"The Occult", or "Nobody Knows"

[Helm]

Neither of the three you posted classifies as occult. Try something more in the lines of doing a web search on Rosa Crux, V.I.T.R.I.O.L or say, the black star in the sky.

I have some years of hobbist experience on such stuff and I can tell you right off that I think 99% is totally bulshit.
