Thank you! Sorry for not responding immediately, I agreed with G.G.Grimalkin's response!
I just wanted to pop by to say that I'm actually also currently working on an expanded bestiary for FORGE, one that will hopefully again include plenty of art by Chaoclypse.
There was some discussion around the bestiary on our discord, and I hope to provide more updates as I make progress soon.
My plan is to also include many nested encounter tables for creature types and terrains/biomes, which should make it easier to use and also ensure random encounters feel coherent.
