Depends whose Merlin you read (did you read that stuff I sent you about the Guardian? I actually make comparisons with the Arthur story in that). Giles lives in Westbury, which is less than 30 miles away from Glastonbury Tor (where the Grail was allegedly hidden) and the flatland around it was supposed to be Avalon (I think). Giles in that daft wizard's costume reminded me of the Disney Merlin. In addition, Disney's Merlin is T.H White's Merlin and he lives backwards - which kinda fits with Giles being made a kid with an adult's memory. The rest of White's trilogy is much darker than Sword in the Stone. Mary Stewart's Merlin (for example) lived on Cader Idris in Wales (I think).I don't know what Merlin has to do with the watchers or their council. The Watchers are a symbol for the patriarchy. They are meant to teach the slayers an care about them in a patriarchal sense. They treat the slayers as children and assume (hope) they don't survive into adulthood. I believe King Arthur was male, so his relationship with Merlin is something completely different. I don't really know much about the story but I'd assume it's one man showing another what it means to be a man.
