I think it's at least three ex-Yugoslavian countries: Serbia, Croatia and Montenegro. Kosovo and Bosnia (due to the fact of its majority being Muslim) are part of Bosbakia and Macedonia is part of Haltenia (based on Greece).

About the country: my suggestion was to have a Facebook account. But, I have a solution and making it a special country (Oscor knows what I'm talking about). In other words, you can manage it via Wikia and we (Oscor and me) post the informations on Facebook. Approved?
