The Kingdom of the Isles (also known as the Kingdom of Rillanon, and usually shortened to 'the Kingdom') is one of the most powerful nations in the northern half of the continent of Triagia. The mainland territory of the Kingdom stretches from the shores of the Endless Sea and the Bitter Sea in the west to the Kingdom Sea (Sea of Kingdoms) in the east. Its northern reaches are bounded by the Teeth of the World and the Northern Guardians, beyond which lie the Northlands. To the south, it shares a border with the Empire of Great Kesh. Culturally and politically, the Kingdom is divided in half between the older and more populous Eastern Realm and the Western Realm, which is governed from Krondor.
