List of Chaos Space Marine Warbands - W: NameOriginFoundingSummaryWarband of SektothThousand SonsUnknownThe Warband of Sektoth is a large warband of Chaos Space Marines dedicated to the service of Tzeentch, the Changer of Ways. The Warband of Sektoth is a splinter warband of the Thousand Sons Traitor Legion that was founded and commanded by the infamous Chaos Sorcerer Sektoth the Whisper, a master manipulator of the power of the Warp. This warband is active in the Calixis Sector and the Screaming Vortex, one of two massive Warp Storms which separate the Calixis Sector of the Imperium from the Koronus Expanse.Warp GheistsThousand SonsUnknownThe Warp Gheists are one of the many exiled and estranged thrallbands 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 were exiled by their Daemon Primarch Magnus the Red following the disastrous casting of the sorcerous ritual, known as the Rubric of Ahriman. The Sorcerer at the thrallband's heart, the Exile Magister Nezchad Aratos, enacted a revivification ritual that restored his brethren's forms -- but only as far as their skeletons. He died in the process, leaving his kin to wander the galaxy.Warp GhostsUnknownUnknownThe Warp Ghosts are a Renegade Chapter of Chaos Space Marines of unknown Founding and origin, whose survivors now serve the Chaos God Nurgle, the Plague Lord. The Chapter betrayed the Imperium of Man and turned to Chaos, allying themselves with Abaddon's 13th Black Crusade in 999.M41. Being only a single Renegade Chapter, the Warp Ghosts have far fewer Chaos Space Marines and equipment than the original Traitor Legions, but are still renowned for their ferocity amongst the Forces of Chaos. The Bleak Brotherhood is believed to be a faction or warband of the Warp Ghosts.Warriors of AggannorNight Lords & Word BearersUnknownThe Warriors of Aggannor are a warband of Chaos Space Marines composed of an amalgam of warriors from multiple Chaos Space Marine warbands and the Traitor Legions. Numerous Night Lords and Word Bearers Traitor Marines swore allegiance to the Chaos Lord Aggannor and were responsible for a major Chaos incursion on Calibos III during Goge Vandire's Reign of Blood in the Age of Apostasy in the 36th Millennium.Warriors of MayhemUnknownUnknownThe Warriors of Mayhem are a warband of Chaos Space Marines of unknown origin and allegiance. This warband was first sighted by Imperial forces in 925.M41.Weeping LegionDeath GuardFirst FoundingThe Weeping Legion is a warband or vectorium of the Death Guard Traitor Legion's 5th Plague Company. The Weeping Legion is so named because its Plague Marines enter battle covered in the foul gore of their own continuously dripping wounds. With each layer of rancid filth and scabbing black blood that encrusts their armour, these clot-festooned warriors of the Death Guard become even more resistant to damage. Battling as part of the 5th Plague Company, the Weeping Legion are heavily supported by foul Daemon Engines that they daub with gobbets of their polluted vitae.Wolf BrothersSpace WolvesSecond FoundingThe ill-fated Wolf Brothers were the only known Second Founding Successor Chapter of Space Marines created from the gene-seed of the Space Wolves Legion. The Chapter was eventually forcibly disbanded by the Inquisition as a result of the rampant genetic instability and resulting mutation that appeared in the Chapter's Battle-Brothers. This instability may have been due to the Canis Helix gene that manifests itself at times in the Space Wolves themselves, transforming them into a terrifying creature known as a Wulfen. This trait was most obvious amongst the warriors of the Chapter's lost 13th Great Company. Some Wolf Brothers, however, chose to go Renegade rather than be liquidated and eventually became Chaos Space Marines in service to the Space Wolves' greatest enemies, the Thousand Sons Traitor Legion, and later to other Chaos Space Marine warbands such as the Red Corsairs. Some of these Renegades remain in the 41st Millennium, though the vast majority of the Chapter was liquidated millennia ago.Wolves of HorusBlack LegionUnknownThe Wolves of Horus are a large splinter warband of Chaos Space Marines that formerly belonged to the Black Legion and are dedicated to Chaos Undivided. The death of their Primarch Horus left many veteran Legionaries of the Sons of Horus craving a return to the halcyon days when the XVI Legion was known as the Luna Wolves. The Wolves of Horus chose to relive those early times, and venerate their dead Primarch by bearing his name. When Ezekyle Abaddon proclaimed himself the new master of the XVI Legion in the ruins of Maeleum, there were those who turned their back on the Despoiler. These Legionaries remained true to the memory of Horus or forsook all masters. The Wolves of Horus fled deep into the Eye, their current whereabouts unknown. They are known as the Thrice-Cursed Traitors to the Black Legion alongside the other Black Legion dissidents known as the True Sons and the now-extinct Sons of the Eye.The WrathUnknownUnknownThe Wrath are a Khorne Daemonkin warband that bring butchery to an unimaginable scale. Even in such murderous haunts as Commorragh and the Eye of Terror, these Daemonkin are whispered of with awe.Wrathful DeadWorld EatersUnknownThe Wrathful Dead are a warband of Chaos Space Marines that splintered from the World Eaters Traitor Legion. They are known to wear bone war helmets to signify the fact their skulls belong to Khorne. In this way they pledge their deaths to the glory of their wrathful god, robbing their enemies of their victory even should the foe cut them down to the last. 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.
