Victarion's accent via Roy Dotrice... ?

[Samson]

So I have a question- 

 

I have tried Googling it up and down the internet.  Tried searching other forums, waited awhile trying to see if it came up sometime, but I simply can't find the answer.

 

When Roy Dotrice reads Victarion Greyjoy, what accent is he using?

 

IE, what region of England or what dialect is that supposed to be?

 

I feel like I have heard people speak like that before in life but I can't put my finger on where, and I am interested in the accents and dialects of the UK- so , where is Victarion "from" according to Roy Dotrice?

 

Thanks!@!

I don't know but I'm sad that I'll never get to hear Victarion voiced by Dotrice ever again. He really gave the character an extra touch.
