This "adds" Switzerland to the Grand Campaign by sacrificing the Knights of St John and replacing some stuff with the data i found within the Actual Switzerland faction. I am not a seasoned modder so please tell me if i did anything wrong.
How to download: Open the zip file and click on "Swiss Mod," After that Click on "Extract to DATA." then extract the files into your "Data" in Empire and replace the files. Please use a clean install. Might work with mods that have minor changes.
Sorry if the files are too big, I am bad with modding so i just edited the vanilla files and didn't create any new files.
