Theremon 762 is trying to get an interview from Aton 77 regarding the collapse of civilization, which Aton and his colleagues at the university have predicted will occur in a few hours’ time. After some hesitation, Aton agrees to give Theremon the interview. This interview, with several digressions and interruptions, forms the bulk of the story.

The “Book of Revelations” of a religious organization, the Cult, claims that periodically a great darkness engulfs Lagash and then things called Stars appear in the sky that cause men to go mad. In the current scientific age, this theory is largely discredited, but Aton and other members of Sara Observatory have been claiming for the past few months that such an event will occur. They have constructed the Hideout and are now preparing to record the coming of the Darkness for the use of the refugees.
The major difference between Isaac Asimov’s planet Lagash and Earth is that Lagash orbits around a star that is part of a complex system of six stars. Regularly alternating nights and days are unknown on Lagash because there is almost always at least one sun in the sky. Lagash’s scientists have only recently analyzed this situation, beginning four hundred years previously, when Genovi discovered that Lagash orbited the star Alpha, replacing the older geocentric cosmology. Since then,...
