Gehemahnet - Gehemahnet: A Gehemahnet is a massive spire capable of channeling Warp energy that is built by the Chaos Space Marines of the Word Bearers Traitor Legion on newly conquered worlds, as well as on their homeworld of Sicarus, a Daemon World located deep in the Eye of Terror. A Gehemahnet's purpose is to channel Warp energy to the world it is located on in order to transform it into a Daemon World. The material for every Gehemahnet is gathered from the rubble of buildings destroyed during the initial invasion of the world by the Word Bearers. The substance that bonds all the blocks is the "blood mortar" made from the bodies of the dead inhabitants of the unfortunate world. The creation of a Gehemahnet is a monumental undertaking, and the majority of the labour is done by millions of slaves under the direction of cruel overseers drawn from the Traitor Legion. If a slave dies from fatigue or exhaustion their bodies are simply added to the blood mortar mixture. Manufactora and hellish forges are built in close proximity to the vile edifice, providing raw material for the construction of the tower as well as the creation of Daemon Engines -- spider-like cranes created for the sole purpose of assisting in the construction of the tower.Gehemahnets work like a magnet for daemons of the Warp that are trying to break through the dimensional barrier between the Warp and realspace so that they can infest the newly conquered world. The barrier between the Realm of Chaos and the material plane are thin in the proximity of the Gehemahnet. Daemonic entities strain from beyond to cross the thin walls and enter the physical world. When the tower is finally completed the barriers are stripped away like flesh from bone and the daemons are able to take corporeal form and transform the doomed world into the latest incarnation of a Chaotic hell.
Gehenna Campaign - Gehenna Campaign: The Gehenna Campaign was conducted by Commander Dante, Chapter Master of the Blood Angels Space Marine Chapter, and its 3rd Company in 955.M41. They battled against the Necron legions of Szarekh, the Silent King, and leader of the Triarch, amidst the dusty wastes of the Hive World of Gehenna.For three solar weeks, neither side could seize the upper hand, with Dante's tactical brilliance stretched to its limits in countering the time-space manipulations of the Silent King.The stalemate was broken only when a Tyranid splinter fleet entered orbit, forcing the two armies to break off hostilities and fight the common foe. The impromptu alliance proved to be the Tyranids' undoing.Following the final battle at Devil's Crag, Dante and the Silent King went their separate ways, both forces too battleworn to guarantee victory over the other, and, at least for the Blood Angels, the idea of turning on those they had so recently fought alongside proved a rather distasteful one.
Gellar Field - Gellar Field: The technology that generates a protective Gellar Field (also spelled Geller Field) around an Imperial starship intended for faster-than-light travel was invented along with the Warp-Drive by Humanity sometime in the 18th Millennium AD during the Age of Technology.The technology, formally called a "Gellar Field Device," allowed Warp-capable starships and their occupants to survive the extremely hazardous environment of Warpspace, also known as the Immaterium.The Gellar Field protects the starship and its occupants from the hostility of the psychically-reactive Warp environment itself as well as from the predation of Warp entities such as Daemons and Enslavers.The device worked by literally projecting a bubble of realspace around the starship where the physical laws of space-time continued to function; the technological means by which this was accomplished seems to have changed over time.
Gellar Field - Imperial Gellar Field Device: The Gellar Field Device emits an energetic, invisible force field comprised of unknown subatomic particles called a Gellar Field, which essentially maintains a bubble of real space-time around a starship travelling through the Warp using the power of its sublight drives after utilising its Warp-Drive to pierce the veil between the physical universe and the Warp.Since entities native to the Immaterium cannot breach its boundaries to enter the physical universe except under certain very specialised circumstances, creatures native to the Warp are repelled from the boundaries of the projected Gellar Field.Warp entities would tear the starship apart to reach and consume the souls of the mortal crew. As such, the field must be active at all times. For the field to work, the starship must be entirely sealed; no open entrances that would breach the field's protective envelope are allowed.The weakening, failure, or collapse of its Gellar Field while a starship is transiting through the Warp would be completely disastrous, as was discovered by the crew of the Imperial frigate Eisenstein during its famous flight to Terra from the Battle of Isstvan III to tell the Emperor of Mankind of the betrayal of his favoured son Horus.By the time of the Great Crusade in the late 30th Millennium, some Gellar Field generators created their field of reality around a voidship from the dreams of a psyker kept in a hibernating, comatose state. In their coma, they psychically project an aura of normality around the ship in which the physical laws of realspace still apply.A voidship using this type of Gellar Field Device effectively shields itself within the dreaming psyker's projections of reality which serves as the "bubble" of realspace that pushes back the Immaterium for a time. However, these psykers generally lose their lives through this process after a relatively short time, which means that any Warp-capable voidship using this type of Gellar Field Device must have new psyker "batteries" to replace the old at a consistent pace.It must be noted that, while efficient, a Gellar Field is by no means infallible; indeed, one has been broken on many occasions, to the great misfortune of a starship's crew and passengers. The commonplace disappearance of starships in the Warp is often attributed to Gellar Field failure and the Imperium has come to accept that a small but significant percentage of its interstellar traffic will be consistently lost to accidents of this kind.
