The Last Living Member of the Royal Line

The last living member of the royal line. What? I think there are some royal line and they were escaping prosecution. See I read this story in San Belt surviving the wilderness where it was like these deeply orthodox Christian Jewish kind of hybrid things. Instead of giving up the religion they just like fled their little village into the wilderness of Siberia and lived there forever. They shared this insane story about how one year there was like a late frost and it like killed a lot of the like plants they naturally grew around.
