Speaking of Percival, some time ago, I was reading a book about the Grail legends which mentioned a medieval German Grail romance where the knights who guarded the Holy Grail for the Fisher King were sometimes sent out in secret to rule kingdoms whose thrones had become vacant, although under strict orders not to reveal that they came from the Grail Castle. Was this where you got the idea for the Fisher King heading the Illuminati? That behavior certainly sounds very proto-Illuminati-ish.
