Obyrith

Obyriths were an eldritch race of demons so ancient that they predated mortal life, and even the gods. They rarely had a humanoid shape, and some said that just looking at an obyrith could drive a mortal insane.

Description
Though the obyrith race teetered on the brink of extinction, enough varieties had survived the downfall of their kind to paint a dreadful picture of the sort of shapes they once took. Their abominable forms were utterly alien and bore nearly no resemblance to modern mortal life, closer as they were to basal organisms such as insects and cephalopods.

However, the obyriths were more than just revolting, for the revulsion their appearances invoked surpassed matters of mere subjective taste. More than ugly, the forms of the obyriths were simply wrong, their noxious vileness transcending to the ranks of fact. This atrociousness extended beyond visual appearance to every aspect of their existence; everything from the sounds they made, to the foul odors they exuded, to the taste they left in one's mouth was an appalling affront to all senses. Reality itself was incapable of describing the unspeakable horrors that were the objectively offensive obyriths, and even it seemingly desired to forget their vile visages.

Personality
As demons, the obyriths were cruel creatures of great malevolence. In the absence of outside threats, they had spent much of their time in power infighting, making war with each other and conducting political schemes for power. Decadence and depravity were commonplace during their time of dominion.

Abilities
Like the tanar'ri, obyriths had telepathy and were resistant to poisons, acids, fire, and cold, although the tanar'ri were fully immune to electricity where the obyriths were simply resistant. In addition to these abilities, all obyriths had truesight, could not have their minds supernaturally altered, and healed from injury with incredible speed, the exact rate dependent on the kind of obyrith.

Whereas most demon lords had access to blasphemy and unholy aura as spell-like abilities, obyrith lords had their chaotic counterparts in the form of word of chaos and cloak of chaos.

Society
Defeated and dying, relatively few obyriths remained in the Abyss's most remote recesses, and of those that did, few maintained any real influence. Those that continued to cling to existence either had the tacit approval of the tanar'ri, the effort it would take to fight them not worth their defeat, or claimed domains too inhospitable or isolated to try conquering.

Once legion, the obyrith lords had been drastically reduced in number, only a handful surviving to modern times following the destruction of their reality and the wars that followed the birth of the Abyss. However, twelve of the few remaining obyrith lords were members of a secret alliance formed to restore obyrith dominion. Since the defeat of Obox-ob, these remaining lords, called the Queen's Conclave or Quorum of the Twelve, came to the understanding that if one of them could conquer the Abyss, the obyriths would rise as a group and regain their lost power.

The members of the Conclave fought as much as any other demon lords, if only to hide their allegiance, and perhaps only members knew who the others were. Instability was advantageous, for as the new demon lords conducted their wars, new opportunities for them to seize power would emerge. The alliance was considered a myth by most, even in the Abyss, with legends stating it had fallen long ago.

Many demons weren't even aware what the title of obyrith really meant, for the tanar'ri of the past had gone out of their way to kill as many as possible in an attempt to erase them from history. Dagon was among the few, and possibly only, demon lord openly acknowledged to be an obyrith, and Pazuzu's dominion over Pazunia (where the Queen of Chaos held a once-a-millennia conference with the others) gave rise to rightful speculation he was also a participant.

Obyrith Lords

 * Areex: Titled the Forgotten Prince, no records of Areex could be found, and none could recall his nature, deeds, or why he was sealed in the Wells of Darkness. According to the synchronized barking of twenty-three gibberlings, Areex made a secret pact in "another place" with Bolothamogg, an elder evil said to be the void keeping reality from that beyond it. The message ordered him to go "Beyond the Stars" to pay the price.


 * Bechard: Known as the Rotting Husk, Bechard was an immense lord of decay and obsolescence that resembled a knotted whale. Formerly the Lord of Tempests, with perfect weather control, he had been beached on his own deviant shores by outside forces. He endured for millennia unmoving, dying painfully in the Death Dells under the hot sun as he involuntarily injured himself with ferocious wind and acid rain.


