I started out as teutonic order in 1399. Converted to Prussia. I own most of eastern Europe except the Balcans. In the north there is a large Sweden and some russian nations. To the east horde nations. I have made it a habit of going to war against the emperor (Austria) whenever I can. The reason is that the Austrians declared war on me several times to make me release vassals. This is very annoying and disrupting. So I made up my mind to destroy Austria no matter how long it takes. I have also grabbed about half of Germany. This seemed to go quite well and Austria is scattered all over. Wien is totally isolated from the adjacent austrian provinces. (I made them cede them.) But now I get the mission to make Riga wote for me as emperor. Only problem is that Im not even a member of the HRE.. Since I have pestered the empire alot the last 200 years I imagine getting in will be hard. (I have never found any option to join even before I started harassing Austria.) Should I just skip this mission? Another question: I have the option to form my own empire. Would that give me benefits in my current situation?
