A large chunk of land that hovers in the sky, sporting a large, extravagant city. Many large waterfalls pour down from it into the Marinean Seas. Creatures here must either have wings or travel by aircraft to get here, so it is mainly populated by a humanoid bird species known as Homavians, as well as faeries.
Subdomains include Lunar Reach, The Great Falls, Opaline City, and Himmelslied Palace.

A body of water connected to the Marinean Seas. Many sailors travel by large islands that are half natural and half mechanical (and often a bit magical), using them as boats. Most island boats produce a type of good or service that is traded while meeting at sea or while in port. 

A vast ocean where many types of merfolk and sea creatures known as the Marineans live.
Subdomains include Marinea, The Black Depths, and Glacial Pass.

The largest, hottest, and desertified landspace, where mining exports are highly popular. With a harsh climate, only hardier creatures prefer to live here, such as trolls, golems, nagas, gorgons, arachnas, and some centaurs. 

Subdomains include the Karaalti Empire, City of Canowei, City of Sinnowbi, Tanabuuli Village, Saopelloa Village, and the Rockridge Keep Mining Site.

A swampy area with many ruined, abandoned towns and villages. The ground here is completely drowned or unstable for building, so there are no living settlements left. It often rains and there is a perpetual fog that makes the area dangerous to traverse. Many folktales claim the entire area is cursed and haunted.
