No, the custom NPCs aren't in yet. This is a workaround that lets you mess with existing NPCs by including them in your character description. I just enter in something like, "Rosalyn likes to bully him." in the character description and BAM, Rosalyn is a bully and likes to push your buttons. I tried making it so no characters could speak and got some interesting stuff. Just a fun way to mess around with what we have.
