Earlier I said this was going to be TLJ of mods, but in retrospect I’ve thought of a better comparison. This is the Fallout 76 of mod launches.
The Enclave were made up of remnants (or the descendants thereof) of the United States government attempting to bring said government back into power. In the Fallout universe, the US government prior to the day the bombs fell was rapidly sliding into an authoritarian regime focused on brutal expansionism (Mexico and Canada had been annexed by force to claim natural resources), and The Enclave was created as a “continuation of government” contingency to bring about the restoration of the United States government by any means necessary, which over the course of Fallout 2/3 included mass murders (FO2), mass kidnappings (FO2), assassination of dissenting individuals (FO3), suppression of dissenting opinions (FO3), inhumane experimentation with FEV on both wildlife and humans (FO2), and general disregard for humanity in the face of their goal.
By the events of FO:NV, the Enclave had been all but eradicated between the Chosen One destroying their primary strongholds on the West Coast (Fallout 2) and the combined forces of the Lone Wanderer and the East Coast BoS waging war against the East Coast Enclave (Fallout 3); The Remnants in FO:NV are a shadow of the former Enclave and had fallen into obscurity, so you don’t see at that point in the timeline what they really stood for. In development terms, Obsidian didn’t want The Enclave to be a major player for the third Fallout in a row, so Ceasar’s Legion (roman wannabees) was introduced.
