Back to the sewers. Fantasy sewers look like… well… like no actual sewers in the world. They are a strange mix of catacombs and wide-open waterways with raised walkways that might be slightly related to modern storm sewers but are definitely not related to any real-world waste transportation system.

So many sewers have shown up on the blog over the years, plus the ones I drew for Dragonheist (which I’ll post as portfolio pieces in a few months). During one of my first drawing streams of the new year, I got a request for more “connectors” that will link the various sewer geomorphs and points of interest, but focusing on more twisting and turning structures than the nearly straight connections I’ve posted in the past.

The main thing about these connector sets is they don’t have a primary “point of interest” like a lair, thieve’s guild, secret temple, cult shrine, etc. They exist purely to link one set of sewers that do have a point of interest to another. In this case we have a confluence of multiple sewer lines from the north, east, and west that meet in or around a large circular pool before flowing further south. There are two access points to the surface, one a small basement in the southwest corner that also has a secret passage leading further under the city; and the other at the north end of the map with a narrow set of stairs leading down from above that is used by workers (and likely adventurers) accessing the sewers in order to fix problems down here.

The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 7,200 x 19,200 pixels (24 x 64 squares) wide. To use this with a VTT you would need to resize the squares to either 70 pixels (for 5′ squares) or 140 pixels (for 10′ squares) – so resizing it to either 1,680 x 4,480 or 3,360 x 8,960, respectively.
