Coriakin's Island

Coriakin's Island or the Land of the Duffers (also called Duffer Island, Dufflepud Island, or the Island of the Monopods) was an island discovered on the great expedition of the Dawn Treader in 2307.

Coriakin's Island was the home of Coriakin, a former Star and Magician, and his subjects, the Duffers.

The island, as well as being filled with Duffers, also had on it a large mansion, which was Coriakin's, filled with his magical knowledge and spells. The island itself had had its gardens and trees tended to by the Duffers, who had fashioned them into odd but unique shapes and styles.

When the crew of the Dawn Treader came to Coriakin's Island, the mansion and the Duffers were all invisible, so they couldn't see anything except for the strange bushes. It was only when the Duffers told Lucy to go into the mansion (after they showed her where it was), to read the spell that would free them, and bring everything back into sight.

In the movie, six of the lost Seven Lost Lords found their way to Coriakin's Island, and asked him about The Green Mist that was threatening their world. Coriakin knew about the danger, and told them to go to Ramandu's Island.
