“They held each other close and turned their backs upon the end. The hills that split asunder and the black that ate the skies; The flames that shot so high and hot that even dragons burned; Would never be the final sights that fell upon their eyes. A fly upon a wall, the waves the sea wind whipped and churned — The city of a thousand years, and all that men had learned; The Doom consumed it all alike, and neither of them turned" ―Tyrion Lannister and Jorah Mormont, quoting a poem about the Doom”
