Pale Stars - Convergence: Even as Lorn Orpheus was readying his flotilla at the Luna shipyards, other forces were converging upon the Pale Stars. One was an alliance of Astartes who had, each for their own very different reasons, renounced or severed their ties to their sire-Legion and obscured their heraldry; the other served an equally shadowed cause, albeit one that most others associated with the Traitors -- the Alpha Legion. Which faction came to the Pale Stars first is one detail amongst many now lost to history and none can tell if their appearances were linked or simply coincidental -- most likely the tides of the unquiet Warp simply stranded both there at the same moment in time.The first group would come to be named the "Dark Brotherhood" by the peoples of the Pale Stars and later other regions, though none can tell if the group itself ever acknowledged or used this name. Very little is known for certain about the Dark Brotherhood, and even less of the circumstances of its formation, but it is clear that this band of what would become known as "Blackshields" had formed around a warrior known as the "Nemean Reaver," or simply "the Nemean," a title likely referring to the impenetrable Artificer-wrought Power Armour he was said to wear in battle or to suggestions that he was preternaturally strong and impossible to slay. Of the origins of this war leader very little is certain, though some accounts claim he was a Terran scion of the I Legion and a veteran of the Third Rangdan Xenocide, a notion at least partially borne out by elements of the sparse personal heraldry he wore and by the terrible scars that marred his features. The Nemean was a taciturn and brooding warrior and leader, but by 008.M31, he had bound the disparate warriors of the Dark Brotherhood into a coherent whole and moved quickly to establish a haven, a sovereign domain deep in the void beyond the spiral arms where he and his brethren might forge their own destiny in a galaxy fallen to insanity.It was at the trinary star system known as the Eridayn Cataract that the Dark Brotherhood found refuge. A dense shroud of asteroids circled the system's three stellar bodies, concealing secrets and hazards that only the most accomplished of void masters could hope to navigate. The Dark Brotherhood were possessed of such individuals, their small fleet of light but fast and agile vessels crewed by a motley assortment of Voidborn and captained by an Astartes who had seen service in some of the most arduous campaigns of the Great Crusade. Having established a secure base of operations deep within the asteroids, the Dark Brotherhood laid claim to the entire stellar realm and the boundless natural resources that orbited its three stars. Within only solar months the Dark Brotherhood was aggressively defending its interests, ranging the surrounding Warp routes to clear them of any foe that might contest their mastery, from human and xenos void pirates to patrol vessels sent out by the small Imperialis Armada squadron stationed at Phargos Rex. In late 007.M31, the Brotherhood launched a sudden and overwhelming assault upon the nearby system of 771 / 51-6. There they brutally purged the human-xenos hybrid pirate clans that had preyed upon the region's outlying worlds since the time of Old Night, the Nemean executing their master by his own hand as an indisputable message to all of that abominable strain. The name of the Brotherhood's brooding reaver lord was soon known across a dozen and more systems, and whispers of his formative empire spread still further. Soon after this event came word of the arrival in the region of a Traitor Legiones Astartes strike force of the Alpha Legion, commanded by Strike Master Ijax, a bloody-handed veteran of the Drop Site Massacre at Istvaan V.Strike Master Ijax had come to the Pale Stars as an emissary of the Traitor cause, his mission to ensure that the region's planetary rulers declared for the Warmaster. Instead of presenting himself directly at Phargos Rex, Ijax divided his command and despatched lieutenants as envoys across the region, each going before a planetary lord to deliver Horus' missive. Each recipient was informed that their peers were being made the very same offer at the very same moment. In so doing, each planetary ruler was compelled to reach their own decision without recourse to their fellows, the Alpha Legion envoy standing before them feeding their darkest fears about what the Warmaster's fleets might have in mind for their world while simultaneously appealing to their most venal desires with insinuations of the favour they might earn upon declaring for Horus and the Traitor cause. The presence of the Dark Brotherhood, however, forestalled immediate acquiescence. Upon learning of the Nemean and his pocket empire, Strike Master Ijax saw at once the necessity of neutralising this rival faction and an opportunity to seal the compact with the planetary rulers. If the Planetary Governors would commit their own forces to his command in the joint endeavour of ridding the Pale Stars of the Dark Brotherhood, then the Warmaster would surely bless each ruling house with his unconstrained largesse. The rulers saw no choice but to comply.
