Sir Gwaine is a Knight of the Round Table and a good friend of Merlin. He is portrayed as a fun-loving, laidback, and highly loyal character, adamant in his belief that nobility should be defined by what a person does rather than who they are. As such, he is wholly dedicated to doing what he believes to be right, and though his introduction show him to be a rather reckless and carefree man who thinks about little more than ale and women, Arthur and Merlin soon discover that he respects honour and loyalty above all else.
