Civilization's Cycle

Hard times create strong men.
Strong men create good times.
Good times create weak men.
Weak men create hard times.
Such is the cycle of all civilized peoples, and what affected Hooman civilization affected its Guardian. When societies prospered, so did She. Likewise, strife afflicted Her, regardless of whether it was brought about by subjugation, plague, famine, or degeneracy.
This link between Hooman civilization and the Nameless One is well-documented and reciprocal. When She wavered, stagnation occurred and criminal activity rose. When social order broke down, Her abilities waned and She became similarly corrupted. The Pestilence of Kyun from which the Nameless One never fully recovered is believed to have occurred as a result of this cycle spiraling further than She could handle.
As a sort of cosmic safeguard against further feedback loops, the Nameless One would purge Herself of corruption, jettisoning it from Her essence and giving it its own form and identity. Doing so has the drawback of destroying the Nameless One's physical form, reducing Her essence to that of a small and pale spirit that cannot be corrupted. She does gradually re-manifest Her body as civilization recovers, but it is a far from fast process that sees Hooman society wracked with hardship.
It is during these times of strife that their worship of Her is perhaps the most fervent, as it is generally believed by Hoomanity that the acts of the worshippers influence their Gods. Even with the connection between Her purity and the state of Hooman civilization having severed as a result of the apothnitosis, worship in times of strife remains strong.

Introduction: Nameless Mother of a Thousand Young
The Nameless One was an avatar of Civilization itself, so when civilizations became weakened or corrupted, so did She. To avoid losing Herself in those dire times, She purged the corrupt aspects of Herself from Her essence, giving them physical form. Many of the terrible creatures described in horrific detail throughout the Nameless Mythos are said to have spawned from this process. The entities described below are the more recognizable exceptions to this.
Though the creatures spawned from this process are said to be both maddening to behold and destructive in nature, the Nameless One is said to view them in the same way a mother sees her children. A common folk tale is that, on a certain day of the year, She takes them all "out to play", bringing them out of the Heavenly Layer to wander around Viti. Due to the sheer amount of these creatures the Nameless One has spawned, those same tales claim that some were mistakenly left behind, resulting in various nightmarish entities scouring Viti in search of their Mama to take them home.
The Meem

One may assume that Hoomans on their deathbeds say they are approached by the Nameless One's Grand Hoot to escort them from their mortal coils in their final moments. In truth, this is not the case. None of those who wrote down their final moments for posterity or for memorialization have had dying visions of him coming for them, not even the most devout Morbs or archivists.
If anyhoot writes or speaks of an otherworldly entity approaching them in their dying moments, it is a different figure entirely: the Meem.
Though the Meem's status as an otherworldly entity is not officially corroborated in any preserved texts, the numerous testimonial accounts of a being strongly resembling the Nameless One being present in one's dying moments has led to a general acceptance of her existence.
As mentioned, the Meem's general appearance seems to largely line up with the consensus of the Nameless One, as many accounts seem to confuse her with Her. There are exceptions, though. Predominantly, she is quite small. Reports are inconsistent, though her height has most commonly been compared to a Hootie. Details beyond this are uncertain, as most who claim to witness her fall into a panic, getting out only vague details.
Hoomans who attempt to make sketches of the Meem consistently wind up only drawing two scribbles, each vaguely in the shape of ovals. These are recognized to be interpretations of the Meem's eyes, though what that means about them is uncertain. Those who look at the drawings in the presence of the body of the Hooman who drew them often report a feeling of being watched as well as an urge to destroy the image.
In addition to The Meem's perceived role among the Hooman populace as an escort to the dying, she is also considered to be a harbinger of doom. This reputation came from the account of the sole Hooman survivor of the Hindenwawa Tragedy, as he claimed to see a figure matching the Meem's profile shortly before things took a turn for the terrible. He also claimed he could see her inaudibly talking or singing as he feebly crawled from the wreckage. The surviving Hooman went missing shortly after giving this account and was never seen again.
The nature of the Meem's connection to the Nameless One is unknown. As mentioned, the Meem makes no appearances in any of the Nameless One's theological accounts. Some seeking to connect her to the Nameless mythos argue that an infamous hymn's lyrics are from the Meem's point of view, while those who insist she is separate cite that accounts of Meem visions continued after the apothnitosis and into the current day.
"Ophania" or "Ophanymph"

