George R.R. Martin appeared at a science fiction convention in Baltimore this past weekend, where he shared an interesting biographical note about the knight Brienne of Tarth: she’s a descendant of Ser Duncan the Tall, who was, as you’d gather, very tall. (Seven feet, to be precise.)

Duncan predated the show’s timeline by about a century, and, as Esquire reports, he has a special place in Martin’s heart. The author has penned a collection of novellas about the knight.

At his Baltimore appearance, Martin also read a chapter from Winds of Winter, the long-awaited next book in the series.
