Catalog

This bestiary lists every species of the Mythos available for simulation in stdvoidsim. Each has made-up but population-genetically plausible genomes and demographic histories. You can run simulations with a variety of demographic models for Lovecraftian entities from the Cthulhu Mythos.

This catalog shows you all of the possible options that you can use to configure your simulation. It is organised around a number of choices that you’ll need to make about the Species you wish to simulate:

  1. Which chromosome (Genome object)?

  2. Which model of demographic history (DemographicModel object)?

For instance, suppose you are interested in simulating Deep One samples under an Innsmouth Decline demographic model:

$ stdvoidsim DagHyd -d InnsmouthDecline_1M27 -o deep_ones.trees -L 100000 DeepOnes:10

Outer Gods & Great Old Ones

Azathoth (the Blind Idiot God) is the supreme deity of the Cthulhu Mythos, dwelling at the center of ultimate chaos. It is a boundless, amorphous entity of colossal size, described as a “nuclear chaos” surrounded by a retinue of mindless dancers and the thin monotonous piping of a demonic flute. Azathoth is effectively the ruler of the Outer Gods, yet is blind and idiotic, unaware of its own existence or the cosmos it spawned. All of reality is said to be merely Azathoth’s dream. First appearing in Lovecraft’s fiction in 1922, Azathoth embodies the ultimate horror of a universe governed by mindless, purposeless forces.

Great Cthulhu is perhaps the most iconic entity of the Mythos, a cosmic being of immense power who lies “dead but dreaming” in the sunken city of R’lyeh, deep beneath the Pacific Ocean. Described as a gigantic creature with an octopoid head, dragon-like wings, and a massive humanoid body, Cthulhu stands hundreds of meters tall. It communicates telepathically, sending dreams and visions to sensitive minds across the globe. Cthulhu is worshipped by hidden cults worldwide who chant “Ph’nglui mglw’nafh Cthulhu R’lyeh wgah’nagl fhtagn” – “In his house at R’lyeh, dead Cthulhu waits dreaming.” First appeared in “The Call of Cthulhu” (1928).

Chaugnar Faugn (the Feeder) is a Great Old One resembling a vampiric elephant-like humanoid horror. Created by Frank Belknap Long in The Horror from the Hills, the entity has a proboscidean trunk ending in a horrible lamprey-like mouth used to drain victims of blood and life essence. Though often illustrated as an anthropomorphic elephant, it is actually described as reptilian in nature, bearing only superficial resemblance to an elephant. It stands roughly eight feet tall with webbed, tentacled ears and enormous translucent tusks. When hungry, Chaugnar moves with surprising speed. Its servitors, the Miri Nigri, are the progenitors of the Tcho-Tcho people through hybridization with humans.

Father Dagon is an immensely large and powerful Deep One, worshipped as a deity by both the Deep Ones and certain coastal human cults. Together with Mother Hydra, Dagon rules over the Deep One civilization from the depths of the ocean. Described as a colossal fish-frog hybrid towering over even the largest Deep Ones, Dagon is ancient beyond human reckoning. Lovecraft introduced Dagon in his 1917 short story “Dagon,” one of his earliest tales, in which a shipwrecked sailor encounters the titanic creature on a newly risen island of black, slimy mud.

Hastur (the King in Yellow) is an enigmatic Great Old One associated with entropy, decay, and madness. The entity is connected to the mysterious play The King in Yellow, a forbidden text that drives readers to insanity. Hastur dwells near the star Aldebaran, close to the dark city of Carcosa by the shores of the Lake of Hali. Those who speak Hastur’s name risk drawing its attention. Originally created by Ambrose Bierce and developed by Robert W. Chambers, Hastur was later incorporated into the Cthulhu Mythos by Lovecraft and especially August Derleth, who elevated Hastur to a Great Old One rivaling Cthulhu.

Nyarlathotep (the Crawling Chaos) is unique among the Outer Gods in that it actively interacts with humanity, taking on a thousand different forms. Unlike the other Outer Gods, Nyarlathotep appears to be fully sentient and even enjoys spreading madness and destruction. Among its many avatars are the Black Pharaoh, the Haunter of the Dark, and a tall, swarthy man who walks among mortals. It serves as the messenger and soul of the Outer Gods, carrying out their will on Earth. First mentioned by Lovecraft in a 1920 prose poem, Nyarlathotep appears in numerous stories and is one of Lovecraft’s most developed creations.

