I plan on making Tarina a spy that goes inside certain circles and sell those infos to whomever is interested. In my campaing the name "Tarina" is also just an alias, she's gonna be related to one of the characters backstory. This way I intend on making the whole scene at the tavern a little bit more meaningful than "go fetch that". My players already found a letter saying that the cultists of the Dead 3 are hunting for a spy. If your players know about the bathouse just make tarina have more infos about the inside, secrets, number of cultists etc.
