Hi Jup, David, Opal and Leomoon,
I don't know all the answers, i don't and never have practiced alleged astrology magic, but have made a study of it in theory.
Many powerful people believe in it, that it helps their aims and purposes in the greater influence regarding the human race,
however these secret societies are not always joined and can be "opposites", working against each other, it is all very confusing as they all use Sirius and Alnilam in rituals, so it is hard to see who is who?
It may be as mild as The Fellowship of Isis formed on the Vernal Equinox, 21st March 1976 in Clonegall, Ireland, while Alnilam, Belt of Orion and Osiris star was setting:-

The more unsavoury secret societies do use the same stars, like the Illuminati secret society and the Nazi Party, how much influence they all have in changing history is open to debate regarding the rituals:-
