The chaotic power of the Abyss rewards demons of particular ruthlessness and ingenuity with a dark blessing, transforming them into unique fiends whose power can rival the gods. These demon lords rule through cunning or brute force, hoping to one day claim the prize of absolute control over all the Abyss.

Although most demon lords rise up from the vast and uncountable mobs of demons rampaging across the Abyss, the plane also rewards outsiders that conquier any of its infinite layers. The elven goddess Lolth became a demon lord after Corellon Larethian cast her into the Abyss for betraying elvenkind. Sages claim that the Dark Prince Graz’zt originated on some other plane before stealing his abyssal title from another long-forgotten demon lord.

The greatest sign of a demon lord’s power is its ability to reshape an abyssal realm. A layer of the Abyss controlled by a demon lord becomes a twisted reflection of that fiend’s vile personality, and demon lords seldom leave their realms for fear of allowing another creature to reshape and seize it.

As with other demons, a demon lord that dies on another plane has its essence return to the Abyss, where it reforms into a new body. Likewise, a demon lord that dies in the Abyss is permanently destroyed. Most demon lords keep a portion of their essence safely stored away to prevent such a fate.

Baphomet Prince of Beasts
Civilzation is weakness and savagery is strength in the credo of Baphomet, the Horned King and the Prince of Beasts. he rules over minotaurs and others with savage hearts. He is worshiped by those who want to break the confines of civility and unleash their bestial natures, for Baphomet envisions a world without restraint, where creatures live out their most savage desires.

Cults devoted to Baphomet use mazes and complex knots as their emblems, creating secret places to indulge themselves, including labyrinths of the sort their master favors. Bloodstained crowns and weapons of iron and brass decorate their profane alters.

Over time, Baphomet’s cultists become tainted by his influence, gaining bloodshot eyes and coarse, thickening hair. Small horns eventually sprout from the forehead. In time, a devoted cultist might transform entirely into a minotaur – considered the greatest gift of the Prince of Beasts

Baphomet himself appears as a great, black-furred minotaur, 20 feet tall with six iron horns. An infernal light burns in his red eyes. Although filled with bestial bloodlust, there lies within a cruel and cunning intellect devoted to subverting all of civilization.

Baphomet wields a great glaive called Heartcleaver. He sometimes casts this deadly weapon aside so that he can charge his enemies and gore them with his horns, trampling them into the earth and rending them with his teeth like a beast.

Demogorgon Prince of Demons
Prince of Demons, the Sibilant Beast, and Master of the Spiraling Depths, Demogorgon is the embodiment of chaos, madness, and destruction, seeking to corrupt all that is good and undermine order in the multiverse, to see everything dragged howling into the infinite depths of the Abyss.

The demon lord is a meld of different forms, with a saurian lower body and clawed, webbed feet, as well as suckered tentacles sprouting from the shoulders of a great apelike torso, surrounded by two hideous simian heads, named Aameul and Hathradiah, both equally mad. Their gaze brings madness and confusion to any who confront it.

Similarly, the spiraling Y sign of Demogorgon’s cult can inspire madness in those who contemplate it for too long. All the followers of the Prince of Demons go mad, sooner or later.
Fraz-Urb’luu the Prince of Deception
All demons are liars, but Fraz-Urb’luu is the Prince of Deception and Demon Lord of Illusions. He uses every trick, every ounce of demonic cunning, to manipulate his enemies – mortal and fiend alike – to do his will. Fraz-Urb’luu can create dreamlands and mind-bending fantasies able to deceive the most discerning foes.

Once imprisoned for centuries below Castle Greyhawk on the world of Oerth, Fraz-Urb’luu has slowly rebuilt his power in the Abyss. He seeks the pieces of the legendary staff of power taken from him by those who imprisoned him, and commands his servants to do likewise.

The Prince of Deception true form is like that of a great gargoyle, some 12 feet tall, with an extended, muscular neck and a smiling face framed by long, pointed ears and lank, dark hair, and bat-like wings are furled against his powerful shoulders. He can assume other forms, however, from the hideous to the beautiful. Often the demon lords becomes so immersed in playing a role that the loses himself in it for a time.

