Numerous islands and archipelagoes dot the Eastern Ocean. Most notable among these are Galma, the Seven Isles, and The Lone Islands; all subjects of the Narnian crown, and Terebinthia, an independent island. At the far end of the Eastern Ocean the geography becomes completely fantastic (as a result of the Narnian world being flat) where the sky meets the surface of the earth; in addition, it is implied that a passage to Aslan's Country is located there.
