Arthur Pendragon

Arthur Pendragon, or simply King Arthur, was the king of Camelot and was the wielder of the legendary sword Excalibur. He is also the son of King Uther Pendragon and was mentored by the wizard Merlin. In his time, he formed the Knights of the Round Table and formed the Old Code, which has been followed for many years until it was eventually forgotten by many people, with the exception of a few like Gareth and Sir Bowen as well as the dragon Drago. After his death, Arthur was buried in Avalon with the rest of his fellow knights in a round circle just like the round table where they remained undisturbed for years.

While Bowen was alone in Avalon, since he wanted to stay behind while the others go to persuade the villagers to revolt against Einon, King Arthur appeared to him in a vision and reminded him of his knightly honor by reciting the Old Code. Soon after, the vision ceased and Arthur vanished.
