I much prefer split yourself to form a new realm kind.
I don't think Xavax needs to split. It's actually a very healthy realm. Just two cities and great noble density. They're good.
They don't even need to be pacified and prevented from warring neighbours.
To be a model progressive EC realm they just need to start being responsible in their wars, that's all. I can't speak for Perdan's leadership, but I'm sure Perdan will withdraw when Xavax shows it can continue the war in a responsible manner, which is not obliterating and consuming unfriendly neighbours.
