The Cayne Islands (pronounced cane eye-lands) is a large tropical island archipelago that lies in the Simmering Sea between the continents of Amarja and Souldrus. The archipelago is estimated to contain over four thousand islands. There are eleven large major islands that have served as a hub of culture and soceity for the islands for several thousand years. The islands were once politically independent as the Cayne Kingdoms, a number of tribal kingdoms that existed on the major islands. The islands have become the victims of colonialisation, first by the Souldrus Empire and then by the Third Republic of Yio.
