The Cthulhu Mythos (クトゥルフ神話 Kutourufu Shinwa?) is the name given to the fictional universe, featured in the world of Toaru Majutsu no Index, in which the stories of H. P. Lovecraft (referred to as the "genius author" in the narrative) and other authors after his death are based. It has been used as a base for spells created by certain magicians who desired to see the world described in those stories.
Since the Cthulhu Mythos is a fictional universe, spells involving it are defined as creating something from nothing.
Many stories in the Cthulhu Mythos describe the rampages of evil gods (such as Cthulhu, Yog-Sothoth and Nyarlathotep) from the perspective of humans on the sidelines - in a sense, they are a catalogue of those evil gods. These evil gods are beings no human can handle, however they all have a point in common - they all gain their role and terror from the story they represent. Ceremonies and spells using these evil gods cannot ignore this story aspect and no matter how frightening, they cannot do anything once the story has come to an end, until the next story begins.
One prominent symbol of the Cthulhu Mythos, used in certain spells derived from it, is human flesh and blood.
When Lovecraft was writing the Cthulhu Mythos, one of the subjects he apparently used as reference material was the Forgotten God, one of the Magic Gods of the true Gremlin. In the process and aftermath however, fiction and nonfiction mixed together so badly that the Forgotten God's original form was completely forgotten.
At an unknown point after the first stories of the Cthulhu Mythos were published, magicians calculated how to recreate the despair-inducing events in them and created spells with that purpose. They compiled such spells in the Necronomicon, which was then released into the world.
A number of incidents relating the Cthulhu Mythos are reported to have occurred. These include a man attempting to use a jewel in a box to call in someone not of this world, a marriage scam artist sending someone a yellow medallion to have them meet an evil god and steal their inheritance and an old man trying to create an existence guarding a gate that would allow him to travel to another world.
One notable event occurred in the Pacific, three years prior to the current year on August 2nd, orchestrated by the magic cabal Dusk Waiting to Awaken. A ceremony attempting to summon R'lyeh caused 103 workers aboard the resource extraction ship Condor to go insane. However the ceremony, which would have wiped out the residents of every island within 1000 km had it succeeded, ultimately failed. The incident was initially thought to be sabotage aimed at causing diplomatic tension between England and America as well as the international competition over underwater resources. However after the discovery of magical symbols on the ship, England covered up the incident as being caused by rough weather and no land in sight pushing the sailors to their psychological limits, and installed a facility in the area, supposedly to calm the minds of those at sea but actually to keep an eye on where the ceremony took place.
Necessarius Special Admission Test SSEdit
Spells derived from the Cthulhu Mythos are the focus of the events that occur during the Amakusa's admission test for Necessarius. Magicians from Dusk Waiting to Awaken impersonate them in order to steal the Necronomicon.
Using the stolen Necronomicon and a barge in the Strait of Dover, the cabal's leader Arlands Darkstreet begins a ritual to summon R'lyeh. Though this is thwarted by the Amakusa, he succeeds in obtaining data which is transmitted to another group stationed at Stonehenge, who attempt to create the new spell Blank Paper. The leader of the Stonehenge group, Vase, then utilises Cthulhu Mythos-based magic while trying to fight off the Amakusa, before they were all suddenly dispatched by a surprise attack by Freadia Strikers.
Reference to the Cthulhu Mythos in the storyEdit
|Story Title||Author||Usage in Toaru Majutsu no Index|
|"The Call of Cthulhu"||H. P. Lovecraft||Arlands Darkstreet and the Dusk Waiting to Awaken try to recreate the events that transpire in the story in order to attain "inspiration" like the poets and artists in the story, as a means of breaking through a dead-end in their magic research by raising R'lyeh twice:
|"The Haunter of the Dark"||H. P. Lovecraft||
|"The Hounds of Tindalos"||Frank Belknap Long||A magician uses a pocket watch with an irregularly moving second hand to reflect light. When it hits a target a monster that looks less like a hound and more like a bear trap with four animal legs leaped towards the target. Its appearance in the Toaru Majutsu no Index sidestory where it appeared from a crack in the stones of the plain of Stonehenge and its general description in the narration is a likely reference to this creature.|
|"The King in Yellow"||Robert W. Chambers||
|"The Seven Geases"||Clark Ashton Smith||A magician uses a wire stronger than a violin string that was made by sewing together spider silk to attack a target. When it hits a target, a black shadow that resembles a giant spider appears before it. This is likely a reference to Atlach-Nacha, a spider-like Great Old One from the story.|
|"The Thing on the Roof"||Robert E. Howard||Vase uses a red-jewel which if it hits a target will then emit a pitch black darkness, which then absorbs the target completely, even absorbing their screams. The jewel represents the red jewel that is said to call in a frog-like evil god found in some story in the Cthulhu Mythos.|
|"The Whisperer in Darkness"||H. P. Lovecraft||A magician covers his skin in mold, and when a target touches the mold the magician makes a chant, at which point the mold becomes tentacles to attack the target. They are based off the Mi-go in the story, an alien race that is also known as the Fungi from Yuggoth. The magician uses them as a motif to strengthen himself in battle.|
|"Through the Gates of the Silver Key"||H. P. Lovecraft||In one of the incidents related to the Cthulhu Mythos that Itsuwa reads, one of them has an old man who tried to "create" an existence that was both guardian of the gate and the gate itself so he could travel to another planet. It is an obvious reference to the story where the aged protagonist meets an Entity, likely Yog-Sothoth who is described as the Gate and the Key, and requests him to take him to an alien planet.|
|At the Mountains of Madness||H. P. Lovecraft||The parasitic lifeform which was encountered by Patricia Birdway's research team in Antarctica, and subsequently attached itself to her, was named Sample Shoggoth, after the protoplasmic monsters known as Shoggoths featured in the story.|
