The demon crashed through the refectory roof before dawn. Metallic, with six wheels, it had a glass eye on top of a hinged arm. I read the word MARINER inscribed on the demon’s side. Now that I knew its name I could command it.
I demanded MARINER go back to its own hellish world. At that, it rolled out the wide doors, through the courtyard, then at the crossroads it scanned the sky until it eyed the morning star.
Then the demon turned and trundled off in the direction of Venus.
