The Millennium Club is a well-known and exclusive private club for movers and shakers in the city -- and it's also a front for the New Hellfire Club, which is a rather . . . decadent . . . organization; and in turn, the New Hellfire Club is a front for the Council for Defense, an organization of benevolent supernaturals.  (Note: Every supernatural that "Mr Grey" trusts is invited to become a member of the club.)<br/><br/>The Club has an imposing granite edifice downtown, looking like a bank or a government office. There are two bouncers in tuxedos at the door, as well as a doorman (who is also a trained bouncer) and a butler who checks every arrival against the guest list.  Anyone who is not a member or employee is taken to the waiting room off the hallway just inside the door, and must wait until a member arrives to escort them.<br/><br/>The top level of the club is reserved for members' private rooms, and for storage.  It's decorated like a British gentlemen's club from a century ago.<br/>Next is the ground floor, which has the waiting room, meeting rooms, and general club rooms where the members sit around in overstuffed armchairs and harrumph about the state of the modern world with motor-cars and wireless. The ground floor also has a dining hall (almost never used) and of course the waiting room.<br/><br/>Below ground level looks like a Las Vegas nightclub from the 1950's, with many small tables and booths. Larger tables can be brought out to accomodate larger parties.<br/><br/>An astute observer would notice several unusual things about the nightclub area.<br/><br/>The walls of the nightclub have several balconies on them, with private booths.  These are balconies for private parties, which can be reached either from the floor of the nightclub or from the upper floors.<br/><br/>There are also fixtures along the walls, and several places on the floor of the club, where things can be attached, such as . . . chains or manacles.
