Damn awsome.
But I think you need to know what a necromancer is. Forget whatever you know, you probably got it all from Diablo 2 or something.
A necromancer is a person who uses the art of conjuring up the spirits of the dead for purposes of magically revealing the future.
And that definition is straight from the dictionary. I hope the author or any NG user reading this has a better understading now.
