Well, you certainly wouldn't catch me complaining if it were to split up into 2 or 3 realms...
The trouble with something like that, as is often the case, is creating a believable IC rationale and getting the IC political will and clout behind it.
That's kind of what I was trying to achieve in Arcaea - polarise matters religiously so that the two Sartanian dukes split off to create a new realm, thereby splitting Arcaea in two and creating the opportunity for conflict.
Because, as it is, Arcaea's geography means it would win pretty much any war but one where almost every single other realm ganged up on it.
