Here Roxx is with her bro and bestie Rocko, our black papillon/husky/GSD mix. Really. We got Rocko at 7 months, and then added 3-mo-old Roxanne when he was about 10 months. She is now about 10 months and is still growing. Rocko is small Alaska husky sized. They alternate between pro wrestling and jostling for prime cuddle spots. We were SURE there would be something like boxer in her mix to explain the build. My partner only rescues pitt mixes and he has never seen one as leggy and wiry as her. She looks like a damn leopard when she runs.

I'm not sure if this is the appropriate venue, please correct me if this is poor reddit etiquette.
We have 2 purebred Swedish Vallhund puppies for sale - 1 male, 1 female. Registered with the CKC.
3 months old.
Located in Ontario.
Please PM me if you'd like more info.

Gotta buy these puppies when they’re on sale. Usually $4.59. Got them for $2.50 each.

Please read Part 1 here if you haven't.

This was meant to come yesterday, but then Limbus Chapter 4 Part 2 grabbed me by the balls.

IX

​
The Nihility.
An extremely passive Aeon that believes everything is worthless, everything about them is a total mystery. Those that approach its divine body, if they even find the coordinates, disappear. Simulated Universe implies that approaching, maybe even thinking about IX, induces apathy and mental breakdowns.
IX ultimately represents nothingness - the dark side of the Universe that completes its balance, providing non-existence to existence.
Aha once helped the Annihilation Gang try to assassinate it as a joke, but it unsurprisingly ended in failure after the Elation-enhanced Gang members vanished when approaching their coordinates.
IX is the roman numeral for nine. WOW. It's almost certainly meant to be read as "nine", because of the way Device IX's name is structured. I looked for the potential significance of this number but like, nine being a number within the base 10 system we love so much basically means every culture in the universe sees it as significant.

\"Those running away from the past think no one understands their despair. When they finally take a breather, they'll find their future selves staring right at them with bloodshot eyes.\"
Those who manage to share their mentality with IX sometimes earn a glance from them. When this happens, those who fall into despair have their physical bodies self-destruct and become something called a Self-Annihilator, made out of "true nothing". Interestingly, though this initially appears to be a grim fate, Self-Annihilators are somehow still alive and capable of thinking, and it seems implied they can revert to their original forms if they regain hope.
Those, however, who remain steadfast in their beliefs become Doctors of Chaos, who are convinced they can 'heal' IX and make it see value in the universe. They do so by going around the universe preaching that you can derive meaning from it and doing crazy actions in the hopes of inspiring those around them. They also have a hobby of trying to cure Self-Annihilators, and they're pretty good at it.
Device IX is the third Nihility faction, which is so mysterious its existence is straight up questionable. It's alleged to exist in the voids underneath all Reality. The only thing that can really be traced back to them is the "dark web" which allows for the trade of rare and illegal items, and probably other things as well.

Qlipoth

​
Let the fire that forged the bricks and the ones that laid the wall's foundations be known!
The Preservation, known as the Firmament Arbiter by the Xianzhou.
Their divine corpus is so huge, it has planets orbiting it.
Qlipoth, at one point, was alerted to the "catastrophe of the Finality" and to prevent it, became building a large wall known as the Subspace Crystalline Barrier which isolates worlds from one another (or at least that's the IPC's narrative). They also built the Celestial Comet Wall and the Great Attractor Base, but we don't know what those are for yet.
Qlipoth is very ancient, being a veteran from the Dusk Wars that resulted in the disappearance of all Leviathans. The IPC claims that the Dusk Wars and the Leviathan race ended as soon as Qlipoth ascended, but this doesn't appear to be the case. Furthermore, the IPC also maintains that Qlipoth is the first ever Aeon, which also doesn't appear to be the case (Oroboros says hi)
Whenever Qlipoth strikes their hammer, the Subspace Crystalline Barrier expands, and the IPC has used this as a way of marking time in "Amber Eras", one for each hammer strike. However, the hammer strikes are inconsistent, so how long each AE lasts is different. That makes AEs a terrible way of keeping track of time, but everyone just accepts it anyway because the IPC is obsessed and arguing with the IPC is a really easy way to get on their bad side, which no one wants. On the side, most civilizations use their own timekeeping systems which are generally more accurate.
In any case, it's currently 2158 AE, with 0 AE going all the way back to the "end" of the Dusk Wars, and 0-180 AE being a 'dark spot' with few historical records. The IPC's official stance is that there just isn't much information, but it seems more likely that they're withholding records from that time period, which would indicate something about it makes them or Qlipoth look bad.
The Qliphoth is basically the "evil version" of the Kabbalistic Sefirot, the emanations through which the spirit of God reveals itself. That probably doesn't matter though, because most likely they chose it for the fact that the hebrew name קְלִיפּוֹת literally means 'shell'.

