Already devastated by the actions of the Lone Wanderer, and the Purifier's widespread contamination of the region's water supply with the forced evolutionary virus, the Scission, known to the rest of the Capital Wasteland as the destruction of the Citadel by tactical nuclear orbital bombardment, resulted in a power vacuum with the former two superpowers of the city, the Enclave and Lyon's Brotherhood of Steel, reduced to little more than a shadow of their former selves. Now, four years after the Purifier Conflict, factions new and old alike struggle for dominance in the irradiated capital of prewar America.
This is going to be a fairly casual role play, but expect to put in some degree of time and effort into posts, so they can pass a bare minimum of readability. Roleplayers can create or alter factions as they desire (primarily keep within the boundaries of the Capital Wasteland and terrestrial DLC locations), and I'm unlikely to outright deny any. However, keep in mind the power dynamics of the Capital Wasteland have changed drastically since the days of the Enclave and Lyon's Brotherhood of Steel. Hell, Megaton is nothing more than a smoking ruin nowadays. Generally, as a rule of thumb, expect that the Lone Wanderer chose every bad karma quest outcome, and that factions such as Talon Company, Rivet City, the Outcasts, will be roughly about as powerful as factions can be initially in this roleplay.
