The parable of King Arthur dropped on the show display. Uthur Pendragon is given the magical sword Excalibur by Merlyn. At his demise Uthur buries the sword proper right into a stone, and the next man that will pull it out shall be King of England. Years later Arthur, Uthur’s bastard son attracts Excalibur and turns into king. Arthur’s evil half-sister Morgana sires a son with him, who would possibly present his downfall.
