Calixis Sector

“It is an ill omened place, my lord. Cursed, they say, a fount of witches and other foulness. A chalice of corruption, haunted by a dead sun. They say it is but a matter of time before the stars align and the entire place is torn asunder by Daemons. Of course, they say that about a great many places. But in this case, master, the Tarot indicates it is actually true.” — Diviner Adept Harpious Mundis.

The Calixis Sector is a sector of the Milky Way Galaxy that serves as the setting for the Warhammer 40,000: Dark Heresy role-playing game, which focuses on the actions of Imperial Inquisitors and their chosen Acolytes and Throne Agents. The Calixis Sector is an Imperial sector located in the Segmentum Obscurus on the northern edge of the known galaxy, near the Halo Stars and the Eye of Terror. To the trailing edge of the galaxy, the Calixis Sector is bordered by the hazardous territories of the Fydae Great Cloud and to spinward by the Scarus Sector. Bordering to coreward of the galaxy, its nearest neighbour is the Ixaniad Sector. To rimward lie the contested and unregulated Imperial frontiers of the Halo Stars where humans and xenos mix in the quest for power and profit. Conquered by Lord Militant Angevin for the Imperium of Man a thousand years ago in the 40th Millennium during what became known as the Angevin Crusade, the Calixis Sector contains many heavily populated and important worlds, though it lies a great distance from the Imperium’s core sectors. The sector’s first Imperial Sector Governor was Drusus, one of Angevin’s most capable generals, a man now revered as a Saint of the Imperial Cult.

This territory represents a vulnerable fraction of the Imperium, far from the millions-strong armies and mighty battlefleets that protect its most ancient and important worlds and defend its war-torn frontiers. The fate of the sector is tainted with disturbing prophecies and haunted by an inexplicable evil. Within its ill-portended bounds there are countless threats to keep the Adepts of the Imperium stretched beyond capacity. It is up to a few extraordinary individuals to save the sector from being consumed by a dark future of corruption and suffering.

The Calixis Sector has many heavily populated and important worlds, but it lies a great distance from the Imperium’s heartland and, like so much of the Imperium of Man, it must ultimately fend for itself. Like all Imperial territories, the Calixis Sector is at risk from the chronic dangers facing humanity: war, mutation, xenos activity, the mark of Chaos, and so on. However, a singular threat lurks somewhere in the Calixis Sector, a mysterious, prophesied doom that has drawn the particular scrutiny of the Inquisition to this group of worlds. This enigmatic threat, the Hereticus Tenebrae, or the Tyrant Star as it is known, is something the forces of the Inquisition most fervently wish to uncover, to comprehend and to destroy, before it is too late for the people of the Calixis Sector—and perhaps all of Mankind.

To trailing, the Calixis Sector is bordered by the hazardous territories of the Fydae Great Cloud and to spinward by the Scarus Sector. Bordering to coreward, its immediate neighbour is the Ixaniad Sector. To rimward lie the contested and unregulated frontiers of the Halo Stars and the infamous Koronus Expanse. The hive world of Scintilla, situated in the Golgenna Reach sub-sector, is the capital of the Calixis Sector. Along with the hellish mining world Sepheris Secundus and the war-torn planet Iocanthos, it forms a triumvirate of worlds essential for the sector’s survival. The most powerful man in the Calixis Sector is officially Sector Governor Marius Hax, who rules in the name of the Adeptus Terra from the Lucid Palace on Scintilla. However, the Calixian Conclave, led by Lord Inquisitor Caidin, is the true ultimate authority in the sector, a clandestine and all-powerful presence behind the visible emblems and figureheads of Imperial power. No one has the power to gainsay the word of the Inquisition. Other important Imperial servants are Lord Inquisitor Zerbe of the Tyrantine Cabal, Cardinal Ignato of the Adeptus Ministorum, Lord Marshal Goreman of the Adeptus Arbites, Senior Astropath Xiao and Canoness Goneril of the Adepta Sororitas. The power of the Imperial Adepta, however, is rivalled by the Great Houses, the noble families and Calixian corporations, which maintain a presence across the sector. Even the minor noble houses, those whose influence is limited to a single world, hold a great deal of power over ordinary citizens.


The Calixis Sector is located in the Segmentum Obscurus, on the northern edge of the known galaxy near the Eye of Terror, and represents a portion of the considerable territories conquered by the Imperial hero Lord Militant Angevin more than a thousand years ago in the 40th Millennium. Its first governor was Drusus, one of Angevin’s most capable generals, a man now revered as a Saint of the Imperial Cult.

The Hereticus Tenebrae (Komus, the Tyrant Star)

The Calixis Sector is beset by many threats but few of them are as obvious as rampaging aliens or widespread
rebellion. Perhaps the most troubling is the prophecy of the Tyrant Star, the horrific harbinger of ruin and desolation, the spectral sun which consumes light, hope and sanity. This prophecy is known as the Hereticus Tenebrae (“the black doctrine” or “the shadow heresy” in High Gothic) by the Inquisitors of the Calixis Sector. Reports of the conflict, destruction and psychic cataclysm that accompany apparitions of the black sun are often suppressed, in case disorder and fear overtake entire worlds.

The baleful Tyrant Star casts an ill light upon the Calixis Sector and nowhere seems immune from its influence. Cults and seditionist groups fester in its underhives and moral corruption gnaws away at the nobility, which holds much of the power on the sector’s scattered worlds. Conflicts brew between the Imperial Adepta and the great noble families who trace their lineage to the times before Lord Militant Angevin’s conquests. Mysteries abound, for the Calixis Sector was quite evidently occupied by more than one long-vanished civilisation in the past. The previous inhabitants of this province of the galaxy have left their indelible traces behind them. Certainly, many Inquisitors of the Calixian Conclave fervently hope that the spectral sun is a legacy of aliens long since gone to dust, for the alternatives have implications that are unspeakable.


The Imperial currency of the Calixis Sector is known as the Throne Gelt or simply the Throne. There are also precious shell tokens or coins of rare metals that are accepted as legal tender on all of the civilized Imperial worlds of the sector. Thrones can also be dispersed in electronic form as payment.
