Tranquility Lane simulation

The Tranquility Lane simulation is the current active program of a Vault-Tec simulation created by Stanislaus Braun, located within the tranquility loungers in Vault 112.

Background
Construction started in November 2068, and finished in June 2074. It was designed to accommodate only 85 occupants, who would be suspended in a virtual reality world for the indefinite duration of the vault's experiment. The simulator was designed by Dr. Stanislaus Braun, inventor of the Garden of Eden Creation Kit, and initially contained several simulated utopias. The system should have permitted a select few to live a "perfect life" virtually, if not practically, forever.

What Vault 112's occupants didn't know was that once they entered the virtual reality pods, Braun would exercise complete control over the simulation; they had no means of leaving on their own. They became his playthings, completely at his mercy. Dr. Braun, after becoming bored with various simulated worlds, would proceed to virtually "kill" each one of them. When he finished "killing" the vault's population, he would wipe their memory, resurrect them within the next simulation, and proceed to murder them yet again.

Braun went through several simulations prior to initiating Tranquility Lane. The simulation reminded him of his hometown of Kronach but was distinctly American. Braun's subjects were naturally at home and felt safe in this environment, which made it more satisfying for him when he tormented them and shattered the peace of suburban life. By the time the Lone Wanderer came upon Vault 112, the simulation had been going for at least several decades.

Residents

Appearances
The Tranquility Lane simulation appears only in Fallout 3. It also appears on the screen inside of the flight simulation pods in Nellis Air Force Base in Fallout: New Vegas and is mentioned in a cut ending for the add-on Old World Blues.

Bugs
Before entering the vault, it is recommended to instruct your followers to wait inside Smith Casey's Garage and save the game because it's possible that one (or more?) of the followers (e.g. Charon) may disappear after leaving Vault 112 or the Tranquility Lane simulation. If the companions enter the Vault with the Lone Wanderer, they may automatically be fired. It may take a long time for them to reappear.
