Circle of Eight
Also known as Mordenkainen’s Circle of Eight, this was a Fellowship of Powerful Wizards working to protect the city of Greyhawk from destruction. The Circle was founded in by Mordenkainen. The exact make-up of the eight has changed over time and has continued to remain somewhat of a secret to the general populace of the Flanaess. At one time, each of the Circle ruled over one of the Eight Kingdoms.
