Just found this(these) while browsing the deep web. Quite a lot of stuff. Magick 1, 2, 3, Occult Carrot etc. Also contains some stupid shit and non stupid shit.
Warning:
Also contains illegal material, and some other gray area material. You're not at any risk when viewing these, so feel free to do whatever the fuck you want. I don't care.
