What mood is created through the narrator's description of London? Support your answer with textual proof.

London is described with an ominous sense to it. Throughout The Golden Compass, Pullman establishes an ominous and fantastical mood. To do so he often uses ancient, strange words to describe seemingly ordinary things. One example is the “chthonic railway.” Chthonic means underground, and usually refers to mythological underworlds. By referring to what appears to simply be a metro, or a subway system, with such a dark and loaded adjective, Pullman establishes the ominous mood of Lyra’s world.
