List of Chaos Space Marine Warbands - S: NameOriginFoundingSummaryThe SanctifiedWord BearersUnknownThe Sanctified are a warband of Chaos Space Marines and a splinter faction of the Word Bearers Traitor Legion, that broke away from their parent Legion at the end of the Horus Heresy. They are followers of the Blood God Khorne, which precipitated their split from the Word Bearers, who preferred to worship the Chaos Gods as a whole. It has been observed that The Sanctified have the innate ability to locate newly founded Imperial colonies and Explorator fleets in the vast tracts of unknown areas of space, preying upon these targets for the last ten millennia.Sanctors of TerraunknownUnknownA formerly Loyalist Space Marine Chapter of unknown origin and Founding, they were corrupted after entering the Eye of Terror as a part of the Imperial Abyssal Crusade in 321.M37. When they eventually reemerged, they had become a Heretic Astartes warband known as the The Blighted Claw.Sanguine SonsUnknownUnknownThe Sanguine Sons was a warband of Chaos Space Marines of unknown origin or Founding. Little else is known about this particular warband in official Imperial records. Recently, they took part in the Cholercaust Blood Crusade in the 41st Millennium.Savage SwordsUnknownUnknownThe Savage Swords are a formerly Loyalist Space Marine Chapter that turned renegade in 721.M39. Their Chapter Master led them down a path of retribution and blood when he mistakenly believed the Planetary Governor of Hyboras had stolen the Chapter's ancient relic blade. His Chapter committed a series of atrocities on the Feral World, but only when the Chapter Master sat upon the Governor's gore-stained throne did he realise the extent of his folly, though by then it was too late. When the Black Legion arrived, the Savage Swords had already fallen to the worship of the Blood God, Khorne, and joined Abaddon eagerly.Screaming SkullsUnknownUnknownThe Screaming Skulls were a formerly Loyalist Space Marine Chapter known as the Calix Chapter, which were created during an unknown Founding and of uncertain origin. During some unknown point in history, the Calix Chapter broke their oaths of fealty to the Imperium of Man following the so-called Massacre of Ravenscar and willingly followed the Ruinous Powers into damnation. Following their actions, they were declared Excommunicate Traitoris by the High Lords of Terra. After their fall to Chaos they became the Renegade warband known as the Screaming Skulls. Following their involvement in the Constantinus Iconoclasm, their fate remains unknown.The ScourgedSeekers of TruthUnknownThe Scourged are a warband of Chaos Space Marines dedicated to the service of Tzeentch, the Changer of Ways. The Scourged are believed by some Imperial scholars to be a possible splinter warband of the Thousand Sons Traitor Legion but the truth is somewhat darker. The Scourged once served the Inquisition as the formerly Loyalist Chapter of Space Marines known as the Seekers of Truth. Chapter Master Gallus Herodicus was an honourable man and rankled whenever ordered to execute innocents. The injustice was draining the Seekers' morale, and in the night, Herodicus prayed to the God-Emperor for a way to know when a man was lying. Unfortunately, the Chaos God Tzeentch was listening and granted his prayer. From that moment, Herodicus and his men could hear every lie spoken by the mouths of Mankind. The Chapter went rogue within days. Though they could have saved the Imperium from heresy once and for all, the constant stream of falsehood in their heads has driven them insane and turned them against the service of what they now view as the Emperor's irredeemably corrupt Imperium.The Sectai ProsperineThousand SonsUnknownThe Sectai Prosperine, is a thrallband of Chaos Space Marines dedicated to the Chaos God Tzeentch that was originally formed by members of various minor sects of the Thousand Sons Traitor Legion that banded together in order to reap the benefits of their combined knowledge and power.Seekers of TruthUnknownUnknownThe Seekers of Truth were a formerly Loyalist Space Marine Chapter of unknown origin or Founding. Chapter Master Gallus Herodicus was an honourable man and rankled whenever ordered to execute innocents. The injustice was draining the Seekers' morale, and in the night, Herodicus prayed to the God-Emperor for a way to know when a man was lying. Unfortunately, the Chaos God Tzeentch was listening and granted his prayer. From that moment, Herodicus and his men could hear every lie spoken by the mouths of Mankind. The Chapter went rogue within days, becoming the Renegade Warband known as The Scourged. Though they could have saved the Imperium from heresy once and for all, the constant stream of falsehood in their heads has driven them insane