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.
