"In King's Quest III, the story moves away from Daventry and King Graham to the land of Llewdor, where a boy named Gwydion is being kept by the wicked wizard, Manannan. According to the introduction, for as long as he could remember, 17 year old Gwydion has been held captive by Manannan as his servant, cooking and cleaning for him in his home atop a large mountain in Llewdor. From this vantage point, and with the help of a telescope, the seemingly all-knowing wizard watches the countryside, with the shore to the east and the desert to the west."
