Re: VOICE of DOOM
Graf von Grausam would be linguistical correct.But It would be better if you kept the von Grausom monicker, at least it would allow you claim that there is a small City of Grausom or so,especially since German Titles depend on Places.
The Baron of Terror could of course be a Nickname or so,but it is as unlikley as Graf von Grausam as a real Title (especially considering that the Nazis could not give away any real Titles).
