Title: Fflewddur Fflam
Passage: Fflewddur Fflam, son of Godo, is a cantrev lord in the fictional country of Prydain in Lloyd Alexander's Chronicles of Prydain.  He is referred to as a King, but makes it perfectly clear that he is a very minor king of a tiny kingdom at best, much less important than the High King who is the ruler of Prydain.  His kingdom is described as being dreary and dull.  As a result, he often leaves it to go wandering about as the world's most unofficial bard in the mystical land of Prydain.  Though he returns from time to time to rule, he once mentions that he gets the feeling that the people of his country get along just fine even if he is not there.