Gellar Field - Notable Gellar Field Device Variants: Belecane-Pattern 90.r Gellar Field - The Forge World Belecane in the Calixis Sector has long been associated with the construction of protective barriers, void shields, Stasis Fields, and Gellar Fields. The 90.r Gellar Field was an experimental type of Warp field which offered enhanced Warp-handling capabilities, allowing the voidship to slip through the Warp like a predatory razorfish. Unfortunately, it was prone to an inexplicable "flicker" during prolonged use which would allow daemonic entities ingress to the vessel during Warp transit, meaning it is rarely used.
Gellar Field - Orks: Orks do not seem to generate a Gellar Field around their admittedly patchwork spacecraft and their method of surviving transit through the Warp unharmed is unknown, though it is possible that their latent, collective psychic powers help make a repulsive Warp barrier instinctively.It is probably safe to assume that other intelligent alien races have their own method of shielding their starships if they travel through the Immaterium, be it a variant of the Gellar Field or some other method which replicates the same protective effect.
Gellar Field - Necrons: The Necrons do not travel through the Warp at all when they use their unknown phase technology or Dolmen Gates to move around the Milky Way Galaxy, so they have no need for a Gellar Field alternative. This is also true of the Aeldari and Drukhari when they use the Webway.However, a much more advanced variant of the technology may have been utilised to create and maintain the Webway of Warp tunnels that they use to travel interstellar distances. The material which comprises the Webway is itself psychically shielded through unknown means from intrusion by malevolent Warp entities.
Gellar Field - Tyranids: The Tyranid Hive Fleets also do not travel through the Warp. Instead, they use Bio-Ships called "Narvhals" that manipulate their intended destination's own gravity to compress realspace into a type of gravitic transit corridor or wormhole, allowing the Hive Fleets to cover vast distances very quickly. This method grows far less efficient as they draw closer to their destination, extending the travel time by standard years, or even solar decades, as they must slow to more conventional methods of propulsion as they near a star system.The Tyranid Hive Mind's psychic Shadow in the Warp makes Warp travel and astropathic communication much harder if not impossible for Imperial starships and psykers. It is possible the massive psychic presence of the Hive Mind in the Warp disrupts both the Immaterium's local geometry and possibly an Imperial starship's Gellar Field.
Gellar Field - T'au: The T'au make use of the ZFR Horizon Accelerator Engine, also known informally as the "ZFR Drive" to cross interstellar space at close to the speed of light, utilising the relativistic time dilation effects of such journeys to minimise the time experienced by a vessel's passengers in transit.As their vessels remain wholly in realspace and never cross into the Immaterium, the T'au have no need for the use of a protective technology like the Gellar Field. This may change as the T'au become more technologically familiar with the existence of the Warp and its many dangers.
Gellar Field - Leagues of Votann Geller Rampart: The Leagues of Votann make use of Gellar Field technology that they call a "Gellar Rampart." As with much of Kin technology, the Gellar Rampart is of a far more advanced design and possesses much greater reliability within the Warp than its Human counterpart.
