"Light must be snuffed, perfection decayed, order dissolved, and minds fragmented."
— Creed of Tharizdun

Tharizdun, the Dark God, He of Eternal Darkness, is an evil deity of decay, insanity and darkness. He is part of the Greyhawk pantheon.



Unlike most deities of Oerth, who take humanoid shape, Tharizdun appears as a dark, amorphous form reminiscent of a sentient sphere of annihilation. Contact with the deity brings insanity and death, and no accurate surviving descriptions or depictions of him remain. [1][5]


With his goal of destruction, Tharizdun is Chaotic Evil. Historically, he has been considered Neutral Evil[1]. No beings have encountered Tharizdun for over a millennium, and his alignment can only be inferred from that of his insane followers.


Tharizdun is known by one name or another across countless worlds. He is called the Ebon God,[5] the Dark God, He of Eternal Darkness,[1] Lord of Decay,[6] the Ender,[7] the Patient One,[7] He Who Waits,[7] the Anathema,[7] the Father of Elder Evils,[7] the Author of Wickedness,[7] the Eater of Worlds,[7] the Despised,[7] the Undoer,[7] the Chained God,[8] and the Lost God[3].


Tharizdun is a evil god of eternal darkness, decay, destruction, entropy, malign knowledge, and insanity.[1].



Tharizdun's followers are united by a single ancient creed, found inscribed within one of his dark pyramids:

"Light must be snuffed, perfection decayed, order dissolved, and minds fragmented."[5]

The rest of his religion consists of a sporadic collection of terrible holy texts, secretly guarded even from other sects and detailing terrible rituals and extraplanar horrors.

The clergy of Tharizdun preach that all things eventually crumble, and in time Tharizdun's victory over the gods will be complete.[9]

Followers place great importance on the number three. For example, there are believed to be 333 Gems of Tharizdun, each an minor unholy artifact. Tharizdun's clerics cannot draw power from him unless they are in contact with an artifact such as these.


Tharizdun's few followers are almost all insane, and those who are not are extremely dangerous.[1] Contact with the imprisoned Dark God is only possible in proximity to one of his remaining artifacts or forgotten unholy sites, and even then his blessings come at the cost of madness.

Many cults are unaware that the entity that they worship is Tharizdun. Unable to act upon the world directly, he dispenses his power from cover identities and aspects, such as the Elder Elemental Eye responsible for the infamous Temple of Elemental Evil.

Tharizdun's followers are highly secretive, and his temples are well hidden. Many follow him in the optimistic belief that he will spare his loyal servants when he destroys the multiverse. Their goal is to bring together all of his artifacts, and to free the Ebon God from his imprisonment, where he will destroy the multiverse. Although the cult's leaders are fully aware of this, many low-ranking members merely seek revenge against society, and are unaware with the full extent of the Dark God's destruction, should he be freed.[10]

Tharizdun is followed by the Black Brotherhood, a dangerous sect of the Suloise Scarlet Brotherhood.[11]


Clerics of Tharizdun cannot gain spells from him in the normal way, due to his imprisonment on some unknown plane. They must be in contact with one of his few holy artifacts, or one of his ancient holy sites.

His clerics traditionally wear black or purple robes. Clerics of his aspect, the Elder Elemental Eye, typically wear ochre-colored robes, sometimes altered to represent one of the four elements.[12]

Many temples are led by charismatic high priests known as the Witnesses of Tharizdun, who live in opulent surroundings and partake in lavish food, drink, and other base desires at the expense of their underlings.[9][10] The leaders of the cult at the Temple of Elemental Evil are known as the Doomdreamers.[12]


Followers of Tharizdun conduct terrible rituals of sacrifice. Most of their rites involve failed attempts to commune with their deity, or learn the secrets to unlocking the chains that bind him.[1].


Tharizdun's cult is scattered across the world. He has cults in Verbobonc and southern Furyondy.[13]

His most dedicated followers are the Doomdreamers, a high-ranking caste of priests who receive visions from Tharizdun. They collect rare and esoteric knowledge, such as the names of demons.

