Oh god. It's been weeks now, and I realized today that I've become the test subject. Instead of testing the social interactions between the locals and this group of rich assholes, it's just me trapped in here with them. They're going to live for ever, and I have to deal with them for the rest of my life.”— Overseer
Buried beneath the Cliff's Edge Hotel, Vault 118 was designed to function as an ultra elite hotel to attract test subjects of appropriate wealth and status. It was a clandestine area of the hotel to ensure that individuals drawn to privilege and exclusivity would be present. The original plan called for making the Vault open to the public when the Activation Notice was sent out (in the event of the Great War) and selected from the local working class population. These subjects would be taken through the exclusive areas of the vault on entry, but thereafter confined to cramped second wing. The Vault would remain sealed until test results could be determined.
The test group would include 10 ultra-rich, with every desire tended to by a robotic staff and placed above all legal restrictions in their interactions with the second group, numbering up to 300 people sequestered in uncomfortable, cramped conditions in the second wing. Any breach of ethics would be judged by the rich and any judgement enacted by the robotic staff. This classic bourgeois-worker set up was turned on its head when progress on construction of the second wing of the Vault completely stalled. Once the premiere area of the Vault was completed, funding was cut off. Ezra Parker, the key financier, simply pulled the plug, covering up with a story about troubles extracting payments from invited guests. Secondly, one of the subjects from Testing Group A (the rich) was a researcher for General Atomics on an advanced robotics program. He and his wife have convinced the other members of Group A that, with the international situation becoming tense, their best chance to outlast the war was to have their brains inserted into robobrains. When the Great War came around, the Vault was sealed. No outside persons were admitted, as the security protocols were taken over by the robobrains and the Overseer became the sole remaining human inside - the sole test subject in a Vault full of mad robobrains.
The Vault is accessed through an elevator in the exclusive section of the hotel. Once inside, Maxwell will open the doors and start Brain Dead. The Vault itself is opulent, in the style of King Midas. Expensive wooden panels cover the harsh steel and concrete of Vault-Tec infrastructure, with statues, decorative drapes, and furniture everywhere. The entrance splits off into a hallway leading deeper into the Vault and a passage into the giant underground parking lot serviced by the cog door on the surface.
Deeper in the Vault lies the ball room, where the late Ezra Parker lies. The right hand side of the area contains the living quarters of Keith McKinney and Gilda Broscoe, as well as the private museum and chamber of the late owner. The museum display cases are locked and can be opened, but contain only minor loot. Other display cases contain something more interesting, such as the pirate hat. Ezra's personal chamber contains the Vault 118 Overseer key, providing access to all the doors in the area. The only other room of note is the Classroom with a chemistry station.
Opposite wing contains the generator room (used by Santiago Avida as his work space) and the artist's living quarters. Opposite his area are Julianna Riggs and Bert Riggs, together with their pet cat and a hoarders' worth of furniture they plan to put in their mansion once the War blows over.
The upper level is a lot more decrepit and contains maintenance rooms, hydroponics, and the Overseer's office, where the investigation really picks off.
The main entrance to the vault outside the hotel is blocked, if the vault is throughly explored, they will find the unfinished sections for where the workers were to live, and a parking garage in the section of the main entrance, where the elite would park their cars, after they went through the entrance.
