In Philip Pullman's "The Amber Spyglass," a message is conveyed that gyropters will come into use soon after the introduction of zeppelins. This highlights the technological advancements occurring in the narrative’s world, suggesting a progression toward more sophisticated means of transportation. The mention of these vehicles emphasizes the blend of science fiction and fantasy that characterizes Pullman's work.
The statement reflects not only the timeline of these innovations but also the adherence to directions from a higher authority, referred to as "the Lady." This underscores themes of power, control, and the interplay of forces at work in the story. Overall, the inclusion of such elements enriches the plot and contributes to the atmosphere of adventure and exploration.