 * Cabiri: Called The Watching Master and the Many-Eyed Tyrant, Cabiri was a demon lord of observation that desired to see everything, whether fascinating or frightening. He used his divination powers to predict the future and scry into deeper layers of the Abyss, his recordings seemingly inspiring the cataloging efforts of the Fraternity of Order. He was imprisoned in the Wells of Darkness for debated reasons.


 * Dagon: Prince of the Darkened Depths, Dagon was a primeval leviathan of a demon lord whose presence brought a fear of the sea and all that lurked beneath the water. He was a maddeningly massive being, ancient and powerful even by obyrith standards, and yet also an isolationist that acted as an oracle for the tanar'ri from within the depths of the Shadowsea.


 * Dwiergus: Referred to as the Chrysalis Prince, Dwiergus was a house-sized soup of everchanging limbs that ruled The Fleshforges, an undulating, protoplasmic realm of hate and hunger. The eldritch, primordial demon lord was driven primarily by the desire to reshape all living things into demonic lifeforms, and implanted the overwhelming urge to remove a body part out of the irrational belief the Prince had tainted it.


 * The Malgoth: Once a demon lord of god-like power, the being known as the Malgoth was destroyed when seven jealous demon lords allied to assault its several haunted layers deep in the Abyss. Little more than an alien intelligence for eons, it managed to escape to the Material Plane city of Istivin, existing as a shadowy, formless abstract of gloom, menace, hate, and tragedy that infused the settlement itself.


 * Obox-ob: The original Prince of Demons, Obox-ob was said to be the first obyrith to rise from the primordial matter of the Abyss, an entropic demon lord of putrescence that could inject others with raw chaos stuff that consumed their bodies and souls. After being deposed and forced to retreat to the deep Abyssal realm of Zionyn, he was reduced to a patron of poison and spreader of entomophobia as the Prince of Vermin.


 * Pale Night: The so-called Mother of Demons that came to be known by the name Pale Night was an unknowable being of such awful shape that reality itself tried to hide her. To see the truth beyond the veil was to court death, her incorporeal form a harbinger of insanity and dreadful births. Seen as a mother figure by many in the Abyss, there was no knowing what horrors she was truly responsible for spawning.


 * Pazuzu: Prince of the Lower Aerial Kingdoms, Pazuzu declared all Abyssal skies as his, and few cared enough to fight him over such a claim. Though once an obyrith lord, he had somehow "evolved" into a kind of intermediate form between obyrith and tanar'ri, gaining a bond to evil creatures of the air in place of his once-maddening form. Upon the calling of his name thrice, he appeared to offer corruption disguised as aid.


 * The Queen of Chaos: Her actual name stricken from history, the self-styled Queen of Chaos led the obyriths to war against the rest of reality, specifically against the forces of law. Certainly a force of change, the Queen was behind the fall of Obox-Ob, and had killed, imprisoned, and weakened those obyriths that opposed her. She retreated to The Steaming Fen after her defeat and despite the hopes of a few obyriths, hadn't been seen since.


 * Sertrous: Called the Prince of Heretics, Sertrous was a minor lord of parasites and crawling things before the Queen of Chaos nearly killed him for insolence. He managed to possess a snake, and after recovering, waged war against god-devoted mortals. Though slain, his spirit bound to his severed head, the ophidiophobia-spreading fiend managed to speak words that his solar killer spread, a truth no god wanted spoken.


 * Ubothar: Known as the Thunder Below, Ubothar was a festering obyrith lord banished by the Queen of Chaos and imprisoned on the Material Plane. Worshiped by some as a destructive aspect of nature, Ubothar had spent eons slumbering deep underground. His titanic form could cause earthquakes even as he slept, and his cataclysmic awakening alone could destroy mountains.


