"The Temple" is a short story written by H. P. Lovecraft in 1920. 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. Altberg begins by declaring that he has decided to document the events leading up to his untimely end in order to "set certain facts" before the public, aware that he will not survive to do so himself. Like Dagon, The Temple is a nautical story with a World War I background. The theme of submerged cities with non-human worshipers recurs in Lovecraft's later works, most notably The Call of Cthulhu and The Shadow Over Innsmouth. A sort of sequel can be found in the form of a role-playing game The City in the Sea, where up to four characters must journey by submersible to the temple of the Mythos god Gloon (the malign force behind the events in "The Temple" whose human disguise is depicted by the ivory carving in that story) and end his threat to the human race. This game and its play mechanics may be found in Cthulhu Now, published in 1987 by Chaosium. The Lovecraftian adventure video game Prisoner of Ice (1995) also takes place in a submarine, but during World War II.