Shub-Niggurath (the Black Goat of the Woods with a Thousand Young) is an Outer God associated with fertility, growth, and hideous fecundity. Though never directly described by Lovecraft, Shub-Niggurath is referenced frequently in incantations and rituals. It is a perverse fertility deity, spawning vast numbers of monstrous offspring known as the Dark Young. The entity exists in a cloudy, forested dimension and is worshipped by cults that invoke it with the chant “Ia! Shub-Niggurath!” Lovecraft first mentioned Shub-Niggurath in “The Last Test” (1928) and referenced it in several subsequent stories.

Tsathoggua is a Great Old One originally created by Clark Ashton Smith, later adopted into the Cthulhu Mythos by Lovecraft. Described as a furry, toad-like entity with sleepy eyes and a bat-like visage, Tsathoggua dwells in lightless caverns beneath Mount Voormithadreth in Hyperborea (and later beneath North America). It is notably lazy and slothful, preferring to lie in torpor and wait for sacrifices to be brought to it. Despite its apparent lethargy, it is immensely powerful. Its worship predates humanity, having been venerated by the Voormis and other prehuman races. First appeared in Smith’s “The Tale of Satampra Zeiros” (1931).

Yog-Sothoth (the Key and the Gate) is an Outer God that exists simultaneously in all of time and space, coterminous with all things. It appears as a conglomeration of iridescent, ever-shifting spheres or globes. As the “Key and the Gate,” Yog-Sothoth is the guardian of the threshold between dimensions, and those who seek to open the way between worlds must deal with it. It knows all and sees all, past, present, and future. Unlike Azathoth, it is fully cognizant. In “The Dunwich Horror” (1929), it is revealed as the father of the monstrous Wilbur Whateley and his invisible twin. Yog-Sothoth is one of the most powerful entities in the Mythos.

Servitor Races & Engineered Species

Byakhee are interstellar servitor creatures associated with Hastur and the King in Yellow. They can fly through space and between dimensions, carrying riders through the void. Described as a composite creature with bat-like wings, insectoid features, and a vaguely avian body, the Byakhee are not native to Earth. They possess an organ containing a substance called “space-mead” that allows them to survive the vacuum and cold of interstellar space. They can be summoned on certain nights using particular rituals. First described by August Derleth, the Byakhee serve as steeds for those traveling to Carcosa or other far-flung cosmic destinations.

Dark Young of Shub-Niggurath are monstrous tree-like entities spawned by the Outer God Shub-Niggurath. They appear as enormous, black, ropy, tentacled masses with multiple goat-like hooves at their bases, resembling a nightmarish fusion of tree and animal. They stand roughly 20 feet tall. Despite their plant-like appearance, they are intelligent and serve as intermediaries between Shub-Niggurath and her worshippers. Dark Young inhabit dark forests and woodlands, and are summoned during rituals to the Black Goat. They emit a sickly sweet smell and crush victims beneath their hooves or grasp them with their tentacles.

Fire Vampires are living extensions of the cosmic entity Fthaggua, created by Donald Wandrei for “The Fire Vampires” and later incorporated into the Cthulhu Mythos. They appear as reddish electrical discharges resembling lightning, traveling the cosmos aboard the interstellar comet Ktynga. Fire Vampires feast upon the life energy and memories of sentient creatures, causing their victims to burst into flames during the feeding process. Their leader, Fthaggua, appears as a great flickering ball of cold blue flame and serves as high priest of Cthugha. The knowledge accumulated from slain beings allows Fthaggua to better locate and hunt intelligent civilizations across the cosmos.

Formless Spawn are the amorphous servitors of Tsathoggua, dwelling in the lightless caverns beneath Mount Voormithadreth and other subterranean locations. They are black, protoplasmic entities that can assume virtually any shape, from tentacled horrors to serpentine forms. In their natural state, they appear as pools of living blackness. Unlike shoggoths, they are naturally occurring beings rather than engineered creatures. Formless Spawn guard the sleeping form of Tsathoggua and attack anything that approaches their master without proper obeisance. They were first described by Clark Ashton Smith in “The Tale of Satampra Zeiros” (1931).