\"Seriously, out of everyone who had faced an Aeon, that old man was the calmest I've seen. Even Screwllum's gears squeaked when he saw Nous...\"
When mortals first became aware of Qlipoth's wall, there were two reactions - the first was to imitate Qlipoth, going around the universe building stuff, and the other was to help them.
The former became the Architects, who travel the universe building stuff and helping protect other civilizations. They were the ones who made Belobog's wall, core, and Engines of Creation. They must receive some implicit endorsement from Qlipoth, because they're able to tap into the Preservation's power to build their things. Generally, most people view the Architects as stubborn, but those protected by their abilities are eternally grateful and even join them.
The other...
So, a bunch of people, including geniuses Louis Fleming and Dongfang Qixing, decided to accrue a large number of construction materials to give to Qlipoth. They did this through trade, but quickly realized that in order to get what they needed, they'd have to specialize in more than just construction materials. Louis Fleming and Dongfang Qixing utilized their expertise to scam and trick establish trade deals and routes with other civilizations, until they had amassed a vast network of trade with themselves as the intermediaries.
In 1388 AE, Louis Fleming and Dongfang Qixing decided to take things one step further and founded the Interastral Peace Corporation (IPC) together, and established an universal currency (credits) that facilitated trade between species, getting rid of themselves as the middleman and also making themselves fabulously wealthy in the process. The IPC integrated themselves into the economy of various civilizations, ruining those who refused to work with the IPC or utilize credits.
As a result of this, the IPC became the most powerful entity in the universe and are very close to being its de-facto rulers - they display deference to only a handful of entities (such as the Genius Society), and even then only because they're too insular (and oftentimes protected by an Aeon) and useful to be manipulated or "coerced" into cooperating. Almost all transaction and trade in the universe is done with the oversight of the IPC and many, many civilizations rely on them for an economical backbone.
They sponsor the creation of new inventions, research that benefits them, and produce their own products while also facilitating the sales of others'. They don't merely preside over trade, they may as well own half the universe. Again, if you cut ties with the IPC, you also lose access to these things. Safe to say, no matter how awful or inconvenient the IPC may get, going against them is simply not an option for all but the most privileged or stubborn few, and those arrogant enough to try anyway will learn the errors of their ways very quickly.
Because the IPC is obsessed with the Preservation, it makes it very hard for anyone to actually study Qlipoth or go against them.
Qlipoth appears to, on some level, approve of what they're doing, since an unknown Emanator of Preservation appeared in the IPC some time ago. However, they don't make use of the vast industrial quantities of construction materials piled up in the planets orbiting them that the IPC provided at all, so in a sense, what they're doing is actually pretty useless. But still, the IPC is fueled by absolute faith to their Aeon.

