The Pureborn, also known as the Enthroned, are descendants of the Qarth's ancient kings and queens, who rule the city of Qarth from the Hall of a Thousand Thrones. The Pureborn also command the city's defenses: the Civic Guard, which includes camelry, and a great military fleet. There are three principal merchant groups that battle amongst themselves and against the Pureborn for dominance of the city: the Thirteen, the Ancient Guild of Spicers, and the Tourmaline Brotherhood.
Robb Stark by Christopher Lair. “MY LORDS! Here is what I say to these two kings!...Why should they rule over me and mine, from some flowery seat in Highgarden or Dorne? What do they know of the Wall or the wolfswood or the barrows of the First Men? Even their gods are wrong....Why shouldn’t we rule ourselves again? It was the dragons we married, and the dragons are all dead! There sits the only king I mean to bow my knee to, m’lords. The King in the North!”