If you hear what sounds like a Femhooman humming to herself in a /who/ forest, do not approach her. For your own safety, you must quickly yet quietly get away from the voice.
For the past few centuries, there have been rumors of a bewitching creature lurking in the untamed regions of /who/. Supposedly she resembles a typical Femhooman with the main distinctions being two pairs of wings, sets of talons where her hands and feet would otherwise be, and a human head resembling the consensus depiction of the Nameless One. This figure is said to only appear in the proximity of solitary Hoomans and has never been reported to be seen by any Femhooman in any circumstance.
Those who have claimed to witness her have attested that she is a terrifying yet alluring figure. Some doubt the veracity of claims of the creature's existence, arguing that "she" is just a folk figure made up to convince hunters not to go into the woods alone.
Fiend

Unlike other cryptids whose existence is contentious to varying degrees, Fiend only exists in the fearful minds of Hooties.
It's not known when or where the Fiend folk tale began, but it is an unspoken agreement among all of /who/'s adult population to maintain the facade for the sake of their kids' safety. It may or may not also be the case that Fiend "exists" to serve as a further disincentive to any would-be lawbreakers. If getting one or two limbs crushed by a giant hammer isn't enough, maybe the months of ostracization from the nation's future would help keep Hoomans from going over the edge.
Fiend is universally referred to as a giant golem with a brown bag for a head, similar to criminals who survived their punishments being required to wear brown bags over their faces. Fiend is also often mentioned to have a limp, a trait shared by anyone who endured a "don don" punishment to at least one leg. These similarities should make it clear to foreigners that Fiend is essentially a way for Hoomans to discourage their Hooties from interacting with criminals.
But if there are situations where contact is unavoidable, there has to be some way for the young Hooties to defend themselves from the horrifying monster! Fortunately, one such way exists. No matter where in /who/, Hooties are taught the same advice to avoid being attacked or abducted by Fiend: if any Hootie sees what they think is Fiend, he/she is to chant "GOLEM GET YE GONE!" while pointing at it until the nearest adult Hooman joins in on the chant. It is said that this cacaphony repels him.
Some places have "Golem hunts", where Hooties of the community (chaperoned by multiple Hoojisan, of course) search for Fiend while it's on the prowl and shoo it away when they find it. In these, it's common for somehoot to volunteer as a fake Fiend for the Hooties to repel.
Nameless Terror

Many have argued that this particular creature had never severed from the Nameless One in the first place. Its physical form is defined by pointed yet jagged teeth within an impossibly wide smile as well as an overall deathly pallor save for its pair of giant unblinking red eyes, which themselves are of black sclera. Artistic depictions of this creature vary wildly beyond this, much like how scriptural depictions alternate between speaking of it as a guardian figure to the Nameless One and suggesting it is Her when She is in a corrupted state.
Hoomaid (to be added)

Hoomaids are perhaps the /who/ cryptid whose details and even existence have the least consensus. There's no historical statement or account confirming their existence, but countless Hooman sailors and fishers swear they've seen one at some point in the past. It's not uncommon for one to go on a lengthy rambling tale that goes into a supposed encounter only for the hoot telling the tale to get sidetracked and inadvertently change the topic before getting to the point where the encounter supposedly happened. This holds true regardless of whether the account is written or recited; the story, whether gradually or suddenly, changes from a tale of a hoomaid encounter to something unrelated before said encounter takes place.
Unlike any encounters that may or may not have happened, hypothesized origins of hoomaids see no diversions or sidetracks. What they do see are boatloads of inconsistency and outlandishness. No two hypotheses are the same, and they run the gamut from "uplifted v-flukes" to "Hoomans who volunteered as sacrifices in rituals to reawaken She Who Was Here Before" to "Owliens".
Even the appearance of hoomaids is inconsistent! Is their aquatic half fish or orca? Is their terrestrial half owl, Hooman, or Nameless? Do they have lungs, gills or both? Do hoomaids have melons?
Overall, the idea of hoomaids when taken as a whole by those who believe in them is completely ludicrous. No two accounts or depictions line up. Yet believers have absolute faith in their existence. In fact, pretty much any "hoomaid truther" is willing to hear out theories spouted by hoots who hold completely different perspectives on them. Why? Because these Hoomans hold one principle above all others:
you have to consider
Taranchama

Taranchama's origin is chronicled with great clarity in /who/, though they will not be rewritten here. She is an entity of great significance to the Haatons, and though her beginning can be read in any /who/ temple, she ultimately plays a comparatively minor role in /who/'s lore to the point where it is of little hope any Hooman document would do her justice.
Unrelated Figures
Despite what one may assume, the Pink Angel is not a part of the Nameless Mythos. There are currently no known connections between it and her. Likewise with the supposed One Who Came Before. Attempts have been made to connect the former figure to the overarching mythos by claiming she was the one who created "Jerbacabra" rather than the Nameless One, as reports of its existence began after the apothnitosis.
Information about the Pink Angel (also referred to as the Pink One) and related figures has been compiled in other documents.
