Think this through: imagine he goes to these orgies, and they film everything. That is already a basis for some blackmail. He is more or less describing Eyes Wide Shut.
But imagine a ritual where someone is killed, and all but ONE of them wear masks, and that, too, is filmed. All you have to do is get someone to do something they had not even planned to do, document a serious crime, and you have them by the balls.
It would seem obvious that any serious secret society has to have the power to get you jailed for life before they will even begin to share anything serious with you. This guy likely did not even scratch the surface. He is merely making informed guesses about the nature of the whole thing, and cannot begin to know how far it goes.
I do feel there is a spirit of this Earth. It is trapped here.
