[@LloydTurquoise] A Wall is very much what I had in mind. And to most Citizens of my more enlightened Citystate Vohemia most likely will be seen as the bottom of the world. That Wall might be called the Unseen Wall (Because no one actually likes to even look into that direction), and that side of the river would be the bad part of town, like with slums and military barracks and the suchlike. 

Yeah farmland is the reason to even have any streches of land at all to me XD
