Because this is a fantasy and I absolutely love wold-building, I am choosing made-up names for items. I welcome anyone who wants to draw what they think any of these things might look like to e-mail me their pictures. I promise to post them!
Kwenda of the North:
Trade with Xolanh
Fish from Dwoba & Twea
Chash grains from lower Kwenda
Voi orchards--lower Kwenda
Bahga herds--Upper Kwenda
Disse wood from Dwone forest
Videsse of the North East
Fish from Rydie and Baikessa Seas
Fish from the Ehrene Lake (Sea)
Kavar furs from the Ekida mts.
Three ports & geographic location = shipping & commerce center (potential piracy)
Lartiene of the East
Fish from Baikessa and Ehrene
Trade with Jodair
Dalki, Besso, Vahg = crops
Shair, Lomi, Boona = herds
Sanara of the South
Baikessa Straight = fish
Trade w/ Jodair
Jordelle and Hallone Lakes
Fiar crops (like barley)
Fiada = (like beer)
Chash, Besso & Avikan = crops/grains
Boona and Twenni = herds
Togan of the West
Forest & Plains & Crops
Herds: Genn (like horses), Ipha (like donkeys), Bahga (like cows)
Lumber = Disse, Jolar, Enda
Crops = Fiar, Chash, Voi, Temm
Types of crops that show up repeatedly are essential to the regional diet.
The countries that have more resources are more wealthy, and also more hierarchical. Hierarchy and agricultural surplus go together.
The realms that have the most wealth are Sanara and Lartien. Seeing as they ahre a border, it makes sense that these two places are likely either a) at war with each other or b) on the verge of conflict.
The fact that Kwenda has a distinct crop region and distinct pastoral region means that it is likely Kwenda is composed of two ethnic populations. This can produce off and on internal strife as the governing system attempts to force cooperation between two peoples that see themselves as distinct. Whichever group holds authority will be instantly seen as the oppressor by the unrepresented group.
The long coastline and minimal resources make Videsse a trade center. The easy access to the outer islands mean that this people can easily have a pirate population. Videsse does not have as strong of an internal division, and so while on the fringe of the society, it is not subject to the same internal strife.
The abundance of grass plains and herd animals means that Togan is primarily pastorilist. As such, these people might not be seen as positively by the more hierarchical realms of the east. As there are some crops along the border, and trade might be common, there might be some individuals who leave Togan. The crops are likely produced on a much smaller scale in Togan than in the eastern realms. This means that it makes sense that the people would be horticulturalists rather than agriculturalists ( meaning that the emphasis is on subsistence rather than surplus) but when surplus is produced it is likely traded.
The socio-cultural and political map of Chiadina can then be developed more closely through the eyes of a particular character.
