something like a scorpion/spider is squished in ch2 - In the last quarter of the book there is a place full of thousands of spiders. They are magical and don’t attack, but one is part of an awful ritual.
Walls and buildings crumble and people are trapped (it is unclear if anyone was killed, but probably). There is a mention of a sleeping immortal buried underground.
A character is super nervous about something (positive) so she makes a joke about throwing herself off a high place to avoid it as a self-defensive habit
