I view necromancy in the same way I view fortune telling: literally callin forth the dead isn't real, but there are a lot of people in the world who believe in it - especially RHPers who are supposed to shun the black arts. I come from a very Catholic family and most of the women in my family believe in some form of divination; they are fans of John Edwards and tarot cards, etc. As a result, I, personally, view these dark arts as powerful manipulative tools which lie between Lesser Magic and Greater Magic.
Despite being mere parlor tricks, with the right people seeking out fortunes or séances and the right amount of knowledge you could likely easily manipulate people to get what you want out of them by convincing them of your power.
Is any of this making sense or am I talking out of my ass?
I think it could be fun to learn the tactics and play with people. What do you guys think about this?
(I apologize if this seems insulting. The more I read the posts, the more it seems you are interested in literal, theistic necromancy and I am not intending to insult your beliefs. I was just stating some thoughts I had on the subject.)
Although, I can see a form of necromancy being invoked in ritual, say, as opposed to "summoning demonic influences" one could "summon the sprits (not literal spirits, obviously) of the dead" in a form of 'ancestor worship' I guess; ancestral influence over a magical working.
