“Winter is coming.”

“A long summer always meant a long winter to come.”

“Because it will not last,” Catelyn answered, sadly. “Because they are the knights of summer, and winter is coming.”

“Winter is coming, and when the Long Night falls, only the Night’s Watch will stand between the realm and the darkness that sweeps from the North.”

“Because they are the knights of summer, and winter is coming.'' ''Lady Catelyn, you are wrong.'' Brienne regarded her with eyes as blue as her armor. ''Winter will never come for the likes of us. Should we die in battle, they will surely sing of us, and it's always summer in the songs. In the songs all knights are gallant, all maids are beautiful, and the sun is always shining.”

“Now you know " the crow whispered as it sat on his shoulder. "Now you know why you must live." "Why " Bran said not understanding falling falling. "Because winter is coming.”

“Still ... in this world only winter is certain.”
