The Slaugth are a xenos race, vaguely humanoid in shape, covered in hundreds of half-melded maggot-like worms. Covered in viscous mucus, they are impervious to all but the most extreme injury.
The Slaugth are believed to be impossibly ancient, likely native to the Calixis Sector long before the arrival of Mankind. Much of their known activity takes place around the region of the Hazeroth Abyss that consists of cursed space and dead stars. Their true homeworld is, however, unknown and may not be located within the Abyss. Their origins are largely unknown to the Imperium though Rogue Traders and xeno-savants believe that any empire that they hold lies far out the Trailing Halo Stars. The circumstances of the first contact between mankind and the Slaugth is unknown, though some sources claim that they have been encountered on the edge of Imperial space as far back as the Age of Strife. The abundance of humans in the galaxy has led to them becoming the favoured prey of the Slaugth. Despite this, they seem content to use infiltration and human agents to bring about their incomprehensible plans.
Many of the encounters with these xenos follow the same pattern, with black, tenebrous vessels entering into Imperial space, where they wreak havoc on isolated outposts or shipping lines. The Slaugth’s victims are either left behind as mutilated bodies or disappear altogether. In other encounters, the Slaugth give their vile technologies to renegade humans in exchange for slaves. Those Imperial worlds that border the Hazeroth Abyss often tell the stories describing the Slaugth as the “worms that walk”, a nightmare that emerges from the depths of the Abyss to kill the living and feast on the dead. Ultimately, however, the upper echelons of the Imperium dismiss them as little more than a myth.
