@forsaken, can you give me some ideas on exactly what nights are like in this world? How many monsters will appear, how do they react to other monsters, etc.

I see two lines of action. One is to turtle down somewhere, for example using spiderform to weave a web high up in some trees and wait for dawn there, but uf there are lots if flying monsters who can somehow tell the precense of humanoids that might not work.

The other approach is Eria using her superior stealth to scout a path for the both of us, but depending on monster density that might not work.
