"The five islands floating in the sky are called Whales. Each Whale has its own nation. The five nations are: our very own Sadal Suud Frontier; Diadem, Land of the Clouds; Anuenue, the Rainbow Nation; Mira, City of Illusion; and, of course, Alfard Empire." As told to Kalas and Xelha by a man in Sadal Suud
The five Great Nations create balance between one another and are the main bodies of land found in World of Baten Kaitos. Each continent houses one of the five End Magnus.
