Sewer Complex
Sewer Complex (1200 dpi)

Welcome to the sewers… This complex of passages, sewers, collection pools, and drainage outlets is designed to be a central feature in a fantasy sewercrawl environment. You can link it up to the two sewer maps from Waterdeep Dragon Heist, add a bunch of the sewer elements that I have posted to the blog over the years, and it also has four connectors designed to be linked to the six sewermorphs posted last month and the 12 more that are coming this month.

In fact, there’s enough sewer action going on that tomorrow I’ll go through the blog and collect all the sewer maps and make a new sub-page to make it easier to find sewer sections for use in your games.

The 1200 dpi versions of the map were drawn at a scale of 300 pixels per square and are 12,000 pixels (40 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 2,800 pixels wide or 5,600 pixels wide, respectively.


This map is made available to you under a free license for personal or commercial use thanks to the awesome supporters of my Patreon Campaign. Over 500 amazingly generous people have come together to fund the site and these maps, making them free for your use.

Because of the incredible generosity of my patrons, I’m able to make these maps free for commercial use also. Each month while funding is over the $300 mark, each map that achieves the $300+ funding level will be released under this free commercial license. You can use, reuse, remix and/or modify the maps that are being published under this commercial license on a royalty-free basis as long as they include attribution (“Cartography by Dyson Logos” or “Maps by Dyson Logos”).
