What is Kropplenburg?

Kropplenburg is the oldest city (albeit not the capital) of the fictitious Principality of Ruhnia, which is "situated" in the triangular corner between Germany, Austria and the Czech Republic. The City of Kropplenburg (Kropčahne in the native language) has a continuous history going back to Roman times and evidence of human settlement has been dated as far back as 8000 BC.

This description is obviously not finished and will be added to according to inspiriation.
