List of Chaos Space Marine Warbands - G: NameOriginFoundingSummaryGerminatorisunknownUnknownThe Germinatoris is a Chaos Space Marine warband dedicated to the Plague God Nurgle. The warband is composed of Plague Marines who prowl battlefields across the galaxy in order to grotesquely plunder the gene-seed of dead Chaos Space Marines. Once the gene-seed is within their grasp, the Germinatoris infect it with the viscous fluids that ooze from their rotting innards, in order to ensure the propagation of Nurgle's putrefying influence through the most potent of the Forces of Chaos.Gladiator Group 138World EatersUnknownGladiator Group 138 is a large warband of Chaos Space Marines drawn from the World Eaters Traitor Legion. Gladiator Group 138 was among the murderous alliance of Chaos Space Marines that served the Daemon Prince Kor Megron in assailing the Shrine World of Eydolim and other nearby worlds. This particular Chaos campaign was unusual, in that such overwhelming assaults and universal cooperation amongst the Forces of Chaos is normally the province of a Black Crusade. This speaks volumes of Kor Megron's powers for being able to manipulate so many disparate Chaos Space Marine warbands to do his bidding. The first assault Kor Megron and his allies undertook was against the Hive World of Jones Crispin World. With his fleet unexpectedly entering orbit over the planet, the Chaotic forces took the Imperial defenders by surprise. The World Eaters of Gladiator Group 138 led the assault against the largest hive city, Fort Crispin, massacring all in their path. The world of Eydolim was next to feel the wrath of Kor Megron. The bloodthirsty Khornate Berserkers of Gladiator Group 138 played a crucial role in the Chaotic assault on this planet. With Chainaxes wailing, they smashed through Eagle Gate, butchered the defenders and then continued into the waiting guns of the Imperial Guard.Glooming LordsDeath GuardFirst FoundingThe Glooming Lords is a warband or vectorium of the Death Guard Traitor Legion's 6th Plague Company. The Glooming Lords are a morose host of killers who march to war surrounded by colossal clouds of droning black daemon-flies. They harbour a particular hatred for the sorcerous warbands of Tzeentch, whose vibrant, colourful vigour they regard as insufferable. Belonging to the 6th Plague Company, the Ferrymen, the Glooming Lords are led by heavy formations of Blightlord Terminators. Their bodies seethe with crawling flies as they crush the enemy contemptuously underfoot.GorehandsUnknownUnknownThe Gorehands are a warband of Chaos Space Marines dedicated to the service of the Blood God Khorne. They participated in the triumphant final assault on Cadia by the Forces of Chaos during the 13th Black Crusade in 999.M41. Little else is currently known about them in Imperial records.GorehoundsUnknownUnknownThe Gorehounds are a warband of Heretic Astartes dedicated to the service of the Blood God Khorne.GoremongersUnknownUnknownThe Goremongers were 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. The Cholercauset suffered a total defeat and all in its ranks were slain, including the Goremongers, by the mysterious Legion of the Damned.Grand Order of Hermetic BladesThousand SonsUnknownThe Grand Order of Hermetic Blades is a Chaos Space Marine warband dedicated to the Chaos God Tzeentch, that was originally 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 believe it is their role to guide mortal souls into the afterlife, in the manner of the ancient psychopomp spirits they once worshiped on the Thousand Sons' lost Legion homeworld of Prospero. The warband now seeks to send mortals on to the afterlife they so relish using the most harrowing methods they can devise.Graven FistsUnknownUnknownThe Graven Fists 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 Twisted Blades.Graven SpectresUnknownUnknownThe Graven Spectres were a formerly Loyalist Space Marine Chapter of unknown Founding and origin. In 365.M41, the Renegade Chapter assaulted the relic world of Syban, intent on plundering its great stasis museum. During their rampage they unwittingly released the Daemon Prince Knor from his millennia-long slumber. Soon the renegades were fighting for their lives against Knor and his growing daemonic army. A single squad of Grey Knights Terminators arrived to assist the beleaguered world, but found themselves vastly outnumbered and unable to overcome their daemonic foes. With little chance of success, they sacrificed themselves by activating the planet's stasis failsafe, freezing it in time forever.Grey DeathIron DrakesUnknownThe Grey Death is a Renegade Chapter of Chaos Space Marines that is sworn to the service of Nurgle. They were once a Loyalist Chapter of Space Marines known as the Iron Drakes. They were corrupted after entering the Eye of Terror in 321.M37 as part of the Imperial Abyssal Crusade. At some point during their sojourn in the Eye, the Iron Drakes were corrupted by Nurgle on the Daemon World of Anathrax and became the Grey Death, ready and willing to spread their plague across the stars.Grey SlayersUnknownUnknownThe Grey Slayers were a formerly Loyalist Space Marines Chapter of unknown origin and Founding that became corrupted by Chaos. Inquisitor Thrax purged the Chapter of mutants and daemons, and the Chapter Master took his own life in shame. Untainted officers were raised up to lead the Chapter. The purge was apparently not quite thorough enough, as Inquisitor Thrax himself was soon afterwards corrupted by the Ruinous Powers and transformed into some sort of daemonic Chaos beast. The Grey Slayers' eventual disposition and fate remains unknown in current Imperial records.