and turned them against the service of what they now view as the Emperor's irredeemably corrupt Imperium.SensoriansEmperor's ChildrenUnknownThe Sensorians are a warband of Chaos Space Marines who serve the Prince of Pleasure, Slaanesh.SentinelsunknownUnknownA formerly Loyalist Space Marine Chapter of unknown origin and Founding, they were corrupted after entering the Eye of Terror as a part of the Imperial Abyssal Crusade in 321.M37. When they eventually reemerged, they had become a Heretic Astartes warband known as the Corpus Brethren.Serpents of LightUnknownUnknownThe Serpents of Light were once a Loyalist Chapter of Space Marines of unknown origin and Founding. They were corrupted after entering the Eye of Terror in 321.M37 as part of the Imperial Abyssal Crusade. It is unknown what they endured during their sojourn into the Eye, but by the time they made their way back into realspace, they had become the warband of Chaos Space Marines known as the Predator Legion.The Shadowed OnesAlpha LegionUnknownThe Shadowed Ones are a large Renegade Warband comprised of Chaos Space Marines and Chaos Cultists drawn from the Alpha Legion. Following the tragic events of the Horus Heresy, during the unending bloodshed of the Great Scouring, the Traitor Chaos Warlord Dynat Mal, known as "Crowbane" for his ambush and slaughter of Raven Guard forces during the Battle of Lyx, fled to the Mandragoran Stars and gathered to him a coterie of Renegades, diabolists and Traitors thousands strong. Imperial forces sent in pursuit were repeatedly out-manoeuvred and cut apart piecemeal as Dynat's forces, now known as "The Shadowed Ones", employed guerrilla tactics and dark forces to extend their mastery over the region. After the vital Imperial outpost station at the world of Amarah, in what is now the Orpheus Sector of the Segmentum Tempestus, was attacked and destroyed, its entire population slaughtered and stockpiles plundered, any Imperial claim to the region is effectively severed. This sundered realm, caught beyond the light of the Imperium at the edges of the Veiled Region, became known as the Dark Marches and is benighted by ignorance and discord, and is shrouded from human sight.Shatter CorpsIron WarriorsUnknownThe Shatter Corps is an Iron Warriors Chaos Space Marine warband active in the Warp rift known as the Screaming Vortex. They are led by the Warsmith Madrydon Drados. Under Drados' command, the Shatter Corps seeks to destroy the Imperium's many fortifications and fortresses throughout the sectors that lay near the Screaming Vortex. By doing so, Drados believes the Imperium will soon topple beneath its own weight and leave itself open to be attacked by the Forces of Chaos.Shattered TowerIron WarriorsUnknownThe Shattered Tower was a warband of Chaos Space Marines drawn from the Iron Warriors Traitor Legion. It is believed that they were utterly destroyed by their gene-brothers during the Dispute of Iron.Shining BladesUnknownUnknownThe Shining Blades were a former Loyalist Space Marine Chapter which possessed an unshakeable faith in its own abilities. They were victorious in battle so many times that they convinced themselves they could not fail, leading to the Berillia Massacres of 498.M34. Their overweening pride and willful delusion caused them to attack, in a frenzy of indignation, any who questioned their magnificence. Renaming themselves the Flawless Host, they have scarred the Imperium ever since as hedonistic servants of Slaanesh, still believing themselves to be pinnacles of perfection.The ShrivenBrazen DrakesUnknownThe Shriven are a warband of Chaos Space Marines that are now a part of the Black Legion. They were once a Loyalist Chapter of Space Marines of unknown origin and Founding known as the Brazen Drakes. The Brazen Drakes are the first known Chapter whose Primaris Space Marine reinforcements also turned against the Imperium and went Renegade.Shrouded HandAlpha LegionUnknownThe Shrouded Hand is a warband of Chaos Space Marine Chosen drawn from the Alpha Legion Traitor Legion. Other than their intervention on the world of Zharastia Jensen during the so-called War of Hidden Lairs, little else is known about this warband in Imperial records.SigilitesUnknownUnknownThe Sigilites were once a Loyalist Chapter of Space Marines of unknown origin and Founding. They were corrupted after entering the Eye of Terror in 321.M37 as part of the Imperial Abyssal Crusade. It is unknown what they endured during their sojourn into the Eye, but by the time they made their way back into realspace, they had become the warband of Chaos Space Marines known as the Malefactors.Silver GuardsUnknownUnknownThe Silver Guards are a Renegade Chapter of Chaos Space Marines who turned to the service of the Ruinous Powers alongside the Sons of Vengeance