Yaoshi

​
The Abundance. Known by the Xianzhou Alliance hunters as the Plagues Author, and by the Xianzhou faithful as Sanctus Medicus.
If we assume that Denizens of Abundance cannot exist without Yaoshi, then they're at minimum ~6900 (nice) years old, and possibly much, much older - the earliest Denizens of Abundance we can date having encountered the Xianzhou at 1200 SC.
Yaoshi's primary goal is the extension and continuous growth of life in the universe. The lightcone Cornucopia implies that Yaoshi views life as a form of order, which opposes the chaos of death and the early universe.
To achieve this, they 'bless' life in certain worlds, causing the sapient inhabitants to become Denizens of Abundance and also causing an outgrowth of powerful and equally long lived plant and animal life alike. Those blessings generally come in the form of great, immortal trees, whose fruit can grant long life. In general, Yaoshi prioritizes worlds and individuals who are experiencing great suffering and hardship.
Yaoshi is the mortal enemy of Lan, although it's hard to say if the feelings are mutual. Yaoshi will never rest until all beings in the universe know the blessing of life, and Lan will never rest until Yaoshi has been killed in the final and greatest hunt. Yet, the cycle goes on for eternity.
Yaoshi is a reference to the Chinese name of a Buddha called Bhaiṣajyaguru, which is a Buddha most commonly associated with healing and medicine, and is also pretty important, being up there with Shakyamuni (aka THE Buddha). He's a doctor who vowed to rid the world of pain and suffering. So yeah, makes sense.

Followers

​
\"The mercy of Sanctus Medicus, the Ambrosial Arbor's new growth. Disciples shall attain enlightenment together.\"
Those blessed by Yaoshi gain remarkable biology - their cells and biological systems are placed in a state of perfect equilibrium, made possible through the ability for their cells to freely convert between differentiated cells and stem cells (builder cells, which can turn into any other kind of cell). This gives them the ability to effectively, live forever, as well as an extremely powerful healing factor. Though it does not altogether prevent death, it does allow for things such the regrowth of lost limbs and organs. The unfortunate fact of this arrangement is that the body when it is born provides a 'blueprint' for the blessing, making those born with congenital defects forever unable to correct them with surgery - the body will simply "heal" the "damage".
However, there is another aspect to Yaoshi's blessing - upon fulfilling certain conditions, blessed individuals have a marked shift in biology, causing a form of 'evolution' that fundamentally alters their biology. This can fix things such as congenital defects but also essentially puts cells into overdrive, exacerbating existing biological processes of the species (such as molting for reptilian beings) and potentially causing insanity. For the Xianzhou natives, this is known as being 'stricken with mara'.
Those who manage to survive the process with intelligence become known as the Denizens of Abundance who go around singing praises of Yaoshi. However, Yaoshi's blessing also causes fundamental deficits that force those long-life species into either constant suffering or constant conquest in other to offset these setbacks (such as the borisin's implied necessity to take over other worlds to house the hives necessary to create their biotechnology). The Denizens of Abundance love Yaoshi for making their lives "better", and are thus the sworn enemies of the Xianzhou Alliance, which also hates them and are seen (naturally) as blasphemers.
Of course, there are also many civilizations that greatly regret contact with Yaoshi, such as of course, the Xianzhou Alliance.
People who know of Yaoshi but are mortal and long for their blessing are known as Elixir Seekers, immortality hunters who go around the universe hoping to meet and be blessed by Yaoshi. Probably the most well-known Elixir Seekers were, indeed, the original Xianzhou fleet, which was sent out by an unnamed emperor into the stars in order to obtain immortality. Funnily, even though they did get it, they never returned to their homeworld. I wonder what it was like?
The Disciples of Sanctus Medicus were the internal faction in the Xianzhou that worshipped Yaoshi and actively held contact with them, being led by an Emanator of Abundance named Shuhu. Yaoshi did speak to their disciples as well as other Denizens of Abundance and may have even spoken to the actively hostile Alliance as well, but the specifics of this are mired in legend and mystery, and so Yaoshi's true intentions regarding their followers are unclear.

Oroboros

​
The Mariners' Intemperance
The Voracity.
Wants to eat everything (eats planets), and was a Leviathan, which makes them about as old if not older than Qlipoth. Potentially, they are the only surviving Leviathan.
That's about it. We don't know anything else.
The Ouroboros is a well-known Western symbol with philosophical and alchemical significance that consists of a dragon or snake eating its own tail. Mostly it represents infinity. It was probably chosen though because Oroboros is the dedicated vore god. Cool!

