I'm playing an old version of Crusader Kings 2 (2.1, I think). At one point, Paradox updated the game to include more mercenaries and holy orders. As I was the Irish King at the time, I had the option to create the Irish Band. However, I didn't realize its potential, and as it used up one of my duchy slots, I somehow got rid of it.
At present time, the Irish Band, as with a few others, exists, but has no leader. This means I can not vassalize it.
Is there an in-game method to add a leader to the band?
Alternatively, I assume I can use the console command
give_title to hand it to a random character (and then vassalize him), but I'm currently looking for a non-console solution.
