Na dude Jigglypuff had it right, he was talking about the protag of PQ2 being the child of the current Protag (just with a delayed birth of 300 years), living with the descendants of his siblings... aka grand/great nephews/nieces.Minor nitpick...
Nieces and nephews refers to the children of siblings.
Since they're all his kids, they'd be his great, great, etc, grandchildren.
I'm kinda curious how incest rules would play out for this senario
