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.
If you want to add a "supernatural" touch to your campaign, define the rules of magic and the universe. Make your players comfortable with those rules. Then your new supernatural creatures must then break those rules.
