The great thing about the opening titles of Game of Thrones – other than the theme tune – is that it ensures viewers get a good understanding of the geography of Westeros, and beyond.
For this reason, the parallels with Britain are immediately clear. The northerners have northern accents. The capital is in the southeast. Across the Narrow Sea/English Channel lies another continent. And everything north of Hadrian's Wall is dark and full of terrors.