Gene-Seed - Gene-Seed: Gene-seed is the colloquial term used amongst the Adeptus Astartes for the genetic material that allows for the creation of the superhuman Space Marines.The gene-seed is actually the catch-all term for those germ cells and viral machines that have been genetically-engineered to develop into the various organs that are implanted into a normal Human adolescent male to transform him into a transhuman Astartes.All of the gene-seed was originally crafted in the 30th Millennium by the Emperor of Mankind and the scientists of the Biotechnical Division in His gene-laboratories deep beneath the Himalazian (Himalayan) Mountains for this purpose using the genomes of each of the 20 primarchs as a template.The term is most commonly used to refer to the contents of the Astartes Progenoid Glands which must be harvested by a Space Marine Apothecary so that its genetic material can be used to create a new generation of Astartes. There are 19 types of gene-seed, each corresponding to one of the 19 specialised organs implanted into the body of a Human male to create a Space Marine.As many of these implants are neural in nature, it is important to note that for many of these implantations the subject must be awake for the surgery and the mind cannot be dulled by the use of painkillers.Many of these organs are cultured in vitro from the gene-seed, whilst others require that the gene-seed be injected into the Aspirant's body and then grow into a new organ using the implantee's own physiological processes. All Space Marine Chapters use the gene-seed organs to unleash and control the metabolic processes that transform an ordinary mortal into a Space Marine.The gene-seed itself is encoded with all the genetic information needed to reshape ordinary Human cell clusters into the special organs Space Marines possess in those instances where they are not directly implanted after being cultured outside the body.The gene-seed contains genetically-engineered viral machines which rebuild the male Human body according to the biological template contained within it and originally crafted by the scientific acumen of the Emperor.However, even from the beginning of the Astartes' existence, there has never been a set, standardised method to activate these transformative functions of the gene-seed. As a result, each Chapter may pursue its own methods and rituals surrounding the process of creating a new Space Marine.During the First Founding of the 30th Millennium when the 20 Space Marine Legions were created, the process was still highly experimental and many different ways of controlling and managing the transformation from mortal man into Astartes were tried.This led to the Space Wolves using the ritual known as Blooding, the Imperial Fists using the process known as the Hand of Faith, the White Scars conducting the Rites of the Risen Moon and the Blood Angels using the ritual of Insanguination.
Gene-Seed - Gene-Seed Implants: Since the First Founding, the Chapters of the Adeptus Astartes have lost the ability to engineer new gene-seed or implant Astartes organs from scratch. They also do not often possess enough stable genetic material to directly culture all 19 implants available to their Chapter due to the loss or rampant mutation of the gene-seed for one or more organs.All Chapters are different, but the "purest" Chapters in this respect are the Grey Knights, the Ultramarines, and the Dark Angels, who have maintained a large enough supply of stable gene-seed to develop all 19 fully functioning Astartes organ implants. It is for this reason that the Ultramarines and the Dark Angels have more Successor Chapters than any of the other First Founding Chapters.However, all known Astartes Chapters possess the gene-seed required to culture the Black Carapace, as this is necessary for a Space Marine to use his power armour, and the Progenoid Glands, without which the Chapter would be incapable of creating new Astartes.The implantation of new gene-seed or gene-seed organs has over the centuries turned into a near-religious ritual. Some Astartes will need further operations after the initial implantation procedure to fix imbalances caused by poor surgery or their own body's poor metabolic adjustment to the hormonal and physical changes initiated by the implants.
Gene-Seed - Primaris Gene-Seed: Though they now stand a step above their Firstborn Astartes brethren, all Primaris Space Marines were still created using the original gene-seed of their primarchs, like all other members of the Adeptus Astartes. Some voices within the Imperium now worry how this new type of transhuman warrior will react to the many genetic quirks and flaws found in the gene-seed of some of the more unusual Chapters, particularly given the long history of fiascoes that have resulted from attempts to alter the Emperor's original work.In the pursuit of his attempt to improve upon the original Space Marine template, Archmagos Dominus Belisarius Cawl collected samples of the genomes of all twenty of the original primarchs, including those deemed Lost or Traitors, though the resurrected Primarch Roboute Guilliman made clear to his overeager servant that Primaris Marines were to be created only from the lines of those of his brothers who led the nine Loyalist Space Marine Legions.It is known that in addition to the general advancements in their gene-seed, Primaris Space Marines possess three additional gene-seed implant organs compared to their Firstborn brethren and that their gene-seed is far more genetically stable than that of their forerunners.Primaris Space Marine gene-seed has only a .001% chance of genetic deviancy from the original baseline with the passage of each generation, which makes it nearly immune to the severe genetic instability suffered by Chapters such as the Blood Angels and Space Wolves over the course of their existence.Nearly every Space Marine created since the First Founding possesses nineteen specialised organs derived from this gene-seed. The Primaris Marines, however, are implanted with a further three additional organs. It was the Sangprimus Portum, a device containing potent genetic material originally harvested from the primarchs, that allowed for this breakthrough.Entrusted to Cawl by Guilliman shortly after the Second Founding in the early 31st Millennium, this device resulted in a new breed of Adeptus Astartes that were deployed en masse in the Ultima Founding of ca. 999.M41.Due to Cawl's interpretation of his orders and the millennia-spanning labour of his task -- during which Guilliman was mortally injured and suspended in stasis on Macragge -- the secrets of these new Primaris Marine organs were not released until late in the 41st Millennium.
