Hi, sciencephile
Thanks for considering my feedback! I agree that it is subjective, and had the same thought about the skulks and their potential hiding places. The reason I put them against the walls in the end, though, is that their chameleon skin would be more effective against a wall.
I do think the hidden beast wouldn't be on the throne, but can see that it makes sense to place the token there if you're using your method for handling illusory creatures. The drawback with this is that the token image and size don't match the illusion. (And in the case of the Pea**** Shrine, there is no other creature there to stand in for the pea****.)
I do use the "skip hidden actors" setting, which I think is very useful overall, but I must admit that I have had to drag the current actor flag back once or twice when I haven't revealed the NPC in time!
