I believe a council sits above the 3 cities.
I'm fascinated to hear who or what you believe this is. I believe that there are many secret societies (as do you). I also believe that ultimately they all answer to one group. My research (rightly or wrongly) has led me to believe that one group controls the world. What we see happening around us it too organized and ubiquitous for it to be not the case.
Fascinating topic! I'm so glad that you took the time to put your thoughts and research into print. You've clearly done a lot of research, well done!