Many of the cultists of Fraz-Urb’luu aren’t even aware they serve the Prince of Deception, believing their master is a beneficent being and granter of wishes, some lost god or celestial, or even another fiend. Fraz-Urb’luu wears all these masks and more. He particularly delights in aiding demon-hunters against his demonic adversaries, driving the hunters to greater and greater atrocities in the name of their holy cause, only to eventually reveal his true nature and claim their souls as his own.
Graz’zt the Dark Prince
The appearance of the Dark Prince is a warning that not all beautiful things are good. Standing nearly nine feet tall, Graz’zt strikes the perfect figure of untamed desire, every plane and curve of his body, every glance of his burning eyes, promising a mixture of pleasure and pain. A subtle wrongness pervades his beauty, from the cruel cast of his features to the six fingers on each hand and six toes on each foot. Graz’zt can also transform himself at will, appearing in any humanoid form that pleases him, or his onlookers, all equally tempting in their own ways.

Graz’zt surrounds himself with the finest of things and the most attractive of servants, and he adorns himself in silks and leathers both striking and disturbing in their workmanship. His lair, and those of his cultists, are pleasure palaces where nothing is forbidden, save moderation or kindness.

The dark Prince of Pleasure considers restriction to be the only sin, and takes what he wants. Cults devoted to him are secret societies of indulgence, often using their debauchery to subjugate others through blackmail, addiction, and manipulation. They frequently wear alabaster masks with ecstatic expressions and ostentatious dress and body ornamentation to their secret assignations.

ALthough he prefers charm and subtle manipulation, Graz’zt is capable of terrible violence when provoked. He wields the greatsword Angdrelve, the Wave of Sorrow, its wavy, razor-edged blade dripping acid at his command.
Juiblex the Faceless Lord
Called the Faceless Lord and the Oozing Hunger in ancient grimoires, Juiblex is demon lord of slime and ooze, a noxious creature that doesn’t care about the plots and schemes of others of its kind. It exists only to consume, digesting and transforming living matter into more of itself.

A true horror, Juiblex is a mass of bubbling slime, swirling black and green, with glaring red eyes floating and shifting within it. It can rise up like a 20-foot hill, lashing out with dripping pseudopods to drag victims into its bulk. Those consumed by Juiblex are obliterated.

Only the truly insane worship Juiblex and tend to its slimes and oozes. Those who offer themselves up to the demon lord are engulfed by it and become vaguely humanoid, sentient oozes. The bodies of these former flesh-and-blood creatures form Juiblex’s extended physical body, while the demon lord slowly digests and savors their identities over time.
Lolth Demon Queen of Spiders

Orcus Demon Prince of Undeath
Orcus is the Demon Prince of Undeath, known as the Blood Lord. He takes some pleasure in the sufferings of the living, but far prefers the company and service of the undead. His desire is to see all life quenched and the multiverse transformed into a vast necropolis populated solely by undead creatures under his command.

Orcus rewards those who spread death in his name by granting them a small portion of his power. The least of these become ghouls or zombies who serve in his legions, while his favored servants are the cultists and necromancers who murder the living and then manipulate the dead, emulating their dread master.

Orcus is a bestial creature of corruption with a diseased, decaying look. He has the lower torso of a goat, and a humanoid upper body with a corpulent belly swollen with rot. Great bat wings sprout from his shoulders, and his head is like the skull of a goat, the flesh nearly rotted from it. In one hand, he wields the legendary Wand of Orcus.
Yeenoghu the Prince of Gnolls
The Beast of Butchery appears as a great battle-scarred gnoll, towering 14 feet tall. Yeenoghu is the Gnoll Lord, and his creations are made in his twisted image. When the demon lord hunted across the material plane, packs of hyenas followed in his wake. Those taht ate of great Yeenoghu’s kills became gnolls, emulating their master’s ways. Few others worship the Beast of Butchery, but those who do tend to take on a gnoll-like aspect, hunched over, and filing their teeth down to points.

Yeenoghu wants nothing more than slaughter and senseless destruction. The gnolls are his instruments, and he drives them to ever-greater atrocities in his name. Yeenoghu takes pleasure in causing fear before death, and he sows sorrow and despair through destroying beloved things. He doesn’t parlay; to meet him is to do battle with him – unless he becomes bored. The Beast of Butchery has a long rivalry with Baphomet, the Horned King, and the two demon lords and their followers attack one another on sight.

The Gnoll Lord is covered in matted fur and taut, leathery hide, his face like a grinning predator’s skull. Patchwork armor made of discarded shields and breastplates is lashed onto his body with heavy chains, decorated by the flayed skins of his foes. He wields a triple-headed flail called the Butcher, which he can summon into his hand at will, although he is as likely to tear his prey apart with his bare hands before ripping out its throat with his teeth.
Zuggtmoy the Lady of Fungi
The Demon Queen of Fungi, Lady of Rot and Decay, Zuggtmoy is an alien creature whose only desire is to infect the living with spores, transforming them into her mindless servants and, eventually, into decomposing hosts for the mushrooms, molds, and other fungi that she spawns.

