Recently, I attended Balticon, where George R.R. Martin dropped a completely new chapter from The Winds of Winter on us: the long-awaited Damphair chapter. George actually offered the convention a choice: he could read the “Sons of the Dragon” (the extended cut of Aenys I and Maegor the Cruel’s history intended for Fire and Blood), the previously seen Mercy chapter, or the never-before-heard Aeron chapter (which had previously been offered at WorldCon 2011, but rejected in favor of Arianne II). By overwhelming applause, the assembly voted for Aeron, to which he warned us: “This is similar in character to Ramsay Bolton. You are some sick motherfuckers.” The attendees seemed to freely acknowledge the claim, and what followed was probably one of the most thrilling chapters I’ve had ever had the fortune of listening from any novel, easily as engrossing (albeit in a morbid sense) as the high climaxes of A Storm of Swords. George admitted that there might be some revisions, even substantive ones, between the reading we received and the final version that comes in the published book. However, even on its own, the chapter was spectacular. Many were in attendance, but I didn’t see a bored face in the room. This chapter was a while in the making, but every bit was as savory as it could possibly be.
As a note, this isn’t in perfect chronological order. I suggest going to this piece to read the notes from the con. This is organized by greater themes, not strict progression.
