The Divide
Surrounding Countries
To the north of the Divide is the Northern Lethea region and the Empire of Lorgzilin, a state with a brutal absolute monarch who demands his servants worship him as a God. The Divide is referred to as the Southern Wall by the Lorgzilians.South of the westmost end of the Divide is the Kingdom of Hlulane and their overlord, the Empire of Le Zhea. Le Zhea used to own everything south of the Divide, back when their country was still called the Empire of Lethea. The Divide was the main reason why they couldn't expand northward. Attempts were made by invading through the western passages, but they weren't prepared for the temperatures that awaited them on the other side, the narrow and bumpy passages had made logistics a nightmare as supplies had been hard to come by and getting wagons on the other side safely was, and still is, a challenge.
South of the Divide in the Southern Lethea region lies the Theocracy of Athe, the Federal Geniocracy of Ithelmark, and the Federal State of Alminthas. All three of those countries have criminalized attempted scaling of the mountain range. The punishment is different in each country. In Athe, it's a hefty fine, but in Ithelmark and Alminthas the fine is small, but they also include public humiliation.
There are plenty of small tribes and petty kingdoms that are also next to the mountain range, but as there are too many of them and as they aren't recognized as proper states by the international community, they will not be mentioned.
Geography
Going around the mountains is far easier, especially from the southern passages. The northern routes are colder and more dangerous, but still far safer than going straight over the mountains.
Nice map Dhelian! I know you're probably still working on it, but remember to link wherever it is! I'd love to see what nations are around it :D
