That's likely the Afadjanni system - but it is pretty much a "top-down" thing. Most people caught up within the machination of it all likely just get on with their lives whilst acknowledging the structure of the Ompalam Cult. That said, if you are a slave on a plantation it is pretty hard to ignore the sheer nastiness of the system (i.e. become a PC).
Afadjann is with pout doubt one of he major areas of Glorantha that is really hardly explored, sadly so.
A campaign development of "Harrek's Saga" would be great!!!
