Yup, two locations in Saltmarsh - the priest of Obad Hai and the owner of the Winston Store. But, again, you're making my point for me. There's EIGHT CHAPTERS in this book. ONE chapter has a grand total of 2 halfling NPC's, and that's MORE than what you find in many other modules. There are a number of other towns and whatnot detailed in the module. Guess what, no halfling NPC's.
Oh, wait, I tell a lie. In single mention of the council in Tammarault's Fate of a cheese shop owner that there's pretty much no reason to interact with.
So, in a 250(ish) page module, halflings appear in a single section, and even then, it's mostly just throwaway elements. It's entirely left to the DM to actually detail any of these "halfling villages" which make no appearance anywhere in the module. They aren't even marked on a map. No locations, no NPC's. Nothing.
Which is still MORE than you see in many other modules.
So, if halflings are supposed to be "common in town", then, again, WHERE ARE THEY? What do they do? What role do they play? What do they add to the adventure or the setting?
I keep asking for examples of how halflings are being utilized in the adventures, and you guys just keep making my points for me.
