"The Night's Watch is... well, there's the Wall. At the far northern border of the Seven Kingdoms, seven hundred feet high, three hundred miles long. They say it was raised eight thousand years ago, by Bran the Builder, with the help of giants and the Children of the Forest. Bran the Builder was a Stark, one of my forefathers in the Age of Heroes."

He takes a drink and continues, "That's the legend. In truth, whatever else there is to say about it, it's a great wall of ice. The Night's Watch guards it."

For the moment, he doesn't return to the dice game.
