I suggest making one of the expedition's missions involve starting a revolution in Ventorum. You're all focusing on minor things... blowing up one city/island at a time. (
But let's make it a proper revolution... with "land to the workers" and electrification of the entire country.
For new states, we can add a continent/island to the north or south (if, of course, the mapmaker wants to expand their map, as I have repeatedly tried to do this myself but haven't succeeded), however
because of these reasons, I won't add Toxinus to the region.
