A Haemonculi Coven is a self-governing organization composed of Haemonculi, the most evil creatures in Commorragh. Haemonculi Covens can be compared to Incubus sects or Wyches who from time to time co-operate with the Kabals of the Dark City.
Haemonculi Covens consist of Haemonculi, attended by their their crazy and twisted creations, such as Wracks and Grotesques.
Underneath Commorragh there are as much spires and edifices as at the top. These are clustered into confusing, anarchic profusion, many hollowed out by controlled acts of destruction until they form up cavern-like lairs.
The Underworld of the Dark City is an exceptionally dangerous place (even by the standards of Commorragh, which as a whole is one of the most dangerous places in the galaxy). Inside the Underworld, Haemonculi of like mind gather into covens, each of which occupies a vast demesne of cells and laboratories. It is in here, deep beneath the Dark City, where diabolical figures of Haemonculi meld flesh and create their pieces of art.
The hierarchy in Haemonculi Covens is not known, although it is highly possible that there is one Master Haemonculus, or Haemonculus Ancient, in each Coven.

The Prophets of Flesh
The Prophets of Flesh are one of the most powerful Dark Eldar Haemonculi Covens of Commorragh. Under the command of the ancient Haemonculus Urien Rakarth, the Coven has demonstrated special interest in converting non-Dark Eldar aliens such as Tau into hideous Grotesques. They are allies of the Supreme Overlord of Commorragh, Asdrubael Vect, and the Prophets of Flesh have fought alongside the Kabal of the Black Heart in devastating joint real-space raids.
Coven of the Thirteen Scars
The Coven of the Thirteen Scars is a Dark Eldar Haemonculi Coven. It is notable for the Tower of Flesh, the Coven's main stronghold in Commorragh and a living organism made from the flesh of those who defied the Thirteen Scars. It is said that Fabius Bile tutored under the dark arts of the flesh in the Tower.
