What Is Commorragh? — The Dark City Explained

Part of our Drukhari hub: every Drukhari guide, lore page and painting tutorial in one place.

Commorragh is the massive Dark City hidden within the Webway — a sprawling, impossible metropolis of spires, arenas, and torture chambers that serves as the home of the Drukhari (Dark Eldar). It is not a city in any conventional sense. Commorragh exists in a pocket dimension within the Webway, a space between realspace and the Warp where the laws of physics are suggestions rather than rules. The city has grown over millennia into a structure so vast that it dwarfs most planets, a labyrinthine horror where billions of souls suffer to keep the Drukhari alive.

Understanding Commorragh is essential for understanding the Drukhari. The Dark City is not merely where they live — it is what they are. Everything about Drukhari culture, politics, and survival is shaped by Commorragh’s unique nature. The city feeds them, protects them, and defines their entire civilisation. Without Commorragh, the Drukhari would cease to exist. With it, they are one of the most dangerous and terrifying factions in the Warhammer 40,000 universe.

Where Is Commorragh Located?

Commorragh exists within the Webway — the ancient network of tunnels through the dimension between realspace and the Warp. It does not occupy a fixed point in the material galaxy. Instead, it exists in a vast pocket of sub-dimensional space that has been expanded, modified, and reinforced over millennia by the Drukhari and their Aeldari predecessors.

The city is connected to realspace through numerous Webway gates — portals that allow the Drukhari to emerge anywhere in the galaxy where a gate exists. This network of gates is what makes Commorragh so strategically significant. From their hidden city, the Drukhari can launch raids against worlds across the galaxy, striking without warning and retreating through their gates before any meaningful response can be organised. The gates are closely guarded secrets, and the Drukhari maintain a vast intelligence network to monitor and protect their access points.

Commorragh’s location within the Webway also provides its most important form of protection. Because it exists outside realspace, conventional military forces cannot reach it. You cannot fly a fleet to Commorragh — there is no star system to navigate to, no planet to orbit, no coordinates to plot. The only way to reach the Dark City is through the Webway, and the Drukhari control the gates. This makes Commorragh virtually impregnable against external attack, a fortress hidden in the folds of reality itself.

How Big Is Commorragh?

Commorragh defies conventional measurement. It is not a single structure but a conglomeration of thousands of sub-realms, satellite dimensions, and stolen fragments of realspace that have been incorporated into the city over millennia. Some estimates suggest that Commorragh’s total volume exceeds that of many star systems, though such comparisons are inherently imprecise when dealing with sub-dimensional spaces where geometry does not behave normally.

The city is organised (to the extent that it is organised at all) around several major features. High Commorragh is the upper realm, where the most powerful Archons maintain their fortress-palaces and the Kabals compete for dominance. The spires of High Commorragh are impossibly tall and impossibly slender, piercing the void of the Webway like needles. Low Commorragh is the sprawling underbelly, a lawless labyrinth of slums, fighting pits, and black markets where the city’s underclass lives, fights, and dies. The Null Zones are abandoned or unstable regions of the city where reality is thin and the Warp threatens to breach the Webway’s walls.

Perhaps the most famous features of Commorragh are its arenas. The Wych Cults of the Drukhari maintain vast gladiatorial arenas where slaves, beasts, and warriors fight for the entertainment of the populace. The largest of these arenas can seat millions of spectators, and the spectacles staged within them range from simple one-on-one duels to elaborate recreations of historical battles complete with terrain, exotic creatures, and environmental hazards.

The city also contains the Haemonculi lairs — the flesh-crafting workshops of the Haemonculi Covens, where the Drukhari’s master torturers and bio-engineers ply their trade. These lairs are places of unspeakable horror, where living beings are dissected, reassembled, and transformed into nightmarish creations. The Haemonculi are the closest thing the Drukhari have to doctors and scientists, and their lairs serve as both laboratories and torture chambers — often simultaneously.

Why Do the Drukhari Need Commorragh?

The Drukhari need Commorragh because it protects them from Slaanesh. When the Aeldari civilisation collapsed and the Chaos God Slaanesh was born from their collective psychic excess, every Aeldari soul became Slaanesh’s rightful prey. The Craftworld Aeldari protect themselves through discipline, psychic discipline, and the Spirit Stones that capture their souls at death. The Drukhari protect themselves through a very different method: they steal the life force of others.

Every Drukhari is slowly dying. Slaanesh constantly drains their souls, a gradual withering that would eventually consume them entirely if left unchecked. To counteract this drain, the Drukhari must absorb the suffering of others — literally feeding on pain, terror, and anguish to replenish their own fading life force. This is not a choice or a cultural preference. It is a biological necessity. A Drukhari who does not feed on suffering will age, wither, and eventually have their soul consumed by Slaanesh.

