Underworld

Underworld is an area where many ostracized sapient ghouls (as opposed to their feral brethren) of Washington, DC live. It is located inside the Museum of History, and exists as a small city, complete with a bar, inn, clinic, and "stylist".

Most humans are tolerated, as long as they do not cause trouble. The Brotherhood of Steel are not welcome, however, as they tend to shoot ghouls on sight.

Background
The museum was featuring an exhibit on the mythology of Hell and the afterlife during the time of the Great War, as most of the remaining exhibits (including the name of that section of the Museum as well) are all themed as such.
