I'm somewhat new to the world of Warhammer, and I start my campaign on Sunday. The players have decided to go with something a little unusual for them - non-epic, and morally gray. After throwing a few ideas at them, they like the idea of *cough* "Breaking Bad-Hammer". A group of poor citizens who - out of need - embrace a life of crime, and learn the hard way it's not easy. I see it also with a heavy mixture of The Sopranos, in that they'll join (and take over?) a family of mobsters - ok, ok, thieves.
Is there a city that matches this? Obviously I can adapt any city, but I'm hoping for as little change from standard WFRP as possible. I'm somewhat trying to avoid (for now) Altdorf. But I need a city that is almost as large, with a corrupt or lazy Watch (and can I also add that the Skaven are involved?).
Any ideas or suggestions?
