It's a really cool idea, Roran. But wouldn't an hypothetical monster invasion come from the north-west? Monsters were lately travelling to the western island through the north, which is connected by land, right?
I mean, it this "Night's Watch" is thought as a wall against monster invasions, maybe it'd be more reasonable to settle it in the north. If it's intended as a "beach's head" for realms to keep human presence in the west, I guess the locations proposed would work fine.
Hope to see it working soon!
