Duke Stewart

Descendant of King Peter who founded Saint's Haven. Uncle of King Cassius III. Serves as an adviser to King Cassius III. Has some friction between him and General Duglas. Harbors deep-seeded jealousy knowing that the Knight-King Cassius is far more popular than King Peter and that his family is no longer the ruling family.

In Chapter 5: Guardian Gerrant, Duke Stewart wishes to honor Gerrant's contributions towards the kingdom of Cassius. He offers a Knight's Certificate to officiate Gerrant as a knight of Cassius. He also commissions Belin to craft an enormous statue of the Gold Dragon, much to Belin's dismay.
