Enkarlia

Backround
Enkarlia is known as the Kingdom Below Sea level because it is almost completely submerged. From what you see on the map there is a small ring with a circle in the center. But all of Enkarlia is under that, and a little farther out. From the ring, a dome is formed made of solid air, and this solid air also reflects whats above it making Enkarlia completely invisible from the outside. The Solid Air is unbreakable just like how the frost ice is unmelting. You may have thought the people living in Enkarlia were sea creatures but they are not. They breathe air just as the people of the surface do. Though they are accustomed to the feel of water and when or if they go to the surface they are bound to be on the sea.
