Black magick without demons?

[lumineth Realm Lord]

Besides the HP Lovecraft cosmic horror stuff, I was wondering if there are any other forms of black magick that doesn't actually involve demons of the goatia

It depends on your definition of a demon. I have a few classic Grimiores that let you summon planetary spirits for purposes akin to black magick. They don't involve your classic Goetia spirits or traditional named demons, if that's what you're asking about.

Create your own system I never understood why people use already formed one that are dead ends...
