O.o why would someone attack a plague ridden nation. Also eternal, can you put your entire nation on lock down? Close all movement in and out of Torfas and quarantine the immune, non infected, and infected separately. They didn't have good medicine back then so they would just wait for a plague to die out. I mean you already got most of it quarantined but you can't risk one person getting out and infecting the entire sum of surrounding nations.

Edit: I won't be on later today
