Here's the entry modified to refer exclusively to the tribe instead of the kingdom.
The Avennorian Diet is composed primarily of seafood, particularly yellowtail and oyster for the common folk and malkut king fish for the more wealthy, although most of those who can afford a king fish can also afford to import meats from the neighbouring province of Sanguia, among other imported goods, which are usually considered more high class in Avennorian society. It should be mentioned, however, that there is some small scale farming within Manthria, the biggest being the Twynor farmsteadings. A staple of all Avennorian diets is flysh seaweed, which is used as a base for many Avennorian dishes or is baked into a bread. Another traditional import among the Avennorian people are the products of Eyelian agriculture, as they serve as a refreshing change to the monotony of seafood that is so common in Avennorian culture.
Traditionally, Avennorians are primarily fishermen, pearl divers, whalers, and merchants, though of course all of the miscellaneous jobs for each town are, and have always been, available (blacksmiths, jewellers, etc.)
Fishers and Whalers-
These are the biggest industries of the province of Manthria, though that doesn't mean that they are its best paying ones. Whaling is slightly better paid, as whale products are Manthria's largest export, though it is still considered a commoner's job. Fishing and whaling employ a large portion of working class Avennorians, who have colloquially titled themselves "Harvesters of Baveras' Bounty". The people in these jobs make up the backbone of the flourishing Avennorian economy, a fact which they never cease to pride themselves in.
Pearls were one of the kingdom of Avennoria's most famous products, and today one of Manthria's most sought-after goods.. Merchants from all over Sarvonia come to the port of Ciosa or the city of Marcogg to trade for high quality Avennorian pearls. Pearl divers are the ones behind this large sphere of influence held by Avennorian traders. It was originally through trade of pearls that Avennorian cities became the bustling hubs of trade they are today. Pearl divers themselves are more respected than fishermen and whalers, particularly those who are able to close their ears to enhance their skills.
Merchants are the smallest, but most influential, group among the Avennorians. They are the cause of the image of Avennorians as a whole being that of wealthy and powerful, albeit somewhat ruthless, traders. For an Avennorian, being a merchant means doing what you need to do to get to the top. Though they make up only a small portion of their society, they regard themselves as being superior to all the social classes below them, to the point of considering themselves above the law and/or their own human morality, or at least that's how the rest of their society views them. When one of them was asked about how they felt about this representation of them by the author, they laughed and said that the masses were "naught but jealous swine who believe they should be treated as human."
Prior to joining the United Kingdom of Santharia, Avennoria was ruled by an aristocracy where the person with the most wealth usually became king. Because this requires the king to remain the wealthiest over the course of their rule, it was not impossible for the king to get overthrown purely on the basis of temporary shortages in his/her flow of income. However, it was also not a frequent event, so most of the time, the king could simply pass his/her wealth onto the next generation in his line without trouble, sometimes for four or five generations in a row.
Due to this form of government not requiring any leadership skills to become king, kings were, more often than not, much better businessmen then they were governors. This usually led to lots of back door dealings, including, but most definitely not limited to, buying government jobs, using parts of -and in some cases - the entire - kingdom as collateral, passing laws for the highest bidder, and, in one circumstance, renting out the position of king for a "small" fee to those who were willing to keep their mouths shut on matters that were never disclosed, even to this day.
