Earldoms Of Gwynedd (fictional)
The Earldoms of Gwynedd are the second-largest feudal estates within the fictional Kingdom of Gwynedd in the Deryni novels of Katherine Kurtz. Each earldom is governed by a hereditary noble (an earl or countess) who rules their land in exchange for swearing fealty to the Crown. While earls and countesses enjoy the prestige and income of being in the ruling class of Gwyneddan society, they are required to pay appropriate taxes for their lands, see to the defense of their borders, and uphold the laws of the kingdom.
