City and Guild: Smugglers

And interesting option for Merchant adventures in City and Guild is Smuggling. The book says that smugglers have the Dark Secret Flaw (because they are criminals) and the Social Contacts Virtue (because of their network of clients and informers). I'd assume that a character created without either the Flaw or the Virtue can still turn to smuggling, automatically gaining them, right?

Gaining them over time more likely. How fast depending on how active you are.

Also gaining Enemies (page 53) and possibly Feud (page54) , if you are not careful.
Try smuggling saffron and see what happens.
At the very least , a couple of heavy-hitter magi from Venice may call to pay their respects.
