Meh, regardless of whether you requested it already, i should give him my two cents on Dvakvar Grahrk.
Ok so, Dvakvar didnt have anything written for him in the game files. But the upside is, you could just use the standard devaronian voices for him. Also the party didnt have anything voiced regarding him either, so that would breed difficulties when tryng to make ebon hawk cutscenes. I forgot to mention he does have text files, just nothing else lol. I could give this a try, but I personally suck with creating scripts, so i would need some people to help me.