Hunting Horrors are nightmarish serpentine creatures that serve Nyarlathotep. They resemble enormous, jet-black serpents or worms with bat-like wings, and their forms seem to shift and writhe in a way that defies clear perception. They pursue their prey relentlessly through the skies and even through the void between worlds. Hunting Horrors are vulnerable to light, particularly sunlight, which can destroy them. They are most commonly encountered in the Dreamlands, where they hunt on behalf of the Crawling Chaos. Lovecraft referenced these creatures in The Dream-Quest of Unknown Kadath (1927), where protagonist Randolph Carter encounters them in the skies.

Shoggoths are massive amoeba-like creatures originally bioengineered by the Elder Things as versatile construction workers and servants. Described as protoplasmic, iridescent black masses roughly 15 feet across, shoggoths can form any organ, limb, or sensory apparatus at will. Multiple luminous green eyes float on their surfaces. Originally mindless, the shoggoths gradually developed intelligence over millions of years and eventually revolted against their Elder Thing masters – a catastrophic rebellion that contributed to the decline of Elder Thing civilization. Their cry of “Tekeli-li!” is one of the most chilling sounds in the Mythos. First described in At the Mountains of Madness (1936).

Star-Spawn of Cthulhu are gigantic octopoid beings that closely resemble Great Cthulhu himself, though smaller in stature. They accompanied Cthulhu when he descended from the stars to Earth, and helped build the cyclopean city of R’lyeh. When R’lyeh sank beneath the Pacific, most Star-Spawn were trapped alongside Cthulhu in his deathless slumber. However, some are believed to still roam the deepest ocean trenches, tended by the Deep Ones. They possess considerable telepathic abilities and are nearly as resilient as their master. Lovecraft described them in At the Mountains of Madness as the enemies of the Elder Things in ancient wars for dominion of the Earth.

Ancient Civilizations

Elder Things (also known as the Old Ones or Elder Ones) are the first extraterrestrial species to have colonized Earth, arriving approximately one billion years ago. They stand roughly eight feet tall with an oval, barrel- shaped body exhibiting five-fold radial symmetry. The top appendage is a head adorned with five eyes, five eating tubes, and a set of cilia for perceiving without light. The bottom appendage has five limbs used for locomotion. Five leathery, fan-like retractable wings and five sets of branching tentacles sprout from their torsos. Their blood is dark green, and their metabolism is based on carbon dioxide rather than oxygen.

The Elder Things can withstand the pressures of the deepest ocean, survive interstellar travel, and hibernate for vast epochs. They are amphibious and reproduce via spores. On Earth they built enormous cities both underwater and on land, and their civilization was extraordinarily advanced – they are credited with creating eukaryotic cells and thus all complex life on Earth. Most significantly, they bioengineered the shoggoths as construction servants, a decision that ultimately led to catastrophic revolts. Their society had no families (since they reproduce via spores) and their architecture reflects their five-pointed anatomy. First appeared in At the Mountains of Madness (1936).

Flying Polyps are a terrifying race of partially material beings that came to Earth from space approximately 750 million years ago. They are largely invisible, betrayed only by the great winds they generate and their five-pointed footprints. When partially visible, they appear as enormous, semi-transparent, tentacled horrors with multiple temporary eyes. Flying Polyps wield power over wind and can generate devastating aerial attacks. They were driven underground by the Great Race of Yith, who imprisoned them in vast subterranean caverns. However, the Polyps eventually rose up and destroyed the Great Race’s terrestrial civilization. Lovecraft described them in “The Shadow Out of Time” (1936).

Mi-Go (Fungi from Yuggoth) are an extraterrestrial species resembling crustacean-fungoid hybrids. About five feet long, they have multiple pairs of limbs, large membranous wings, and a head covered in antennae that constantly shift color to communicate. Despite their wings, they fly through space using means unknown. The Mi-Go have established colonies on Pluto (which they call Yuggoth) and mine rare minerals from Earth’s mountains, particularly in Vermont and the Himalayas. They are scientifically advanced, capable of removing human brains and placing them in metal cylinders for transport across space. Unlike most Mythos creatures, Mi-Go are composed of matter not native to our part of space and cannot be photographed. First appeared in “The Whisperer in Darkness” (1931).

Serpent People (of Valusia) are an ancient reptilian race that predates humanity by millions of years. Once the dominant civilization on Earth during the Paleozoic and Mesozoic eras, they built great cities and mastered powerful sorcery. Serpent People are shape-shifters capable of assuming human form, and they have infiltrated human societies throughout history. Their original empire of Valusia was overthrown by the barbarian king Kull. Despite their decline, small enclaves persist in hidden subterranean cities. They worship the serpent god Yig and possess advanced knowledge of alchemy and dark magic. Originally created by Robert E. Howard in his Kull stories, they were later incorporated into the Cthulhu Mythos.

