What role does Faber play in fahrenheit451

Faber greatly disapproves of the dehumanized, oppressive society in which he lives. However, Faber feels it is safer to live discreetly rather than protest or attempt to change the world. Faber and Montag first met years ago in a park and after a long discussion about books, gave Montag his contact information. After Montag is taken in by the magic of books, he seeks Faber out and together, the two men try to work together against their oppressive society. When Montag is running from the law, Faber helps him escape. At the end of the novel, we are led to believe that Faber escapes the atomic bomb, as he had planned to catch an early bus out of the city.
