- "All mortal creatures must die. Only then can the galaxy be reborn anew."
- — Anonymous Purge Chaos Space Marine
The Purge is a Chaos Space Marine warband dedicated to the Chaos God Nurgle, the Plague Lord. They despise life in all its forms and have waged pitiless war against xenos and Mankind alike since the late 36th Millennium, consumed by their self-imposed quest to exterminate all living creatures. Having seen first hand the dread threat of Chaos, they believe that the civilisations of the galaxy are hopelessly corrupt and that the only salvation lies in the sterility of death. The Purge know that they are too few in number to achieve this goal on their own, and hence they pray nightly to the God of Plagues for a mighty pandemic that will destroy every sentient being.
Though The Purge see their purpose as pure, those who witness the pestilence and starvation they leave in their wake are under no illusion as to their true allegiance. When The Purge attack a world, famine, pestilence and death soon follow. They are infamous for their conduct of genocidal campaigns and the indiscriminate use of chemical weapons on civilian and military targets alike. They recently played a major role in defending the other Forces of Chaos during the Siege of Vraks by the Imperial Guard. Their current location is unknown.
- Antecanis Massacre (165.M37) - The Purge is known to have participated in the Antecanis Massacre in 165.M37 alongside the Black Legion and other Chaos Space Marine warbands.
- Hell's Last Duke (931.M38) - The Space Hulk Hell's Last Duke ploughs into the surface of Bereguel Tertia, causing an extinction-level event. Many of the world's most valuable dignitaries save themselves by taking to underground bunkers as the massive nightmare bulk of the Space Hulk burns through the atmosphere. Though they believe themselves to have escaped the worst of the disaster, the dignitaries soon learn otherwise when the Renegade Space Marines of The Purge emerge from the heart of the hulk and begin to hunt them down. The Space Marines of the Fire Lords Chapter receive the distress call and divert their Crusade to make planetfall upon Bereguel. Their Centurion Siegebreaker Cohorts bore holes into the rockcrete of the hulk, leading a massed assault right into the dark chamber that serves as its bridge. A close-quarters battle breaks out, and though the Fire Lords lose several of their Centurions in the process, the grisly death of the Chaos Space Marine Lord Doluthec ensures the warband is left leaderless and eventually defeated.
- Siege of Vraks (813-830.M41) - The Purge were one of the Chaos Space Marine warbands that answered the call of the Chaos Lord Arkos the Faithless of the Alpha Legion to support the defence of the Forces of Chaos entrenched on the Armoury World of Vraks from the assault of the Imperium of Man. After the Siege of Vraks ended with the fall of that benighted world to Imperial forces in a horrifically costly military campaign in 830.M41, The Purge fled off-world.
- The Corruption of Bellru & Fealty II (884.M40) - Possessed Chaos Space Marines guide a fleet of The Purge's rusted plague ships through a squall of unnavigable Warp Storms to seed the Agri-Worlds of Bellru and Fealty II with vile diseases. Given their small numbers, The Purge spread an impressive amount of death and destruction. On each world, they send their ships plunging down into the oceans and onto land. The broken hulls empty out deadly spores into the atmosphere, infecting billions of inhabitants.
- Vaxhallian Genocides (926.M41) - In the year 926.M41, The Purge sought to vent their hatred of all living things, and chose the verdant Imperial world of Vaxhallia as their victim. The planet's surface was soon riddled with consumptive disease and crippling famine. Over the course of a single solar month, The Purge engineered the destruction of no fewer than 14 billion Imperial citizens, laying claim to the plague-ridden world.
- Invasion of Medusa (Unknown Date.M42) - Alongside warbands of The Cleaved, The Purge and several other Nurglite Renegade forces, Typhus leads the Death Guard's 1st Plague Company in a shocking raid against the Iron Hands' Chapter Planet, Medusa. The Iron Hands' clans drive off their attackers, but not before terrible damage is done, leaving regions of the planet as cursed quarantine zones.
Notable Members of The Purge
- Doluthec (KIA) - Doluthec was a Chaos Lord of The Purge warband. In 931.M38, he assaulted the world of Bereguel Tertia with the Space Hulk designated Hell's Last Duke. Though many of the world's most important dignitaries saved themselves by taking shelter underground, believing they had escaped the worst of the assault, the dignitaries soon learned otherwise when the Renegade Space Marines of The Purge emerged from the heart of the Hulk and began to hunt them down. The Space Marines of the Fire Lords Chapter diverted their forces from a nearby crusade front to the planet and confronted the Chaos Renegades with their Centurions. This battle resulted in the grisly death of Doluthec, and ensured the warband was left leaderless. It was eventually defeated by the Loyalists.
The Purge paints the helmet, shoulder plates and lower leg plates of its Power Armour grey-green and the hands and torsos black.
The warband's badge is three black flies facing each other set 120 degrees apart on a grey-green background, which mirrors the standard sigil often called the Mark of Nurgle.
