Blood Trinity

I shall crush my enemies, drive them before me, and hear the lamination of their slaves. All this I do in thy name, oh Great Gods of Blood and Night –Maratan Oath

The Blood Trinity is a Star System of three worlds within the Jericho Reach, currently contested by the Achilus Crusade and the forces of Chaos.

History
Once known as the Mataras Sisters during the day of the lost Jericho Sector, this system was regarded as a jewel of the Imperium. The system supported four verdant and paradise-like Agri-Worlds that served as a breadbasket for the planets of the sector core.

The Age of Shadows heralded a slow descent into blasphemy for this system as, over time, the severed and abandoned Human populations embraced barbarity and the false promises of the Dark Gods to save them from the brutal predations of off-world slavers and the obscene hungers of the alien.

In 920.M37, Mataras IV was subject to the final sanction of Exterminatus. This sanction was carried out by the Deathwatch in order to prevent a parasite-colony of the horrific Hadrus Skin-Weaver xenoform from spreading to neighbouring worlds.

As the populations of the Mataras Sisters slowly succumbed to the worship of Chaos, they strove to excel over each other in savagery and slaughter.

The three surviving worlds of Mataras became known as the Blood Trinity, thriving on violence and fighting unceasingly amongst themselves for the favour for their gods, united only against anything foolish enough to attempt their conquest from without.

The Deathwatch has long suspected that the warlike natives of the Blood Trinity were chosen as a harvesting ground for fresh recruits for certain warbands of the Traitor Legions, with the most vicious among their warriors selected for their ranks.

When the crusade forces first probed into the Cellebos Warzone and stirred the servants of Chaos into response, the god-clans and witch-covens of the Blood Trinity served as a ready base of manpower for the rising powers of damnation. Some of the most vicious shock-troops of the Stigmatus have been drawn from the worlds of the Blood Trinity.

The heretic forces are well aware of the importance of the Blood Trinity to their cause. The system is now heavily patrolled by renegade warships which have, so far, defeated any attempt by crusade forces to forge a beachhead into the system or conduct an effective raid.

Furthermore, the infamous Carnage-class Cruiser Black Grail and its attendant fleet -- believed to currently be in possession of a splinter faction of the Word Bearers Traitor Legion has been repeatedly recorded at orbital anchorage over Matarus III, which provides some measure of the dangers faced by any forces attempting to conquer this system.