Gene-Seed - Primaris Organs: The Primaris Space Marines possess all of the nineteen gene-seed implant organs that have been gifted to their original Firstborn Astartes brothers, as well as three more that only they possess, for a total of twenty-two. These new gifts of Belisarius Cawl's genius further enhance their transhuman status and ability to bring the Emperor's justice to a galaxy shrouded in darkness and despair. These additional implanted organs include:Sinew Coils (The Steel Within) - The Primaris Space Marine's sinews are reinforced with durametallic coil-cables that can contract with incredible force, magnifying his strength as well as giving his body another layer of defence. A Primaris Space Marine can crush a man's skull in his hand, break Flak Armour to flinders, or even bite through a metal cable should the need arise.Magnificat (The Amplifier) - A small, thumbnail-sized lobe that is inserted into the brain's cortex. The Magnificat secretes hormones that increase the body's growth functions whilst also intensifying the function of its other transhuman implants, especially those of the Biscopea and the Ossmodula. As a result, Primaris Astartes are even taller by a Terran foot (approximately .31 metres) and physically stronger than their Firstborn counterparts. In truth, the Magnificat is but half of the true, dual-valve Immortis Gland (the so-called "God-Maker") that the Emperor created for His primarchs. However, Archmagos Cawl could only find materials and genetic blueprints to build the Dextrophic Lobe (the right half of the Immortis Gland), while plans for the Sintarius (the left half) that would complete the original super-organ had been wholly eradicated from Imperial records of the Primarch Project. Whether this was done by the Emperor's own hand or by some nefarious source, Cawl could not tell.Belisarian Furnace (The Revitaliser) - This is a dormant organ that connects to both Astartes hearts. In times of extreme stress, or should the warrior's body undergo violent, damaging trauma, it expels great bursts of self-synthesized chemicals -- a hyper-cocktail that simulates the biological action of combat stimms while also aiding in the rapid regrowth of tissue, bone and muscle. The gland then falls dormant again, and takes some time to metabolically build itself up once more for the next usage.
Gene-Seed - Canis Helix: The Canis Helix, also sometimes called "The Spirit of the Wolf," is the term for the unique mutation of the gene-seed received by the neophytes of the Space Wolves Chapter in addition to the normal gene-seed organ implants that were created using the genome of their Primarch Leman Russ.The Canis Helix also serves as the genetic catalyst that initiates the metabolic process of transformation from a mortal man into a superhuman Astartes.The inherent instability of this genetic material is what causes the Astartes of the Space Wolves to develop their wolf-like qualities, chief among them their extremely good sense of smell and their elongated canine fangs, which is their most identifiable physical feature.The Canis Helix also causes the Space Wolves to grow unusual amounts of body hair throughout their lives and in some individuals is the cause of their rapid degeneration into the feral mutants known as the Wulfen.
Gene-Seed - Creating Gene-Seed Implants: The gene-seed of a Space Marine Chapter is passed down through the Progenoid Glands, the 18th implant that collects and stores genetic data. There are two of these glands, one in the throat, and one in the reinforced chest cavity.This is done mainly for safekeeping, but it also provides an opportunity for a Chapter that has suffered massive losses to regenerate itself over a long period of time.The germ cells within a Progenoid Gland mature over a period of five to ten Terran years, and can be harvested at any time after reaching maturity, up until a short time after death. Each gland contains the seed for one of each of the specialised organs necessary to create a Space Marine.After removal, samples are taken and cultivated to grow new organs and allow a Chapter to increase in number (although those Chapters that strictly adhere to the dictates of the Codex Astartes will generally avoid doing this because the Codex dictates that a Chapter must have only 1,000 Space Marines at maximum).Thus, an Astartes' death means another will be added to the ranks, and the fallen hero lives on in some small way in each new warrior that follows in his footsteps using the gene-seed replicated by and harvested from his body.In the event of a Chapter suffering disastrous losses of its gene-seed, it may become necessary for the Apothecaries of the Chapter to use test-slaves to breed enough new gene-seed to bring the Chapter rapidly back up to full strength.These test-slaves are always Human males, usually the condemned Imperial criminals that would otherwise be turned into servitors. They are kept inside an artificial environment within the Chapter's fortress-monastery alive and partly conscious, but unable to leave their transparent plasteel gestation chamber for the full 5-10 year maturation process.Needless to say, this solution is far from ideal, and is regarded as a last option to keep a Chapter alive. This method is also used by the Adeptus Mechanicus to create the large amount of gene-seed necessary for the Founding of a new Chapter since no existing Chapter could spare 1,000 copies of its gene-seed.However, as each Chapter is required to tithe 5% of its gene-seed away to Mars to be checked for genetic purity, it is possible that the Imperium could build up a collection of gene-seed, and found new Chapters that way en masse.
