King Arthur is the king of Carlyle. He is laid back and just takes everything for granted.
He is not characterized as a very good king, because he does not face his own predicaments forcefully.
He allows Sir Gawain to take on his responsibility. As shown in the story, it is Sir Gawain
who has to marry Dame Ragnell in order to save King Arthur's life. If Sir Gawain had refused to "marry the devil," King Arthur
would have lost his life and the battle with Sir Gromer.
