It’s common knowledge that Absalom is a large, sprawling city, full of districts and neighborhoods with distinct cultures and residents. Even the savviest of citizens, however, rarely realizes just how much real estate lies beneath the city. With its near 5000-year history, including Aroden’s ascension, natural disasters, and sieges, Absalom has been built, destroyed, and rebuilt on top of itself too many times to count. This has resulted in an unfathomable network of tunnels, chambers, and caverns beneath most of the city, with regions as distinct as the locales that bustle above.

It’s no surprise that Absalom has a wide network of sewers, but in 4712 ar the Grand Council authorized the building of a second set of sewers to account for a population boom in Westgate. This sewer system runs below the original sewers and connects to just about anywhere in the city. While undeniably unpleasant to visit, both sewer systems are used regularly by those who would prefer not to travel above ground.

There is no known complete map of the undercity.
