That's not a bad idea. In the old days The Hanged Mans purpose was to act as neutral ground for anyone to 'hang' out but with all the changes over time, that has become something else. Also one of the problems of starting any new area or settlement is that people tend to not like run down taverns or crummy outposts so over time they become more and more grand.I think what could help too is if there is a middle ground board somewhere too. Maybe New Emberlight could be a place where Mistral citizens on a market board can request a builder's help. I think enough people go there that word could be spread to builders in Shadgard?
To solve this, I believe a very simple delivery waystation, like a pony express rest point, could be built half way between Mistral and Shadgard. It could hold a post board and even offer some minor services. It could even become an event where builders are called to help, build, the place. However, I think it important to state that this should always remain a small, run down waystation and not let it escalate to anything more than that.