during the Obscuran Uprisings which ravaged the Segmentum Obscurus during the 34th Millennium.Silver SonsThousand SonsUnknownThe Silver Sons are a Chaos Space Marine warband that was formed by members of the Thousand Sons Traitor Legion who were exiled by their Primarch Magnus the Red for aiding in the disastrous sorcerous ritual called the Rubric of Ahriman. They are known to line their Power Armour with priceless metals that have been extracted from celestial objects. They believe this makes them one with the stars by bestowing upon them a measure of the cosmos' natural power.Six-CursedThousand SonsUnknownThe Six-Cursed is a thrallband of the Thousand Sons Traitor Legion commanded by the Sorcerer Mordant Hex.Skull Takers of Hans Kho'renWorld EatersUnknownThe Skull Takers of Hans Kho'ren are a warband of Chaos Space Marines drawn from the World Eaters Traitor Legion that follow the infamous Chaos Lord Hans Kho'ren. They are notable for having taken part in the First War for Armageddon.SkulltakersBerserkers of KharadonUnknownThe Skulltakers are an infamous Khornate warband of Chaos Space Marines that follow the infamous Chaos Lord Zhufor. Formerly known as the Berserkers of Kharadon, this once-Loyalist Space Marine Chapter disappeared from the Imperium of Man from 153.M34 to 184.M39. During these five millennia the Berserkers of Kharadon turned to Chaos, and the bloody worship of Khorne, rechristening themselves the Skulltakers. With the Styx-class Heavy Cruiser Blood Dawn leading their fleet as its flagship, the Skulltakers have raided and plundered across the galaxy, killing indiscriminately and gathering skulls in the name of Khorne.Skyrar's Dark WolvesSpace Wolves (Unconfirmed)UnknownSkyrar's Dark Wolves are a warband of Chaos Space Marines that might be a possible splinter faction of formerly Loyalist Space Wolves Space Marines who turned to the Chaos Gods. They were first sighted by Imperial forces operating in the Fenris Sector.SlaughterkinUnknownUnknownThe Slaughterkin were a warband of Chaos Space Marines dedicated to the service of the Blood God Khorne led by the Chaos Lord Mahaur the Harvester who carried out the Scourging of Kerrack in 932.M41.Smogrot BrotherhoodDeath GuardFirst FoundingThe Smogrot Brotherhood is a warband or vectorium of the Death Guard Traitor Legion's 5th Plague Company. The enduring popularity of Foetid Bloat-drones with the Traitor Legion's Death Guard Lords ensures that they are ferried in great numbers to the war zones in which the Death Guard fight, and deployed in swarms that darken the skies. This is especially true in the vectoriums of the 5th Plague Company, with warbands such as the Sons of the Maggot, the Suppurant Sting, and the Smogrot Brotherhood fielding great numbers of Foetid Bloat-drones in varying pack strengths and configurations.Sons of the CyclopsBlack LegionUnknownThe Sons of the Cyclops are a special formation of Chaos Space Marines found within the Black Legion who are wholly dedicated to the service of Tzeentch. The Sons of the Cyclops are the smallest of the formations dedicated to a single Chaos God within the Black Legion.Sons of DamnationWord BearersUnknownThe Sons of Damnation are a warband of Chaos Terminators that consist of a single squad drawn from the ranks of the Word Bearers Traitor Legion.Sons of GideonUnknownUnknownThe Sons of Gideon were a former Loyalist Space Marine Chapter of unknown Founding and origin. The Crimson Fists Chapter was called upon by the High Lords of Terra to exterminate the Sons of Gideon because they had been declared Excommunicate Traitoris and had embraced madness and heresy.Sons of HateUnknownUnknownThe Sons of Hate are a Renegade warband of Chaos Space Marines of unknown origin and Founding. They are known to have laid claim to the highly contested world of Brigannion Four, which lies just outside the Eye of Terror, close to the stable warp route known as the Cadian Gate. This world is an unimaginably vast fortress of corrupt magic and machine, made all the more impregnable by its current ruler, Manneus Drath of the Iron Warriors Traitor Legion. The Sons of Hate constantly vie with some of the original Traitor Legions who have also laid claim to this contested world, including the Night Lords, Death Guard and the Black Legion, as well as another warband, the Brotherhood of Blood.Sons of MaliceUnknownUnknownThe Sons of Malice are a Renegade Chapter of Chaos Space Marines who turned Renegade some time prior to the start of the 13th Black Crusade in 999.M41. The Sons of Malice were originally founded to watch over the sectors of Imperial space surrounding the Eye of Terror as one of the 20 Chapters of the Astartes Praeses. Events leading to the Chapter's excommunication began following the successful end of the Cilix 225 Campaign