Great Race of Yith are one of the most remarkable species in the Mythos – not for their physical forms, but for their mastery of time. The Yithians are minds, not bodies: they project their consciousnesses across time and space, swapping minds with other beings to inhabit their bodies. On Earth, they occupied the cone-shaped bodies of a species that lived roughly 250 million years ago, building a vast library-city in what is now Australia. Their great library contained knowledge gathered from all eras of history, as visiting Yithian minds recorded everything they learned. They were eventually destroyed by the Flying Polyps they had imprisoned underground. The surviving Yithian minds then projected themselves far into the future, into the bodies of a beetle-like species. First appeared in “The Shadow Out of Time” (1936).

Colour Out of Space is an extraterrestrial entity or force of unknowable nature that arrived on Earth via meteorite. The Colour exists on a part of the electromagnetic spectrum imperceptible to humans, appearing as an indescribable hue. After impact, it seeps into soil and water, corrupting the surrounding environment. Vegetation grows lush but bitter and unwholesome; animals are born deformed and driven mad; and humans exposed to it slowly wither, their skin graying and cracking as their life force is drained. The Colour’s life cycle involves germinating, leeching energy from a local ecosystem, and eventually departing the planet for space. It is perhaps Lovecraft’s most alien creation – a being with no physical form, no clear intelligence, and motives entirely beyond human comprehension. First appeared in “The Colour Out of Space” (1927).

Deep Ones are effectively immortal, growing larger and more powerful with age, and only dying through violence or accident. They worship Father Dagon, Mother Hydra, and Great Cthulhu. Most infamously, Deep Ones can interbreed with humans, producing hybrid offspring that initially appear human but gradually undergo a transformation (the “Innsmouth Look”) as they age, eventually becoming fully aquatic. The coastal town of Innsmouth, Massachusetts was the site of extensive Deep One–human hybridization. First appeared in “The Shadow Over Innsmouth” (1936).

Two-population model representing pure oceanic Deep Ones and coastal/terrestrial Innsmouth Hybrids. An ancestral Deep One population of size 200,000 gives rise to the Hybrid population 30 generations ago via a founder event (initial size 50). The Hybrid population expands to 5,000 in the present day. The Deep One population declines from 200,000 to 50,000 at the time of the Innsmouth raid 3 generations ago.

Subterranean Horrors

Dholes are colossal burrowing worm-like entities of immense size that inhabit the underworld of the Dreamlands, particularly the Vale of Pnath. They are so enormous that they can be mistaken for geographical features – their bodies stretch for miles through the earth. Dholes are slimy, pale, and virtually featureless, with gaping maws. They burrow through both the Dreamlands and the waking world, and their passage leaves great tunnels and caverns. Little is known about their intelligence or motivations. They are among the most dangerous creatures in the Dreamlands, and even other Mythos entities give them a wide berth. Lovecraft mentioned them in The Dream-Quest of Unknown Kadath (1927).

Ghasts are large, kangaroo-like humanoid creatures that inhabit the underworld caverns of the Dreamlands, particularly the Vaults of Zin. They are roughly human-sized but with bestial features, including elongated limbs and a vaguely canine face. Ghasts are savage predators that hunt in packs and will devour anything they can catch, including ghouls. Their one great weakness is light – they cannot endure even the faintest illumination and flee from it in terror. Ghasts hop rather than walk, using their powerful hind legs. Despite their ferocity, they are preyed upon by the even more terrible gugs. Lovecraft described them in The Dream-Quest of Unknown Kadath (1927).

Ghouls are humanoid creatures that feed on the flesh of the dead. In Lovecraft’s Mythos, ghouls are not undead but a distinct species – rubbery, loathsome beings with canine features, hooved feet, and mold-caked skin. They dwell in vast warrens of tunnels beneath cemeteries and in the underworld of the Dreamlands. Remarkably, some ghouls were once human: certain individuals who develop a taste for human flesh gradually transform over time into ghouls. Despite their horrific diet and appearance, ghouls possess intelligence and even a crude society. In The Dream-Quest of Unknown Kadath, they prove to be valuable allies. Richard Upton Pickman, the artist from “Pickman’s Model” (1927), eventually completed his transformation into a ghoul.

