Ghost is an albino direwolf bonded to Jon Snow. He received his name because of his white fur and the fact that he never makes a sound. He is the litter-mate of Grey Wind, Lady, Nymeria, Summer, and Shaggydog. Like Jon, Ghost is an outsider amongst his family and quick to mature.
Jon Snow is the bastard son of Eddard Stark, by a mother whose identity is a source of speculation. He was raised by his father alongside his true-born half-siblings, but joins the Night's Watch when he nears adulthood. He is constantly accompanied by his albino direwolf Ghost.
