East Coast

The East Coast, also known as the "Eastern Seaboard" or "Atlantic Seaboard," refers to the easternmost coastal states of the pre-War United States, which touch the Atlantic Ocean and stretch up to what used to be Canada. While in a strict 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.

Capital Wasteland
The Capital Wasteland is a large expanse of open areas with caves, Raider camps, etc. in the area of the former Washington, DC around the more urban areas of Downtown DC. As of 2277, the area is overrun by Super Mutants who are in a constant battle to push humans out.

The central hub of civilization in the ruins of the former capital is Rivet City, based in and around the remains of a beached aircraft carrier. Other settlements include the towns of Megaton, Springvale, Andale, Tenpenny Towers and Paradise Falls, as well as the Brotherhood of Steel Citadel built in place of the pre-War Pentagon. Movement between the certain areas is possible through the Washington Metro tunnels.

The Commonwealth
The Commonwealth is what is left of the pre-War state of Massachusetts. While it too was ravaged by the Great War and is as lawless and inhospitable as much of the former United States, its main attraction is the mysterious Institute. The Institute itself has developed highly advanced technology and even artificial intelligence, which it has used to create a population of subservient androids. An opposing organization in the Commonwealth, the Railroad, works to eventually free the enslaved androids from their creators.

The Pitt
The Pitt is a Raider settlement built from the decaying infrastructure of the city of Pittsburgh. The settlement is divided into two main areas: Downtown, where slaves work and live, and Uptown, where the raiders live. Downtown includes quarters for the slave population, The Mill, and the abandoned Steel Yard which is inhabited by Wildmen and Trogs. Uptown features the Abandoned Apartments and Haven building, the personal palace for The Pitt's leader, Ishmael Ashur. A network of ramps and bridges connects the upper floors of The Pitt's dilapidated buildings in both parts of the settlement, serving as platforms for raiders to oversee the working slaves.

Ronto
Little is known about Ronto, except that it likely consists of the remnants of the Canadian city of Toronto, and by 2277 had established itself as a notable power in the area with a reputation that reached as far as The Pitt.
