The text is already written, yes. The map is intended as a part of a game package and is just a normal paper map, not interactive in itself.

The map has been "sliced up" already in the PDF version but I've sort of "unsliced" a a couple of the submaps, mainly that of the town and the sewers, so I've sort of shot myself in the foot deliberately. Merging the two makes more sense and the main difficulty is where the two join, not particularly where they go in between. In the sketchier image above the steps down to the bridge are supposed to lead under the arch of the bridge where there is a door leading to the sewers via a vertical shaft. In order to accomplish this I've decided to resort to a cutaway in the bridge. Cutaways appear frequently but I don't want to overwork that practice!

Another interesting aspect to designing the map is "unboxing" the locations. "Sewer Tunnel" leaves you a lot of latitude as to the dimensions of the location. So it's not all bad!
