I think this would be a good time to bring in the character's possible contacts.
Quinn might have pirate, buccaneer, and other sea-dog types that might have been rich enough to attend the Pleasure Dome after a good haul.
Hilmdyn may know a priest from his sect who has given counsel to someone in the city disturbed with what he had seen there and talked about it in detail in a confession.
Edvan may have heard from a rich merchant he has hauled equipment from the docks about the place. Or Erin might even know something if Edvan wants to see if her can locate him.
Most likely, Lola and Rovan will have the most important chances for contacts because of their backstories. Lola will have had madams she knows who have connections with the Pleasure Dome, and Rovan probably knows some decadent noblemen. Lola and Rovan are pariahs in their former communities, so such an encounter will be tense and interesting to play out.
I'm all for brainstorming and creating a contact with the group. I think that finding more about Erin's life, Lola taking the party to see one of her madam friends, or Rovan meeting an decadent noble he knows all have fun possibilities, but I am open to suggestions.
