OOC: The challenge has just begun, so there is plenty of opportunity to participate. They are just stating their respective cases at the moment. Also, diplomacy and talking is not the only things you can do to help resolve it; other actions can make the stubborn arguers more receptive to the talking.
Adolfo and Nathaniel start to set up camp and tend to the horses while the party deals with the argument, ready to help if either side asks for it, but staying out of the way until such time.
The noble remains stiff, though his workers seem to eye the campsite as they start to show small signs of impatience with their lord that they try to hide. "I am Lord Marvox, and I understand that an inn by itself does little, but I have no time at the moment to discuss the greater issues and my plans to help resolve them."
The druid meanwhile, ponders her response as she takes a measure of the party's intents. She finally replies cautiously, still very tense and watchful. "One must always look beyond what is immediately in front of them. This fool moves forward oblivious to the challenges presented by those in the Feywood and the other creatures in this supposed "empty" land, letting greed and money cloud his decision making. The last time the road was active, there was much abuse by those who used it, and it was by the mercy of the heavens that traffic stopped before it reached crisis. Now the fool wants to reopen the old wounds."
