Brief description:
Grams
Currently the biggest kingdom on the continent ( and by a lot )
Has Dras as a vassal state, most of it was turned into military.
Doesn't specialise in production or development of a specific field, but since it's strategic placement in the general upper part of the continent, it is a very important place of trade in the north. Although it's economy is largely independent on outside sources.
The current King Gars is relatively old but still stands strong, since he usually tries to achieve "peace" between nations at the with the threat of a war he has earned a nickname "Soft Tyrant". His idea of peace is that he can do anything and everyone will not stir up problems with opposing him.
Dras
Very small country on the southwest border of Grams. Few decades ago it was defeated in a large scale conflict by Grams and now serves as a vassal state. Dras has been known for having especially strong army, mainly because of their unconventional yet effective methods of training their soldiers.
Dras currently works as the base of operations for Grams military. All civilians were moved to Grams and most military infrastructure was directed or fully moved to Dras.
Sewol
Not much here to say about it. Average kingdom at best. Mainly specialises in refining or producing precious metals, although not in big enough scale to be considered a major production hub for it.
Fosënċen
Located in the middle of the continent. Fosënċen profits dearly from trade but the kingdom mainly focuses on producing weaponry. Their main customer is the vassal country of Dras.
It is one of the few human led nations that practice matriarchal hierarchy.
