SPOILER WARNING Based on what we know of the Cabal they are a race of hulking monstrosities that aren't too smart. Combat efficiency is one thing, but their social and just regular thought process seems to be lacking. The particular Cabal unit I wish to bring up is the Psyker. Excuse me if I am using the wrong name, but I think everyone understands what I'm talking about. They are weak and just a polar opposite of regular Cabal. Intelligence sky rockets and they seem to be social butterflies. The relationship between regular Cabal and the Psykers is what I'm thinking about currently. The two units obviously are used for different things, but seem to work well together in combat. The Cabal work under a Empire like system where their emperor must be on their home planet. So, under this system are the two looked at as equals, master and slave, or maybe some sort of peace treaty between species?
