I, Cthulhu
"I, Cthulhu" is a short humorous story by fantasy author Neil Gaiman featuring H. P. Lovecraft's Cthulhu who is dictating an autobiography to a human slave, Whateley. The story reveals much about Cthulhu's 'birth' and early life.
Plot
Narrated to his dedicated servant Whateley, Cthulhu tells the story of his birth on the planet Khhaa'yngnaiih ("No, of course I don't know how to spell it. Write it as it sounds.") to a father who was eaten by his mother, and a mother who was subsequently eaten by Cthulhu himself. For a few thousand years, young Cthulhu, "the colour of a young trout and about four of your feet long", slunk through the swamps of his home planet, eating and avoiding being eaten.
Not long thereafter, Cthulhu's uncle, Hastur, suggests that they and "the boys" (fellow nameless, nightmarish horrors from the Cthulhu Mythos) go out, explore the cosmos, and have some fun. After a long argument, a plane of existence is decided upon.
After a short stint in Carcosa, Cthulhu is directed by The King in Yellow towards Earth in his search for a patch of the cosmos to rule over. Finding Earth to be rich in both swamps and cultists, Cthulhu makes himself comfortable - until the arrival of the Old Ones ("Banal little bureaucruds",) enforcing some kind of cosmic law, requires Cthulhu and his followers to leave the seas and move onto land.
