The East Coast, also known as the Eastern Seaboard or Atlantic Seaboard, refers to the easternmost states of the pre-War United States of America. While in a strictly geographical sense it includes the entire eastern seaboard, in popular usage the term "East Coast" is most often used to specifically refer to the northern half of this region, which is also known as the Northeastern U.S.
The East, much like the rest of post-War America, is a lawless wasteland. The Great War did not spare it in any way, although some areas were less devastated by the war than others, and so civilization has rebuilt to varying degrees across the East. While some major centres such as Pittsburgh and Washington, D.C. were heavily bombarded by nuclear ordnance, rural areas, such as in West Virginia and parts of Maryland, were mostly spared, though still subject to mutants and radioactive fallout. Other major cities were less heavily targeted, such as the Boston area which was hit by one nuclear bomb that struck to the south of Boston proper.

Adams Air Force Base
Adams Air Force Base was a major United States Air Force base before the Great War. Located just outside the Capital Wasteland, the base is accessible through the presidential metro, and in 2277 served as a secondary headquarters for the Enclave, supplementing their installation at Raven Rock. Enclave operations here were centered in the mobile base crawler, which had the satellite controls needed to call down orbital strikes on several locations in the Capital Wasteland. The base was captured by the Brotherhood of Steel in 2277, following the Lone Wanderer's destruction of the mobile base crawler.
The Brotherhood of Steel constructed the Prydwen over a period of several years at Adams Air Force Base, and maintain a strong presence at the base as of 2287.
The Broken Banks was one of several regions Tobar piloted the Duchess Gambit to, along with the Commonwealth and the Capital Wasteland. Nothing is known about it, except that it is located south of the Commonwealth.
The Capital Wasteland is the area surrounding the former city of Washington, D.C., including portions of the former District of Columbia, Maryland, and Virginia. As of 2277, the area is overrun by super mutants, raiders, mercenaries and numerous other dangers that threaten the small human and ghoul populations.
The central hub of civilization in the former capital's ruins is Rivet City, a settlement housed in the remains of a beached aircraft carrier. Other settlements include the towns of Megaton, Canterbury Commons, Andale, Tenpenny Tower, Paradise Falls and the Brotherhood of Steel Citadel within the ruins of the Pentagon. Movement through the ruins of the downtown Washington, D.C., area itself is facilitated by the remaining metro tunnels.
The Commonwealth consists of the remains of the pre-War state of Massachusetts. Like most other major population centers of the United States, it was ravaged by the Great War and is as lawless and inhospitable as the Capital Wasteland. Despite its anarchic nature, it is also home to the mysterious Institute, which has continued to develop advanced technology even after the massive amounts of destruction caused by the Great War. Among its accomplishments are artificial intelligence and androids, built as a servant class, with other models serving as trackers to return runaway androids. The Railroad, another organization within the Commonwealth, works against the Institute to free the enslaved androids. A militia by the name of the Minutemen helped to maintain order in the region until they suffered numerous setbacks and internal division leading to their near extinction.
Great Lanta is the birthplace of Saint Monica, who is venerated by the Church of Saint Monica aboard Rivet City in the Capital Wasteland. The exact location of Great Lanta is unknown, as it is only mentioned once in a sermon by Father Clifford, where he describes it as "on the shores of the ocean." Whether it's a real place or not is questionable, as Father Clifford's sermons are a modernized retelling of the life of the real world Saint Monica, who was born in the 3rd century in what is now Algeria.
Formerly Mount Desert Island, the Island is located off the coast of Maine. The Island has high radiation levels as it is blanketed by a radioactive fog which has mutated the local wildlife and driven many people exposed to it insane, who are known locally as Trappers. The Island is home to a secret colony of escaped synths, Acadia, the Church of the Children of Atom, and the native Harbormen.
The region of Point Lookout, Maryland was a largely rural area apart from a small seaside resort town named Pilgrim's Landing. Point Lookout was not directly hit by nuclear bombs during the Great War, but fallout from areas that were and lingering radiation in the waters of the Chesapeake Bay has had a significant impact on the area. The native wildlife has been heavily mutated, and the effects of radiation amplified by inbreeding has led to large amounts of deformities in the native swampfolk.
Located within the Eastern Commonwealth of the former United States, the region within the State of West Virginia was spared most of the destruction and carnage of the Great War due to its relative isolation and lack of strategic targets, but much of the surviving human population nonetheless perished over the following years due to the Scorched Plague. In 2102, the residents of Vault 76 emerged into Appalachia after twenty-five years of isolation and began to reclaim the wilderness.
At some point later, settlers from other parts of the post-war US would later trickle into the region, forming settlements and raider gangs.
Philly is the name given to the ruins of the pre-War city of Philadelphia. It is mentioned on terminal entries in Rivet City, as Abraham Washington's Capitol Preservation Society has funded an expedition to the ruined city to retrieve the Liberty Bell.
The Abbey of the Road
The Abbey of the Road is a Christian monastery, though its exact location is unknown. The Abbey's main concern is spreading the Christian faith, with the preservation of artifacts important to the faith being a secondary priority.
The Pitt is a raider settlement built upon what was the city of Pittsburgh, Pennsylvania. Pittsburgh was targeted with nuclear bombs during the Great War, and its location along the confluence of three rivers meant that it was not only subject to radiation from direct hits, but also the radioactive fallout that contaminated the rivers. The radiation, pre-War industrial pollution, and other contaminants mutated the population, creating a condition unique to the Pitt's immediate area known as Troglodyte Degeneration Contagion. In 2255, the Brotherhood of Steel decided to fight through the city in an event known as the Scourge that killed much of the Pitt's population at that time. This left a power vacuum in the city, which would be filled by a Brotherhood member, Ishmael Ashur. The Pitt had the only functional steel mill the Brotherhood had ever encountered, which Ashur aimed to use to restart the Pitt's industry. The Troglodyte Degeneration Contagion which plagued the city meant that children couldn't be born in the Pitt, and Ashur recruited raiders and bought in slave labor to run the city.
Little is known about Ronto, but some Pitt slaves are from the area. By 2277, Ronto had established itself as a regional power with a reputation that extended as far as the Pitt, as Ashur mentions the location in a speech.
- Tobar: "You should have seen her back in her heyday! Why, we travelled up and down the coast, from the Commonwealth to the Broken Banks."
- Lone Wanderer: "Where do you go?"
Quinn: "Oh, here and there and everywhere. I've explored all up and down the coast, from the Commonwealth, to the Pitt, all the way down to Crater Banks."
- Brand: "You're new, aren't you? Are you here from the Erie Stretch? The Capital Wasteland? Ronto? Where's home?"
- Lone Wanderer: "You got anything for me?"
Everett: "All the metal you're bringing in, I suppose it's worth giving you something to really help with those Trogs. Here, this thing's mauled Trogs and Ghouls from here to Monroeville. Give it a whirl."