Commorragh facilitates this feeding on a civilisational scale. The city is, in essence, a vast farm for suffering. Millions of slaves are kept in perpetual torment, their pain harvested by the Drukhari through both physical proximity and specialised technology. The arenas provide mass entertainment that doubles as mass feeding. The Haemonculi’s lairs produce suffering so concentrated that it can sustain entire Kabals. Every aspect of Commorragh’s culture — the gladiatorial games, the slave raids, the casual cruelty, the political backstabbing — serves the fundamental purpose of generating enough suffering to keep the Drukhari alive.

The city’s location in the Webway is also critical. The Webway provides a degree of insulation from Slaanesh — the god’s influence is weaker within the Webway than in realspace or the Warp. Commorragh’s position deep within the Webway means that the drain on Drukhari souls is slower here than it would be elsewhere, buying them more time between feedings. This is why the Drukhari remain in Commorragh rather than establishing settlements in realspace — the city is their refuge, their hunting ground, and their life support system all in one.

Who Rules Commorragh?

Commorragh has no single ruler. The city is controlled by a constantly shifting web of power blocs, alliances, and rivalries that makes Imperial politics look straightforward by comparison. The three primary power structures are the Kabals, the Wych Cults, and the Haemonculi Covens.

The Kabals are the primary political and military organisations of Commorragh. Each Kabal is led by an Archon — a Drukhari of enormous personal power, cunning, and ruthlessness who has fought, schemed, and murdered their way to the top. The Kabals control territory within the city, maintain private armies, and organise the slave raids into realspace that provide the city’s essential supply of suffering. The most powerful Kabal in Commorragh is the Kabal of the Black Heart, led by Asdrubael Vect — the closest thing Commorragh has to a supreme ruler.

Asdrubael Vect is arguably the most cunning and dangerous individual in the entire Warhammer 40,000 setting. He has ruled the Kabal of the Black Heart for millennia, maintaining his position through a combination of political genius, ruthless violence, and an unmatched understanding of Commorragh’s power dynamics. Vect did not inherit his position — he was born as a slave and rose to dominate the Dark City through sheer force of will and intelligence. He has survived (and orchestrated) countless assassination attempts, political upheavals, and external invasions, emerging stronger from each one.

The Wych Cults control the arenas and provide Commorragh’s martial entertainment. Led by Succubi — warrior-queens of extraordinary combat skill — the Wych Cults are both entertainment providers and elite military units. Their gladiatorial displays serve the dual purpose of feeding the populace and training some of the galaxy’s deadliest close-combat fighters.

The Haemonculi Covens control the city’s biological infrastructure — cloning, resurrection, flesh-crafting, and the most refined forms of torture. The Haemonculi are ancient beings who have extended their lives through dark science and Warp-craft, and their knowledge of biology, pain, and the interface between the two makes them indispensable to Drukhari society. They can bring the dead back to life (for a price), reshape bodies to any specification, and create biological weapons of staggering cruelty.

What Are Slave Raids?

The slave raids are the Drukhari’s primary method of obtaining the suffering they need to survive. Raiding parties emerge from Webway gates across the galaxy, attack vulnerable populations, capture as many living beings as possible, and retreat to Commorragh before any significant military response can be organised.

These raids are conducted with terrifying efficiency. The Drukhari are masters of lightning warfare — fast, precise, and overwhelmingly violent. A typical raid involves fast-moving skimmer vehicles, aerial gunships, and infantry equipped for rapid assault and withdrawal. The goal is not to conquer territory or defeat military forces but to seize captives and inflict maximum terror in the shortest possible time.

The victims of these raids face a fate that most inhabitants of the 40k universe would consider worse than death. Captured slaves are brought to Commorragh, where they are distributed among the Kabals, Wych Cults, and Haemonculi Covens. Some are put to work as labourers. Some are thrown into the arenas to fight and die for entertainment. Some are given to the Haemonculi for experimentation. All of them suffer, and all of their suffering feeds the Drukhari.

The scale of the slave raids is staggering. Commorragh’s population requires a constant influx of new victims — the existing slave population is consumed through labour, arena combat, experimentation, and simple cruelty faster than it can reproduce. This means the Drukhari must raid constantly, targeting worlds across the galaxy to maintain their supply of suffering. Some estimates suggest that billions of beings are taken to Commorragh every century, drawn from every species and every corner of the galaxy.

What Are the Dangers of Commorragh?

Commorragh is one of the most dangerous places in the entire Warhammer 40,000 universe, even for its own inhabitants. The Drukhari live in a state of perpetual paranoia, and with good reason — betrayal, assassination, and casual violence are so common in the Dark City that they constitute the normal social fabric.

Every Drukhari is a potential threat to every other Drukhari. The Kabals are in constant competition, and advancing within a Kabal typically requires removing whoever currently holds the position you want — usually through murder. Archons must constantly guard against assassination by their own subordinates, rivals from other Kabals, and freelance killers hired by anyone with a grudge or an ambition. The life expectancy of a Drukhari who lets their guard down is measured in hours.