 * Ugudenk: Referred to as the Squirming King, Ugudenk was a worm-like obyrith that primarily dug through his Writhing Realm. Seemingly immortal, it was speculated he was himself an Abyssal layer, his maw a feeding tendril that sometimes reached across the multiverse to devour at apparent random. His presence brought a fear of that which burrowed, and the crippling thought he could burst from the ground at any time.


 * Veshvoriak: Once the ruler of his own Abyssal layer, Veshvoriak had long been cast into the Iron Wastes and frozen in a glacial rift. Despite telepathically sending out ancient memories, secrets, and whispers about its wish for freedom, it wasn't clear if Veshvoriak was actually alive but frozen, slumbering, or if the long-dead obyrith's alien mind was simply emitting echoes of his last thoughts.


 * Vroth-Khun: Lurking in one of the deeper layers of the Abyss, Vroth-Khun was a gibbering, poisonous entity that had built towers from the slain bodies of his spawnlings, only to devour them and repeat the process. Like many, the Queen of Chaos banished him from the Abyss for refusing her call to war.

Other obyrith lords were known to have existed, including:


 * Asima: Titled The Unanticipated, Asima was a faceless demon lord of unfortunate surprises thought to have played a role in the creation of the Grand Abyss. Said to have betrayed the obyriths in ages past, her unrotting remains rested undisturbed for millennia, and legends said that deep in her burial mound was the identity of the members of a secret obyrith alliance.


 * Kizarvidexus: Called the Horned Duke, Kizarvidexus was described as a cloaked figure with two long, curved horns tipped in the deepest shades of red. He joined the fight against the Wind Dukes of Aaqa, managing to destroy the Wind Duke Zosiel with a sphere of annihilation before being slain by Wind Duke Icosiel. Small bits of his flesh oozed from his Well, before being scattered by a perpetual tornado and eaten by scavengers.

Ecology
In its original incarnation, the Abyss was, if anything, more horrifying than it would later become. In this harsh, primeval state of utter chaos, rampant evil, and seeming infinity, only the obyriths possessed the cunning and natural defenses needed  to survive. Life fecund and foul infested its oceans and unimaginable horror rose from the primal chaos in times long forgotten. If the tanar'ri were embodiments of Abyssal evil, then obyriths were manifestations of its chaos, and indeed the chaos of the Abyss suffused the ancient obyriths moreso than the demons spawned from mortal souls. The Demonomicon of Iggwilv went as far as to suggest that good and evil were artificial constructions that came to be when the gods gave free will to mortal beings.

Though a few tenacious breeds of obyrith managed to persist in certain layers, it was possible that the conditions for their creation had been lost with their dominion. Were an obyrith to retake the mantle of Prince of Demons however, perhaps the tanar'ri would be forced into hiding and the obyriths would resurge. Some obyriths (such as Pazuzu) had managed to progress past their roots to become their own kinds of demons, sometimes even taking humanoid form, although this was likely either due to coincidence or a cruel form of mockery.

Varieties

 * Draudnu: Draudnus were perhaps the joint creations of Obox-ob and Pale Night, bloodthirsty demons that sought to rid the Abyss of all non-obyrith life. They were referred to as the Mother of Demon's children, and their presence caused others to get the sickening sense that something was growing inside of them.


 * Ekolid: Ekolids were demons that, while intelligent, were constantly driven to reproduce by injecting non-ekolids with their eggs before the maggots viscerally burst from their bodies. They embodied the instinctual fear of becoming infested, and caused parasitosis in those nearby.


 * Golothoma: Golothomas were predatory demons compelled to devour others through the writhing darkness that was their shadows. Originating from Ugudenk's lightless tunnels, those exposed to them became obsessed with shadows, unable to stand the light and too willing to accept the dark.


 * Laghathti: Laghathti were demonic inhabitants of the River Styx that fed on the memories of those they encountered, particularly tragic ones. Their presence induced partial amnesia, much like the Styx itself.


 * Sibriex: Sibriexes were created by an ancient obyrith clan specializing in slavery and body modification. Viewing others only as material for the art that was their flesh-grafting, they were egotists whose presence drained self-worth and warped minds into believing their forms to be physical perfection.


