His Dark Materials is set in a multi-world reality, with the action moving from one world to another. The story begins in an alternative world where all humans have animal companions called daemons, which are manifestations of the human soul. The series follows the life of a young girl named Lyra who is an orphan living with the scholars at Jordan College, Oxford. As in Pullman’s novel, Lyra discovers a dangerous secret that involves Lord Asriel and Marisa Coulter.
In her search for a missing friend, Lyra also uncovers a series of kidnappings and its link to a mysterious substance called Dust, which leads her on a journey of epic proportions and ultimately to other worlds. A witches’ prophecy links Lyra’s destiny to Will, a teenager from our world, who is himself being pursued by mysterious figures connected to his father.
