There are two main continents, "Eldoria and Kryton". Most of the big cities belonging to the Vector. The rest is unclaimed or controlled by individual parties.
Within the archipelagos, many different races normally dwell within the islands and control over them is normally bought or traded between businesses and individuals. The Anarchic Archipelago is controlled by who ever gains enough power and influence to be the Chaos King. Draconta Archipelago is controlled by no single individual but a hierarchy of dragonborn authority. The Lost Isles of Dinara is a mysterious land unknown to have a ruler.
The Vector has hired 7 pirates to help establish control. Two of them have their own island, "Scale Isle" and "Frostbite Isle" while the other 5 stay at Honeycomb Island. They also control the Fortress of the Iron Tide, Isle of the Forsaken, and Sanctum of the Ancients.
Other islands are controlled by individuals and businesses. Asthym's Hollow is a secluded island protected by samurai on the outskirts with elves are inland. Aetheris Isles is a cluster of magnetic islands suspended in the sky, not controlled by anyone known to the public named Aeolia. In fact only one island is open to the public and the rest is restricted under the Vectors orders. Secretly controlled by The Wither of the Domain.
