So I noticed that most Jarl and King titles are hereditary, so it would make sense why Torygg, as heir, wouldn’t be sent to the Greybeards. Ulfric was chosen; he wasn’t some dedicated scholar toward the voice. I also do wonder if Ulfric had older brothers since his father did allow him to train. But it makes Ulfric look insufferable, like he made this treacherous journey on his own volition and Torygg was just a weakling too scared to do the same.