Utterly inhuman, Zuggtmoy can mold her fungoid form into a approximation of a humanoid shape, including the skeletal-thin figure depicted in grimoires and ancient art, draped and veiled in mycelium and lichen. Indeed, much of her appearance and manner, and that of her servants’, is a soulless mockery of mortal life and its many facets.

Zuggtmoy’s cultists often follow her unwittingly. Most are fungi-infected to some degree, whether through inhaling her mind-controlling spores or being transformed to the point where flesh and fungus become one. Such cultists are fungal extensions of the Demon Queen’s will. Their devotion might begin with the seemingly harmless promises offered by exotic spores and mushrooms, but quickly consumes them, body and soul.

Sharing a layer of the Abyss with Juiblex, plus their mutual insatiable hunger, has made the two demon lords mortal enemies, each devoted to destroying and ultimately devouring the other.
Spawned in the Infinite Layers of the Abyss, demons are the embodiment of chaos and evil – engines of destruction barely contained in monstrous form. Possessing no compassion, empathy, or mercy, they exist only to destroy. The Abyss creates demons as extensions of itself, spontaneously forming fiends out of filth and carnage. Some are unique monstrosities, while others represent uniform strains virtually identical to each other. Other demons (such as manes) are created from mortal souls shunned or cursed by the gods, or which are otherwise trapped in the Abyss. Demons respect power and power alone. A greater demon commands shrieking mobs of lesser demons because it can destroy any lesser demon that dares to refuse its commands. A demon’s status grows with the blood it spills; the more enemies that fall before it, the greater it becomes. A demon might spawn as a manes, then become a dretch, and eventually transform into a vrock after untold time spent fighting and surviving in the Abyss. Such elevations are rare, however, for most demons are destroyed before they attain significant power. The greatest of those that do survive make up the ranks of the demon lords that threaten to tear the Abyss apart with their endless warring. By expending considerable magical power, demon lords can raise lesser demons into greater forms, though such promotions never stem from a demon’s deeds or accomplishments. Rather, a demon lord might warp a manes into a quasit when it needs an invisible spy, or turn an army of dretches into hezrous when marching against a rival demon lord. Demon lords only rarely elevate demons to the higher ranks, fearful of inadvertently creating rivals to their own power. Wherever they wander across the Abyss, demons search for portals to the other planes. They crave the chance to slip free of their native realm and spread their dark influence across the multiverse, undoing the works of the gods, tearing down civilizations, and reducing the cosmos to despair and ruin. Some of the darkest legends of the moral realm are built around the destruction wrought by demons set loose in the world. As such, even nations embroiled in bitter conflict will set their differences aside to help contain an outbreak of demons, or to seal off abyssal breaches before these fiends can break free. Demons carry the stain of abyssal corruption with them, and their mere presence changes the world for the worse. Plants wither an die in areas where abyssal breaches and demons appear. Animals shun the sites where a demon has made a kill. The site of a demonic infestation might be fouled by a stench that never abates, by areas of bitter cold or burning heat, or by permanent shadows that mark the places where these fiends lingered. Outside the Abyss, death is a minor nuisance that no demon fears. Mundane weapons can’t stop these fiends, and many demons are resistant to the energy of the most potent spells. When a lucky hero manages to drop a demon in combat, the fiend dissolves into foul ichor. It then instantly reforms in the Abyss, its mind and essence intact even as its hatred is inflamed. The only way to truly destroy a demon is to seek it in the Abyss and kill it there. A powerful demon can take steps to safeguard its life essence, using secret methods and abyssal metals to create an amulet into which part of that essence is ceded. If the demon’s abyssal form is ever destroyed, the amulet allows the fiend to reform at a time and place of its choosing. Obtaining a demonic amulet is a dangerous enterprise, and simply seeking such a device risks drawing the attention of the demon that created it. A creature possessing a demonic amulet can exact favors from the demon whose life essence the amulet holds – or inflict great pain if the fiend resists. If an amulet is destroyed, the demon that created it is trapped in the Abyss for a year and a day. Despite the dark risks involved in dealing with fiends, the mortal realm is fulled with creatures that covet demonic power. Demon lords manipulate these mortal servants into performing ever greater acts of depravity, furthering the demon lord’s ambition in exchange for magic and other boons. However, a demon regards any mortals in its service as tools to use and then discard at its whim, consigning their mortal souls to the Abyss. Few acts are as dangerous as summoning a demon, and even mages who