Tharizdun is followed by the Black Brotherhood, a dangerous offshoot of the Scarlet Brotherhood. The majority of the Scarlet Brotherhood do not worship him, and he is not considered a Suel deity, at least not by the current Brotherhood. However, the Brotherhood intentionally spreads rumors to the contrary, sowing fear and misinformation among their enemies.[14]

Midnight Darkness, a cult of assassins dedicated to Nerull, god of death, is secretly led by Karniquaza, a follower of Tharizdun and member of the Scarlet Brotherhood.[15]

Holy sites[]

Those forgotten temples which survive are in dark, undergound places, kept freezingly cold by ancient magic placed by the fanatics who built them.[16] They make heavy use of black stone and an archaic trapezoidal building pattern. Newer temples to Tharizdun exist in the abandoned buildings of cities, disused sewer chambers, and the cellars of converts. A few operate more openly in remote wilderness areas where the locals are too few and too cowardly to challenge them.[9]

By far the greatest of Tharizdun's ancient temples was located in the Kron Hills of Oerth. In recent times, the forces of Tharizdun built a new temple on this most profane site, known as the Temple of Elemental Evil.[17] Wielders of a dark blade called Druniazth find themselves drawn here.[18]

In recent years, Tharizdun's cult built a new temple in an extinct volcanic crater in the Lortmil Mountains, known as the Temple of All-Consumption.[17]

A forgotten temple of Tharizdun exists in the Yatil Mountains on the world of Oerth. In cold chamber deep underground, called the black cyst, a black mist squirms within a floating hemisphere of black needlerock.[2]

A temple to Tharizdun exists in the Drachengrabs, a mountain range of Oerth.[3]

An ancient, but inert temple of Tharizdun survives in Erelhi-Cinlu, the drow city. It is located in the Ghetto of Foreigners, and resembles a black ziggurat.[19]

The frozen ruins of a temple to Tharizdun exist in a vast cavern in the underground waterways beneath the town of Narwell. Its entranceway is in a massive demonic face, sixty feet tall, and permanently frozen over with ice.[16]

Another ruined temple is located in the Jotens, a mountain range of Oerth.[18]

There is a temple to Tharizdun hidden in the Free City of Greyhawk. Another exists in the sewers below Verbobonc, whose membership numbers 55. It is led by Damargath, a human cleric/fighter from the cult's Greyhawk chapter.[10]

A temple exists near the upper Jewel river, from which occasionally pour forth horrible giant beetles with skeletal heads. The beetles are mutated by feeding on the waste of otyughs within the temple, who possess horrible tentacles and beaks like that of a grell.[20]

The Ziggurat of Black is an ancient tower in the Tilvanot Pensinsula, constructed of flat black metal. No entrance to the ziggurat has been found.

It is rumored that a temple of Tharizdun exists in the Gull Cliffs. The albino gnomes beneath the hills here are said to dig caverns to steer visitors away from the temple.[21]

A false rumor claimed that an abandoned shrine to Tharizdun existed in Veluna City.[22]

Holy days[]

The followers of Tharizdun are few and secretive, and most people do not even know that he was once worshiped. If he has holy days, they are unknown to all but perhaps some of his followers.

Holy symbol[]

Tharizdun's holy symbol is a jagged counterclockwise dark spiral rune known as the Spiral of Decay.

Some of his clerics also use a two-tiered inverted ziggurat, known as the Obex.[23]

Under the aspect of the Elder Elemental Eye, his holy symbol is a downward-pointing black triangle with an inverted yellow Y within it. His followers under that identity also use a symbol of a golden flaming eye.[24]

Favored weapon[]

In as far as the enigmatic Tharizdun favors any one weapon, most concur that it is the dagger, and followers of the Dark God often carry sharp, curved daggers with which they conduct terrible rituals of sacrifice.[5]

At least one sage belives that Tharizdun himself wields the Spiral of Decay represented in his holy symbol, for which no equivalent weapon exists in human knowledge.[1] Yet another (almost certainly insane) source claims his weapon to be something called a "Check Toee".[25]



Tharizdun is hated by nearly all other gods, who would gladly put aside their differences to stop the Dark God from escaping his demiplane prison.

Rao, god of light, is particularly opposed to Tharizdun. Rao's followers believe that the Crook of Rao was originally crafted by that god for the purpose of banishing Tharizdun's dark forces.

Boccob, god of magic, actively opposes Tharizdun and works to ensure that he remains imprisoned. The power of magic is very gradually waning in the world of Oerth, and Boccob suspects that Tharizdun is responsible.[26]


Tharizdun has no allies among the gods. The evil Archomentals, five powerful beings believed to be his offspring, are possible allies in his plots, and were intended to be accomplices during The Return to the Temple of Elemental module.