Aha

​
Look upon the courtesans' extravagance.
The Elation, known as Joyseeker to the Xianzhou.
Hard to tell if it's true, but legend goes that Aha once actually reached the end of the Imaginary Tree. When they did so, they appeared to have gained some sort of advanced perception, and began to view the universe as one huge joke. Perhaps they realized they were made by a video game company? They certainly seem to have some sort of heightened awareness.
In any case, though Aha claims and seems to believe that they only wish for others to see the humor in all things, their true purpose as an Aeon is that they serve as a catalyst of change, manipulating reality in extremely minor and undetectable ways until they butterfly effect massive events into happening. Although the displays of their power are minor compared to Qlipoth's massive wall or Lan's planet purging arrows, their effects on the universe far outweigh the others.
They owe this success due to their closeness to mortals - unlike most Aeons who barely even bother communicating with others and are by nature mysterious, Aha displays a strong understanding of human society, as a matter of fact, they believe it is the exclusive privilege of intelligent beings to understand joy. This understanding allows them to mess around with people on a far more personal level than other Aeons do, even getting involved with other, separate factions if they believe it's funny enough. They're also especially talkative.
Of course, sometimes they decide to be major instead, and do a little bit of trolling. Trolling attempts include blowing up half the Express and an entire planet after hiding out on it for a year disguised as a human (success), helping the Annihilator Gang assassinate IX (failure), trying to get a Noblesse Worm into the Genius Society (failure). And although the latter two appear like failures to us, I'm sure they got great enjoyment out of the bewildered reactions of those observing them.
Aha is laughter, obviously, but it could also be a reference to various things including the 1980s Norwegian band, which composed Take on Me. That sounds stupid but that's Aha for you.

Followers

​
Well, bye for now. Send my regards to the guys and girls in the tavern.
Aha attracted a group of straightforward followers called the Masked Fools that go around the Universe doing a little bit of trolling, though more specifically they act as agents of change that have been responsible for starting riots and revolutions (including a notable one against Rubert I during the Emperor's War), and they're not above violence. They also maintain taverns and other places centered around having fun and doing trolling.
Simultaneously, however, they also have a group of *anti-*followers called the Mourning Actors, who instead go around the universe being sad, noting the destruction of worlds and death, encouraging celibacy and abstinence, among other things, in the hopes of opposing the Elation. Aha thinks this is hilarious, and also recognizes tragedy as the flipside of comedy, so they purposefully enhanced them, allowing them to travel the stars.
Although the Mourning Actors are mostly ignored by the universe, they possess an uncanny ability for detecting tragedy (probably Aha's fault); they visited Jarilo-VI when it was embroiled in the war against the Antimatter Legion, and they have some use as announcers for when worlds are destroyed or civilizations fall, often being the first to broadcast these events to the universe.
Aha makes basically anything and anyone into an Emanator so long as they think it's funny, so it's not really worth noting here. That said, the one Emanator we do know of was a Noblesse Worm that they infused with super-intelligence to see if Nous would accept them into the Genius Society (they would not)

Fuli

​
And finally, measure the world against yourself, and take all such things to heart.
The Remembrance.
Fuli's age's unknown, with records of them being essentially non-existent. Their ultimate goal is to preserve all of the universe's memories in order to facilitate "the rebirth of the universe", and they have the memories of every single living being in the universe, including those of other Aeons.
They physically manifest before the occurrence of extremely significant events in the universe's history, and then vanish after obtaining whatever it was they needed from it. When this happens, they appear as a being made out of a mirror-like crystal. Though this has happened many times, their only recorded manifestation was at the end of a speech by the aging Louis Fleming, in his final public appearance.
Fuli is named after a deity in the Shenxiao sect of Taoism. English sources for this are basically non-existent - I put the Chinese wikipedia article through DeepL and got the world's most sophisticated word salad and basically all I could gather is that he was the father of some bigshot emperor. Okay.

