The Underground refers to the complex underground plumbing system in the city of Ithcona. The pipes contain three layers: Level A, Level B, Level C, and Level D and Long Rats. [[File:Underground City II.png|thumb|365x365px| Image: "Underground City II" (Cropped) by fmacmanus

These pipes usually tend to be more narrow, and most adults have to hunch down to crawl in and out of them. When it rains, the openings to the pipes below Level A seal. At least 1-2% of the homeless living in the pipes die annually on this level from heavy rain draining from the city into the pipes. This section has clean water.

Level B refers to the freshwater pipes where most of the homeless live. These large pipes reach a diameter of 500 feet. These pipes usually have clean water constantly flowing into the apartment complexes overhead. Underneath, the thermal pipes below provide warm concrete for residents to rest on. The residents of Level B commit mild to moderate crimes. The authorities suspect approximately 800 people live in the pipes. To preserve the integrity of Ithcona's fresh water, police officers try to forcibly displace the homeless communities in Level B. As a result, riots frequently break out in this section.

Level C describes an uninhabitable network of thermal pipes ranging from 140 to 160 degrees Fahrenheit. Many people need to enter Level D or Level B before they suffer from heat stroke. Some parts of the pipes reach 180 to 212 degrees Fahrenheit. Frequent travelers usually suffer first degree burns. This section has clean water.

Level D describes the underground layer of sewers furthest from the surface. The sewers reach from Ithcona to New York City. The communities in Level B banish and band together to protect themselves from the people who reside in Level D. The residents of Level D commit the worst crimes and prefer solitary over a community. This section has contaminated water.
