Enclave

The Enclave is a remnant of the United States pre-War government.

Background
The Enclave was comprised of members of the government, Joint Chiefs, and successful scientists. Research initiatives of the entity included those centered on rocketry and energy weapon prototypes. During the Resource Wars, members of the Enclave made contingency plans in case of nuclear war, included securing installations such as the presidential oil rig and congressional bunker. In March 2077, the president of the United States retreated to the oil rig, resulting in news outlets such as the Boston Bugle reporting the action "giving credence to the long-running rumors of a secret, militarized shadow government, known as the Enclave."

The Enclave supported its own armed forces, known as the Department of the Army. The army utilized militarized robots alongside soldiers, including Mister Gutsy units, and sentry bots, and assaultrons. Specialized units such as the Secret Service and Squad Sigma were tasked with protecting specific Enclave initiatives. Artillery strikes were authorized by Enclave High Command.

Appalachia
On October 23, 2077, the Great War occurred, and some government officials made it successfully to the Appalachian bunker. Those who were members of the Enclave were allowed entrance and those who were not were killed. The military locked Enclave members out of their systems, and the bunker was unable to reach Raven Rock or Poseidon locations by radio. Without the ability to contact the president or Raven Rock, the leadership of the Appalachian Enclave fell to the Secretary of Agriculture Thomas Eckhart after the death of the Secretaries of the Interior and Treasury.

Eckhart assumed the office and title of president and set about facilitating his goal of launching a retaliatory strike by way of Appalachia's automated nuclear missile silos. This required an effort to manufacture a threat significant enough outside of the bunker to meet threshold requirements of the automated system. A variety of research endeavors followed, ranging from utilizing robots to manipulating diseases processes, creating and unleashing creatures such as super mutants and scorchbeasts. Dissenting views of other Enclave personnel resulted in a struggle, ultimately resulting in several deaths, extensive damage to the bunker, and the end of the Appalachian Enclave.

MODUS, an artificial intelligence, continued to maintain the facilities of the Whitespring bunker and coordinate surveillance operations on behalf of the defunct group. The facilities control the Kovac-Muldoon Platform support satellite and missiles. Information regarding X-01 power armor and mutation research is also found within the bunker, further explained by MODUS.

West Coast
Led by President Dick Richardson and Vice President Daniel Bird, the Enclave contingent on the West Coast of the former United States established facilities in addition to the oil rig, such as the Camp Navarro military base. With a limited range, vertibirds were able to refuel at the isolated Navarro location. Enclave Control Company maintained perimeter defense of the facility. Additional outposts were located throughout the former state of California.

Contact with vaults was made over a governmental Vault-Tec radio frequency, utilized to negotiate for access to the facilities and data stores. President Richardson indicated that these vaults served as "sanctuaries" so that "the glorious American civilization" would endure but also engaged in social experimentation. The oil rig location was powered by a Vault-Tec uranium nuclear reactor, overseen by the Enclave's Atomic Energy Commission.

Those operating on the oil rig developed their own goals, including the elimination of a "mutant threat" by way of murdering non-Enclave inhabitants on the mainland. Considering cohabitating with wastelanders untenable, the West Coast Enclave focused its research efforts on "cleansing the mutants" in order for "true humans, and democracy, to be safe." The group procured a sample of a toxin known as the Forced Evolutionary Virus from the Mariposa Military Base. Through subsequent research efforts, Enclave scientists were able to modify it into a more toxic aerosol pathogen known as FEV Curling-13. The virus and antidote were tested on the inhabitants of Arroyo and Vault 13.

The initiative was successful and preparations were made to release the toxin, the potential victims referred to by the president as an "unfortunate footnote in the continuing history of the human race." Before the deployment took place, the oil rig was destroyed. In response, the Enclave's command structure fell apart, and the New California Republic forces destroyed the Navarro base, stating that it posed a threat to the region. Enclave members who survived fled and attempted to integrate elsewhere, persistently hunted by NCR and Brotherhood of Steel forces.

A small contingent of survivors known as the Enclave remnants escaped to the Mojave Wasteland and settled after the dissolution of their group. They have access to a bunker that was previously utilized as a refueling station for vertibirds, now housing armor that was stashed years ago. The password required to enter the bunker is in the form of five words, one of which each remnant member has, equating to "Dear Old Friends Remember Navarro." Arcade Gannon is the son of a late Enclave officer who also resettled in the region, since keeping a low profile to avoid detection.

East Coast
The Enclave forces on the eastern seaboard were focused in locations such as the Adams Air Force Base and Raven Rock. Following the fall of the Enclave on the west coast, President John Henry Eden took office, next in the line of succession. Under his leadership, patrols monitor civilian behavior through a system of checkpoints. President Eden can be heard broadcasting on Enclave Radio throughout the region.

Several divisions of the Department of the Army's Field Operations Sector engaged in research initiatives. The Research and Development division collected samples from nearby craters and conducted experiments on technology such as Rho ID chips. The Peacekeeping and Recovery operations involved census records and weapons inventory. Fauna Detail Charlie conducted research on the effects of domestication units on captured wasteland creatures.

At Raven Rock, the president conducts operations with Colonel Autumn serving as their second in command. Their aims involved securing the Jefferson Memorial and the Project Purity water-purification initiative from the scientists within by force. This project was an effort to build and utilize the mechanism to purify millions of gallons of water at once for those living in the region. The colonel and president disagreed on the best course of action for the Enclave concerning the purifier. Colonel Autumn saw it as an opportunity to draw large numbers of people to the Enclave for "fresh water, protection, and a plan for the future." President Eden planned to utilize the project to spread a modified FEV toxin through the water, killing all mutated individuals and creatures upon ingestion.

At the Adams Air Force Base, research was conducted on projects focused on Duraframe Eyebots, Hellfire power armor, and deathclaws. The facility included the mobile base crawler, and orbital strike capability via the Bradley-Hercules satellite relay station. The Enclave has engaged in a series of conflicts against other factions, such as the Brotherhood of Steel, members of which refering to Enclave initiatives as "sinister," including dealing in advanced technology, drugs, weapons, and slaves. The citizens of the Capital Wasteland developed plans to take advantage of the ongoing conflict.

The Brotherhood attempted to both fight the Enclave while managing the water purification project, accomplishing this by attacking the airforce base, breaching the perimeter, resulting in Enclave High Command providing clearance to utilize artillery strikes. The Brotherhood was ultimately victorious against the Enclave at both the airforce base as well as Raven Rock, commenting that the sophistication and quantity of technology recovered is advanced.
