Commorragh - Geography of the Dark City: In the deepest depths of the Webway lies Commorragh, the primary home of the Drukhari. It is often called the "Dark City" by those who fear even to speak its name. But Commorragh is no mere city as Humans think of the term, since it makes even the largest of Mankind's hive cities seem to be no more than a termite mound in comparison to its mountainous bulk.Its dimensions would be considered outright impossible if Commorragh existed within the confines of the physical universe rather than the Webway. Commorragh is more like a vast, interlinked network of satellite Webway realms and cities linked by innumerable portals and hidden interdimensional pathways.In reality, the Dark City is a loose collection of far-flung Drukhari habitation nodes spread across the arteries of the Webway like a malignant cancer. Its nodal clusters are scattered at various points across the entire galaxy, thousands of actual light years apart. Yet these locations are linked together by shimmering interdimensional portals. As such, from the perspective within the Webway's confines, the immense distances between each of the different sub-realms of Commorragh can be crossed with but a single step, using the Labyrinth Dimension's non-Euclidean physics to teleport seemingly instantaneously across the stars.Commorragh appears within the Webway to be a composite urban centre on an impossibly vast scale, a hazy, contradictory realm whose dimensions can overawe the sanity of any who approach it. Thousands of starships dock each day at its spires, for the Drukhari are a far more numerous species than the Imperium of Man or even their own Craftworld Aeldari kin fully suspect.Yet Commorragh plays host to more than just the Drukhari kindred of the Aeldari. Many diverse species of alien mercenaries, bounty hunters and renegades all risk their souls to do business in Commorragh, hoping to claim just some of the riches to be had in the Dark City. The reaches of the interdimensional space around Commorragh are filled with the light-trails of spacecraft that pass between the Dark City and the Webway portals that surround it.Some of these gateways into realspace are small and dim, while those above the largest city-states of the realm are massive and can accommodate an entire pirate fleet with ease. A profusion of thorny dock-spurs juts from every spire and starscraper, holding Drukhari and other strangely-shaped xenos spacecraft fast in crackling violet beams of electromagnetic force.At present, Commorragh is an almost-infinite nest of architectural impossibilities and spatial anomalies. Each of its estates has been overdeveloped to the point that their growth has been forced into the vertical plane, the various regions sprouting upwards like needle-plants fighting for sunlight.Each of the Dark City's spires and starscrapers is linked to its fellows by curved arches and gossamer-like buttresses. Its kilometres-tall aeries and palaces both reach upwards and downwards simultaneously, spiralling into the depths of the Webway's curved space-time. With every Terran year that passes, the hideous city seeks to spread out over more of the dimension that serves as its foundation.
