Just a pointer on that boat. In Talad's own words, he said there is little to no wind on the first level, and no wind at all on lower levels. All boats would be muscle powered.
One other thing that has been bothering the back of my mind. This city is meant to be on the large lake, right? The lake that rises and falls several Levels daily? Just wondering if that has been taken into consideration.
Nice work all.
