In the books
In the Song of Ice and Fire novels Ghost is the quietest and stealthiest of the five wolf cubs. Whilst the other wolves are darker-coloured, Ghost is an albino and initially appears to be the runt of the litter, though he grows up to be as big as any of the others. However, Ghost is also the only wolf born with his eyes open. Jon finds him separated from the others. Ghost's like-but-unlike nature appeals to Jon as a kindred spirit. Ghost's appearance is said to resemble that of the faces found on heart trees in the North.