General Order 169 - General Order 169: General Order 169 was a command issued by Lord Commander Sebiascor Ebongrave for the quarantine and blockade of the worlds of the Arkalas Cluster in the Jericho Reach in 786.M41.The order applies to any and all forces aligned with the Achilus Crusade, and prohibits all travel to and from the planets of Argoth, Rheelas and Kaggeran under penalty of death.The quarantine is enforced by vessels drawn from Battlegroup Atlas, which patrols the three systems. It is under strict orders to interrogate any Imperial vessels that enter the systems, giving one opportunity to trespassers to state their identities before opening fire, while firing without hesitation against non-Imperial vessels.In addition to this basic duty, the patrol ships also monitor the state of the worlds behind their cordon, reporting back to Lord Commander Ebongrave regularly.Only at the express order of the lord commander, or by Inquisitorial mandate, can a vessel break the quarantine and venture to these Forbidden Worlds, though such permission is seldom given.
Genesis Chapter - Genesis Chapter: The Genesis Chapter is a Loyalist Second Founding successor or "Primogenitor" Space Marine Chapter of the legendary Ultramarines.First amongst the Ultramarines' Primogenitor Chapters to be raised (and hence their name), the Genesis Chapter is dogmatically loyal to the Imperium of Man and the memory of their Primarch Roboute Guilliman, and can be counted upon to fight at the Ultramarines' side without hesitation.The Chapter's homeworld is the planet Newfound which is located a comparatively short distance to the galactic northwest of the Ultramarines' Realm of Ultramar, and its Astartes commonly undertook at least one pilgrimage to the Shrine of the Primarch on Macragge before Guilliman's resurrection in ca. 999.M41.
Genesis Chapter - Chapter History: Of the thousand or so Space Marine Chapters extant throughout the Imperium the great majority can be considered Codex Astartes-compliant. One such Chapter is the Genesis Chapter.Founded in the dark days of the Horus Heresy the Genesis Chapter is a Primogenitor or "First Born" Chapter, created during the Second Founding. Like its forebears, the Genesis Chapter is composed of highly disciplined and courageous warriors.Upon their inception, the Genesis Chapter's first battle wrested the planet Newfound from the clutches of the traitorous Word Bearers, and it has been their Chapter planet ever since. The Chapter has remained dogmatically faithful to the teachings of the Codex penned by its Primarch for nearly ten millennia.
Genesis Chapter - Indomitus Crusade: The Genesis Chapter has always had the proud distinction of being the very first of the Primogenitors of the Ultramarines Legion. It was formed from the noblest Ultramarines Veterans who survived the Horus Heresy.They have always venerated Roboute Guilliman, and were one of the first Chapters to seek out the primarch upon his revival in ca. 999.M41 following the Ultramar Campaign of the 13th Black Crusade.They knelt as one and pledged themselves to the eternal service of the resurrected lord commander of the Imperium. As such, they were among the first of the existing Chapters of the Adeptus Astartes to have their ranks bolstered by Primaris Space Marines created during the Ultima Founding.
Genesis Chapter - Notable Campaigns: Cleansing of the Ulik Sector (997.M41) - In 997.M41 a series of Exterminatus missions were carried out across the Ulik Sector by Space Marines of the Death Strike, the Flame Falcons and the Iron Hands Chapters. The Genesis Chapter performed a series of destructive missions on those worlds in the Ulik Sector not yet consumed by Hive Fleet Leviathan, in order to prevent the Tyranid Hive Mind from gaining momentum and further fuelling itself on precious bio-resources.WAAAGH! Irontoof Campaign (998.M41) - In 998.M41 the Genesis Chapter, alongside its Primogenitors the Ultramarines, engaged the growing might of the Ork WAAAGH! Irontoof and successfully threw back the Greenskin horde.Plague Wars (ca. 012.M42) - The Genesis Chapter contributed 6 companies to the "Spear of Espandor" campaign of the Plague Wars that resulted in the Loyalist forces retaking the Espandor System and cutting off the supply lines of the Nurglite invasion.
