The London offices of the Hellfire Club were featured during later issues of Excalibur's run during the whole Black Air storyline. Brian Braddock (Capt Britain) took his father's former seat on the inner circle in order to infiltrate the Club, at the request of Shinobi Shaw (Of all people) who had been unable to ascertain what was going on with the London Branch. As it turned out Bishop's former Nemesis Mountjoy had seized a position of power, and Black Air and the Hellfire Club turned out to effectively be one and the same as they tried to free a demon from its bonds deep below London.
However, my major memory of the London Branch was that whilst there were two sides to the inner circle Black and Red (they changed from white to distance themselves from there American branch) none of the inner circle members ever refered to each other by anything other than their Hellfire Club title of King, Queen, Bishop etc...
So who the hell were they?
I remember the Black Queen was a psychic who introduced herself to Brian as Ms Peel, and was seen conversing with Onslaught in one panel. I remember the Red Queen to have been Margali Svarsos (Spelling?) Nightcrawler's adoptive mother, and the Red King some distantly voodoo looking black mage, but I'm damned if I can remember if he was ever properly introduced.
What was the London Hellfire Club's roster back then, and providing they are still active, do they have a current roster?
