Sewer Connectors (2026 A) (Patreon)

Many, 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.

This is the result.

We have two different stretches of sewers here that you could link together by stacking the left one above the right one, or turned 90 degrees counterclockwise and connected to the top left of the second one instead.

The left one contains two access points to the surface. The first is at the top and is a traditional “fantasy sewer entrance” as you would find in a number of CRPGs when you open an anachronistic demihumanhole. The second, at the lower right end, is the basement of a butcher’s or some other business that has a channel for disposing of unwanted liquids into the sewers below. A ladder leads up to the business proper, and the trap door is locked and covered because one time a ghoul managed to crawl into the basement through the channel.

The right hand set of sewers is a lot more direct – with only one chamber off of the sewers, probably used to be someone’s basement but is sealed off and used for maintenance and storage by sewer workers now.

The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 7,200 x 9,600 pixels (24 x 32 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 the recommended 10′ squares) – so resizing it to either 1,680 x 2,240 or 3,360 x 4,480, respectively.
