Bran, you know where Hugo's is as well. You might have even been in his "reception area" a few times, where he does business with those not part of his inner circle.

Night has come to Swift Rock Bay. The streets of the Wharf District have cleared of its daytime citizens, and shadows and alleyways are soon claimed by those ruled by vice and corruption. Prostitutes and pushers are the most common "business" people on the streets, but they employ (or are employed by) their own muscle to watch over their interests, and then there are the customers, some who take great effort not to be recognized, prowling from shadow to shadow in search of their next fix.
