Great Eastern Ocean

The Great Eastern Ocean was the main body of water to the east of the Kingdom of Narnia from its peninsula, later island capital of Cair Paravel, in fact, the only ocean in the Narnian world to truly be explored. The Eastern Ocean consisted three notable bodies of water, including the Bight of Calormen located on the Narnian coast (also a nation/state where the Narnian Merpeople lived). Islands in this ocean included Galma, Terebinthia, the Seven Isles, the Lone Islands, Dragon Island, Burnt Island, Deathwater Island, Coriakin's Island, Dark Island and the Island of the Star. Beyond these islands where more known countries, including the Last Sea, inhabited by the eastern Sea People, beyond this was the lilly filled Silver Sea, the last body of water before the world's edge. Finally, there was the Utter East, a patch of land on the world's eastern edge that shared a border with Aslan's Country.

When the world had ended, it's inhabitants left their lands and entered Aslan's Country threw the Stable Hill. The water levels arose signifigantlly higher and when Father Time had destroyed the Sun and Moon, it had completly froze into solid ice.
