When King Arthur saw the giant raise his bludgeon, he feared him mightily. He urged his horse with his spurs, and man and horse flew against him so hard and fast that they were all hurtled to the ground, the horses atop the men, but soon they had sprung back to their feet. But before King Arthur had picked up his arms, King Rion was back up and ready, for he was much quicker and more nimble; King Arthur was still only twenty-eight years old, but King Rion was at least forty-two and was bigger and stronger than he by a third.
