The chase doesn’t end in the cellar.
Beyond the hidden passage, the tunnel opens into the sewers, marked by signs of a recent passage.
The party is still on the trail.

MAP DESCRIPTION
Passing through a long, slime-covered tunnel, you emerge from a large pipe and step into the Sewer Chamber, a wide stone room carved beneath the city streets.
Torchlight clings to the wet walls, reflecting off the stone and the foul, greenish water of the channel that cuts through the room, slow and thick.
The original structure of the chamber has been roughly altered. A small wooden bridge and a raised platform have been added, creating a useful, though not particularly safe, path toward the exit.
Where do these sewers lead, and more importantly, what disgusting enemies might crawl out of that sludge?
NOTES
Map Style & Tactics: Sewer Chamber is designed for tense, close-quarters encounters with strong terrain control. Small bridges, narrow passages, and open lines of sight over the channel make positioning essential.
The Channel: The slimy flow may conceal creatures of many kinds beneath its dense waters.
The Conduits: Particularly small or fluid creatures could slip out of the sewers by squeezing through the bars.
Sewage Water: Falling into the water could cause poisoning, slow movement, or force characters to risk slipping and ending up prone due to the slick surface.
The Crates: They may hide clues, documents, or interesting objects needed to continue the adventure.
The Key: To open the door, the key might be carried by an enemy, handed over by an ally, or hidden inside a barrel filled with sludge.
Secret Passage: The large pipe set into the grate at the center of the room is intended as the map’s entrance, but it can just as easily be used as a secret exit.

Welcome Back, Fellow Darkish!
Sewer Chamber is the natural continuation of the secret barrel passage from the Tavern Cellar map, and an excellent way to draw the party quickly into an interesting situation.
We will certainly continue exploring sewers, a theme that has always fascinated us and that we have long wanted to develop in greater detail.
We hope you could almost smell this place just by looking at the map, and that your players will soon smell it as well.
Let us know what you think by leaving a comment or a like.
For this map, that’s all.
We wish you great adventures and NAT20s!
