The Uttershroom
From The Fifth City Wiki
A giant mushroom in the unterzee. There is little here. What few people live here are addicted to prisoner's honey and are too scared of zee monsters to leave. These people are related to the people on the Chelonate, who are famed monster hunters. Those that did not want to hunt, came here.
This may be the original home of the Blemmingans. They live here, at any rate.
