Dark Heresy - The Gorgon Conspiracy
Komus, the Tyrant Star
The so-called Tyrant Star resists easy interpretation but certain key facts are evident.
Komus is described in a doom-laden vision which speaks in apocalyptic terms of a “darkness” that will engulf the worlds of man and ultimately devour human civilisation. The engulfing darkness will be preceded by signs and portents, so-called herald events, that will gradually transmute human minds and make them ready to embrace the darkness. Many believe this to be an obvious allusion to a rising of Chaos and the warp, though this explanation is far from universally agreed. There are many considerable threats in the galaxy. The prophecy could as much apply to the Tyranids (scholars note a repeated use of the word “devour” in the prophecy text) or the Eldar as to the warp. However, given the warp’s manifest ability to uncreate and mutate reality, much weight is given to this idea by the Tyrantian Conclave. The actual text of the prophecy is secured in the archives of the Bastion Serpentis, and Lord Inquisitor Zerbe only allows a very favoured few to examine the complete transcript.
From time to time—no specific interval period has been identified—a monstrous “black sun” matching the prophetic descriptions of the Hereticus Tenebrae has mysteriously appeared in various locations throughout the sector.
No two appearances have been quite the same but the pattern of visitation is usually this: with little warning, a ghostly star apparently emitting black flames and esoteric, unknown forms of radiation, spontaneously materialises in a planetary system, shines malevolently for a few days, and then, just as mysteriously, vanishes without trace. The visitation is accompanied by psychic disturbance, geological upheaval and sociological problems on inhabited worlds, including mass rioting and unrest.
Whatever the truth, the phenomenon is a fact. It has manifested eighteen times in the Calixis Sector during the last century (8th Century of the 41st Millennium). Every single visitation has caused public unrest and geological instability. Where the Tyrant Star appears, earthquakes and volcanic upsurges follow. A world will experience a violent period of upset and political revolution prior to its appearance. Many more psykers than usual will be born or become active. Mutation will occur more often. These things will usually take place in the two or three months leading up to a manifestation. Signs and portents will be widespread: these generally are a matter of birthmarks, odd runic sigils appearing upon walls without explanation and the rise of fanatical religious cults. Some sources also describe premonitory half-sightings, fleeting glimpses of the black-flamed sun in mirrors, pools, puddles or even on the surface of wine or water in drinking vessels.
