Love the illustration of the Childen of Oltinxol—and the name is a fun easter egg :)
I also really like the addition of rival delver Quiver Nightingale as something of a faildaughter steered by her competent retainers. Great touch.
Parts of the dungeon ecology confused me a bit, though. Nele Methoataskemik
is a pretty wild creature to just be hanging out in the corner of a dining room: What's it up to? How does it along with neighbouring alchemist Eben? Those sorts of questions.
Fun loot table and lots of intriguing material, though. Nice one, Teresa!
