The Great Sky Kingdom endured for about twenty four centuries, ca 100 to 1416. The mythical forebears of the Great Sky Kingdom were the Mipnors who claimed Myddarddowen as their legendary founder. The Parkyons migrated into Barathorn and settled in Dewyddair in the early 3rd century before Salmakhamer (227 to 225 AS). Thus there was a period of roughly three centuries before the beginning of the Great Sky Kingdom around 100 AI.
