Demonology

[CeaserJ]

What is it, and are demons, and the devil real? If they are, what kind of demons are there, and what is the nature of Lucifer? Are they summonable?

Interested in the invocations from the Grand grimoire, and Key of Solomon.

As I got no replies, I guess it was just a very vague question. Someone on other forum termed it as very broad, which i won't disagree with. Though if not about that question, i was hoping to get some knowledge on the two books I mentioned above. Knowledge as to the fact in the incantations, invocations and rituals present in them.

Fairly like, about the key (from Key of Solomon), and the virgin kid (In the Grand Grimoire). Those are some of the things I would love to get a pointed finger in a direction by someone. Can't find much myself, still searching for things like those.
