I have an half decent heir coming up, but his little brother would be so much better (genius with 27 diplomacy and 18 stewardship!!). Is there a way to get rid of my primary heir? Right now my second son (the genius) has left my court to go to the court of my vassal who hate me the most (my son also has like -60 opinion of me). If i let a faction put him in control of my kingdoms, would I control him when i die? How can i have him as a successor?
