Also, I’m not really sure why all the nations were fighting the Triglav. It appears to just basically be a period of rapid and violent expansion, which all the other empires also have done. And as to infighting, that happens a lot in the empires too! My personal viewpoint is that the empires don’t want another nation muscling in on their patch.
Why aren’t the Triglavian Collective allied with, or formally recognised by, the other nations? Sorry for the long title.
