I don't believe necromancy falls under druidism. More like under voodoo.

Also the concept of witches under the guise of church people, though largely exaggerated, is not that far fetched. The Church did use pagan hollidays as base for it's own to better supplant the old practices. Christmas and Halloween being the two largest and internationally recognizable that I can offer as an example. I'm not sure as well about the larger scale of penetration though. A single Saint and profit here and there, maybe. Let's not forget Pope Joan, the female Pope. She certainly managed to penetrate way over to the top.

That's definitely arguable with categorizing necromancy, that's why it is, in and of itself, it's own branch of magic. Druidism does have aspects and ideologies of promoting life and survival, giving them spells of healing. Though they do believe in an afterlife, so pulling those that are already dead is a debatable topic. I apologize for placing it within the wrong category. Voodoo does revolve around more ritualistic, Native American spellcraft, even implementing spells to raise zombies(which is totally necromancy), but there is a blurred line between black magic and voodoo magic. In all honesty, pure necromancy falls under black magic, and possibly voodoo magic. Somewhere within that gray area.

While the idea of witch guised as a saint could be formed, I believe it'll just add confusion to the roleplay.
