The lands of the Thalassan Sphere
Since the Cataclysm caused the oceans to rise dramatically, the only land above sea level is in the form of islands, the largest of which, Bitu-en-Sul, covers about a million square miles north of the Ring of Fire. Thousands of islands exist and hundreds have people on them. This is not a comprehensive list.
Anover and Avari
Anover and Avari are two islands slowly joining each other as the waters recede, one ruled by a thaumocracy, the other by the Gegenzauberer, a group that has forbidden all unsanctioned magic and purged itself of magic users as best it could.
Cenwulf Protectorates
The Cenwulf Protectorates are a chain of islands in the southern part of the Rim. A stable, cosmopolitan society that came through the Cataclysm with their decency intact, they are the height of civilization in the Thalassan Sphere. Just ask them. They'll tell you.
Hagiv
Hagiv is an island of roughly 100,000 square miles, less than 2,000 miles from the Cap, Hagiv is a closed society run by a Glorious Leader and a Revolutionary Council. Following the Cataclysm, Hagiv was a monarchy. It became a Thalassan protectorate in 126 DB. Between 488 and 520, it underwent two violent civil wars, which led to the current administration.
