The Rot

The Rot is a region exclusive to the Downpour DLC, with being the only Slugcat that can access it.

Overview
The Rot is the deteriorating Five Pebbles region during the peak of its rot infestation. Much like Unfortunate Development, the region features fluctuating gravity as well as an abundance of, , and. Due to the superstructure's increased intake of water and mechanical failure, some sections of the region are completely flooded. The region offers complete protection from the Rain, making hibernating optional for survival.

Primary Cortex
As the General Systems Bus has been rendered inaccessible by the Rot, this subregion is the main path to reach Five Pebbles' chamber. Adding to the region's dangers is a set of arrays that emit deadly green electrical discharges.

Recursive Transform Array
The only area of Five Pebbles that remains mostly untouched by the Rot. Mostly the same as the original, except for a few altered rooms and the fact that the flux condensers can temporarily shut down along with the low gravity, making them safe to the touch.

Linear Systems Rail
This place houses Five Pebbles' Mass.

Depths
The combined remnants of Unfortunate Development and Memory Conflux, twisted and mutated so badly by the Rot that they're nearly unrecognizable. They're filled to the brim with Rot hazards, including at least two.

Cystic Conduit
The Cystic Conduit is Five Pebbles' lymphatic drainage systems, which pump water throughout his superstructure and eject the debris to the outside world. These effectively serve as replacement connections to Five Pebbles rooms that would be otherwise inaccessible due to the Rot.
