Allow me to educate you then. Cabals are essentially special Inquisition taskforces geared towards dealing witha unique and persistent threat. Sometimes in certain cases the Imperium, or some part of it faces a threat that is large enough to be of concern to the Inquisition, but not broad or persistent enough a threat to need the creation of an Ordo. Thus usually at the behest of a Sector Conclave, or a High Conclave a Cabal is created. The Cabal is a group of inquisitors working toegether to monitor and counter the threat until such a time as the threat has been neutralized, or the danger it represents has passed.
