Coastal Commonwealth
Once a vacation destination, as well as a destination for military and commercial interests. Salem, Nahant and Revere Beach lay on the shore, mostly abandoned due to a combination of raiders, feral ghouls and super mutants camped out at Revere satellite array.
SALEM
Once a quaint coastal town and seaport, Salem was turned into a tourist destination by the infamous witch trials of 1692. After the Great War, the town's residents worked together to make it a secure settlement, and over the next two centuries became known as one of the safest towns in the Commonwealth. As a consequence, the townspeople grew lax in their defenses, and about a century ago the town was wiped out by mirelurks.
Since mostly abandoned, the area has become mostly avoided by wastelanders due to Gunner activity, the Church of the Children of Atom worshipping at a nearby radioactive crater, and the large number of mating mirelurks in the waters all around the bay.
NAHANT
Located on a small peninsula to the northeast of the Commonwealth and surrounded by ocean, Nahant boasts high security with only one major line of entry - a thin land bridge from the northwest of the landmass. Once settled by remnants of the Commonwealth Minutemen, the inhabitants have since devolved into a group of raiders, and the area is now mostly avoided by the majority of wastelanders.
