Dust (His Dark Materials)

In Philip Pullman's His Dark Materials and The Book of Dust trilogies, Dust or Rusakov particles are particles associated with consciousness that are integral to the plot. In the multiverse in which these trilogies are set, Dust is attracted to consciousness, especially after puberty; the Church within the series associates Dust with original sin and seeks its end. Pullman described Dust in an interview as "an analogy of consciousness, and consciousness is this extraordinary property we have as human beings".
