Most famously was when the cards were under the study of a man called Aleister Crowley, a member of the Golden Dawn, who created the Thoth Tarot Deck, which is still widely used today. Crowley, however, was said to be quite a strange man, who claimed to have invoked several Egyptian deities. Even more odd still, he later wrote about his experience summoning a demon and published a novel with instructions on Sex Magick during the early 1900’s in the United Kingdom.

Other than the twelfth house, the eighth house can be quite dark. This is the house where we find the sex- more specifically, BDSM, Sub/Dom, Fetishes, Low-key sexual “taboo” fantasies, sexual slavery and possession, etc. Although this is not the case for everyone (because all people are vastly different), but this happens to be where you’ll likely find it if it’s there!
