===The Grendel===
The Grendel are a minor species of xenos once inhabiting a tiny band of worlds on the far fringe of the Segmentum Ultima. In the late 39th millennium they took to raiding nearby Imperial worlds; stealing weapons, crops and taking imperial citizens to serve as slaves on their bastion homeworlds. Local naval patrols were confounded in their efforts to track or pursue these raiding fleets due to a local phenomena: a dense black nebula which obfuscates all attempts to scan it. The Grendel would skim the surface of this nebula, obscuring their ships from pursuit, only to emerge and strike another world once the navy had retreated. 

An individual Grendel stands at nearly seven foot, has natural claws that can rend into ceramite and is capable of great feats of natural strength. They wield unusual weapons which combine traditional firearms with cybernetic and biological components, and each firearm seems to have a different ammunition profile: from a standard metal slug, biological components such as teeth, or even an organic cocktail of nano-particles which render the victim hallucinogenic, disorientated or even diseased. This has a devastating effect on enemy forces, making it impossible for combat medics to predict just what kind of injuries they'll see after a skirmish.
