The Mechanist's Lair

The Mechanist's lair is a location and settlement that appears in the Fallout 4 add-on, Automatron.

Location
The Mechanist's lair is located slightly north of the East Boston Preparatory School. It is behind a building that is unmarked, and near a warehouse that is by a bridge, and a small wharf. Upon completion of the DLC, it is a new player home

Background
The Mechanist's Lair was originally a RobCo sales and service center which sold terminals. Employees of the service center were told specifically not to interact with any abnormal crates, or else they would be "taken to see our friends below." In a storage room for the center, a large door which requires an M-SAT to enter leads into a large underground General Atomics base used for the construction of robobrains. It functioned as a pseudo-prison which housed prisoners, who were later operated upon to remove their brains. After wiping their brain of memories and passing assorted tests, the brains would then be housed in a robobrain head and mounted to any of a number of devices, including the bodies of a normal robobrain, controlling stretchers, or even controlling operations inside the control center.

Sometime before the events of Automatron, Isabel Cruz discovered the facility while scavenging and took it upon herself to use it to create an army of robots to save The Commonwealth from anything which may hazard humans.
