"Alright. Flush the bombers, get the subs in launch mode. We are at DEFCON 1."
Unless you've been hiding under a rock most of your life (and, to be fair, if that was the case I can guarantee you definitely know what I'm talking about), you've probably heard of Continuity of Government.
Continuity of Government (C.O.G.) is the planning and preparation for how government can continue after a catastrophe, like a nuclear war or asteroid strike or Cthulhu waking up. Among the most important parts, beside laying out a list of contingencies and picking a Designated Survivor to sit out all the public events in case a bomb goes off, is building bunkers to hide in until the radiation levels drop enough for a go at repopulating the Earth.
Obviously, the government's not just going to let any Tom, Dick or Harry into those super-special-secret bunkers they've built though. Nope; only the lucky few, the most important, cleverest, bestest people are at the top of that list. Oddly enough, the guys who drew up the list - namely the politicians - seem to think politicians are the most important, cleverest, bestest people for the job.
Whatever the case, there are a lot of those bunkers. Most were built a long time ago, back during the Cold War. A lot are just sitting there. Unmanned. Untouched. Unused. Safe. Secure.
Now home to other things.
This is an underworld C.O.G. chamber for Esoteric Enterprises.