Gugs are gigantic, hairy, barrel-shaped creatures that inhabit the Dreamlands underworld. They stand roughly 20 feet tall, with enormous arms ending in paws that have vertical mouths running from wrist to elbow. Their heads bear a single pair of pink eyes and a wide, fanged mouth. Gugs were banished from the surface of the Dreamlands to the underworld for committing some unnamed blasphemy against the Great Ones. A massive stone trapdoor in the Enchanted Wood marks the boundary they are forbidden to cross. Despite their fearsome appearance and strength, gugs possess a crude civilization and worship dark gods. They prey on ghasts and anything else they can catch. First described in The Dream-Quest of Unknown Kadath (1927).

Wamps are subterranean creatures from the Mythos, dwelling in deep cave systems and underground passages. These lesser-known entities are predatory and adapted to a lightless existence, hunting by sound and vibration in the eternal darkness of the deep earth. They are generally hostile to surface dwellers and other subterranean races alike, defending their territory with ferocity.

Dreamlands Creatures

Cats of Ulthar are the felines of the Dreamlands city of Ulthar, where by ancient law no man may kill a cat. This law was established after an old couple who delighted in killing cats made the mistake of taking in a kitten belonging to a traveling orphan boy. The boy prayed to the mysterious gods of the Dreamlands, and that night all the cats of Ulthar gathered and descended upon the couple. In the morning, nothing remained of the pair but two cleanly picked skeletons. The cats of Ulthar are intelligent, organized, and capable of collective action. They can leap to the moon and travel throughout the Dreamlands. First appeared in “The Cats of Ulthar” (1920).

Leng Spiders are gigantic arachnids that inhabit the cold, desolate Plateau of Leng in the Dreamlands. They are bloated, purple-bodied spiders of extraordinary size – smaller specimens are the size of ponies, while the largest can tower over elephants and weigh many tons, as Leng Spiders never stop growing. They are highly intelligent, spinning webs of incredible strength with strategic cunning rather than instinct. Leng Spiders are solitary predators that will even prey on their own kind. Their venom induces deep sleep, after which victims are dragged to the spider’s lair to be consumed or used as hosts for eggs. They are thought to be the children of Atlach-Nacha, the spider god. Once rulers of the Leng plains, they were driven to gorges and caves by the people of Leng. First appeared in The Dream-Quest of Unknown Kadath (1927).

Moon-Beasts are the bloated, toad-like creatures that inhabit the dark side of the Dreamlands’ moon. They are pale, amorphous, almost faceless beings with small red tentacles or feelers where a face should be. Moon-Beasts are cruel slavers who sail black galleys crewed by their servants, the Men of Leng, and trade in slaves captured from the Dreamlands’ ports and cities. They serve Nyarlathotep and maintain a trade network that extends across the Dreamlands. Their galleys are distinctive and feared. Moon-Beasts are physically soft and relatively weak individually, but dangerous in groups. First described by Lovecraft in The Dream-Quest of Unknown Kadath (1927).

Nightgaunts are faceless, black, rubbery, winged humanoid creatures that inhabit the Dreamlands. They are lean and slippery, with bat-like wings, horned tails, and inward-curving horns on their heads. Their most distinctive and unsettling feature is their complete lack of a face – where features should be, there is only smooth, blank darkness. Nightgaunts attack by tickling their victims into helplessness, then carrying them off through the air. Despite their terrifying appearance, nightgaunts are not inherently evil and can sometimes be allied with. They guard the slopes of the Dreamlands’ highest peaks and serve Nodens, Lord of the Great Abyss. Lovecraft dreamed of nightgaunts as a child, and they appeared in The Dream-Quest of Unknown Kadath (1927).

Shantaks are enormous bird-like creatures from the Dreamlands, larger than elephants, with the body of a horse and the head of a horse combined with bat-like wings. Their skin is described as slippery and scaly rather than feathered. Shantaks serve as aerial mounts in the Dreamlands and are used by various beings for transportation across vast distances. Despite their great size and power, shantaks are terrified of nightgaunts, who can easily overpower them. They nest on the peaks of the tallest mountains in the Dreamlands and are sometimes tamed by inhabitants of the Plateau of Leng. First described in The Dream-Quest of Unknown Kadath (1927).

