The Ancient Sewers is a third level biome.
One could believe that the sewers could not get worse than green. However, this deeper part of them is proof that it does get worse. Much, much, worse. An unusual filth gathers on the floor, the walls, the pipes, and the ceilings, hardening. The air is horrid, and would easily be a hazard for the lungs of many. Spiders have made their home among the crannies and cracks, and so has the slime mold. As well, all those undead bodies... All those rotting bones... They look appetizing for the hungry scavenging worms. And even the fungi has started to search for prey.

Secret areas[edit | edit source]
The blueprints for many upgrades can be found in secret areas of this biome. The Alchemic Carbine and Front Line Shield can both be found in areas with poisonous water.

Enemies[edit | edit source]
Many enemies are common between the Toxic and Ancient Sewers, including Disgusting Worms, Kamikazes, Scorpions and Zombies. A unique feature of the Ancient Sewers is the presence of the mushroom enemy Impalers, which can sprout highly damaging spikes from the floor, remotely aiming for the player in a wide range. Apart from Zombies, which are replaced by Failed Experiments on 4+ BSC, all other enemies are present at all difficulty levels.

Lore[edit | edit source]
Conjonctivius lore[edit | edit source]
Main Article: Conjonctivius
It begins with a nameless, faceless corpse in the Sewers, likely infected by the Malaise. The body is bloated and one of its arms has mutated into a tentacle. Green goo trails from the body towards a small hole in the wall. After this encounter, the Beheaded finds that same trail of green goo and an empty cocoon next to a bigger hole in the wall, which was made by an adolescent Conjonctivius. Later, the player stumbles upon the trail of green goo close to a corpse. The trail leads to the remains of a huge cocoon and a gigantic hole, which was carved by the adult Conjonctivius as she escaped. Finally, a message left by soldiers tells how difficult it was to chain Conjonctivius, likely an order of the King. This explains why Conjonctivius is imprisoned in the Insufferable Crypt when the Beheaded arrives.
Malaise lore[edit | edit source]
Main article: Malaise
The Sewers seem to have been central to the spread of the malaise, through the water supply system. For example, piles of contaminated bodies are found rotting in the sewer water. Upon finding them, the Beheaded wonders if those bodies are responsible for the initial infection of the citizens, or if those bodies only helped spread the Malaise by contaminating the whole water network. In a Grimoire found in the Sanctuary, the Alchemist writes that people believe the sap flowing through the walls of the Sanctuary is responsible for the Malaise, by contaminating the sewer network. He also suggests that this same substance could be the solution to the epidemic. it is unclear if the substance is in fact the source of the Malaise or if it's only a rumor. What is sure is that the Alchemist harvested and used this substance as part of a treatment for the infection, as indicated by the Grimoires of the Ossuary and the Clock Tower.
A giant broken door is found next to a soldier message warning not to open this door, lest the rats would get out and spread the Malaise. The Beheaded remarks that it is unlikely rats made such a big hole, which implies something else was kept behind the door. It is unclear who or what was behind the giant door. The lack of green goo trail, the fact that Conjonctivius is still in chains when the player reaches the Insufferable Crypt and this lore room being part of the "Infection" room series and not the "Beholder" (Conjonctivius's old name) series suggest that the creature which escaped was not Conjonctivius. The corpse of Prisoner 236 is found close by: he presumably died while trying to escape.
Alchemist Grimoires[edit | edit source]

It is becoming increasingly difficult to collect mold samples in these sewers. There are too many revenants.
