I can't see a reason why wouldn't Fronen want Jidington, Thromegor, Bym, Eylmon and everything south from that line. Rich, perfectly defensible...
Nobody likes watching the realm they've played in for so long go the way of the dinosaurs. Further, I believe both countries suffer from the general lethargy that makes this whole scenario that much more difficult. If they are having fun doing what they are doing, then good for them.
All I'm saying is that they
might just have
more fun down south!