against heretics who had threatened to depressurise three underwater hive cities on that world, and ultimately led the Chapter to declare itself to be both enemies of the Imperium of Man and the Forces of Chaos even as it took up service with a Chaos God, the Renegade God Malal, also called Malice, the Hierarch of Anarchy and Terror. Perhaps the Chapter's most eerie quality is that the Sons of Malice reportedly fight in utter silence, and those who have fought against them cite this as the prime source of the deeply disturbing aura surrounding them.Sons of MidnightStar GryphonsUnknownThe Sons of Midnight are a warband of Chaos Space Marines. They were once a Loyalist Chapter of Space Marines of unknown origin and Founding known as the Star Gryphons. They were corrupted after entering the Eye of Terror in 321.M37 as part of the Imperial Abyssal Crusade. It is unknown what they endured during their sojourn into the Eye, but by the time they made their way back into realspace, they had become the warband of Chaos Space Marines known as the Sons of Midnight.Sons of SlaughterWorld EatersUnknownThe Sons of Slaughter are a warband of Chaos Space Marines that splintered from the World Eaters Traitor Legion. Most recently, during the 13th Black Crusade, this warband fought alongside the monstrous Butcherhorde, a conglomeration of multiple World Eaters warbands led by the infamous Khârn the Betrayer, who led them in the slaughter of the Imperial world of Amethal in the Diamor System against the valiant defence of the Blood Angels Space Marine Chapter.Sons of SorrowDeath GuardFirst FoundingThe Sons of Sorrow is a warband or vectorium of the Death Guard Traitor Legion's 7th Plague Company. The infamous Plague Surgeon Nauseous Rotbone was once a member of the Sons of Sorrow vectorium before he was elevated to command rank by the Daemon Primarch Mortarion.Sons of the MaggotDeath GuardFirst FoundingThe Sons of the Maggot is a warband or vectorium of the Death Guard Traitor Legion's 5th Plague Company. The enduring popularity of Foetid Bloat-drones with the Traitor Legion's Death Guard Lords ensures that they are ferried in great numbers to the war zones in which the Death Guard fight, and deployed in swarms that darken the skies. This is especially true in the vectoriums of the 5th Plague Company, with warbands such as the Sons of the Maggot, the Suppurant Sting, and the Smogrot Brotherhood fielding great numbers of Foetid Bloat-drones in varying pack strengths and configurations.Sons of UlthunasUnknownUnknownThe Sons of Ulthunas were a formerly Loyalist Space Marine Chapter that turned Renegade against the Imperium of Man during the Ganymathian Betrayal. They are currently known as the Angels of Ecstacy and are Chaos Space Marines who serve Slaanesh, the Pleasure God. It is unclear if they are merely Renegade Space Marines who refuse to recognise Imperial rule or are now fully committed to the service of the Prince of Pleasure as Traitor Marines, though their increasingly mutated appearance and Chapter colour scheme would indicate that this is firmly the case.Sons of VengeanceUnknownUnknownThe Sons of Vengeance are a Renegade Chapter of Chaos Space Marines who turned to the service of the Ruinous Powers alongside the Silver Guards during the Obscuran Uprisings which ravaged the Segmentum Obscurus during the 34th Millennium.Sons of the EyeSons of HorusUnknownThe Sons of the Eye were a large warband of Chaos Space Marines dedicated to Chaos Undivided. The Sons of the Eye were a splinter warband of the Black Legion that was founded and commanded by the infamous Chaos Lord Drecarth the Sightless, the Blind Butcher of Irridous VII, a former Battle-Brother of the Sons of Horus who had fought alongside Abaddon during the Great Crusade and the Horus Heresy that followed. Always jealous of the Primarch Horus' favour for the Despoiler, the Sons of the Eye considered Abaddon a usurper. During the 6th Black Crusade, launched in 901.M36, Abaddon visited his wrath upon Drecarth the Sightless and his treacherous warband. Abaddon aided the Sons of the Eye in an assault on the Forge World of Arkreach, fighting side-by-side until the defenders were finally crushed. The triumphant Abaddon then slowly killed Drecarth, even as he made him watch every member of the Sons of the Eye bow before their new master.Soul DrinkersImperial FistsSecond FoundingThe Soul Drinkers were a Space Marine Chapter supposedly created during the Second Founding, who were allegedly created from the Imperial Fists gene-seed. The Soul Drinkers threw off the yoke of the Imperium which they believed was corrupt and were declared Excommunicate Traitoris by the Inquisition, but they were still loyal to the Emperor and their gene-seed was stabilised after numerous mutations. Recent