Y'know, nuance is still a thing.
"Very small realms are a problem" doesn't automatically mean "the larger your realm, the better."
I don't think that encouraging already-large realms to merge into behemoths is in any way, shape, or form the answer. Having a continent dominated by one or more behemoth realms is toxic to dynamic relationships on that continent—we saw that on Atamara. That's why we sank Atamara.
No, we want realms to be of moderate size: not too big, not too small, and with a reasonable amount of variability in sizes.
