Commorragh

In the science fiction miniature game Warhammer 40,000, Commorragh is the dark city of the fictional race Dark Eldar. It is said to be impossible for outsiders to find, and anarchy and terrorism are a well-established way of life for its debased inhabitants. It is widely believed to be hidden deep within an inter-dimensional labyrinth known as the Webway. During the final weeks of the recent Eye of Terror campaign which followed the 13th Black Crusade of the chaos lord Abaddon the Despoiler, the Eldar collapsed the Webway portal in which Commoragh was located, effectively destroying the entire planet.

It is also spelled 'Commorragh'.
