Underworld

Underworld is a settlement in the Capital Wasteland in 2277. It was once an exhibit in the Museum of History before the bombs fell. Now it is home to many ostracized non-feral ghouls in Washington, D.C. It is located inside the Museum of History and exists as a small city, complete with a bar, inn, clinic, general store, and even a self-proclaimed "hair stylist".

Most humans are tolerated, as long as they don't cause trouble. The Brotherhood of Steel are not welcome because of their hostility towards ghouls and their tendency to shoot them on sight. The super mutants leave the ghouls alone.

Background
The Underworld ghouls are a group of refugees who have taken up residence in the remains of the Museum of American History. They mostly keep to themselves, doing their best not to draw attention from the outside world and its prejudices. They are known to welcome visitors, so long as those visitors behave themselves. But even as they welcome newcomers, the ghouls of Underworld are cautious and wary of strangers. Each was subject to abuses by humans in the past, and as a result, their trust is easily revoked.

Exterior
A ghoul named Willow patrols the exterior of the Museum of History. The entrance to Underworld is located within the Museum of History beneath a giant skull. A Brotherhood of Steel outpost is located nearby the museum, and there are super mutants across the road at The Mall.

If the Broken Steel add-on has been installed, Griffon will set up his Aqua Cura presentation outside after the quest "Take it Back!".

Interior
As the Lone Wanderer enters Underworld they will find Tulip's general store Underworld Outfitters on the left, Winthrop's office to the right in the back corner, and Doctor Barrows' laboratory/clinic, The Chop Shop, along the posterior wall. This is where the player character can meet Reilly, the founder of Reilly's Rangers, and start the quest Reilly's Rangers if the player character has not already done so.

Heading up either set of stairs will take the Lone Wanderer to the overlook. On the left is the The Ninth Circle, a bar run by a shady ghoul named Ahzrukhal. On the right is Carol's Place, where the player character can rent a room or grab a bite to eat. If the Lone Wanderer destroyed Megaton without first having finished the quest Wasteland Survival Guide, Moira Brown will be selling miscellaneous items in the large room at the end of the overlook. The Lone Wanderer may also resume helping her with the Wasteland Survival Guide by talking to her. Between the two upper level establishments there is Snowflake, the resident barber, who is desperate to work with "a full head of hair" and wants to give the player character a haircut.

Behind the scenes

 * The large ruined painting on the second floor of the concourse is "Dante and Virgil in Hell" by William-Adolphe Bouguereau.
 * Also relating to Dante and Virgil, the bar "Ninth Circle" is phrased after the travels of Dante and Virgil through the nine circles of hell in Inferno. The Ninth Circle is the final circle, where traitors including Lucifer himself reside.
 * Many of the inhabitants' names are related to the hell concept, including: Cerberus (Hades' 3-headed dog), Charon (the ferryman of the River Styx), and obviously nurse Graves and doctor Barrows who reside in the Chop Shop.
