Here's a cutaway of the deck of the caravel for reference. 1 square equals 5 feet or roughly 1.5 meters.<br/><br/>(https://i.imgur.com/jskWREX.png)<br/><br/>You stand at area 2, which is the same in both the top down and cutaway view. The stairs go down into the ship's hold. Rehner is asking you to accompany her into area 5, which is tucked beneath the forecastle along with crew cabins.<br/><br/>The<em>Mercy </em>is much smaller than the<em>Charlotte, </em>and a no frills experience. I didn't get a sense of what your characters' expectations of comfort were from the saloon, but for the NPCs at least, it will be a shock.
