Yeah, let's get our stuff back (partly to save Lehe the trouble of editing the inventory list) and then speak with the Sand Mother. We can probably get some info on where this floor's exit(s) are, and get some info about the bug caves to the south and a bit more info on the mountains to the west.
The curse being contagious is interesting. It prevents the Naga and Lamia from breeding with each other, but it makes others they fuck get an addiction to snake cock? That makes me think this was, in part, one of those problems set up to interfere with the Chosen's journey. Now that, at a minimum, Yulia and Cherchiel have been infected, we need to deal with this sooner rather than later. While the Naga and Lamia here are well-intentioned, if a bit out of control, I'm sure there are other enemies on this floor that can and will take advantage of this situation.
