So wait, Vivienne is from the Free Marches? That explains the accent. I though Gwendoline Christie voiced her but now I'm just stumped.
Is it weird that my first though upon hearing that was "Oh, Vivienne is from the Free Marches, just like... nobody!"?
I mean seriously, the Hawkes, Aveline, and Merrill are from Ferelden, Anders is of course an Ander, Varric is from Orzammar, Isabela is from Rivain, and Fenris is from Tevinter. The only actual Marcher is Sebastian, the black sheep of DA2 companions. I feel like we spent a whole game there and learned nothing about the Free Marches as a culture.
