When winter comes... You'll hear no lions roar... No stags grazing the fields... No roses growing in the meadows... No snakes in the sand... The krakens will freeze where they swim... The flayed men will rot and wither... No trouts swimming in the river and no falcons flying in the air... Not even the dragons breath will warm you in your halls. Only the wolfs howl in the night... Winter is coming.
Brynden Tully, the Blackfish. "During one of their louder quarrels, when Catelyn was eight, Lord Hoster had called Brynden 'the black goat of the Tully flock.' Laughing, Brynden had pointed out that the sigil of their house was a leaping trout, so he ought to be a black fish rather than a black goat, and from that day forward he had taken it as his personal emblem."
