Just know that each country has a different style and culture where their military is involved.
Connlaoth is a union of duchies that are united under a grand duke but have their own individual priorities and goals. They are more similar in government to feudal japan, though their aesthetic design is very Germanic. They also hate magic and magic users unless the magic in question is divine in which case it's deemed "miracles" by the church. They have the highest tech level of any country as a result.
Serendipity is a true kingdom with a monarchy but each province is very much like a state. They have their own local military that is at the call of the high lord or lady who is sworn to the crown. In most cases the ruler is of noble blood and has some blood connection to the crown, which in turn has them all scheming to get that thrown, so who knows who might withhold troops or delay in sending them, in the hopes to gain strength over a rival. At the same time, those that are quick to the Queens call might find themselves in her debt or gain her favor. The government is most like feudal Europe but it's not an exact copy by any means. Serendipity is very magical and they are proud of their fae heritage.
Adela is indeed a warlike country, but that's mostly internal at this stage in their existence. They are a fiercely tribal country that was conquered and massively influenced by Serenian rule. The country is undergoing a major rewrite at the moment, so it's not been completely revealed what the state of things are now. What I can reveal is that the tribes are competitive and continue to fight amongst themselves in border skirmishes that allow for the constant flux of those borders. Rather than states or provinces, the country is split into territories. There are over arcing Adelan themes, but from tribe to tribe, things are a bit varied. The Country is held together by the might of the Dragon tribe, and their dragon riders.
Hop ethat helps. Have fun!