bargain freely with devils fear the fiends of the Abyss. Though demons yearn to sow chaos on the Material Plane, they show no gratitude when brought there, raging against their prisons and demanding release. Those who would risk summoning a demon might do so to wrest information from it, press it into service, or send it on a mission that only a creature of absolute evil can complete. Preparation is key, and experienced summoners know the specific spells and magic items that can force a demon to bend to another’s will. If a single mistake is made, a demon that breaks free shows no mercy as it makes its summoner the first victim of its wrath. The Book of Vile Darkness, the Black Scrolls of Ahm, and the Demonomicon of Iggwilv are the foremost authorities on demonic matters. These ancient tomes describe techniques that can trap the essence of a demon on the Material Plane, placing it within a weapon, idol, or piece of jewelery and preventing the fiend’s return to the Abyss. An object that binds a demon must be specially prepared with unholy incantations and innocent blood. It radiates a palpable evil, chilling and fouling the air around it. A creature that handles such an object experiences unsettling dreams and wicked impulses, but is able to control the demon whose essence is trapped with the object. Destroying the object frees the demon, which immediately seeks revenge against its binder. No matter how secure its bindings, a powerful demon often finds a way to escape an object that holds it. When a demonic essence emerges from its container, it can possess a mortal host. Sometimes a fiend employs stealth to hide a successful possession. Other times, it unleashes the full brunt of its fiendish drives through its new form. As long as the demon remains in possession of its host, the soul of that host is in danger of being dragged to the Abyss with the demon if it is exorcised from the flesh, or if the host dies. If a demon possesses a creature and the object binding the demon is destroyed, the possession lasts until powerful magic is used to drive the demonic spirit out of its host. Balors Figures of ancient and terrible evil, balors rule as generals over demonic armies, yearning to seize power while destroying any creatures that oppose them. Wielding a flaming whip and a longsword that channels the power of the storm, a balor’s battle prowess is fueled by hatred and rage. It channels this demonic fury in its death throes, falling within a blast of fire that can destroy even the hardiest foes. Barlgura The barlgura represents the savagery and brutality of the Abyss. Barlgura’s gather in packs to take down tougher foes, keep gruesome trophies from their victories, and decorate their territory with such objects. A barlgura looks like a hulking orangutan with a gruesome, drooping visage and tusks jutting from its jaw. Standing just under 8 feet tall, it has broad shoulders and weighs 650 pounds. It moves apishly along the ground, but it climbs with great speed and agility. Cambion A cambion is the offspring of a fiend (usually a succubus or incubus) and a humanoid (usually a human). Cambions inherit aspects of both parents, but their horns, leathery wings, and sinewy tails are hallmarks of their otherworldly parentage. Cambions grow into ruthless adults whose wickedness and perversion horrifies even the most devoted mortal parents. Even as a youth, a cambion identifies its rightful place as an overlord of mortals. It might orchestrate uprisings in towns and cities, gathering gangs of humanoids and lesser devils to serve it. A cambion forced to serve its fiendish parent does so out of admiration and dread, but also with the expectation that it will one day rise to a place of prominence. Cambions raised in the Nine Hells serve as soldiers, envoys, and personal attendants to greater devils. In the Abyss, a cambion carries only as much authority as it can muster through sheer strength and force of will. The demon lord Graz’zt is fond of procreating with humanoids who have made pacts with fiends, and he has sired many cambions who help him sow chaos across the multiverse. These cambions are characterized by charcoal-black skin, cloven hooves, six-fingered hands, and unearthly beauty. Chasme This loathsome demon resembles an unspeakable crossing of humanoid and fly. A chasme shuffles about on four spindly legs that can find purchase on walls and ceilings. A droning sound proceeds the approach of a chasme, inflicting foes with a terrible lethargy that leaves them open to attack. The lowly chasme serves more powerful masters as interrogators or taskmasters. A chasme lives to dole out torture and punishment, and has a knack for spotting demons that have deserted their lords. Capturing and returning such traitors allows a chasme to torment the victim without fear of reprisal. Dretch Dretches are among the weakest of demons – repulsive, self-loathing creatures doomed to spend eternity in a state of perpetual discontent. Their low intelligence makes dretches unsuitable for anything but the simplest tasks. However, what they lack in potential, they make up for in sheer malice. Dretches mill about in mobs, voicing their displeasure as an unsettling din of hoots, snarls, and grunts. Glabrezu A glabrezu takes great pleasure in destroying mortals through temptation, a