Memes: The DNA of the soul
Fuli utilized their power to enhance a specific group of mortals, allowing them to abandon their physical forms and live on as memetic lifeforms (not internet memes, ideas and behaviors that spread from person to person within a society, though HSR basically uses the term as "things that live in your brain"). This allows them to interact with a being's memories and subjective perception directly. It also allows them to freely travel between worlds without any physical effort on their part, which sure is neat!
This faction became known as the Garden of Recollection, with the most active members being the Memokeepers, who preserve the memories of individuals considered significant. They also created Light Cone technology, which allows them to physically manifest and preserve the memory of an individual. Most Memokeepers prefer to keep themselves hidden, disguising themselves and harvesting the memories of others without ever being acknowledged. If a being possesses exceptional memories or qualities such as the Trailblazer, they might choose to manifest and communicate with them directly.
Because the Garden of Recollection members are memetic lifeforms, they can only manifest to people who know about Fuli, the Remembrance, or associated concepts. If you literally don't know anything, you're inaccessible to them. After all, these spicy memes have not been passed on to you.
The Garden of Recollection doesn't have just Memokeepers. It seems some members (or defectors?) known as Memosnatchers go around forcefully taking the memories of other individuals, potentially causing amnesia. Because the Messenger calls them "those thieves", it seems they're not looked highly upon by Fuli's other followers.
Another faction in the Garden of Recollection that draws the ire of the Memokeepers are the Cremators, extremists who steal memories gathered by others and destroy the ones they consider to be useless and return the important ones. In doing so, they believe themselves to act as a sort of filter or curator for the memories of the Aeon, relieving them of their "burden". The stance of the Garden of Recollection is that every memory has value, so obviously the Cremators aren't seen in a positive light.
In any case, the current objective of the Garden of Recollection is preserving the universe against the Destruction, believing that everyone can still live on through memories. Ultimately though, the Garden of Recollection likely existed long before Nanook's ascension, and their greatest goal is to fill Fuli's pure land with memories, which assists Fuli's own ultimate goal... which is unclear to us at the moment.

Idrila

​
Listen to the infant in the mirror.
The Beauty, known to the Xianzhou as the Wondergazer, and also in some places as Anne Duray.
Though mortals superficially interpret them as a god of beauty, Idrila's true nature revolves around the realm of perception - your conscious qualia (sight, smell, taste, etc), your ability to reason, and the values instilled upon you by your own personal circumstances. The intersection of these attributes is what creates the subjective idea of 'beauty'. In other words, beauty exists in the eye of the beholder.
Idrila cannot create beauty. Instead, they can manipulate these attributes to embody something that's always going to be beautiful to the observer, independently of their tastes. A memory bubble even implies that Idrila is even capable of granting sapience to unintelligent species, creating the conditions for them to be able to observe 'beauty'. Idrila, essentially, allows beings to "observe" the universe in its purest form.
This causes the people exposed to Idrila's power to frequently become intensely obsessed to the point of insanity, and many legends describe those affected by them as committing devastating acts for Idrila's sake - something which gave them a large amount of pleasure. They created civilizations and tore apart people who were in love just by existing.
It's probably safe to say that no one knows what Idrila really looked like, but it was always the most beautiful thing they've seen.
One day, Idrila just up and disappeared. Adios. The Mirror Holders believe that Idrila 'died' and shattered into many pieces, and could return if those pieces are gathered again. The Knights of Beauty believe that Idrila is still very much alive, just... hiding out somewhere, I guess.
I tried to figure out what the name "Idrila" might be derived from, but I couldn't find anything. The Japanese and Chinese characters are phonetic. Anne comes from Anna which comes from the hebrew Hannah which means grace or favor, as in "God graced me with a child". Duray is a significant royal family in France and Scotland which derives from an old French word that means king. So like, King/Queen of Grace I guess. Cool.

