Origins/Major Influence: Sweep of Unhistory (Paranoia Mission)
Description: This Complex, based in the Caribbean or Oceania, blamed advanced technology for the global die-off and has responded accordingly, outlawing technology for all but the most "trusted" of individuals (the VIOLETs and ULTRAVIOLETs). INFRAREDs are not even allowed to use of fire and make "primitive tools", that's limited to RED clearance. If you get promoted upwards in clearance, you gain access to more and more technology, until you get to Complexian-levels by ULTRAVIOLET clearance.
Each island is ruled by a ULTRAVIOLET and his closest flunkies, who are made effectively immortal thanks to sole access and control of cloning technology. Everyone else reproduce and die "normally". Most people live in normal cities or villages and toils for the good of the ULTRAVIOLET leader, while the ULTRAVIOLET and his flunkies live in a spacious villa.
The Computer here is incredibly decentralized: "a trillion-strong swarm of networked wasps". It is only focused on two thing: ensuring communication between the different islands and ULTRAVIOLETs, and to keep watch against any potential dissenters against the regime. Only ULTRAVIOLETs are allowed to travel from island to island, making some people speculate that perhaps there is no actual Complex, just an insane UV in control of an insane Computer. That's not exactly true: The Computer is in fact fully independent and autonomous, because the knowledge of Computer Programming was outlawed for all clearances, including ULTRAVIOLET. This makes The Computer a formidable force, something that not even the UVs want to tangle against. There has been rumors of entire populations being wiped out because The Computer has determined the entire island as a threat against the security of the Complex.
The Computer does not handle promotions though, only the ULTRAVIOLETs. Realistically however, the highest a person can get promoted to is VIOLET clearance, as ULTRAVIOLETs are immortal (at least until the cloning tanks are disabled, then a VIOLET could seize an island by force and then get formally recognized by the other ULTRAVIOLETs).
Spy From Another Alpha Complex: The limitations on technology tend to put a hamper on the prosperity of the complex. Loyalty to a ULTRAVIOLET does not translate to knowing how to operate a toaster effectively, much less actually inventing new stuff or repairing all the old stuff. This complex therefore requires the use of spies to ensure its continued existence, though spies tend to be of high clearance and given special UV brevets to actually know all this technology they're stealing.
