Quotes:

"He asked me to stop calling myself "Blackfish". Said it was an old joke, and it wasn't very funny in the first place....I told him people have been calling me "Blackfish" for so long, they don't remember my real name."

― Brynden Tully to his niece Catelyn Stark about her father Hoster Tully

"Peace. Peace is sweet, my lady ... but on what terms? It is no good hammering your sword into a plowshare if you must forge it again on the morrow."