\"If I win, please admit that Idrila the Beauty is the most beautiful of all!\" - Argenti
Among Idrila's followers (of which is implied that there are many of), the most tame are the Knights of Beauty, which run around the universe telling everyone how awesome their Aeon is (kind of a trend). They practice a chivalric code which basically says that you can only be worthy of the Aeon GF if you grind hard everyday to become the greatest gigachad of them all. Because of this, other factions in the universe regard them as not having a whole lot of faith in their Aeon. I mean, if you make your entire dynamic a competition to see which of you is the most deserving of getting your god's attention, you're basically saying that your god would never care about most people, right? Only the best ones. Then again, maybe Idrila really is like that.
Idrila, did, however, have more faithful followers, the Mirror Holders, who possess artifacts named Mirrors of Transcendence. These artifacts hold within them some level of Idrila's power, which allows the wielder to project an observer's subjective perception of the most ideal beauty outwards into reality. Usually, the Mirror Holders seem to use this to indoctrinate new people into their thirst cult. A Mirror Bubble implies that the Mirror Holders may also be Emanators, but maybe it's just one person who happens to be both an Emanator of Beauty and a Mirror Holder.
Though the Knights of Beauty hold the delusion that their Aeon GF will someday come back, and I guess decide which one among them is the most fabulous, the Mirror Holders have a different perspective. They believe Idrila 'died' because of society developing differing subjective views on beauty, shattering them into pieces. As a result, they work to make sure society has an unified view of aesthetics, while also hunting down the remainder of Idrila's artifacts. They believe these combined factors will allow their god to return, ushering in an age of harmony where everyone is really infatuated with Idrila all the time. I guess that sounds like heaven to them.

Tayzzyronth

​
Tayzzyronth... Tayzzy█ronth... Ta█yzzy█ronth... Ta█yzz██y█ronth█... Ta█... █yzzy███ron█th███...
The Propagation. Known as the Swarm Author by the Xianzhou and the Imperator Insectorum in some places.
Tayzzyronth was a very, very lonely beetle who, after getting fed up with being all alone, appears to have developed the ability to self-duplicate endlessly, ascending into short-lived Aeonhood afterwards. What resulted was one of the most severe catastrophes to affect the universe, the Swarm Disaster.
Worlds were invaded and turned into massive hives that to this day are uninhabitable despite the loss of their master. Tayzzyronth's clones slaughtered all living beings in their path, bred endlessly, and moved on to the next world, all in blistering speeds. The scale of destruction was so massive that it actually worried the IPC for maybe the first time since the Emperor's War.
Tayzzyronth seemed close to unstoppable and posed a very real risk of destroying the entire universe, when the sheer intensity of their threat caused an incredibly rare occurrence in the universe - multiple Aeons put their personal missions and differences aside and teamed up to get rid of Tayzzyronth once and for all.
We don't know the specifics of Tayzzyronth's death, but it involved them being encased in an organic prison, which appears to have deprived the rest of the Swarm of the ability to reproduce. After this, something killed them, which put an end to the Swarm Disaster for good.
However, just because Tayzzyronth's dead doesn't mean the Swarm disappeared completely, or that they may never return. The surviving members of the Swarm managed to evolve into different beings, the worlds converted into hives by the Swarm are still to this day impossible to live in, and fragments of the Imperator Insectorum's prison and body still buzz with activity and an energy that makes it very possible they might still return.
Even though Tayzzyronth lived for only a tiny amount of time compared to most Aeons, their destructive impact on the universe cannot be understated. After all, it might even be possible that they indirectly led to Nanook's ascension, due to the Swarm's attempted takeover of Adlivun.
Tayzzyronth didn't seem to have followers, much less Emanators - it seems their own clones were all they ever needed.
I actually feel kinda bad for them. Beetle just wanted a friend.
Can You Believe It, just like Idrila this is another name with no real source. Personally, I think it might just be completely made up, perhaps made to sound like something a bug would make.

