There are some really strong social dynamics for PCs to play off of here. I could see this going lots of different directions depending on how PCs approach, what they're hoping to get out of the situation, and how things go sideways. The detail of what happens to Qexill if he tries to hop into the titan is grody in just the right way. I also really like little details like the fake Boetzu worship and the "Lizard Coast." Very evocative and very Appendix N.
