Each participant was then put under cryogenic sleep in hopes of preserving the continued existence of mankind.

A collection of stories:

1. The Temple
The story is narrated as a “found manuscript” penned by Karl Heinrich, Graf von Altberg-Ehrenstein, a lieutenant-commander in the Imperial German Navy during the days of World War I. It documents his untimely end at the bottom of the ocean. Altberg begins by declaring that he has decided to document the events leading up to his final hour in order to “set certain facts” before the public, aware that he will not survive to do so himself.

2. The Hound
The story focuses around the narrator and his friend St. John, who have a deranged interest in robbing graves. They constantly defile crypts and often keep souvenirs of their nocturnal expeditions. Since they reside in the same house, they have the opportunity to set up a sort of morbid museum in their basement. Using the objects they collect from the various graves they have robbed, they organize the private exhibition. The collection consists of headstones, preserved bodies, skulls, and several heads in different phases of decomposition. It also included statues, frightful paintings, and a locked portfolio bound in tanned human-skin.

3. The Nameless City
The Nameless City, of the story's title, is an ancient ruin located somewhere in the deserts of the Arabian Peninsula, and is older than any human civilization. In ancient times, the Nameless City was built and inhabited by an unnamed race of reptiles with a body shaped like a cross between a crocodile and a seal with a strange head common to neither, involving a protruding forehead, horns, lack of a nose, and an alligator-like jaw. These beings moved by crawling; thus, the architecture of the city has very low ceilings and some places are too low for a human being to stand upright. Their city was originally coastal, but, when the seas receded, it was left in the depths of a desert. This resulted in the decline and eventual ruin of the city.
