I've been trying to figure out how this title works for grandchildren of the ruler of the Iron Throne--it seems automatic because I've never had to grant it to a male-line grandchild, so I was thinking of trying to tweak it a little so that the grandchildren of the Lords Paramounts are "princed" too (or rather, given Lord/Lady titles) but I can't figure out where to even find the "princed" title. Help?
