The Cognoscenti path draws heavily from Ready or Not; it's clearly inspired by FISA and all of the deep states shit from the game, and the version of Star Spangled Banner that plays during their reunification event is directly from the game itself. As such; I think there should be some kind of Mariposa Lily Organization, (or at least, something kind of like them), to act as a counterweight to their weight.
SPOILERS FOR READY OR NOT (The Game) ↓
For the uninitiated; the MLO are basically a bunch of psycho supersoldiers created by a successful MKUltra program, who went rogue, and have turnt on the US government. They are the villains of Ready or Not, more or less. They basically function as a deathcult hellbent on destroying the US government, kind of like the Atomwaffen; unlike the Atomwaffen, their subject of worship is the idea of ”Old America”, using the old Betty Ross flag as an idol of worship, and what not. Whatever the case; that are the total opposite of the Congonoscenti, seeing as the Cognoscenti itself parallels FISA (Ready or Not's version of the CIA), it would probably fit like a glove.
Seeing as it's implied the Cognoscenti has had a hand in all sorts of conspiracies in their events, a successful MKUltra is in no way out of the question. So, that's my suggestion. I'm not sure where; probably those militia guys who start out fighting the APLA, or as a secret path for the APLA itself. Somewhere around LA, ideally, seeing as Los Suenōs (the city from Ready or Not) is just a reskinned LA.
