Hello. Glad you're enjoying Lineage. Not a dumb question at all. The "Princely lines" table is intended to refer to the parent of the new heir - the prince/princess who was the brother/ sister of a monarch, and then uncle/aunt of a monarch, who never got to rule themselves, and who probably spent a life in the shadow of their elder sibling. What influence or expectations were put on the new monarch, being raised by such a person?
