I'm a little worried about the effects, particularly for Dwilight, though I assume they probably assume.
In the past, we've seen a number of west-east wars. I think it's been generally agreed that having as many neighbors as possible is a good thing, and that long linear continents are contrary to this. Indeed, Dwilight's halfs are so thin, that there are no realms side by side, save for Corsanctum which almost snuggles in between Morek and Swordfell anyways.
More people per realm, great, for sure. But even in the earlier days, when the whole north had a lot of people and grew, laterally, into a snuggle-fest, options quickly became limited for them.
