Modular Sewers is a Modular Map that you can use to build your own underground Sewer System in a matter of minutes, or improvise it as the players explore. Using the variations, you can also create a lava dungeon or toxic waste canals.
It can also be combined with many districts to create an underground city:
Modular Sewers 1: 24 tiles.
Modular Sewers 2: 18 tiles.
Sewers City Center: the city center of Nightwater. With a market plaza underground.
Sewer Water Houses: a small neighborhood with houses built over the water.
Sewer Outfall: the end of the pipes and where all waste toxic waters go. The perfect place to sneak into the city.
Sewer Thieves Guild: Base of operations for thieves, smugglers, criminals, assassins or any other crime organization in the sewers underground.
You can also use the Free Procedural Generator in Foundry to automatically generate random sewer systems.
This pack contains 24 tiles with a big Boss Room, all of them are fully modular and 100% seamlessly tileable. There are 6 variations, for a total of 144 total tiles.
