During puberty, children's dæmons "settle" into a form which reflects their mature personality. In "Northern Lights" it is noted that most servants have dog dæmons (although a maid was noted with a hen dæmon), and all witches' dæmons take the form of a bird of some kind. In "La Belle Sauvage" Malcolm and Alice meet a woman they think of as a fairy who has a flock of butterflies rather than a single dæmon. At the beginning of the trilogy, Lord Asriel claims that the act of settling triggers Dust to begin to be attracted to the person.
