A Clash of Kings – The Crypts
When the shadows moved, it looked for an instant as if the dead were rising as well. Lyanna and Brandon, Lord Rickard Stark their father, Lord Edwyle his father, Lord Willam and his brother Artos the Implacable, Lord Donnor and Lord Beron and Lord Rodwell, one-eyed Lord Jonnel, Lord Barth and Lord Brandon and Lord Cregan who had fought the Dragonknight. On their stone chairs they sat with stone wolves at their feet. This was where they came when the warmth had seeped out of their bodies; this was the dark hall of the dead, where the living feared to tread.
A Clash of Kings – Chapter 68 – Bran
Winterfell is burning , but Bran and company are alive. They were hiding in the crypts.
To me, this feels like a bookend to the first part of the series. Where the beginning of the book starts with Ned leading Robert Baratheon to the crypts with Winterfell at its height. Here we end with Winterfell destroyed with Bran, Hodor, and the Reeds finding shelter among Stark ancestors.
