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.
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.
