Try typing in the console placeatpc "Barilzar" 1,20,1. If that dosnt work try finding out what his ID is, and type that in in place of his name inside the quotes. You can probobly find his ID on the internet. Then you will get a diologue box, and he will try and kill you. Then you take the ring and keep going. The reason why just cheating the ring in didnt work is because the journal entry (which is what progresses you in the quest) is added upon you killing him, not obtaining the ring. Hope this helped
