Koronus Expanse

The Koronus Expanse, also known as the Koronus Sector[4], is the name given by Imperial authorities to a dangerous unexplored region of the Halo Stars beyond the Calixis Sector.[1a]
Overview
The Expanse is accessed via the Koronus Passage, a treacherous but navigable route through the great warp storms that bar the passage to the Halo Stars beyond the way station of Port Wander.[Needs Citation]
As is true of the Calixis Sector itself, the Expanse was untouched by the God-Emperor's Crusade many millennia ago and so it is a realm of fearsome xenos, treasures beyond imagining, heathen worlds of men, and the echoes of the ancient doom.[1a]
History
The Koronus Expanse's history is largely defined by the actions of the Rogue Traders who survived exploring it. However, its written history is full of apocryphal records, and oral history regarding the region often comes from unreliable narrators as well, making a definitive recounting practically impossible.[2a]
The Calixis Sector was first charted during the Age of Apostasy by Solomon Haarlock, though fragmented naval records indicate that it was actually first charted by a prior Explorator fleet belonging to the Adeptus Mechanicus. The method of traversing the field of intense warp storm activity in what is now the Drusus Marches subsector was missing from both sets of data, however, and so the Imperium designated the storm field as the farthest border of the Sector.[2a]
73 years after the Imperial Navy constructed the space station Port Wander near the storm field, a Rogue Trader named Purity Lathimon discovered "the Maw", a safe passage through the storms. However, rather than returning to the Expanse, she sold her knowledge on and departed Calixis, never to return. The Koronus Expanse was effectively declared part of the Calixis Sector by the High Lords of Terra.[2b]
Several worlds in the Expanse are colonised, while others were destroyed. The destruction was largely caused by the Inquisitor Kobras Aquairre, who eventually leds his fleet into the Rifts of Hecaton and vanished. Aeldari and other, even more mysterious xenos species were discovered in the Expanse.[2c]
Rogue Traders and their involvement
For centuries, Rogue Traders have braved great evils and the treacherous warp to venture into the Koronus Expanse, but their efforts have barely begun to uncover its secrets. Footholds have been built close to the few semi-stable warp routes into the area.[1a]
Here, resources-rich worlds are exploited, xenos ruins, trade envoys meet with heathen lords, and colonies are attempted upon sheltered worlds. This effort has been enough to shower wealth and fame upon the fortunate and make corpses of the rest. The gateway to the Expanse is littered with broken vessels and tales of the vanished.[1a]
Current State
The Koronus Expanse in the 41st Millennium is a scattered, partly explored region containing a few young colonies and vast natural wealth still barely explored.[1a]
Rogue Traders vie with one another for known resources, heedless of lives lost in the pursuit of riches, while a tentative attempt at Imperial colonization follows in their wake.[Needs Citation]
Drawn by the flow of wealth, pirates and servants of Dark Gods have also slipped into the Expanse, eager to cast destruction upon the works of the God-Emperor's faithful, living by what they wrest from dead hands, while the Expanse itself holds many secrets and native inhabitants no less dangerous. Beyond these human conflicts lie truly dark and dangerous voids, rife with rumoured terrors, undiscovered stars, and worlds of man who have never known the God-Emperor. There are no defined warp-routes, no safe ways through the swirling empyrean. These regions hold the fearsome Ork, the treacherous Aeldari, and strange ruins that lie beneath the light of dying stars.[1a]
Galactic Landscape
Corewards of the Koronus Expanse lies the Calixis Sector which is accessible by the Koronus Passage, often using The Stations of Passage as real space way stations between Warp jumps.[3]
Warp Routes
The warp space of the Koronus Expanse is treacherous and unknown in the main, and partially explored regions of the Expanse are islands of Imperial activity amidst a vastness of danger and mystery. Navigating is a far cry from traversing the established warp routes of the Calixis Sector.[1a]
Most of the Koronus Expanse is known to the Imperium only through legend, revelation, and hearsay. The Rogue Trader who ventures into this unknown risks his very soul upon the talent of his Navigator, and on quality of what little information he has gleaned from those gone before.[1a]

Unknown Regions
Beyond the partly explored regions of the Koronus Expanse, past deeps beset by pirates and dread xenos, lie many worlds and strange phenomena which exists as the stuff of dark legend. Some of these uncharted stars were visited by a single Rogue Trader whose tales are doubted and dismissed by rivals as outright lies, while others are known only from dubious and apocryphal sources such as Thulean data-vaults recovered from Dolorium's voids in 741.M41, or the infamous prophetic visions of the Seven Witches of Footfall.[1a]
Other fragments of contradictory lore relating to these dark zones are culled from even more untrustworthy sources, such as the muted Astropathic whispers overheard on the warp's twisted eddies, the falsehoods of the deceitful Eldar, or the ancient myths of heathen worlds given over to darkness for millennia uncounted.[1a]
Such areas are only labelled only as "Here be monsters" on ancient charts, where only the foolhardy or insane would venture to seek their destiny.[1a]
