Conglominatti
If the field of alternate timeline sociology teaches us anything, it teaches that there are three paths to big-c Conspiracies. There is the accretion path, in which one shadowy group takes over more and more other groups until it discovers, one day, that they’re the Secret Masters now, hooray!; there is the reorganizational path, where a shadowy group attempting accretion discovers that their Conspiracy has been taken over from the inside and/or parceled off into a number of half-independent factions inside the main structure, which then contest amongst themselves for power; and there is the amalgamation path, where various independent shadowy groups deliberately combine efforts to create a Conspiracy built up of sovereign, autonomous entities. That last sort is called a ‘Conglominatti’ by the more vulgar, and is discussed below.
