Anyone test if adding a blanket quality to the town in your player description for custom NPCs works? For example, if you add "everyone in Silverpine is a secret shapeshifter." Would that apply since the game checks your character description for dialog with each NPC and make them all shapeshifters?
Edit: This has some interesting effects. I was able to have Rosalyn be a feral fox (which surprised me, since she was described as using her mouth and nose to manipulate things, it seems to have gone the whole nine yards with this one). Turned everyone into women. Made everyone walk on their hands. All by adding that detail to my own character description. I just wish I had more than 400 characters so I can go wild with it.
