List of Chaos Space Marine Warbands - F: NameOriginFoundingSummaryThe FaithlessAlpha LegionUnknownThe Faithless are a large warband of Chaos Space Marines drawn from the Alpha Legion who operated off of the Chaos Battleship Anarchy's Heart. Formerly led by the Chaos Lord Arkos the Faithless, the warband is now believed to have been destroyed during the Siege of Vraks. Arkos himself is currently a prisoner of the Dark Angels Chapter of Space Marines.Favoured SonsDeath GuardFirst FoundingThe Favoured Sons is a splinter warband of Plague Marines that has become independent of the Death Guard Traitor Legion's central command. Having broken away from Mortarion's rule, the Favoured Sons seek Nurgle's blessings for themselves. Each Heretic Astartes of this warband tries to outdo his brothers in the hope of earning daemonhood. Their master, Vermithrus the Blighted, is a Daemon Prince who surrounds himself with gruesome champions of Nurgle.Fecund OnesDeath GuardFirst FoundingThe Fecund Ones is a warband or vectorium of the Death Guard Traitor Legion's 7th Plague Company. When an Imperial Agri-world is infected with one of the innumerable poxes of Nurgle, the warband known as the Fecund Ones are often the culprits. Belonging to the alchemically-gifted 7th Plague Company, the Fecund Ones are masters of brewing virulent blights and parasitic phages. They delight in sowing these putrescent gifts among the food supplies of the Imperium's oblivious masses, leading many worlds they invade to be crippled by either hideous vomiting plagues or widespread famine and starvation.Filth-favouredDeath GuardFirst FoundingThe Filth-favoured are a warband or vectorium of the Death Guard Traitor Legion's 4th Plague Company. They are commanded by a Death Guard Sorcerer and are one of the few Death Guard warbands which likes to enter battle amidst living carpets of Nurglings, the Lesser Daemons of the Plague God Nurgle. Little else is known about the Filth-favoured in current Imperial records.Fire ReaversUnknownUnknownThe Fire Reavers are a fanatical warband of Chaos Space Marines who are highly devoted to the Ruinous Powers, willingly offering themselves up to the Chaos Gods for possession by immaterial beings. Members of the Fire Reavers henceforth, become Possessed Chaos Space Marines, which is viewed as a great honour within the warband. This Renegade Chapter is known to still rule over the home world gifted to them by the Imperium. There is little else known about this obscure warband in current Imperial records.Fists of BrassUnknownUnknownThe Fists of Brass were a host of Khorne Daemonkin of unknown origin. Almost nothing is known about them from Imperial records aside from their involvement in a fatal clash with WAAAGH! Badstomp in 301.M40.Fists of OlchisUnknownUnknownThe Fists of Olchis were once a Loyalist Chapter of Space Marines of unknown origin and Founding. They were lost 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, and they were declared Perditas by the Imperial Inquisition, who feared that if the Chapter still existed, it had been corrupted by Chaos.Flame FalconsUnknown21st FoundingThe Flame Falcons was one of the cursed Space Marine Chapters created during the 21st Founding, the so-called 'Cursed' Founding. This Chapter was almost completely wiped out by the Inquisition before a hundred standard years had passed following its Founding. The cause of the Inquisition's attack was the fact that during an engagement, members of the Chapter spontaneously burst into flame, which they believed was a gift from the Emperor of Mankind. The members of the Inquisition did not share the Chapter's views, and when they returned to their home world of Lethe, they were attacked and almost completely destroyed by a force of Grey Knights.The Flawless HostShining BladesUnknownThe Flawless Host is a Chaos Space Marine warband in the service of Slaanesh. The members of the Flawless Host believe they are the embodiment of justice and purity. Their gene-seed was once free from Chaotic taint, and the rigid mental training of their former incarnation as the Loyalist Space Marines known as the Shining Blades, gave the Chapter 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.Flickering BladesEmperor's ChildrenUnknownThe Flickering Blades are a Renegade Warband of Chaos Noise Marines which broke away from their parent Traitor Legion the Emperor's Children. Led by the infamous Noise Champion Volupus, this son of Chemos, decided to go off on his own to form his own warband. In battle, these warriors stride into combat wielding lithe swords that sing songs of death with every swing. From out of their twisted armour stretch numerous writhing tongues, each mutant maw licking its lips in lewd anticipation of the blood-splattering of close combat.The FlylordsVengeance ChapterUnknownThe Flylords are a warband of Chaos Space Marines. They were once a Loyalist Chapter of Space Marines of unknown origin and Founding, known as the Vengeance Chapter. 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 Flylords.Foresworn (Word Bearers)Word BearersUnknownThe Foresworn are a warband of Chaos Space Marines drawn from the Word Bearers Traitor Legion. The Foresworn were among the murderous alliance of Chaos Space Marines that served the Daemon Prince Kor Megron in assailing the world of Eydolim and other nearby worlds sometime during the latter 41st Millennium. This particular Chaos campaign was unusual, in that such overwhelming assaults and universal cooperation is normally the province of a Black Crusade. This speaks volumes of Kor Maegron's powers of being able to manipulate so many disparate Chaos Space Marine warbands to do his bidding. The hateful wrath of the Daemon Prince drew not only the Foresworn together, but also forged the great alliance between the disparate Chaos Space Marines and renegade bands. Indeed, as the fighting within Eydolim reached its zenith, it was Kor Megron who wrought the summoning of the daemonic host.Foresworn (World Eaters)World EatersUnknownThe Foresworn are a large warband of Chaos Space Marines drawn from the World Eaters Traitor Legion. The corrupted Astartes of this warband are all Khornate Berserkers. The Foresworn are led by the infamous Chaos Lord Kossolax the Foresworn.ForgebornUnknownUnknownThe Forgeborn are a warband of Chaos Space Marines of the Black Legion led by the Warpsmith D'vok the Unmaker. They became engaged in a conflict with the Craftworld Aeldari of Craftworld Saim-Hann when they sought to conquer the Exodite Maiden World of Daethe in the Nachmund Gauntlet.The FracturedJusticarsUnknownThe Fractured are a warband of Chaos Space Marines. They were once a Loyalist Chapter of Space Marines of unknown origin and Founding, known as the Justicars. 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 the Justicars made their way back into realspace, they had become the warband of Chaos Space Marines known as The Fractured.
