Ooh, Ooh! I wanna play, I wanna play!
The Council of Arcturus, a small nation about the size of a medium sized clan, living on their own sovereign territory, New Camelot (I'm thinking either a large-ish plot of land in the middle of either Canada or the Outback [miles and miles of miles and miles] or an unassuming island in an archipelago, like the Solomon Islands or the Seychelles). Traditionally ruled by an oversight committee ("The knights") and head by a chairperson, The Lady of the Lake,("Lady") a title that was liberalized in the 80's to accommodate the first male recipient ("Lord") to collect enough political power to rule the council.
Politically, they are rabidly pro-human, and messianic to the nth degree, believing that one day the star will rise again and save the world from evil. Until such time, theirs is to shine, the brightest light in the dark until this time. Thus, seeing themselves as the true guardian's and protectors of mankind against all its predators, they get on imperfectly with the other pro-human factions, who they view as, at best, helpful amateurs including the White Council with whom they have an EPIC historic mistrust because of ancient blame for the absence of the star being shifted to Merlin (OG flavor).
Currently, strange rumors have begun to circulate in the clued in world of knights, seeming to be acting in ways contrary to humanities' interests, again allegedly because, "If humanity is to be saved, it must first be in some form of danger."