Mythus

​
The Waves as they Enter the Dream
The Enigmata.
Like Qlipoth and Fuli, Mythus too believes that there is some sort of calamity approaching the universe. Their approach to it, however, is a bit different - the Enigmata sees the obfuscation of the past and of observable facts to create a 'mist of uncertainty' that obscures a 'narrative drive' determining the Universe's fate, which would allow everyone to escape that calamity.
Of course, since the Erudition directly wants to observe the Universe and solve it, that would only ensure the opposite, which makes them Mythus' direct enemy.
From latin Mythus. Means myth. Comes from Greek μῦθος (muthos), means tale, myth, legend. It's not that deep.

Followers

To achieve their goal, Mythus appears to random mortals already teetering on the edge of obscurity and 'inspires' them into becoming even crazier than they likely already were. The Riddlers specialize in obfuscating language, whereas Mythus' own personal Emanators, the History Fictionologists, mess with historical records and memories, making certain historical events more confusing, harder to understand, or just straight up inaccessible.
The items created by Mythus' followers possess the supernatural ability to directly affect history, even though history is more or less an abstract concept and those are physical items. As such, it can be assumed that Mythus is granting them their power in this way, which makes them one of the more proactive Aeons.

HooH

​
The Tipping of the Balance
The Equilibrum.
They merged their consciousness with the logic of the universe itself, hoping to attain perfect universal equilibrium. While many attempt to outsmart HooH and make things unbalanced in their favor, HooH has already accounted for them, and victory is impossible. Even if something is unbalanced now, it'll become balanced eventually, and HooH's patience is unmatched by any other Aeon.
HooH's English name is made up and meant to appear symmetrical, as is the case for HooH's original Chinese name, which is 互. This character means "mutually" or "reciprocally" or "intertwining". It was probably chosen just because it looks symmetrical from the top down, but that last meaning does have the added bonus of fitting with the fact HooH is woven into the fabric of the universe.

Followers

​
Long Arm
Those who like the cut of HooH's gib become dedicated to balancing the universe, the Arbitrators, who decided they'd try and get rid of extreme binary concepts, placing everything in balance. But because they're mortal, they don't have the great big picture view HooH has, and so they constantly mess up, having to correct their problems in successive "patches".
An Arbitrator talks to you when you reach the first Trial of the Equilibrium, and it seems they possess the ability to alter the entire universe in a scale that's incomparable to the followers of other Aeons. It may be because HooH has somehow managed to integrate themselves into the universe much further than any other Aeon has, and that might explain why Aeons tend to be opposed by those with equalizing concepts, and out of control Aeons tend to get the shaft.
Think about it. Tayzzyronth was a threat, but several Aeons believe Nanook is already going to destroy the universe. Why don't they team up again and kick their ass if so? Well, because they're balanced about it. Nanook's rate of destruction is slow and easy to counter enough that unlike Tayzzyronth, they can't take over the entire universe in years. Therefore, in a sense, they already have a place in equilibrium. For every planet-destroying campaign that takes centuries, Yaoshi and the Architects have already protected 5 other worlds. There's no need for something, or someone, to push them towards correcting that balance.

Ena

​
I only survived because the spirit of \"fuck it we ball\" burned brighter than the \"it's so over\" around me.
The Order.
An Aeon that was absorbed by Xipe due to conceptual overlap when the latter ascended, which is safe to say, a pretty definitive death (though perhaps some part of Ena lives on through Xipe? I mean, they are a plural Aeon after all)
Ena's only known group of followers are the Beyond the Sky Choir, a choir group that made songs praising the Order. When Ena was absorbed, they effectively disappeared, no longer having a god to worship.
However, the Choir audience did record some of their performances into special disks, that could only be played with unique Phonographs of Order. The problem is, the last Phonograph was lost during Emperor Rubert 1's campaigns, so nobody can ever listen to them again.
As a result, this Path is deader than dead. Maybe the energy's still accessible, but with no Aeon, no followers, and no extant artifacts, it might as well not exist.
Ena is a character from the web animation series ENA made by Peruvian artist and animator Joel- wait no.
Actually, I don't know where the English translators got the name "Ena" from, but their original name is 太一 or Taiyi, which is the supreme deity of Heaven worshipped during the Chinese Han Dynasty. There's a lot to Taiyi, but I'm just going to ignore all of it because it was probably actually chosen because the name literally means "Great Oneness" or "Great Unity".

