Its the ongoing evolution of Paizo's take on the Aboleth and related creatures.

Alghollthu, if paizo used them more, rather than leaving them as background elements I think could reach that type of status.

Goblins, kobolds, and leshies all have some aspects of iconic/mascot

Pre-remaster I felt golems were overused a lot in APs and are linked to the paizo logo, but still not as defining as beholders or mind flayers are for D&D

Packing issues, and forgetting a couple of pieces, meant the map was slightly smaller than intended, and that had some negative IMO interactions with the adventure, but I still got useful feedback. Still need to see if I can adjust 1-2 items for better flow and more interesting interactions!

My non-PF2 books tend to stay on their shelves, unless I'm remembering something from years ago that I want to double check. And then about once a quarter I go around the house and find all the books on the desk, or sofa, or counters and put them all back. PF2 are always where I last used them
