I think you're missing something. You can pass on knowledge to new characters (especially children) but you can change their personalities, life goals, wishes, weaknesses, virtues. There is nothing wrong with a Perth coming to Atamara, and having had his personality warped perhaps due to his family having been "disgraced" or something on AT. Could be a character seeking redemption. Or perhaps a character who feels dejected and worthless.
You're right.
I think I'm just going to wait until the current conflict is concluded though and come back hoping for some fresh ideas and happenings. This war has worn me out.
