Caligari Sector - History: The Caligari Sector is a vast region located in the fringes of the Segmentum Tempestus on the southern rim of the galaxy. Despite its tremendous size and the countless resources the worlds of the sector have to offer, the territory has been largely ignored by the Imperium at large for many Terran millennia, and even experienced Rogue Traders tend to scoff at travellers supposedly hailing from this area.The Caligari Sector is separated by great distances from the Segmentum Solar and, compared to more significant Imperial sectors, it could be justly claimed that it is sporadically populated. It is a shattered territory, where thriving star systems alternate with lost regions, quarantine zones and uncharted areas plagued by strange anomalies. However, over the centuries it has gradually become an extremely important area of operation for the Inquisition.This far from the light of the Astronomican, shadows gather, and dark corners hide ancient secrets and dangerous creatures. In the Caligari Sector, heretical ideas tend to spread freely, not to mention a steady flow of newcomers from the heartlands of the Imperium who bring dubious agendas or questionable dogma with them, hoping to find refuge among the flickering stars of the galactic rim.In other words, the Caligari Sector is an extremely ripe hunting ground for the Inquisition, and the Caligari Conclave of Inquisitors wields far more power -- and employs a significantly greater number of Acolytes and agents -- than might be expected.There are ample reasons why this region is so difficult to reach and control. In addition to the distance from Holy Terra, large sections of the Caligari Sector have been frequently cut off from the Imperium by the region's infamous Warp surges. These have been a clear and present danger since the arrival of the first scouts seeking out new worlds for Mankind. Certain local sects of the Adeptus Mechanicus, and some Navigator families, have dedicated centuries to studying the Caligari Warp surges, but information on them remains scarce and controversial...or simply classified.These Warp surges could be categorised as smaller equivalents of the huge, whirling Warp storms that manifest throughout the galaxy, such as the Maelstrom or the Eye of Terror. Warp surges are relatively small empyric anomalies, but they appear frequently, sometimes without warning, and they can last for an indeterminable amount of time, rising and abating, and blocking established Warp travel routes. Some surges disappear in solar weeks, but others can linger for decades.Warp surges can cut off star systems or, in extreme cases, even large portions of an entire sub-sector. Consequently, there are always a huge number of unreachable systems in the sector, and this is why the Caligari Conclave keeps a close eye on the affected territories.Some systems suffer only minor inconveniences during these periods of undesirable separation, while other systems spend far too long behind the impenetrable wall of storms, and when contact is reestablished, whole worlds have succumbed to heretical ideology, fallen victim to foul xenos raids, or encountered the forces and servants of Chaos. In extreme cases, there are even worlds that have forgotten that they used to be part of the glorious Imperium of Man. On these worlds, Inquisitors find hive cities on the verge of total annihilation, consumed by their own starving population, shrieking to new, alien gods for redemption. On Shrine Worlds, Imperial statues have been knocked down to erect false marble idols in their place. Inquisitors do their best to pacify these reclaimed territories, but their work is difficult and unforgiving.The Warp surges present a clear and present danger in the sector, and Navigators, Imperial fleet commanders and Rogue Traders have learned to cope with these anomalies over the centuries. Recently, however, the Caligari Warp surges have started to exhibit disturbing signs -- mere impediments suddenly turning into full-blown, unholy ruptures in the Immaterium, distorting space and time locally, and spitting out the Daemonic filth of Chaos into realspace. It is almost as if a colossal tide had torn across the galaxy, destabilising the Warp and everything within it...
