The Chaos-corrupted troopers of the Moebian 6th Regiment, now a Traitoris Militarum regiment dedicated to the service of the Chaos God Nurgle whose guardsmen are nicknamed "Scabs" by Loyalist forces.
The Moebian 6th Regiment is a Traitoris Militarum regiment, formerly of the Moebian Regiments of the Astra Militarum, that has turned Traitor to the Imperium and embraced the worship and cause of Nurgle, the Chaos God of disease and despair. Imperial forces now often refer to the Moebian 6th's troops as "Scabs."

Like most of the Moebian Regiments, the Moebian 6th was raised on the capital world of the Moebian Domain, the Hive World of Atoma Prime, and before its corruption long gave excellent service to the Emperor in defending the domain from the forces of Chaos and xenos threats in what was known to the people of the domain as the Fringe War.
The Moebian 6th was heralded for solar decades as the toughest and most decorated regiment among its fellows. The Moebian 6th was celebrated by the citizens of Atoma Prime as their greatest guardians and heroes before their fall to Chaos.
Since its corruption, the Moebian 6th has determined that it will bring the truth of Nurgle to all the people of Atoma Prime, and will slay anyone who stands in their way of freeing their people from the stagnant rubrics of the Imperium. They are aiding the Chaos Cult known as the Admonition in spreading their beliefs through Hive Tertium, the primary hive city of Atoma Prime.
Like their allies among the Dregs of the Admonition, the Scabs' primary objective seems to be summoning Nurgle's Daemons into realspace by weakening the veil between the Warp and the mortal universe through the unleashing of death on a truly massive scale across Tertium with the Plague Lord's supernatural diseases. All across Tertium the Heretics have written in the Dark Tongue portions of a Daemonic summoning ritual that claims, "Nurgle shall be called with Death."
The cultists' and Traitor guardsmen's willing embrace of Nurgle seems to have its root, like many Chaos Cults active in the Imperium, in the rage and hatred the Emperor's subjects so often feel towards the difficult circumstances of their lives. This is the hatred the cultists and the soldiers of the Moebian 6th have for the corrupt ruling-class of Atoma Prime and the Moebian Domain; the endless cabal of greedy nobles squabbling in pointless struggles for power while the hive city and the greater Moebian Domain rots and crumbles around them, its people living lives oppressed by tyranny and economic deprivation.
This rage is intensified even further for the guardsmen of the Moebian 6th who fought in the Fringe War and were badly traumatised by what they faced on the frontlines and by their anger at being sent out to face such horrors by the nobility of the Moebian Domain. As such, embracing Nurgle can be seen by the guardsmen as obtaining a form of "freedom" for themselves and the people of Hive Tertium from the oppression and poverty of life in the Imperium, however insane and twisted such freedom may ultimately be.
Unlike their allies in the Admonition who are known as "Dregs" among Imperial forces, the Scabs possess heavier armour like Flak and Carapace Armour, superior warfighting skills and more advanced weaponry drawn from their Astra Militarium service.
In response to the dire threat represented by the Moebian 6th's activities, the Ordo Hereticus of the Inquisition under the command of Inquisitor Grendyl deployed its requisitioned military forces and Acolytes into Hive Tertium in a race against time to save the hive city before it can grow into a cancer that could consume the entire world, or even eventually threaten the entire Moebius Domain.
History[]

The semi-autonomous Moebian Domain is highly loyal to the Emperor and the domain itself is considered a significant tract of Imperial space. The Moebian Domain is a fiefdom comprised of several strategically important worlds in the Segmentum Solar, loyal to Terra and ruled over by the Lord Moebian Constant Margrave of the domain's capital Hive World of Atoma Prime, who serves essentially as its planetary governor as well as the sector lord.

The domain can be considered a province or a self-governing state of the Imperium. It pays its tithes and taxes to Terra, it obeys Imperial law, and its worlds manufacture vast quantities of strategically important goods for the Imperium. It is thus highly important to the Imperium and must be defended from assault by the Emperor's foes, whether they be within or without.

Unfortunately, the Moebius Domain borders several disputed territories of Wilderness Space called the "Fringe" that contain multiple xenos and Chaos threats. The Adeptus Administratum ensures that for the average citizens of the domain the nature of that threat remains a mystery. It is just called the "Darktide," a shadowy threat that must be kept at bay if the people of the domain are to remain in the God-Emperor's light.

A Scab Captain is a former company commander of the Moebian 6th, now heavily mutated and armed with a Plasma Gun and sometimes a Power Maul, as well as protected by a personal void shield emitter.
It is to protect the domain from the Darktide that the Moebian Regiments of the Astra Militarum are raised, mostly from the teeming populace of Atoma Prime but also from several of the other worlds of the region. The Moebian Regiments have for centuries been fighting an on-going conflict known as the Fringe War against the Darktide.
The young people recruited to these regiments have no idea where they are being sent, or what they will face. They are as ignorant of the "Darktide" as any other regular citizen, for they were all once citizens themselves. They quickly learn otherwise.
The galaxy is not a friendly or safe place. There are brutal horrors out there -- xenos species, alien predators, and worse -- who want nothing more than to extinguish the fluttering flame of Human civilisation. Out on the Death Worlds of the Fringe, the guardsmen of the Moebian Regiments, called "lasmen," are thrown into the meatgrinder and come face-to-face with unimaginable danger. In time, their world-view changes. They learn the nature of the Darktide and fight it tooth and nail.
Sometimes, they learn too much.
Long tours result in trauma, both physical and psychological. Some lasmen are broken by the experience. Some are made bitter and resentful that the gruelling combat they experience is generally unrecognised back home, because the Administratum tends to keep all details of the ongoing conflict quiet so as not to generate public alarm. There might be a few news broadcasts about "great victories," but the rest of the turmoil is screened by propaganda.
Some troopers, of course, serve brilliantly and bravely, and remain loyal despite everything they experience. But others fall prey to the insidious touch of the Darktide. They encounter the malevolent effect of the Warp, and it changes them. They become -- literally, in some cases -- the very thing they are fighting against.
The Moebian 6th were seduced by the creed of the Darktide and the lies of the Chaos God Nurgle, and they now seek not simply to kill and exact vengeance for what they endured in the battles of the Fringe War, but to share the dark "truth" they have uncovered. They truly believe they have seen the light offered by Chaos, and that the dark ways they have discovered are far better and more liberating for Humanity than the stagnant rubrics of the Imperium. They now seek to share that truth with every living soul on Atoma Prime and they will slay without remorse any who seek to stop them.
In the Era Indomitus, the Chaos Cult called the Admonition infested the hive city of Hive Tertium on Atoma Prime. When they unleashed the Walking Pox upon the hive and a swarm of Poxwalkers began to assault the lower reaches of Hive Tertium, the Moebian 6th was redirected from frontline deployment to assist in combating the Nurglish corruption. Instead, the corrupted regiment turned on the people it had sworn to protect and began to support the uprising.
Regimental Organisation[]
The Moebian 6th, like all of the Moebian Regiments, refers to its guardsmen as "lasmen." The regiment was originally an elite Imperial force that possesses many different units and specialties beyond what are usually available to a more standard Astra Militarum regiment.
They maintain units of fierce melee troops who excel at close range and hand-to-hand combat. They have Storm Troopers, snipers, flame-troopers, demolition units, and Heavy Weapons Squads. They possess all the needed specialties an armed unit needs if it wants to take down an Imperial world.
