I've never played Cloud Empress and only started to read the rulebook after getting this module. I like mycology and love the concept of geothermal settlement to the extent I'm building a geothermal greenhouse IRL. It's a compelling story on its own with likeable characters and plenty of conflicting interests. Not just between characters but between their own needs and motivations. The reason the world works is also why it's mysterious and threatening. I admit I haven't read too far into the timeline and possible solutions pages to not spoil them in the future.
Some of the tables do require the core rulebook to know their values, which I will post here under Fair Use. This expansion references them as being on "page 34" but I found it on page 40 (in the Table of Contents either way). The rulebook is now free but if anyone happens to only be playing Slipping Through the Cracks like me, this could be helpful:
