Flavor text can be used to enhance the players experience when he or she enters certain areas. The text may convey information that otherwise would be lost to the player such as smells or sounds that would be hard to indicate in other ways. The following tutorial gives one way to add flavor text to a module. The tutorial explains a method for creating an invisible NPC, a dialog for that NPC, and a quest file to initiate the dialog when a player enters a specific trigger zone. Since this uses a specialized NPC to do the trick, reading and understanding Talking NPC: How To would be beneficial.
