The prosperous Kingdom of Daventry falls into ruin after King Edward, desperate to produce an heir, surrenders his kingdom's most precious magical artifacts to those who promise salvation—a sorcerer claims the Magic Mirror, a deceitful dwarf obtains the King's Shield, and a witch disguised as Princess Dahlia steals the infinitely generous Magic Chest. As famine, plague, and invasion ravage the land, the aging king recognizes in his most trusted knight, Sir Graham, the very image of the son he once believed the Magic Mirror had shown him, and offers him the throne itself on one final condition: retrieve the three stolen treasures and restore Daventry to its former glory.
