I'm getting ready to run this in a few months, and looking through the section on Port Peril I'm worried. The PCs are very anti-slavery (or at least the captain is), and I have a feeling they might try to take down Saltfish Camp. I'm not sure exactly how difficult to make it (besides, y'know, very) but I'm more concerned about how the rest of the city would react, and given the rest of the plotline, never showing their faces again doesn't sound like the best option.
Any ideas?
