For Reference, the sides in the war are Kindara/Zonasa vs. Cathay/Arcaea/Sorraine/Ohnar West . . . the geography involved means that Kindara, Zonasa, and Cathay do most of the fighting, though Arcaea and Sorraine get to do a fair bit as well. Ohnar West has a really long way to travel to get to the fight. Arcaea I think is doing other things than just fighting, I believe they are also colonizing rogue regions that they plan to make into its own realm at some point. I don't know how much of their army is devoted to which thing, but they certainly weren't bringing their full army south.
I'm one of the colonizers...I certainly felt like everyone else was in the south, while the army was away at war. I think at least 75% of our nobles were gone, possibly more, although I wasn't paying that much attention.
