Here are the drawings for the next map. I wanted to design the sewers in a fairly realistic way, so I did some research. It turns out that, for most people, your toilet does not lead to a place that would make a good fantasy map.
There are some exceptions, though. Are you in London? Your waste actually does goes to fantasy map sewers. Vienna, too. And in Cologne, Germany, there are two chandeliers in the sewers. I mean, you expect a place to be classy when it’s literally called Cologne, but that is really above and beyond.