Zoogs are small, brown, mouse-like creatures that inhabit the Enchanted Wood of the Dreamlands. They are furtive, secretive beings roughly the size of a rat, with sharp teeth and a taste for mischief. Though individually insignificant, zoogs are numerous and organized into a loose tribal society led by elders. They are omnivorous and have been known to attack travelers in large groups. Zoogs are cunning negotiators and possess considerable knowledge of the Dreamlands, making them useful (if unreliable) sources of information. They maintain an uneasy truce with the cats of Ulthar, who are their natural enemies. First appeared in The Dream-Quest of Unknown Kadath (1927).

Interdimensional & Temporal

Dimensional Shamblers are interdimensional predators that move between planes of existence. They appear as roughly humanoid but deeply wrong – with coarse, wrinkled skin, long arms ending in enormous crab-like claws, and a hunched, ape-like posture. Their heads are featureless except for a mass of short, writhing tentacles where the face should be. Dimensional Shamblers can step between dimensions at will, appearing and disappearing without warning. They seize their prey and drag them into other dimensions from which there is no return. They were first described in “The Horror in the Museum” (1933), a story ghost-written by Lovecraft for Hazel Heald.

Hounds of Tindalos are extradimensional entities that inhabit the “angles” of time, as opposed to the “curves” in which normal life exists. They are lean, filthy creatures of alien geometry, described as having long, hollow tongues through which they drain their victims. The Hounds can materialize through any sufficiently sharp angle – corners of rooms, edges of furniture – anywhere that angles of 120 degrees or less exist. Once a Hound has the scent of its prey (typically someone who has traveled through time or used certain drugs), it will pursue relentlessly across any distance or dimension. The only protection is to be in a room with no angles – a perfectly curved space. They are believed to be among the oldest entities in existence. First appeared in Frank Belknap Long’s “The Hounds of Tindalos” (1929).

Arctic & Desert

Gnoph-Keh are fearsome arctic creatures resembling six-legged polar bears with coarse, matted white hair and a single large narwhal-like horn. They possess the ability to summon blizzards and drastically reduce temperatures in their vicinity. Gnoph-Keh are territorial, solitary, and now extremely rare, dwelling in Greenland and the Arctic Circle. In the earliest texts (such as the Book of Eibon), the Gnoph-Keh were described as a race of vicious cannibals driven from the land of Lomar by mankind and the Voormis. They are connected with Rhan-Tegoth and possibly with Ithaqua, the Wind-Walker. Legend suggests they are the remnants of a lost tribe that turned from earthly gods to serve Ithaqua, becoming something other than human.

They resemble thin, sand-encrusted humans with unusually large eyes and ears, and faces that look somewhat like those of koalas. Sand Dwellers dwell in caves during daylight and emerge at night in groups to hunt. They are associated with at least one large tentacled creature of unknown nature. In some interpretations they are literally made of sand and can combine into larger forms, while in others they are psychic parasites that grow inside the minds of their victims before manifesting physically.

Human-Adjacent Horrors

Rat-Things (such as the infamous Brown Jenkin) are hybrid creatures with the body of a rat and a disturbing, miniature human-like face with sharp teeth. Brown Jenkin, the most famous rat-thing, served the witch Keziah Mason and could pass through dimensional barriers along angles that correspond to alien geometries. Rat-Things are familiar spirits of witches, carrying out errands between dimensions and assisting in dark rituals. They are disturbingly intelligent, possessing human-level cunning in a rodent body. Their small size makes them difficult to catch or kill, and their ability to move between dimensions makes them impossible to trap by conventional means. First appeared in “The Dreams in the Witch House” (1933).

Tcho-Tcho are a species of near-human beings native to Asia, found in Burma, Tibet, Malaysia, and the Andaman Islands. Created by August Derleth and Mark Schorer, they are notably small (rarely exceeding four feet in height), with dome-shaped heads, small deep-set eyes, and livid skin. Despite their small stature, they are surprisingly strong. The Tcho-Tcho are believed to have been spawned through the genetic manipulation of pre-human ancestors by the Great Old Ones Zhar and Lloigor, with further connections to Chaugnar Faugn through the Miri Nigri. They worship various Great Old Ones including Hastur, Chaugnar Faugn, and Rhan-Tegoth. They are notorious for their cannibalistic practices and hostility toward outsiders. Lovecraft referenced them in The Shadow Out of Time (1936).
