Sea People

There are multiple kinds of Sea-People, Narnian Sea People, and the Sea People from the far eastern Seas.

Narnian Sea People
The Merpeople resemble that of a flying fish, with the upper part of the mermaid as a beautiful woman, and from the waist down is the tail of a flying fish. The merpeople sang at the Coronation of Peter, Susan, Edmund, and Lucy when they were crowned Kings and Queens of Narnia. The Merpeople are the fastest swimmers in the Sea of Narnia, at the end of the First Battle of Beruna the merpeople sang, rejoiced and leaped for joy out of the water in The Lion, the Witch, and the Wardrobe.

Eastern Sea People
These Sea People lived near the border of the Silver Sea. Lucy was the first to see them and was curious about them. She called Edmund over as well, but when Caspian saw them talking about them he ordered them back. This is a dangerous creature.
