Coriakin is a magician on the second island the Dawn Treader reaches.  The Dufflepud creatures fear him and call him The Oppressor because he made them invisible, but Coriakin actually made them invisible to protect them from the evil mist growing all over Narnia.  He cares about them and wants to protect them even if they don't recognize or appreciate his efforts.  He lives in a huge invisible mansion on the island surrounded by thousands of books and magic.  He warns the travelers that they will not be able to defeat the evil mist if they do not defeat the darkness in themselves first.