Avatars and proxies[]

Tharizdun's greatest servant is Shothragot, the Herald of Tharizdun[27], a disconnected avatar of the Dark God. It is a massive sphere of black tar, buried beneath the world for a thousand years.[7]


The black cysts are amorphous spheres of pure blackness, formed from the coagulated nightmares of sleeping Tharizdun. These creatures grow as cultists perform ritual sacrifice to it. Reality warps in its wake.[7]

The elhoriads are blackened, undead skeletons with a deadly entropic touch. They are typically used to guard temples, and were created by the cult by combining the art of necromancy with the power of one of Tharizdun's dark artifacts.[28]


The cult of Tharizdun possesses numerous artifacts and lesser magic items sacred to the Dark God, and devotes considerable resources to finding more. Even fragments of destroyed artifacts are priceless to the cult, since clerics cannot receive spells from Tharizdun without being in proximity to such an artifact. Many items crafted more recently are etched with a vortex symbol.[29]

Lament for Lost Tharizdun is a book bound in black scaly hide, written in silver ink on black paper. Merely reading this text is damaging to the mind of any but the mad followers of Tharizdun. It is presumed to have been written by one of his followers after the deity's banishment.

Tharizdun's followers seek to reclaim the 333 Gems of Tharizdun, a collection of gemstones sacred to the Dark One, sacrificed to him by cultists in ages past. Mostly looted or sold off after Tharizdun's imprisonment, they have spread across the world by traders unaware of their connection to that evil deity.

The Spear of Sorrow, a cursed polearm seven feet in length and carved entirely from black stone, is sacred to Tharizdun. Its purpose is to locate and restore that god's ancient and forgotten temples and awaken his sleeping guardians.[30]

Druniazth, the Claw of Tharizdun, is a sword made from black ruinite metal by cultists centuries after his banishment. Its purpose is to spread a prophecy of Tharizdun's return, and ultimately to unleash him upon the world.[18]

The Weeping Hexgram, discovered near the Ziggurat of Black in the year 576 CY, is a ten foot diameter black iron ring inset with a bowed hexagram, which seeps blood when exposed to sunlight. In 581 CY, a paladin of Heironeous broke the ring into three pieces.[31]

Over a thousand years ago, Tharizdun gifted the Scorpion Crown to Shattados, king of the empire of Sulm.[6]


Tharizdun has been imprisoned in a distant demiplane for longer than anyone can remember. Its location in the multiverse is a closely guarded secret, even among gods.

It is speculated that the Dark God floats powerlessly through the Astral Plane, all but dead due to lack of followers.[32]

Tharizdun is speculated to be the malign entity known to be trapped within the Demiplane of Imprisonment, a massive mile-wide crystal floating through the Ethereal Plane. That plane's prisoner is an insane entity from another reality dedicated to the destruction of all things, his nightmarish thoughts occasionally bubbling through and leaking into the dreamscapes of his worshipers.[33]



In a time before surviving record, forgotten temples of Tharizdun were built by evil cultists of that dark god, who gathered in his name to undertake terrible deeds. Tharizdun and his servants grew ever more powerful, until the other gods set aside their differences and colluded to banish his presence from the world. Tharizdun has been imprisoned in some unknown demiplane ever since.[23]

Ancient history[]

The ancient Flan people knew of Tharizdun. Around -700 CY, the ruler of Sulm invoked the Dark One in hopes of uniting his feuding subjects. Instead, his people mutated into scorpion-like monsters, and his realm decayed into a desert.

The ruined Suel Imperium of Oerth knew of Tharizdun and considered him a god of magic and mysteries.[4]

Although Tharizdun still has limited influence outside of his demiplane of imprisonment, he has not been heard from for over a thousand years.[1]. Tharizdun's servants last called forth his avatar in the year -422 CY, during the Twin Cataclysms which destroyed the Suel Imperium and Baklunish Empire.[7]

Recent history[]

Cultists of Tharizdun made ritualized attempts to contact their imprisoned deity, but over centuries they became disillusioned and complacent. The followers at his temple beneath the Yatil mountains gradually embezzled the sacred 333 Gems of Tharizdun by replacing them with less valuable gemstones, and the last of his high priests there died over a hundred years ago.[2]

Numerous smaller cults have risen since then. In 591 CY a cult to the Elder Elemental Eye, an alias of Tharizdun, captured the Temple of All-Consumption.[23]

Myths and legends[]

The Book of Incarum, holy text of the church of Rao, tells that Rao is the creator of mankind. Humans in ancient times turned to Tharizdun for magical power, and brought upon an era of despair and eternal night. Rao created the two moons of Oerth to create light for those who repented, and sent his servant Incarum with the Crook of Rao to cast out the forces of Tharizdun from the world.[22]

Creative origins[]

D&D creator Gary Gygax named Tharizdun after Tharzduun or Tharzdu'un, a deity created by Rob Kuntz.

"I contributed the idea for Tharizdun by informing Gary of my Dark God, Tharzduun."
— Rob Kuntz

It is speculated that this was in turn inspired by the deity Thasaidon, from the works of Clark Ashton Smith. A quote from that author's work The Eldritch Dark appears in the introduction to Return to the Temple of Elemental Evil (2001).
