Maester Luwin is the one who delivers the letter from Lysa Arryn to Catelyn Stark, suspecting House Lannister of Jon Arryn's murder. Luwin looks after Bran when the young boy falls from the First Keep. After four days he tells Tyrion Lannister that he believes Bran will live.
Luwin is present when Catelyn accuses Ser Jaime Lannister of throwing Bran from the tower. He remarks that Bran is usually assured in climbing and that he knows every stone of Winterfell.
When Bran dreams that his father is in the crypts, it is Luwin who takes him down to see that no one is there. They find a distraught Rickon, who has had the same dream, and Shaggydog, who bites Maester Luwin. He takes the two back to his tower, and they talk about the Children of the Forest. Only to be interrupted by the wolves that begin to howl and Rickon starts to cry, before a bloody raven arrives. Maester Luwin reads the message that Lord Eddard Stark has been executed, and tells them that they must find a stone carver who knew their father's features.
