This location was accidently discovered by Daxter when he fell into a hole in the streets of Aeropa, upon returning from the Danger Course with Jak. Shortly after taking in the scenery, he was contaminated in a deluge of Dark Eco, transforming him into Dark Daxter. In order to find his way out of the Sewers and return to Jak, Dark Daxter had to contend with eels and spiders, as well as malfunctioning electrical systems.
The Aeropa Sewers contain a long series of earth and metal tunnels, separated by metal doors and in poor repair. They are accessed through a sewer grate or pipe and exited through a lift. There are also some Dark Eco Crystals in the area which allow Daxter to recharge his dark power. Throughout the area there are some mechanical devices like crush pistons and auto turrets.
