As a frontispiece for your Arthurian novels you show a map purporting to be England and Wales in the sixth(?) century. It shows Powys extending as far east as modern Leicester.Where does this map come from? I know that Powys at one time extended to modern Six Ashes, a village on the Shropshire/Staffs.border as this was the eastern limit of Wales as defined in the Tripartite Indenture between Owen Glyndwr,Percy and Mortimer, but this is a long way from Leicester!
