Will Parry

Will Parry is the son of John Parry, an explorer, and of Elaine Parry, a woman who appears to suffer from mental health problems.

Will fails to remember his father, a former Royal Marine, who has not been heard of since he vanished on an expedition to the Arctic, and who we later learn has wandered into another world and is unable to find his way back.

Will becomes the companion of Lyra Belacqua, and also the bearer of the Subtle Knife, by winning a fight in the Torre Degli Angeli, in which he loses two fingers on his left hand. His dæmon is called Kirjava.
