Thank you! I think what I'll end up doing is making a character that is very old and generally less able than younger players, but who can give some direction and context while my players and I all figure out the system.
It also might be interesting if this character is taken away from the party temporarily for any number of reasons related to their age or health. Or if they just sit in the bar like your companion in Witcher 3's first chapter, HEH.
I appreciate the clarification. Thank you for posting this errata. I'm sorry if the question is asked a lot. XD
