Instead of personifying Bibracte, let's make her the Gallo-Roman diety Arduinna.

Nah, that's a bore.

I don't have any major problems. I've recently begun thinking about Unaffected by the Gift...
I'm not entirely convinced it's a Virtue, or at least see a way it could be disadvantageous to the owner of said Virtue.
Consider competing bargain rolls with someone with that virtue and a magus. Magus is going to get better deals, how is that good for the character with that virtue?
I can see other opposing social situations which become more advantageous for the magus, too.
I disagree. Let us look at it in the inverse. Say that being Unaffected by the Gift was the norm, and feeling the "bade vibe" was, say, a Minor Virtue. Would that make sence? At a cost of +1 Virtue point, you now can no longer judge a certain class of people fairly, and are automatically suspicious of them when they offer to help you?
Being unaffected by the Gift does not automatically make you friendly or well disposed towards magi. You just treat them like you would anyone else. And if you know they can work magic, you would act accordingly. Much like magi interact with each other.
