I'm currently fighting to try to subjugate Ostlandet, and my son/heir prompted this message:
My current king (Jarl Tolir) is 56 years old, and I expect him to die at any moment. I just had a successful revolt for independence against the Queen of Sweeden, so I had to push his Ambition to become the King of Norway as soon as possible. I have another son, but he's a chaste-craven-homosexual (which is not heir material). If Hrane goes off to join the Varangian Guard will I lose him forever, or will he return when my current king dies?
Should I allow my only good heir to join the Varangian Guard?
