28- Captain’s Wench
This is an upscale dockside working girl (oxymoron?). She will only "be with" a Captain or Officer. She is prettier, cleaner, and more refined than what one would expect. She is more of an escort, making the captain buy her drinks and food (as well as others). She actually works for the house to promote people to spend.
The local band of 'nasties' (goblins / orcs / whatever) lives in relative peace with the local population.
Along come the PCs and go through their usual heroic monster bashing routine, wiping out the nasties and pinching all their stuff, then continue on their way.
Problem is, they don't kill ALL he nasties. The survivors want revenge and, after spending a few months recovering, start to take it in their own inimitable style (which is not unlike that of the PCs come to think of it).
Next time the PCs are in the area they find themselves VERY unpopular with the townsfolk.