Genesis Chapter - Chapter Organisation: Following the break-up of the Space Marine Legions into smaller fighting forces during the Second Founding, Roboute Guilliman laid down the organisational dictates in the Codex Astartes that would become a part of every Chapter from then on. Though some would later stray from the precise structure laid out in the Codex, most Chapters remain faithful to its teachings.The Genesis Chapter is split into 10 companies, each 100 Space Marines strong and led by a Captain. The 1st Company consists of battle-hardened Veterans and is, invariably, the most powerful and skilled within the Chapter. It is also the only company capable of fielding warriors clad in Terminator Armour.The 2nd through 5th Companies are the Chapter's Battle Companies and these are composed of a mix of Tactical, Assault and Devastator Squads. Each Battle Company is a self-sufficient battlefield unit, capable of meeting any threat and defeating it. These form the backbone of the Chapter and bear the brunt of the fighting.The 6th through 9th Companies are the Reserve Companies of the Chapter and each one comprises squads of one particular type of Astartes. The 6th and 7th Companies are Tactical Companies, the 8th Company is the Assault Company and the 9th Company is the Devastator Company. The 10th Company is made up of Scout Marines who are the Chapter's newest recruits. These divisions were decided upon ten thousand years ago by Roboute Guilliman and have served the Chapter well since that day.
Genesis Chapter - Chapter Recruitment: All Genesis Chapter Scout Marines once undertook a pilgrimage to Macragge to look upon the visage of the primarch, frozen in timeless stasis, and believed their training to be incomplete until they had knelt in spiritual communion for at least an entire solar day at the feet of their gene-father.Since Roboute Guilliman's resurrection, this custom has become obsolete.
Genesis Chapter - Chapter Combat Doctrine: As befits a Chapter that is made up of the scions of Guilliman, the Genesis Chapter emulates their forebears by strictly adhering to the tenets laid down in the Codex Astartes. Since their inception, they have fought in the manner described in its holy pages.Other Chapters may freely interpret the words of Guilliman but, to the Genesis Chapter, such deviation is unthinkable. The Codex has literally hundreds of pages devoted how to overcome any given tactical situation and emerge victorious in the name of the Emperor.Each Genesis Chapter battle-brother does his utmost to study and memorise the Codex so as to enable an individual company to have an entire record of the Codex' teachings contained within the mind of every single Space Marine. Because of their close ties with their Progenitor Chapter, the Genesis Chapter and the Ultramarines frequently undertake joint operations.Genesis Chapter squads will routinely fill gaps within the Ultramarines' companies should they fall below strength due to attrition or other commitments. This includes the secondment of individual Genesis Chapter battle-brothers to fill empty specialist positions such as that of Librarians and Techmarines.
Genesis Chapter - Chapter Beliefs: As a Primogenitor Chapter, the Genesis Chapter is generally held to be the closest of the Ultramarines' successors, both doctrinally and astrographically. The Genesis Chapter are dogmatically loyal to the memory of Roboute Guilliman, whom they venerate not only as their founder, but as the saviour of the Imperium.These Astartes hold to the wisdom of the Codex Astartes in every possible way. The Chaplains of the Genesis Chapter regard the words of the Codex Astartes as utterly sacrosanct, going to great lengths to ensure the Chapter's adherence to its tenets.If there is a point of contention in regards to the Codex, it is thoroughly debated, with the opinions of the Ultramarines' Chaplains as a recourse for final ratification. This ensures there is no doctrinal rift between Progenitor and Primogenitor.
Genesis Chapter - Chapter Gene-Seed: The Ultramarines gene-seed is by far the purest stock of Astartes gene-seed in the Imperium and there are no known aberrations in its genetic structure. Every one of the esoteric organs utilised in the arduous creation of a Space Marine by the Genesis Chapter is fully functional.The terrible schism known as the Horus Heresy highlighted weaknesses inherent in the gene-seed of several other Space Marine Legions and this was exacerbated by the accelerated zygote harvesting techniques used to keep the Legions up to full strength during that terrible conflict.When the Legions were broken down into Chapters after the Heresy, a genetic repository was set up on Terra to store their gene-seed and monitor its purity.As the largest of the Space Marine Legions, the Ultramarines' contributions to this resource was greater than that of any other Legion and, as a result, their gene-seed became the stock type for many of the Second Founding Chapters.Those Chapters created from the Ultramarines gene-seed stored on Terra are known, collectively, as the Primogenitors or "first born", and they also venerate Roboute Guilliman as their founding father.
