And frankly Caerwyn didnt stop many of our monster attacks those came steadily from barrowspeak upper/ lower via and beyond, until I took Lowervia and created a buffer when Caerwyn finally took Uppervia and fortress Via.
The very fact that Caerwyn existed kept the monster spawn down in vast areas of land. There are now an extra 12 or so rogue regions to your east, where all those nice monsters can spawn and attack you. The very fact that you're getting buried now should really show you how much Caerwyn was blocking.
