This is all as compliant with canon as I can make it, though there's obviously plenty of speculation or outright fiction mixed in there. Alert readers will notice that I've also incorporated elements of Hiywan's Story into the early history of the Council, as well as passing mentions of the original 'Buffy' movie and Season 8. If anyone wants to take my ideas and incorporate them into their own fiction, please feel free; or alternatively if you want to challenge my interpretation of the Council's history, you can do that too. (Historians disagree all the time on how to interpret the past.)

History of the Watchers Council
The Watchers' Council of Great Britain prides itself on being the oldest known human organisation in existence. It has changed its name several times, been all but destroyed and then re-founded at least twice, and many of its older records are long lost and crumbled to dust; but it can still trace a continuous thread of existence back over eight thousand years. There are, of course, demon cults and secret societies which are older - in some cases, a billion years older - but as far as humans go, the Council holds the laurel. This is their story.
