My son and original heir at the start of the game had a terrible time though. He contracted cancer around age 26, I went experimental bc he was my heir but that resulted in him losing his dick so he lost his claim to the kingdom anyway. He lives 5 or so more years like that before I tried another treatment that resulted in him losing an eye and then he died a few months later just a few months before I crowned myself king of Ireland. Poor kid, at least he had a son first bc I can only have daughters apparently
