Wheels of white cheese were set at every table, above and below the salt, and flagons of hot spice wine and chilled autumn ale were passed up and down the tables. Lord Wyman’s musicians played bravely and well, but harp and fiddle and horn were soon drowned beneath a tide of talk and laughter, the clash of cup and plate, and the snarling of hounds fighting for table scraps. The singer sang good songs, “Iron Lances” and “The Burning of the Ships” and “The Bear and the Maiden Fair,” but only Hodor seemed to be listening. He stood beside the piper, hopping from one foot to the other. The noise swelled to a steady rumbling roar, a great heady stew of sound.
