Galma

Galma was a large island in the world of Narnia, located just off the coast of the Kingdom of Narnia in the Bight of Calormen. Galma was the nearest island to Narnia and was a duchy under the authority of the Kingdom of Narnia. The "Duke of Galma" was one of the titles of the King of Narnia. During the Telmarine Conquest, Galma became the first piece of Narnian land to fall to the Telmarines during the Siege of Galma and it was later used as a base to attack the Great River Delta in the Siege of Cair Paravel.
