@Art of Fun: Okay, I'm going to start with what I like about your bio. I like the idea of non-malevolent nercomancer and lich, to start with. There's nothing inherently evil about choosing a method of immortality that doesn't actually hurt anyone and there are applications of necromancy that are perfectly benevolent. I also think using an instructor at the Mage Academy could be pretty interesting.

That said, there are some problems. I'm going to start with pointing out that sapient undead would be immune to necromancy, at least insofar as controlling them goes. That's not so much of a problem though as much as something that needs pointing out. The problems are that, well... I guess this one is more a matter of opinion, but I'm not sure why becoming a lich would make such drastic alterations to your appearance. After all, wouldn't one of the advantages of being a lich be that your body doesn't change? I'd also think that if she didn't want to be seen as attached to the cult she'd probably try not to look so potentially evil. ^^;

As for the cult, I'm going to assume good faith and that they're not much more then any other criminal group, they're just doing it for reasons they believe are religious. That said, I really, really don't want any kind of central villainous group in this and I want to make sure that's not the intent. I also want to make sure they're not too powerful, as the Watch would actively be hunting them down any time they have a chance, though naturally it would be difficult given they hide in the catacombs.

@evilpooka: I'm sorry, but I think you're overestimating the technology in this setting a little bit. ^^; There is some steampunk, but it's mostly in airships and a small number of other things. I don't think it's advanced enough to do as much as you describe it doing. That said, it probably could be used to safely replace a limb, though it would need magical assistance so it doesn't harm the body it's attached to.
