When and where
As previously stated the campaign will be placed in Calixis Sector, the official DH setting. This gives a variety of ready background info that can easily be integrated with my own campaign plans...less work for me, more fun for you...
Calixis Sector is located on the fringes of Segmentum Obscurus, with Scarus Sector (setting for the Eisenhorn/Ravenor books) and Finial Sector as its Spinward (galactic right) neighbors. To Rimward Calixis Sector (and Scarus too!) is bordered by the dark and cold expanses of the Halo Stars, a dangerous and ill-explored region of old stars and great voids. Coreward lies the old and dangerous space of the Ixanaid and Finial sectors, with the Eye of Terror looming ominously beyond them, blocking a direct path from Calixis to Segmentum Solar. Trailing (galactic left) lies the great nebula called the Fydae Great Cloud – and beyond that Segmentum Pacificus. Calixis is by all standards a remote and unimportant place.
Interrogator Xerza maintains Tancred's operational headquarters in middle levels of Hive Tarsus, far removed from the prying eyes of the nobles huddling in the lower dark, but still well protected by the hive's topmost layers. From here Tancred's Cadre has easy access to the pulsing heart of Scintilla – the great transshipment ports of Tarsus and the geosynchronous spaceport in orbit above it. From this heart Acolytes and information flow along the warp-veins of Calixis to touch upon the most remote of planets.
The year is 996.M41 and the citizens of the Imperium of Man are bracing themselves in dread anticipation for what horrors the new millennium will throw at them...whatever it is it will not be pleasant, for in the dark and distant future there is only war. A war that is fought across a million nameless battlefields, some of them hidden in the very heart of Calixis sector – enter the Acolytes...
