Antillia Political Basics

Depending on the needs of the game the nations can change. I have a few interesting ones created.
Silnithar Elves are a group of Elves in the Silnithar Forest. They are very isolationist and do not permit anyone to enter their forest. Anyone who does enter never returns. They have had some bloody conflicts with the boarding Human kingdoms.
Magaria a magocracy that once controlled a vast network of Seams allowing them to have an empire that spanned multiple shards. About 100 years ago the Seams collapsed and the empire was just left with a small area of land on High Antillia.
Unbore a kingdom of Goblins that spans The Lock. On High Antillia the cities are mainly goblin. On Lower Antillia the goblins rule over human cities that they captured during The Golbin Wars.

Less developed areas
1-3 human kingdoms on Lower Antillia
The Serpent Valleys are home to many small halfling villages. Due to their inaccessibility, many of them are isolated and just trade with each other.
Some Dwarven tribes live on the Shattered Mountains
Near The Dragonspine some Dragonborn live in a river valley.
