Re: Alternative Necromancy
I ran a PC necromancer once who, in a nutshell, had taken his ends-justify-the-means philosophy a little too far. Oddly, though, when I played him, I didn't really feel a lot of guilt about how he rolled. Any undead he animated, or summoned, were either soulless or coming from somewhere they didn't want to be anyway.
Incidentally necromancy is a fantastic special effect--you can use it for every single power in the book.
