Silver Sea

The Silver Sea (originally, the Lily Lake) was a small freshwater sea (although possibly an enormous lake) that extended off of the Last Sea and was the closest body of water to Aslan's Country. It was the most eastern body of water in the world of Narnia.

It was a great flowing sea of clear, sweet, saltless water naturally covered by myriad floating lillies. Caspian X discovered and named the sea during his voyage aboard the Dawn Treader during the Narnian Age of Exploration. Crewmember Reepicheep disappeared through the tower wave that he believed lead into Aslan's Country. The sea also met a grass plain at the end of which the sky touched the edge of the world. The water was so sweet that Caspian called it "drinkable light." It was also the frontier of the eastern Sea People.
