The narrator focuses primarily on his military recovery and the investigation, showing no romantic or sexual interests.

Strong cosmic horror and political subversion dominate the text. A major theme centers on the 'Restorationists' who view the ruling deities as soul-destroying, alien monsters rather than benevolent gods. The story explores themes of sanity, historical revisionism, and the blurry line between terrorists and freedom fighters.
