rights beyond that of the citizen.
The nobility have the sole right to own farms. While they rarely farm the land themselves much of the food in Ketrefa usually can be traced back to their lands.
The noble families are also, to an extent, immune from punishment for lesser crimes. It's highly dependent on the king and communities opinion, but killing a thieving farm worker on the spot is usually acceptable.
The nobility alone can hold high titles. This means captains, so the ones who run the gates and the ones who run about getting slaves and extracting tribute from the other human towns and villages.
There is a essentially a cap on social mobility. A citizen can become rich, even own an established business in the walls, but never lead men in battle or hold any title of the sort.
