Screaming Vortex - Screaming Vortex: The Screaming Vortex is a permanent Warp storm and Warp rift that is one of the zones within the region known as the "Great Warp Storms" that separates the Calixis Sector of the Segmentum Obscurus from the Koronus Expanse region of the Halo Stars.It takes the form of a vast, seething cauldron of empyreal energies which, while not as large, are every bit as intense as those spewing forth from the Eye of Terror, the Maelstrom, the later Great Rift during the Era Indomitus, or any other such Warp/realspace overlap in the Milky Way Galaxy.As a permanent Warp storm and Warp rift, the Screaming Vortex is a region of space beset by the unreal forces of the Empyrean, where the thin skein between reality and that impossible dimension has been torn viciously asunder. A volume of space far larger than the average Imperial sector is to all intents and purposes cut adrift from the physical universe, the laws of nature no longer applying within.Little is know about the region in the Imperium. The scholars and Navigators of Scintilla, the capital world of the neighbouring Calixis Sector, have only been able to garner a few bare physical details about the great Warp storm. Its physical size is unknown, as it fluctuates rapidly and randomly in its region of space with no discernible pattern. Its gravitational pull has been measured anywhere from -3.2 G all the way to an incredible 7,021,475,403 Terran gravities. Its temperature also fluctuates wildly, having been measured from -274 to 100,000,000+ degrees Celsius -- hotter than the cores of many stars.As a result of such extreme conditions, the conventional wisdom of the Navis Nobilite representatives on Scintilla is that nothing beyond the entities already native to the Immaterium can survive within the Screaming Vortex. Yet they are wrong, for those among mortals who serve the Dark Gods of Chaos are welcomed within the Warp rift's confines.Beyond the boundaries of the Screaming Vortex, the Ruinous Powers of Chaos hold sway and for a mortal to even contemplate crossing into its weirdling energies is insanity of the very worst kind. The interior of the vortex's heart cannot be described in terms that even the greatest mortal mind could comprehend, and so descriptions are largely limited to the worlds on its verges and, when describing those places further in, to allegory and myth.The Screaming Vortex is so named because the ebb and flow of its tides are accompanied by a concomitant wailing, audible only to psykers and sorcerers. The most gifted of psykers can hear the ceaseless, discordant psychic wailing that emanates from the vortex from dozens, sometimes hundreds, of light years away, their dreams haunted by once-beautiful faces turned ashen by fear and shrill, plaintive screams for mercy.The closer those gifted in the psyker's arts travel to the Screaming Vortex, the louder and more desperate the screaming becomes. Soon, it is not only in their dreams but in their every waking hour that the psyker hears the wailing, and most are driven to the very brink of sanity by the experience.On occasion, such as when the tides of the gibbous storm wax, the screams are so loud that even those born without the cursed power of the psyker can hear them, scratching at the edge of their sanity and seeming to beg them for a mercy that none have the power to grant.
