Well, her High Concept is right in the first post. Wiccan Sorceress. Like I said, it would have been Wiccan Wizard, but looking over the refresh costs of both Wizard and 'Faith' based Powers/Stunts, I couldn't have both in even a Submerged campaign.
Thinking on it with some of what's been posted has given me some ideas. For instance, the Wiccan Rede doesn't preclude self-defence (as most Wiccans understand it, anyway) but say it did.
There's still bindings that redirect force used upon them - Mirror shields, they're called - and if someone's silly enough to send an attack against them, and gets hurt, the usual view is that it was their action that caused the harm.
That, of course, would likely get her in trouble with the Laws of Magic, as well as the Wardens.
And, yes, the Rede allows for a lot of low-discipline behaviour, as long as it brings no direct harm to others.
So, thanks for all the replies. I'm only going to work her up to Stage two - saving the first Story until I can find a game for her, so her story fits in - but when I've got that done, I'll consider posting her, either here or in the PbP section.