Beyond political violence, Commorragh itself is hazardous. The city’s growth has been organic and unplanned, resulting in vast areas of unstable architecture, toxic environments, and reality-thin zones where the Warp threatens to breach. Creatures from the Warp or from the darkest corners of the Webway occasionally infiltrate the city, and entire districts can be lost to incursion before the Drukhari can respond. The city’s infrastructure is maintained through slave labour and ancient technology, both of which are unreliable.

The most catastrophic threat is a full Warp breach. Commorragh’s position in the Webway provides some protection from Slaanesh, but the city’s boundaries are not perfectly sealed. On several occasions in the lore, Warp rifts have opened within Commorragh, flooding sections of the city with daemons and Warp energy. These incursions are existential threats — if the breaches cannot be sealed, Commorragh’s entire population would be exposed to Slaanesh’s full attention, with catastrophic consequences.

What Is Commorragh’s History?

Commorragh’s origins predate the Fall of the Aeldari. Before the catastrophe that birthed Slaanesh, Commorragh was already a major Webway port — a trading hub and transit point where Aeldari from across the galaxy gathered to do business. It was one of many such ports in the Webway, distinguished mainly by its size and its reputation for decadence.

As the Aeldari civilisation descended into the hedonistic excess that would eventually create Slaanesh, Commorragh became a centre for the most extreme pleasures and indulgences. The most debauched elements of Aeldari society gravitated toward the Dark City, where the Webway’s insulation from the Warp allowed them to indulge without (they believed) consequence. When the Fall came and Slaanesh was born, those Aeldari who were within Commorragh survived — the Webway’s barrier protected them from the psychic shockwave that consumed the rest of their civilisation.

These survivors became the Drukhari. Cut off from the spiritual practices and psychic disciplines of the Craftworld Aeldari, they were forced to find their own way to resist Slaanesh’s soul-drain. The solution they discovered — feeding on suffering — shaped their entire civilisation and transformed Commorragh from a trading port into the nightmare city it is today.

Over the millennia since the Fall, Commorragh has grown enormously. The Drukhari have expanded the city by conquering and incorporating sub-realms within the Webway, capturing fragments of realspace and pulling them into the city’s dimensional fabric, and building new structures at a frenetic pace. Entire stolen suns have been chained within Commorragh to provide light and energy, their nuclear fires held in stasis by ancient technology. The city has absorbed so many sub-realms that its internal geography is effectively unmappable — a three-dimensional maze that would take lifetimes to explore.

Frequently Asked Questions

Can outsiders visit Commorragh?

Outsiders do not “visit” Commorragh — they are brought there as slaves. However, some exceptions exist. Rogue Traders and other bold or foolish individuals have occasionally entered Commorragh for trade or negotiation, though doing so is extraordinarily dangerous. The Harlequins can access Commorragh through the Webway, and they are one of the few groups the Drukhari tolerate.

How many people live in Commorragh?

The exact population is unknown, but it is believed to number in the billions — possibly tens or hundreds of billions when slaves are included. Commorragh is by far the largest concentration of Aeldari in the galaxy, with more Drukhari living in the Dark City than all the Craftworlds combined.

Has Commorragh ever been invaded?

Yes. The most significant invasion was the Dysjunction, a massive daemonic incursion that tore through the city when a captured sun went supernova and breached the Webway’s walls. Asdrubael Vect ultimately sealed the breach, but the invasion caused enormous destruction and reshaped the city’s political landscape. Various smaller incursions have occurred throughout the city’s history.

Could the Imperium destroy Commorragh?

Almost certainly not. The Imperium does not know exactly where Commorragh is, cannot navigate the Webway to reach it, and would face the combined might of the entire Drukhari civilisation if it somehow managed to find a way in. The Dark City’s location in the Webway makes it effectively invulnerable to conventional military assault.

Is Commorragh bigger than a planet?

In terms of volume and population, Commorragh is believed to exceed most planets. However, it is not a solid body — it is a three-dimensional structure of spires, platforms, and sub-realms spread across a pocket of sub-dimensional space. Comparing it to a planet is like comparing a city to a mountain — they are fundamentally different types of structures.

What does Commorragh mean?

Commorragh is the name of the Dark City, the Webway home of the Drukhari. Games Workshop has never published a translation of the word in the lore, so it works as a proper name, like Macragge or Baal. It refers both to the city’s central core and to the whole sprawl of sub-realms joined to it over the millennia.

What are the Ilmaea?

The Ilmaea are the stolen suns that the Drukhari hold captive above Commorragh. They light the Dark City and feed it energy, and their dying light gives Commorragh its sickly, eternal twilight. The Ilmaea are the stolen suns mentioned in the city’s history, chained in place by ancient technology.

Is Commorragh the same as the Webway?

No. The Webway is the vast labyrinth dimension that runs between realspace and the Warp, built long ago by the Old Ones. Commorragh is a city inside it, the largest and most infamous of the Webway’s ports. The Drukhari use Webway gates to strike anywhere in the galaxy and then vanish back to Commorragh.
