| A master of dream-manipulation.|
As a young child, a plan came to him in a vivid dream where he saw himself running a successful business from a great structure. He told his father about it, who laughed and said he should be a banker like his ancestors. He refused and wanted to find out what that dream meant, so he studied to find out more about Magic, particularly oneiromancy and dream interpretation. Once he had learned enough, he left Lunar Isle attempting to find the location where he built the huge tower. Since he had not found it or gathered enough money for its construction, he decided to set up a small business north of Yanille selling dreams to people, which became known to the people as the Nightmare Zone.
