Empires and the people who serve them make for compelling fiction because the stakes are clear and the moral questions are rarely simple. A soldier or an agent acting on orders from a powerful government is never just following a plot point. That character is also navigating a question about personal responsibility, about what it means to serve a system you did not design and may not entirely believe in. Science fiction has always been well positioned to explore those questions, because the distance of an imaginary setting gives both the writer and the reader a kind of freedom. You can examine power, colonization, surveillance, and the machinery of empire without the weight of a specific political conversation. The story can speak plainly, and the reader can hear it clearly.
