Wait! What decision?Various jewish cultures often become landless except separdhi because they are covered by Iberia events.
Picts go extinct pretty fast but will linger for a while as landless characters before dying out. Whats cool about picts is that not only they and other cultures of their group have a unique decision that helps you to convert and reestablish your culture but they also get unique names for various titles in the region. Like Sctotland becoming Pictland and Brittania becoming Pictavia.
