King Arthur Pendragon was a Briton leader who led the defense of Britain against the Saxon invaders in the early 6th century, and later became the king of Britain. He was also a member of the military organization that would come to be known as the Order of the Ancients.
Arthur possessed a sacred sword called Excalibur or Caliburn, one of the Swords of Eden, which he pulled from a stone. However, he was later betrayed by those he loved, which ultimately led to his death.
Alan Rikkin was of the opinion that Arthur's view of the Templars' role was idealistic and misguided, seeing his failure as proof that the Order was meant to follow a different path in the 21st century.
