I highly recommend Liber Null by Peter Carroll. It's often sold as a 2 for 1 with Psychonaut included, and I wouldn't necessarily recommend Psychonaut unless you're interested in Entheogens in relation to spirituality. Although, I prefer Carroll's take to the more common "stoned ape theory". Liber Null may be slightly dated in it's technological references when it comes to a younger audience (such a references to VHS or Cassette tapes), as it is not a new book. It has extremely valuable information that could be used by the average person, experienced magickians, graphic artists, theoretical scientists, and shit posters alike. It is easy to read, and can be applied in almost any school of thought. What you do with that information is up to you, and I can certainly say that Chaos Magic isn't something that relates to type alignments in tabletop games. If you're looking for that sort of thing and any genuine connections to modern day sorcery, I recommend looking into older TSR versions of D&D and their unique Monster Manuals (Like Deities & Demigods) followed the works H.P. Lovecraft & other early authors Cthulhu Mythos. Even LaVey dropped a few references to Lovecraftian texts as a source of inspiration, but there are genuine Cultists that revere the beings described by Lovecraft & his contemporaries for their own reasons (which I'm sure LaVey would not enjoy as much, compared to the symbolic rituals and epicurean lifestyle he promoted, which isn't necessarily compatible in many cases).
