Which nations represent order and good?

[Agema]

I find it extremely hard to characterise many of the nations as "Good". What you call "good" - using a Westernised RL definition - is a nation that you perceive that looks after it's population reasonably fairly, and potentially treats other nations humanely.

You could draw from Pythium and Marignon's description, for instance, they are trying to save itself from the corruption of Ermor, the former probably much more benevolently than the religious zeal of the latter. MA Ermor might have been corrupted by death magic from EA, but they're trying to fend it off (and we can gather they fail from LA).
