Listening to Durnehviir talk to you after you defeat him in DG, I noticed that it sounded a lot like the generic dragon voice (IE: like the ones that get raised out of the dragon mounds or like the odd dragon not aggressive to you but gets knocked out of the sky by aggressive enemy creep). I also noticed a lot of inflections very similar to Hermaeus Mora, who is known to be voiced by Wes Johnson, most known for the Generic Imperial Male voice, Sheogorath, and Lucien Lachance in Oblivion, as Mr. Burke and the Super Mutants in Fallout 3.

So is Wes Johnson also Durnehviir/Generic Dragon?
