Hi Luriel!
I'm no pro at this, but I'm a native spanish speaker and I have a deep voice that can be either smooth or gruff. I think I can give life to characthers like Amok or Galazar maybe (I love them and I'm a fan of your game =P) so I hope it can help you!
Me puedes contactar en mgaete@hotmail.com
Saludos y éxito! =D
