[Libertas Omnium Maximus]

Libertas Omnium Maximus would side with those who opposed the Darya faction, though I suspect they would avoid open affiliation with the communists. In reality, they would probably be fighting more with the North Hespian nations. I simply can't see a nation of 20 million committing their troops to fight in a war that far from home. 

I might suggest that the North Hespian nation nearest to Shuell be Germanic in culture, reflecting the surrounding states. With that said, I'd like to avoid making them 3rd Reich 2.0, perhaps this means giving them motives outside of the standard "ethnic cleansing and spreading the superior race" reasoning.