 * Uzollru: Uzollrus were leviathans among obyriths that sought out living creatures to gleefully liquefy and drink them. Perhaps once an intelligent, civilized race, they had mysteriously been reduced to primitive, roaming monsters, their presence able to render minds feeble from their sheer size.


 * Verakia: Verakias were saurian savages, bestial obyriths to whom even Demogorgon would recognize for their ferocity. The wild fury and killing potential embodied by their claws and fangs inspired a psychopathic need to slash and slaughter in those that looked upon their feral forms.


 * Wastrilith: Wastriliths were once obyriths, but evolved into their own demonic subspecies. Reviled as water lords, with power over the oceans and their inhabitants, their corruption manifested not in a maddening form, but in how their befouling presence tainted the waters they inhabited.

History, Rumors, and Legends
Exactly how and why the first demons took form was a mystery to sages and the source of much debate. Certain texts of incalculable age claimed that both the obyriths and a race of ancient Baatorians were spawned by the fiends known as the baernaloths, ancient beings with unrivaled knowledge of lower planar creatures, though the unified creation myth had few advocates outside Gehenna and Hades. During his explorations of the Abyss, Cabiri apparently made some discovery about the creation of the obyrith race that led him to seek out the baernaloths.

Bechard, who conversed melancholically about the bygone era of the obyriths, might telepathically mention to trusted visitors that the obyriths abandoned a race of fiendish creators before migrating to the Abyss, though he only retained a small piece of his once vast mind. According to some, it was a baernaloth that Pale Night coupled with to spawn some of her Abyssal children, but similar tales replaced the baernaloth with other great beings of evil and they all seemed based more on personal bias than researched evidence. Regardless of any baernaloth involvement or lack thereof (the ancient schemers would spread both sinister secrets and dark deceptions for no other reason than to cause suffering) the oldest legends of the obyriths cast their race as being one beyond the multiverse itself.

According to legend, the obyriths had been despicable lords of evil incarnate long before mortal life forms and even the deities they worshiped had come to exist, but not in the reality they eventually found themselves in. Long ago, obyriths were the masters of a forgotten realm past the cosmos, the name of their ancient domain having been lost to time, but while technically the rulers of this reality, the obyriths were prisoners of their own actions. The vile fiends had destroyed their universe, draining the dimension of life and power to feed their dark hunger and turning whatever it once was into a decaying world of crumbling ruins.

Escape to the Abyss
The obyriths were not unaware of their limited amount of time, and one of them, purportedly Pazuzu, had hatched an idea on how they could preserve themselves. The obyriths would create a shard of ultimate evil, an object powerful enough to breach the barriers between reality. After pushing past the confines of the cosmos, the shard would serve as an entryway, a seed of evil that they could use to corrupt the most powerful entities in this realm before coming through themselves while leaving their on dying world behind. Once they bent their pawns to their will, they could finally reshape this new reality in their own unimaginable image.

Some claimed that the shard was actually comprised of many of the original obyriths, their wastes souls conglomerated in order to enact the plan. Eons passed as the waiting obyriths slowly died out, until a power-hungry entity known as Tharizdun discovered their trap and seized the shard. The obyrith conduit quickly ruined the mentally and spiritually open being, the link between them driving him insane in an instant. The obyriths demanded he place the shard in the Astral Plane, promising him total reign over it if they served him faithfully.

Unexpectedly however, Tharizdun saw an issue with this plan even in his maddened state; the gods would quickly take issue with this and turn on him before he could fully obtain the power he was promised. Rather than that, Tharizdun fled to the far corners of the cosmos and planted the seed into a churning expanse of primal chaos, a realm of fallen primordials he hoped to make his own. Power like that realm had never witnessed before erupted from the chaos where Tharizdun plunged the shard, as the nascent evil of their home exploded as black flame through a yawning vortex.
