Fantasy Sewers Encounters

Sewers in fantasy are a combination of city environment and dungeon. They are places where oozes lurk, shady deals are done, and cultists perform nefarious deeds.

It's also a place of muck, waste, stenches, city workers, blockages, fouled waterways and forgotten ruins.

There is a fantasy encounter generator at ChaosGen. There is also a pdf of these and more tables at the DriveThruRPG as Sewer Encounters.
