Also, to be fair, if that's true, it just shows the extent that the CE was involved in international politics. Making demands for another realm, which that other realm didn't even know about!
As a character, Saeculo likes the CE, and is actually quite supportive, he was born there and has his family estate is in Etoge. He's a first generation colonist and so his loyalty is always going to be split somewhat. (As time goes on, less so).
As a player, despite the fact it was my first ever realm, I can't say that they aren't getting what they deserve at least in part. They've pushed Coria around before now, and I know for a fact that Saeculo has had arguments with them before. I believe Enri and Saeculo certainly discussed the apparant domination over Coria and it's foreign affairs.
I would never want to see them destroyed, just learn some humility. They certainly do deserve to be a world power however, their successful defence against such odds is testimony of that.
