Besides battling against King Arthur, he also had someone by his side. A knight emerged at King Arthur's flank and retracted his blade. It was Sir Geraint, a knight from the roundtable. If I had to guess Sir Geraint, he may be a friend that King Arthur trusted.
"I shall lend you my strength and battle for your cause, my friend…..Am I allowed to join your battle, King Arthur?" Sir Geraint asked, while giving his body enhancement spells.
"You may, Sir Geraint. But leave Arthur and Merleen to me. You could attack that monster over there with that hideous fur."
Sir Geraint had a peculiar beard growing on his face, which described his ancient age. His armoured plate slowed his movements down, but enough to protect his skin. I even doubted that my Clarent would deal damage against that.