Long

​
I didn't know what to put here.
The Permanence.
A Chinese dragon thing, Long died ages ago, but we don't know how. Before they died though, they left descendants in the form of Long's Scions, or the Vidyadhara, which possess the power of the Permanence in their very biology.
Because of this, the Vidyadhara have a very peculiar characteristic - when they reach the natural end of their lifespans, they pull a Turritopsis dohrnii and regress back into an infantile stage, effectively making them ageless. Of course, the Vidyadhara that 'reincarnates' loses all memories of their previous self, making the newly reborn Vidyadhara a different individual altogether, though Vidyadhara culture does encourage seeking a greater connection to your past incarnation. It's also possible they might be able to experience some aspects of their previous lives through dreams.
Vidyadhara, however, cannot reproduce. This means that their numbers are limited and losses to their population (through unnatural means) are permanent. Frankly as far as I'm concerned, this basically means Vidyadhara extinction is inevitable, as statistically speaking they probably wouldn't be able to avoid dying through accidents or intentional acts forever.
Currently the vast majority of Vidyadhara live among the Xianzhou Alliance, and it's rumored that those among them that fulfill certain conditions and pass specific rites can return to the form of a dragon. The High Elder of the Vidyadhara receives strict training in order to one day become the highest among them, the Imbibitor Lunae.
Another thing about Vidyadhara. The fact the Permanence's power flows through their cells allows individuals who have harvested Vidyadhara bone marrow to transplant some of that power into their own bodies, provided that they have the right ingredients to reactivate the stem cells. For regular mortals this only results in a short lived burst of power before their immune system destroys the transplanted Vidyadhara cells, resulting in a catastrophic regression that would most likely lead to death for most individuals.
However, for long-life species blessed by Yaoshi, Long's power can actually stabilize the explosive evolutionary process... allowing those stricken with mara to retain their sanity.
The cost is only a little murder.
Long is the Chinese name for the dragon (or specifically the Chinese dragon which is different from the Western perception). WOW! However, dragons do have great significance in Chinese folklore and culture and were worshipped, so this is a fine name. They also have associations with water, which is probably why the Vidyadhara are also associated with water.

Terminus

The Shapeless Prince
The Finality.
If we ignore bits of CBT2 that were removed upon release and now exist in a canonical limbo, this Aeon is the one we basically know the least about. I mean sure they've been mentioned more than Oroboros has, but we at least know what Oroboros is, and what their objectives are.
Terminus, though? Well, besides the fact that the IPC (and maybe Qlipoth) oppose their goals... we know the name "Terminus" and the Path of "the Finality", and that's it. They encountered Akivili at some point, so they're active somewhere, but that doesn't tell us much.
Terminus does appear to share a bit of a concept with an important HI3 character, the Herrscher of Finality, but there doesn't seem to be any direct connection, and finding actual summaries and information on stuff that happens toward the latter half of HI3's story that aren't too short or badly written to be useful is impossible. I'd have to play the game and read all the side-content, and frankly that'd take me weeks, and this post already took a long time to write as it is.
So we'll take Terminus for what the game tells us about them, which is nothing.
Terminus is the Roman name of a god that presided over boundary stones (his name also refers to those stones), which were meant to mark, you know, boundaries. Like the limits of a region or an area that couldn't really be represented by natural landmarks. Essentially, he was the end of one place and the start of another. Considering that Fuli's lore hints at a cyclical nature to the universe, this is an interesting name.
In Chinese, though, their name is different. It's 末王, which literally means "king of the end". Quite the powerful name.

And that's the end of the Aeon section. Because the manuscript for the mortal characters hasn't been written, it'll take a while longer to come out. Probably a few weeks. If I end up finishing it too close to the release of the remaining Companion Quests, it'll have to wait until after.
