As most powerful occultist. It's very intriguing. But there is very little of actual symbolism here, besides robes.
From incorrect interpretation and superficial this would make more sense. Since in some dumb traditions of especially devil worship, head priest is supposed to be dressed in red and all disciples in black. Also anything Christian is supposed to be in reverse. Only thing that makes sense in both true occult and sort of fake edgy devil worship. Is the fucking. Fucking is power, robots.
I heard that there is something cut off from film and it would make much sense if that was the case.
