How does the author use allegory in the novel, Termination Shock?

Stephenson often uses allegory in his writing to say one thing directly, while making another larger point about something else. Consider, for instance, the quote: “Frederika Mathilde Louisa Saskia’s new plane didn’t fly as high as the old one. The stratosphere was out of reach for her now; carried out wild schemes to change the climate, but not a place she would go” (698). Stephenson talks not only about the new plane that Saskia received as a gift from Fahr, but also of Saskia’s political reach since she abdicated her throne. Even though she was only a figurehead before, people still associated her title with power. Since Saskia had lost her title, she also is no longer invited to spend time with those in higher circles of power. She does not want to go there. She is happy with the position she has taken as an ambassador for those countries that depend on climate change to survive.
