The Hellfire Club is a private establishment catering to the uber-rich, dating back several hundred years to pre-colonial Europe. It has branches around the globe, particularly in Manhattan and London. Most of the Club's everyday members are unaware of a secret cabal of power brokers among its elite, scheming for world domination and personal profit. This cabal was originally known as the Council of the Chosen before Sebastian Shaw overthrew the old order, forging the Inner Circle.
Other known members of the Hellfire Club include Dwayne Taylor, Norman Osborn, and Tony Stark.
