True. So that would lend itself more towards a Lord Raith/Adrianna alliance, which might not have been completely mutual. I've been looking at several of the early plots, and they all seem to revolve around removing Marcone from power, thus enabling other factions to try and increase their influence in Chicago.
Maybe Harry's continual interference has kept the Circle unified longer than they would have been, had they not had a common enemy/pest.
Yeah, I suspect that Harry may be more
forming a Black Council as he goes along, as a counter-reaction, rather than opposing something that already existed. Just like Martin described how the Red Court would collapse in massive infighting after every White Council victory, I imagine any organization filled up with as many Black Hats as Harry suspects to be in the Black Council would have a similar degree of internal division.
It's hard to say more than that there's some loose alliance of supernatural oldsters who are sick of the modern mortal order and want to do away with it for one reason or another, ranging from the various attempts to push Marcone out of Chicago to Aurora's insanity (did something drive her insane?) to Cowl and Kumori wanting to abolish death to more speculative goals (like my suspicion that Mavra wants to resurrect the elders of the black court; who the hell knows what Peabody wanted).
We know that there's something Cowl referred to as "the Circle", but that could mean anything from a literal organized Evil White Council to the evil-magic equivalent of an IRC chat channel.
