Do you this this is too many languages?
Oddly, the name of them reminds me of the Spanish word for fish Pescado. This was entirely accidental, as the gods were named by me thinking about my concept for them and the uttering sounds until I found ones I liked. At any rate, on to the more interesting information.
They inhabit the coastline, and a small chain of islands off the southeast part of the continent. In the early days, they survived mostly on fish and Borede (see below). Still very tribal and "backwater" by the standards of the city-dwelling Kalians (To the point where "Pestun" is more often used as an insult than a correct Adjective in Kalish). "Fisherman" (and I do mean man!)
is the most honor anyone not born into the monarchy can achieve.
While the men are doing manly things, like hunting fishing, cooking, sewing and cleaning the women sit around chatting all day. The men are the concrete need of the culture, and the women are the abstract need of the culture (this is not unlike the Daronain, but it is executed very differently). The women, however do not mind being though of as only good for painting and writing.
If a boy can not prove his worth (which has gotten easier as things have gotten more relaxed in modern times) by the time he is a man (looses his virginity) he is taken out on a ship and cast into the sea. If he survives, he has to find somewhere else to live because he's only lucky and that won't pay the bills (which is now in the expression "One can't live on luck").
The Borede (Bo as in Boat, Ray like the shortened form of Raymond and De sounding like Day.) is a melon which on the outside is a striking and vibrant red color, which fades into black stripes. The flesh inside (the part of the melon you eat) is vibrant green color with Ivory seeds. These melons grow in tall trees grow on tall treas with large leafy fronds. They have little nutrients but are very wet, which is important on an island surrounded by saltwater. This of inside-out watermelons (but more spherical) growing on palm trees.
When children ask where babies come from, parents (usually mothers, as the overworked fathers are off... working) are told of a large palm tree on an island "Just far enough off the horizon" (usually assisted by the mother pointing out of the window, or off to the nearest coastline) "that you can't see it." where Borde melons grow. "Borde bigger than any you've ever seen." And once they are ripe, they fall off the tree, roll off the island and wash up on the shore where the king cracks them open and gives the baby to a lucky young couple to raise.
Mystic forest dwellers, who are not as gentle as they once seemed. It is again a theme that Men are concrete and Women are abstract, but for a mystic the abstract is more important. Unlike in the Pestuan culture, where the less-important women are free to peruse hobbies (and not killed if they can't prove their worth!) the Daronains make the men work for them.
The women are the masterminds behind the "Grand Plan" (which is a secret that all Daronain women know and none ever deluge), which is rumored to not exist. Men toil away in mills and factories, and must bring home the bacon, fry it up and keep her satisfied. Homosexuality is very taboo in this culture, but only even noticed if it is between women. Men are expected to be simple and not understand the "Natural Order".
Being mostly traders, and given how polite the people are, it's sort of a wonder that "The costumer is always right." appears in none of the holy texts. The language itself has many odd levels of politeness which apply to many different situations. They will take anyone in, as long as you've got the dough. The Head Merchant, who manages the outpost, is also the political leader. As a country it is a political wildcard, as one Head Merchant may differ drastically from the next.
One word to describe them- "Pretentious". Imagine your inner-city college kids who drink coffee and complain about how their lowest grade is a "B" because the professor hates them. Imagine an entire city of them who follow religion blindly, and will preach endlessly but still however believe that everyone is entitled to their own, wrong opnions.
Somewhat cultist, and very secret they shun most other cultures (a few are adopted in under very rigorous conditions). Most of their culture centers around religious life, but it actually has something to do with religion, as opposed to talking about it endlessly.
The written language is Ideographic, and many written words have no phonetic representation. Pronouns are used often to confuse anyone who might not already have a context to put the note in. Literature is not popular in this culture, but improvised dramatic productions are.
