The Island

The Island (formerly Mount Desert Island) is a location within New England Commonwealth, and is the setting of Far Harbor.

Background
Before the Great War, the island was a famous holiday location. After the war, there were small settlements all over the island, however a radioactive fog drove the locals away. In 2287, Far Harbor and Acadia are the only inhabitable settlements on the island for humans. Dependent on player actions, other settlements such as Dalton farm, National Park Visitor's Center, and Echo Lake Lumber can be established. The cult of the Children of Atom has also established a stronghold on the island, based within a pre-war submarine base, called The Nucleus. These religious fanatics worship the Fog and at the time of the Sole Survivor arriving on the island are at increasing tension with the humans of Far Harbor.

Layout
The Island can be reached from the Commonwealth mainland via boat during the Far from Home quest, which can be begun in Diamond City at Nick Valentine's detective agency.

The island itself is quite large and features over 45 marked locations. The climate is cold and wet, dark and dreary, accented by rolling pockets of radioactive fog and frequent radioactive thunderstorms amongst rugged terrain and menacing woods.

The Sole Survivor arrives in the island's last remaining real human settlement, Far Harbor, which is located on the far eastern coast of the island.

The island is also home to a group of escaped synth refugees based in a pre-war observatory on a mountaintop, called Acadia, towards the center of the island.

Another major faction on the island is the religious cult of the Children of Atom. Their headquarters is a pre-war nuclear submarine base called The Nucleus, which is southwest of Acadia, off an inlet into the central part of the island.

The island also features a few pre-war factories, a pre-war lumber mill, two hotels, some national park grounds and camps, a drive-in movie theater, a bowling alley, an oceanarium and a variety of dilapidated pre-war houses and structures, many of which are now inhabited by gangs of Trappers (raiders) or super mutants, in addition to feral ghouls and various irradiated creatures.

A semi-completed Vault-Tec vault, Vault 118 is located beneath/within the Cliff's Edge Hotel, just north of Acadia and can be accessed as part of the Brain Dead quest.

There is Brooke's Head Lighthouse on the southern coast of the island, which features prominently on the picture promoting the Far Harbor DLC.

Towards the center of the island is the wreckage of Horizon Flight 1207, presumed to have crashed there during the War.

There are many wrecked boats, wrecked ships and smaller islands dotting the coastline of the main island. Some of these are inhabited by creatures, trappers, or other factions, while others are uninhabited.

Instead of Nuka Cola, the residents of the island even before the war preferred their own locally-produced soda brand, known as Vim!, which can be purchased in Far Harbor and found throughout the island. There remains a Vim! Pop factory on the southern part of the island where the beverage was produced prior to the war, now inhabited by super mutants.

Appearances
The Island appears only in the Fallout 4 add-on, Far Harbor.
