My lord Arthur and my friend Gwalchmai

I'll bet some of you are thinking, "Finally we actually encounter Arthur!" Yet, I wonder whether or not the Arthur found in my tale, Peredur the Son of Evrawc, meets your expectations. Does he live up to his reputation as Britain's greatest king? And what about Gwalchmai (a.ka. Gawain)? I can tell you that he is a very dear friend of mine . . .