events revealed that the Soul Drinkers were not in fact the genetic sons of the Primarch Rogal Dorn and the provenance of the Chapter is now unknown. The Soul Drinkers were ultimately destroyed as a Chapter in the late 41st Millennium when they worked with the Imperial Fists to end a Chaotic plot initiated by one of their own number, the Venerable Chaplain Dreadnought Daenyathos, to seize control of the Imperial Fists' mobile Fortress-Monastery, the Phalanx, and spread the power of Chaos across the galaxy. Though the Chapter has ceased to exist, the Imperial Fists honour its Astartes' final sacrifice in the defence of Mankind.Spears of OlympusUnknownUnknownThe Spears of Olympus were once a Loyalist Chapter of Space Marines of unknown origin and Founding. They were corrupted after entering the Eye of Terror in 321.M37 as part of the Imperial Abyssal Crusade. It is unknown what they endured during their sojourn into the Eye, but by the time they made their way back into realspace, they had become the warband of Heretic Astartes known as the Bloodlords.Star GryphonsUnknownUnknownThe Star Gryphons were once a Loyalist Chapter of Space Marines of unknown origin and Founding. They were corrupted after entering the Eye of Terror in 321.M37 as part of the Imperial Abyssal Crusade. It is unknown what they endured during their sojourn into the Eye, but by the time they made their way back into realspace, they had become the warband of Chaos Space Marines known as the Sons of Midnight.Steel BrethrenIron WarriorsUnknownThe Steel Brethren, also known as the Steel Brotherhood, are a warband of Chaos Space Marines drawn from the Iron Warriors Traitor Legion. They have been noted to make extensive use of gunship transports and Drop Pods in their planetary assaults. The Steel Brethren, like all warbands of the Iron Warriors, possess extraordinary skill and experience in siege warfare. The Steel Brethren, when away from the Iron Warriors' Daemon World of Medrengard, operate from the Chaos Cruiser identified as the Ferrum Invictus.Steel CobrasUnknownUnknownThe Steel Cobras were a formerly Loyalist Chapter of the Adeptus Astartes whose blasphemous worship of the Emperor of Mankind as an animal totem prompted a puritanical Crusade against them by the Ecclesiarchy, led by a particularly bombastic Cardinal. Faced with such an assault by the Imperium, the Steel Cobras turned to the service of Chaos to gain the power needed to defend themselves. They are known to have established a base of operations deep beneath the ammonia seas of the frigid world of Tukaroe VII. Although the Imperium is aware of these Renegades' existence, nothing short of an invasion by an entire Loyalist Space Marine Chapter is considered likely to dislodge them from their fortified seabed bunkers. The only other option is to perform an Exterminatus on the planet, a fate that may still befall Tukaroe VII should the Adeptus Astartes refuse to assault their wayward kin.Steel HeartUnknownUnknownThe Steel Heart is a Chaos Space Marine Renegade Chapter that was wiped out in 801.M41 when the Eldar Craftworld Lugganath attacked their stronghold. This headquarters is known to have been located somewhere in the western quadrant of the Segmentum Obscurus. Nothing else is currently known about this Renegade Chapter in Imperial records.Suppurant StingDeath GuardFirst FoundingThe Suppurant Sting is a warband or vectorium of the Death Guard Traitor Legion's 5th Plague Company. The enduring popularity of Foetid Bloat-drones with the Traitor Legion's Death Guard Lords ensures that they are ferried in great numbers to the war zones in which the Death Guard fight, and deployed in swarms that darken the skies. This is especially true in the vectoriums of the 5th Plague Company, with warbands such as the Sons of the Maggot, the Suppurant Sting, and the Smogrot Brotherhood fielding great numbers of Foetid Bloat-drones in varying pack strengths and configurations.Swords of KhargothSwords of PraesiumUnknownThe Swords of Khargoth are a warband of Chaos Space Marines who were formerly Loyalist Astartes of the Swords of Praesium Chapter. Descended from two once-loyal companies of those Space Marines, these Astartes turned to the service of Chaos out of desperation after being trapped on the world of Acropolis Vega within a Warp Storm for 70 Terran years.Swords of EpiphanyExorcistsUnknownThe Swords of Epiphany were a warband of Chaos Space Marines comprised of Daemon-possessed former neophytes of the Exorcists Chapter who escaped into the Warp from the Exorcists' homeworld of Banish with the aid of the Chaos-corrupted Ecclesiarchy Cardinal Rodrigo Nessun. They were eventually hunted down and destroyed by Exorcists Captain Veyon Armadel, who led what was known as "Armadel's Purge" against them.
