My story is fantasy based in medieval/renaissance Europe. A group of three scriveners (a family) are invited to have an audience with the king to discuss a project he wants to commission them for. I'm looking for etiquette that middle-class merchants would go through when visiting the king. They are not members of the royal court either. I am guessing there is a lot of "don't speak unless spoken to," including a lot of bowing, and I'm trying to figure out where they might be received (throne room? private office?), as well as other important details.
