The Nucleus (formerly Mount Desert Island Naval Facility) is a pre-War submarine base owned by the United States Navy before the bombs fell. DiMA allowed the Church of the Children of Atom to utilize the place and, in return, protect his old memories from being accessed.


Mount Desert Island Naval Facility was a Submarine base owned by the U.S Navy before the bombs fell. At some point before the bombs fell, the USS Democracy and her captain, Arnold Wabash, had stopped inside the base to repair the sub for redeployment. When the bombs fell, Wabash did not want to be a part of the global destruction, so he sabotaged the ships reactor, which caused a radiation leak throughout the entire ship and base. After some time, DiMA found the old base, and decided to stay in it. After doing all that he did, DiMA decided to leave his memories in the control room of the facility. When the Children of Atom showed up, he and Martin made a deal where the children took over the base, but had to guard DiMAs memories.


The outside of the facility is built into the side of a mountain. It is made almost entirely of concrete.

Upon entry, there are two doors on the left that each lead to a locker room. If you continue down the hallway, you will arrive at the base. On the right is The Vessel, a pre-War submarine.

Continuing forward through a wooden shack, there is a wooden ramp up. If you go up, you will arrive at the shopfront of Sister Mai, and a little bit further is the shopfront of The Archemist. Turning left and going up the stairs leads to Brother Kane and a power armor station. Going further up the stairs will lead to the entrance to the Nucleus Command Center, guarded by a zealot.

Going straight from The Archemist's shopfront, there is a staircase that goes up on the right and a staircase that goes down on the left. The staircase on the right goes through multiple wooden shacks to end up at the entrance to The Vessel. The staircase down leads to Zealot Ware. From Zealot Ware, there is another staircase on the right that leads to the bottom of The Vessel, and a ramp up. The ramp up also leads to the entrance to The Vessel.
