The world of Bheta-Decima slides towards utter ruination. From the lightless void comes a Nemesis Claw of the Night Lords Traitor Legion, twisted warriors motivated by cruelty and selfish desire. Yet as these ancient predators hunt for technological treasures on the ocean-rigs of Bheta-Decima, they are hunted in turn by the Mandrakes of Aelindrach – and it may be that even these sadistic monsters have met their gruesome match.

Scout Squads are comprised of Space Marines in training, not yet fully elevated to the ranks of battle-brothers. Nonetheless, each operative is physically and mentally strong and robust by an order of magnitude over unaugmented Humans. All are competent killers and infiltrators, wreaking havoc behind enemy lines and collecting valuable battlefield intelligence.

Blades of Khaine are elite Asuryani fighting formations assembled for a single purpose: severing a precise strand of fate to ensure that a terrible future for their craftworld or their race as a whole never comes to pass. Striking Scorpions burst from concealment after stalking their prey for hours or waiting in position for days – chainswords whirring and mandiblasters spitting needles of white fire.

The industrial world of Bheta-Decima is collapsing, its surface ravaged by the burning debris and tainted inhabitants of the space hulk Gallowdark. In the ensuing chaos, a Magos Biologis sends an urgent distress call – and is answered by a Scout Squad of the Raven Guard, bound by a centuries-old debt to extract him and his research from a crumbling ocean-rig complex. However, a Blades of Khaine kill team has been dispatched to foil their escape – and the very fate of the Aeldari could depend on it.

The industrial world of Bheta-Decima is aflame, its cities ruined and its polluted seas flooded with warp-taint by the falling debris of the space hulk Gallowdark. The planet's irradiated waters are now riddled with sunken secrets and twisted hazards, and nothing but the crumbling gantries of an oceanic extraction-rig stand between elite kill teams and a watery grave.

Hearthkyn Salvagers are experienced combat-surveyors of the Leagues of Votann, deployed to scout out hazardous locations such as drifting space hulks and rad-blasted killzones in search of wealth and resources. Loaded with advanced equipment for scanning and navigating their dangerous surroundings, these doughty explorers use bursts of intense firepower to eliminate anyone obstructing their search.

Beastmen are an abhuman subspecies, condemned across the Imperium as unclean mutants. Embittered by their persecution, many Beastmen turn to the Ruinous Powers, congregating on the outskirts of civilisation in savage herds dominated by Fellgor Ravagers. These brutal Beastmen are veterans of countless raids, who prove their strength and devotion to the Dark Gods through braying war cries, swift slaughter, and violent sacrifices.

Archons are the rulers of the Dark City's Kabals, callous Drukhari schemers driven by boundless avarice. When these cartel-masters require precision and certainty, they assemble their Hand – an elite team of Kabalite experts, chosen for their terrifying skills in everything from poison to bladework. Hands of the Archon accomplish their employer's dark whims without fail – all while jockeying for influence and prestige in the courts of Commorragh.

After thousands of years adrift in the warp, the space hulk Gallowdark has emerged into realspace. A colossal, moon-sized derelict inhabited by mutants, aliens, and things known only by the screams of their victims, the Gallowdark's shadowy depths hold prizes beyond comprehension – ancient treasures, arcane weapons, and secrets forgotten to the galaxy. Kill teams of deadly operatives stalk each other through winding corridors and decaying machinery, conducting daring raids, assassinations, sabotage, and epic last stands that engulf the Gallowdark in a shadow war.

Commanders of elite kill teams know that victory is often a matter of securing the proper resources and ensuring their operatives have the tools they need to get the job done. Given the critical nature of their missions, kill teams often find themselves equipped with all manner of useful tools, from measuring devices to portable barricades.

The Adeptus Arbites enforce the Imperium's laws without exception or mercy. Exaction Squads are formed of only the most experienced Arbitrators, called into service to hunt down dangerous transgressors for interrogation and punishment, no matter where they hide. They do not hesitate to crush any who stand in their way, ruthlessly bludgeoning or cutting them down in blazes of firepower, never halting until their target is in custody.

Rogue Traders are merchants of death and explorers of the unknown, each granted powers and responsibilities beyond measure by their heirloom Warrant of Trade. Gathering hard-bitten companies of crew, mercenaries, and retainers, these bold privateers venture into hazardous warzones and uncharted space in search of profit. Elucia Vhane stands proud amongst these luminaries. The scion of a noble mercantile dynasty, she seeks to eclipse the rich history of her ancestors – or die trying.
