Fahrenheit 451 Granger and the exiles
by Ray Bradbury

Granger and his band are ostracized intellectuals. They help Montag escape the Mechanical Hound by provided him with a concoction that changes his scent. They are also part of a network of people who have memorized various works of literature. They underscore the idea that books have a strong connection to people, are more than ink and paper. At one point they refer to themselves, figuratively, as disciples of Christ (or rather those books of the Bible) and thus allowing for a reading of Montag as a Christ figure.
