Sewers and Cesspits 2

So this is second post on this and i thought id go into bit more detail. This is intended to be underneath my campaign city Shadelport. It is a pirate city today but is also built of the ruins of the pre human monster empire's maritime capitol. it was where the great revolt broke out and a succession of human barbarians ruled then a dynasty of necromancer kings then the world was flooded separating the main continents. So Shadelport still has large sections of ruins and structures built by pre humans and necromancers. The upper levels of the sewer systems are the most modern built from red brick mostly in circular tube tunnels with liquid waste flowing through the middle. many are a trickle in dry season, others are larger with canals used for waste and goods transport. The older and deeper areas  tend to be trapezoidal or hexagonal with lower halves filled with waste or muck or water with walk ways on the sides. There are many deep levels unexplored by humans. The bridges also have many hidden internal spaces and levels going under the harbour and river. Some of these areas have higher air pressure, especially areas accessible through water locks.

This post includes a table for strange things to find especially on the deeper levels. Also a table of hazards including architectural and environmental risks. I might try and make some sewer geomorphs to print and rearrange. A later post will be for the sewers of hell which might connect Shadel Port to the drains between the layers of hell. Sewer rangers and druids might see warning signs of some hazards by observing roaches and rats.

Part 3+ will be sewer physical features and a tables for sewers in hell
