You mean necromancer as in someone who raises dead spirits and animates corpses right? I am an aspiring necromancer in that aspect. But I don't think one should use necromancy for evil, or too much.Only to get information and to save lives.
Not accepting someone comes from nothing else than from lack of understanding and knowledge. Necromancy is not bad. Even death itself is not "bad". You must never care about what others think, if it feels right for you, and you feel good doing it, than do it.
OpenEyes, I've had the same problem.. Almost exact same problem.. Only thing is, I started telling them (hard-core Catholics, none the less) that I was seeing demons. I'd get used to certain spirits being around.. But there were other, darker ones (as you described the little girl). I started to associate them with the archetypal demon, and then I got stuck in counselling for about a year..
But, I guess i had good luck. ^_^ One of the counselors is also pagan, and understood exactly where I was coming from.
I guess the point is, don't give up, do your research, and keep yourself safe.
(PS: I was talking about Necromancy as in the "Talking to the shades of the dead" aspect, and though I personally find raising corpses morally wrong, I know it requires a lot of energy.. And that energy has to come from somewhere, hopefully not you, 'cause to bring back the dead, you need to provide enough energy to sustain and restart life.. Basic physics: Any action has an equal and opposite reaction. If you have the action (death), than the equal and opposite would be life, meaning it might cost you your life.
And I personally don't think that the Earth would provide the energy for that.. It just got their energy and turned it back out to a new life. There's only a few options as I see it: The Universe (BIG store of energy, if you can access it.) Demons (Could have negative repercussions) Divine Intervention (If it happens, than maybe the person wasn't supposed to be dead after all...)
Anyway, I don't mean to discourage.. Just be careful and study before doing anything serious.
I did read up about it once and all it said was tha it was comunicating with the dead and harming others. It even said that the heling spells took as much health from one person as you healedanother. (Example) If you managed to heal someone near death someone elses healht would be taken putting them near death. I quit reading after part of it becouse I'd seen enough to know that that is not something I would want to do. So from that I would most indefenently say that if unless you enjoy harming people and disturbing the dead you shouldnt do it.
Magick as I see it is simply a tool manipulated by the caster. Example is a hammer which is useful in construction work but also a good blunt force weapon. The only thing that makes a spell bad is the moral standards the one judging it has.
Necromancy involves talking to older spirits which have lived in the physical plane and experienced death. They have yet to come back so they retain all knowledge they have gained over their life span. I always saw the dead and it doesn't bother me to talk with them either as a corpse or whole human.
