On one hand, since monster hordes are what keep certain regions inaccessible, I see no reason why these hordes couldn't shift about.
I wonder if we could not reach of the same effects simply by moving the hordes around and shortening some of the sea routes rather than creating new lands? Like, instead of creating new rurals around Garuck Udor, remove the monster hordes from some of the rurals between Candiels ond Paisley on the coast and make them less 6 hours away from Garuck Udor by tweaking the sea zones.
