Prince Edmund is the Prince Heir to the King of Blest. In the book he is only 18 and just learning his duties. There is not too much to say about him, except that he's young, he does nothing to save the kingdom from the conspiracy, and nothing to show any worthiness of such a powerful throne. Although fascinated by the new young Merlin when Magid Maxwell Hyde first brings him to court, he doesn't appear to notice the change in him as the conspiracy proceeds. A thoroughly mediocre young man.
