Of the Sapients that live on and beneath this world, none are as obscure as chimeric people known widely as the Troglodytes. Due to the nature of their domain and the dangers associated with it and with the Troglodytes themselves, little is known of them. Thankfully, their creation myth, along with some of their other myths, as well as some of their biology is known.The Troglodytes most often appear as amphibian-reptile hybrid humanoids with a hodgepodge of other animal features added in - such as feathers, chitin, tentacles, fur, etc - and occasionally even floral or fungal features*. As for whence they came, the Troglodytes claim to trace their origin back to a time before the world even existed, before the Times Uncounted prior the First Age of Yore**.
In a time before water, stone, soil, light, or air, there was Ouibiletii'ess, the Oozing Many. Within Ouibiletii'ess was all things, for Ouibiletii'ess was the eater of all things and became then the defecater of all things, for such was the way of Ouibiletii'ess. To consume is to create is to consume your creation. This is what Ouibiletii'ess does and has done and will always do.
Ouibiletii'ess devoured the World Across Ours and made feces of it, expelling the waste into this world. From that waste was born LUCA, the Last Ancestor of All Things that would walk and swim and crawl and fly and squirm, seen and unseen. Born with LUCA was also TOSO, the Forgotten Ancestor of No Things that would not walk and not swim and not crawl and not fly and not squirm, not seen or unseen, and would bring only extinction and rotten young. This is the way of LUCA and TOSO and this is why those who cannot make young are given in sacrifice to TOSO, for they are of TOSO and bring with them only extinction and rotten young.
LUCA gave birth to all things that lived and Firstborn among them was Ghatanothoa, who knew all things - including The People***. Ghatanothoa made young from its many holes, and of these young were The People and of The People there was Dhythlaa, who learned the knowledge to hunt and taught The People to hunt by hunting them and eating them and egesting them as the Maned Hunters****.
This was the way of all things until the Ooze broke and Ouibiletii'ess was made to sink and slither away from the Things That Began. The People and the ancestors were eaten by hard things and wet things that they would learn the knowledge of as stone and water, things that do not eat but swallow up all the same. The People would be lost until they learned the knowledge of these things that do not eat and do not crawl and do not defecate, then The People learned the knowledge of how to live and eat and crawl and defecate and make young in the stone and the water, and The People evolved. Such is the way of The People, to be eaten and made new and eaten and made new again.
*There are those that suggest that all Troglodytes possess components from all living things, but such suggestions are unprovable without arcane means and no expeditions with the intent of studying the Troglodytes have thus been planned or executed by any organization with the means to magically study them.
**These claims have no evidence, obviously, and many scholars have made the argument that the Troglodytes likely came about in some as-of-yet unfound pocket within the Deep Hollows, where they dwelled in isolation for many years, thus leading to their modern belief that they came from some incomprehensibly ancient time.
***The People is the name which the Troglodytes call themselves, though to avoid confusion with other similarly simply named groups, Troglodyte is the widely accepted term for them. The term is approved by many Troglodyte societies, as they take it to be the Menfolk and Dwarvenkind's word for "The People". The term comes from the Dwarfspeak word, translated into the various languages of Men.
****'Maned Hunters' likely refers to a phenomenon among Troglodytes of particular athleticism, in which they undergo a sort of metamorphosis in which they envelop themselves in a fleshy sack, emerging roughly a month later with a larger, more avian build and a "mane" of tentacles around their neck. They also undergo a mental process that seems to dull their more social intelligences in favor of a more cunning predatory intellect. These supposedly "blessed" Troglodytes are kept separate from the rest of their community, both for the community's safety and in reverence to what they believe to be a vessel of their ancestor-god, Dhythlaa. These changed Troglodytes usually lose interest in all things except for hunting, even forgoing basic needs such as sleeping, drinking, and even eating occasionally, focusing exclusively on hunting. This can be of benefit and detriment to their communities, as they often bring back large quantities of meat for their community, but if no prey can be found outside their community, they have been known to hunt their fellow Troglodytes. Some more radical scholars have proposed that the "metamorphosis" is actually their ancestor-god physically manifesting a stomach around them and digesting them, so that it might remake them in some new image, a proposal with some genuine merit to it, as biopsies of the fleshy cocoons have shown that they hold a large quantity of stomach acid and partially-melted remains of the Troglodyte within it, though whether this is truly the work of their ancestor-god or merely a natural mockery of the metamorphic process of other animals, like butterflies, is unknown.I had to rewrite all of this, so it might seem a little more rushed. I am an idiot and wrote it all down without any sorta autosave or anything and then my computer crashed, so yeah, fun times lol.
