Atlantis is one of the 2 largest cities in the Lower Elements, the other being Haven City. It is never actually described or visited by the characters in the book series, but is mentioned frequently. Especially its prison complex, Deeps Maximum Security Prison, where dangerous criminals such as Mulch Diggums and Opal Koboi are detained.

It is underwater and protected by a giant air bubble, and many, if not all, of the civilians use gills to breathe. More about the city is revealed in The Atlantis Complex. There is a lobby to demolish the city due to the high long-term maintenance costs. However, the Lower Elements Police Council has refused to take action due to the short-term financial cost.
