The short story that first mentions Cthulhu, "The Call of Cthulhu", was published in
Weird Tales in 1928, and established the character as a malevolent entity, hibernating within
R'lyeh, an underwater city in the
South Pacific. The imprisoned Cthulhu is apparently the source of constant subconscious anxiety for all mankind, and is also the object of worship, both by many human cults (including some within
New Zealand,
Greenland,
Louisiana, and the
Chinese mountains) and by other Lovecraftian monsters (called
Deep Ones and
Mi-Go). The short story asserts the premise that, while currently trapped, Cthulhu will eventually return. His worshippers chant "''Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn
("In his house at R'lyeh
, dead Cthulhu waits dreaming"). The short story "The Dunwich Horror" (1928) refers to Cthulhu, while The Whisperer in Darkness'' (1930) hints that one of his characters knows the creature's origins ("I learned whence Cthulhu first came, and why half the great temporary stars of history had flared forth.")
August Derleth, a correspondent of Lovecraft's, used the creature's name to identify the system of lore employed by Lovecraft and his literary successors, the
Cthulhu Mythos. In 1937, Derleth wrote the short story "The Return of Hastur", and proposed two groups of opposed cosmic entities: According to Derleth's scheme, "Great Cthulhu is one of the Water Elementals" and was engaged in an age-old arch-rivalry with a designated air elemental,
Hastur the Unspeakable, described as Cthulhu's "half-brother." In
John Glasby's "A Shadow from the Aeons", Cthulhu is seen by the narrator roaming the riverbank near Dominic Waldron's castle, and roaring. The character's influence also extended into gaming literature; games company
TSR included an entire chapter on the Cthulhu mythos (including character statistics) in the first printing of
Dungeons & Dragons sourcebook
Deities & Demigods (1980). TSR, however, were unaware that
Arkham House, which asserted copyright on almost all Lovecraft literature, had already licensed the Cthulhu property to game company
Chaosium. Although Chaosium stipulated that TSR could continue to use the material if each future edition featured a published credit to Chaosium, TSR refused and the material was removed from all subsequent editions. ==Influence==
