During the Hyborian Age, circa 10,000 BC, the Great Old One Cthulhu allegedly slumbered there, according to the eldritch language chant of the men of the sea worshiping Dagon: "Ph'nglui mglw'nafh Ctulhu R'lyeh wgah-ngal fhtaga!"
To avenge himself from Captain Dalvalte who tortured him, left him for dead and stole his daughters, Reimos allegedly entered in contact with many Old Ones, the Black Gods of R'Lyeh, who offered him his spider-infested castle.
War with Atlantis
When Doctor Strange weakened the barriers containing the Old Ones, a "thing from R'lyeh" was let loose and harassed Jacob Roark in his cabin where he had retired himself to meditate for five years, and whose greater magical potential had been awakened by the same event, and whose energies was the only thing holding the thing's shape. Roark eventually relinquished his magical potential on Strange's counsel, and the thing departed.
- R'lyeh is a fictional lost city that first appeared in the H. P. Lovecraft short story "The Call of Cthulhu", first published in Weird Tales (June, 1928).
- R'lyeh has inspired a few Marvel Comics locations, including:
- Magneto's island-base in the Bermuda Triangle, first appearing in Uncanny X-Men #147 (July, 1981), is believed to be (or to be based on) R'lyeh. Though the architecture on the island included octopus-headed statues and the inspiration for its design was clear, the island was never explicitly referred to as R'lyeh. It was possibly due to the uncertainty surrounding public domain status of some of Lovecraft's work.
- R'llyeh, in the Black Smokers' Trench of the Pacific Ocean, is obviously patterned after R'lyeh, and many matter related to R'llyeh are references to 'The Call of Cthulhu". The Logomancer stated that the Necronomicon, the Oracles of Zoroaster, the Darkhold and other mystic scrolls and books were in fact just imperfect copies of the ancient writings etched on the walls of R'llyeh produced by ancient beings.
- Carnage Vol. 2 features two locations analogous to R'lyeh, yet related to Chthon (an evil Elder God somewhat inspired by the Cthulhu Mythos and sometimes mentioned as one of the Great Old Ones):
- The Chthonic Island.
- K'lay was mentioned in the verse of the Darkhold "Ph'nglui mglw'naft Chthon K'lay wgah'nagl fhtagn", a revamping of the famous sentence "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn", a sentence from "The Call of Cthulhu", replacing Cthulhu and R'lyeh by Chthon and K'lay. Translated into English, the sentence reads "In his house at K'lay dead Chthon waits dreaming.
- In Doctor Who Magazine, then published by Marvel Comics, the story The Flesh Unbound (Doctor Who Magazine #221-#223; December, 1994-February, 1995; written by Alan Barnes and penciled by Adrian Salmon) of the umbrella title The Cybermen introduced a character named "R'lyeh", living on the planet Mondas.
- R'lyeh was originally written with a "l" minuscule letter. In comics, it is unknown how it is written (due to bubble texts being written exclusively in capital letters), but in the Demons' entry of the Marvel Zombies: The Book of Angels, Demons & Various Monstrosities #1, while mentioning the Black Gods of R'Lyeh, it is written "R'Lyeh", with a capital "L".
