Mainland contains multiple NPCs with the Caravaner, Gondolier, or Shipmaster class who do not offer travel services. This means generic greetings and voice lines will not match reality. Some could perhaps be switched over to the Sailor class, others should receive entirely different classes with potentially some unique background/my trade entries to make them appear to be what they shouldn't actually be.
