Last Sea

The Last Sea was a near-saltless sea located at the south-easternmost edge of the world of Narnia. It was the nation/state of the eastern Sea People and was the area between which the salty Great Eastern Ocean transformed into the freshwater Silver Sea at the End of the World.

Caspian X and his crew aboard the Dawn Treader were the only known explorers of the Last Sea, located between Ramandu's Island and Aslan's Country.