Genesis Chapter - Notable Genesis Chapter Astartes: Chapter Master Eorloid - Eorloid is the current master of the Genesis Chapter.Captain Portan - Portan is the captain of the Genesis Chapter's 2nd Company. He was made the Tetrarch of Andermung, a world in the southern reach of Ultramar.Captain Aeneas - Aeneas was the captain of the Genesis Chapter's 3rd Company. He met his end onboard the Strike Cruiser Diadem Mantle when the 3rd Company's assault against the Night Lords' 10th Company failed. Afterwards, Talos Valcoran ordered the Echo of Damnation to destroy the vessel.Tolemion Saralen - Tolemion Saralen was a Company Champion of the Genesis Chapter's 3rd Company. A formidable warrior who was zealously loyal to the Emperor, he took part in the assault conducted by his Chapter on Tsagualsa against the treacherous Night Lords warband of the Chaos Champion Talos Valcoran. Wielding his mighty Thunder Hammer he fought against the "Soul Hunter"'s 1st Claw squad. Unfortunately he did not survive the encounter as he was impaled on Talos' Power Sword by the severely wounded Night Lord known as Xarl. Tolemion praised the Emperor before being beheaded. However, Xarl died from blood loss from the wounds Tolemion inflicted upon him soon after their confrontation.
Genesis Chapter - Chapter Relics: Tulius' Insight - Tulius' Insight is an ancient treatise written by the Genesis Chapter's hero Tulius. Those who adhere most fervently to the Codex Astartes occasionally find service in the Deathwatch to be a trial, with no standard Chapter or squad configurations taking precedence over the urgent needs of the Vigil. Such battle-brothers are often pointed to the writings of Tulius of the Genesis Chapter, who applied the core doctrines of the Adeptus Astartes to the duties of the Deathwatch with exacting thoroughness. His original work, a collection of annotations to the Codex Astartes itself, is kept within a stasis-vault in Watch Fortress Erioch, and granted to the most trusted Kill-team leaders to assist them in their stratagems.
Genesis Chapter - Chapter Colours: The Genesis Chapter parallels their Ultramarines forebears very closely in terms of Chapter markings and badges of rank. The Genesis Chapter primarily wears red power armour. The Aquila or Imperialis on the chest guard is yellow.The white squad symbol on the right shoulder guard designates tactical specialty -- battleline, close support, fire support, Veteran, or command. A black High Gothic numeral is stenciled on the centre of the squad specialty symbol which indicates squad number.The colour of the shoulder plate trim indicates company number in accordance with the dictates of the Codex Astartes -- i.e. white (1st Company), yellow (2nd Company), red (3rd Company), green (4th Company), etc.The sergeants' badges are blue instead of red but otherwise there are few differences between the Chapters in terms of rank and company iconography.Senior sergeants of Veteran status are proclaimed by a golden skull added to the helm, while less senior Sergeants instead wear a white skull in its place.Veteran status is indicated by a white helmet stripe.
Genesis Chapter - Chapter Badge: The Genesis Chapter's badge is a black Greek letter Lambda or an upside-down "V" on top of a black-outlined white triangle. This is centred on a field of red.The effect of the design is to create a Greek letter Alpha, which is an ancient Terran symbol for a new beginning, or "genesis."

Genestealer - History: Few Tyranid creatures have earned such a terrible reputation or caused as much damage to the Imperium of Man as the Genestealer. Encountered long before the first tendrils of the hive fleets reached the galaxy, they were thought to be little more than another unusual and deadly xeno-form.It was only after the horrors of Hive Fleet Behemoth and Hive Fleet Leviathan's invasions that the Imperium came to realise their true purpose as highly advanced infiltrators for the Hive Mind of the most insidious kind. Hiding away on voidships and in the depths of space hulks, the Genestealer menace has travelled across the length and breadth of the Imperium, seeding themselves onto Human-settled worlds and subverting their populations.This perhaps is the greatest horror the Genestealers bring, as they can infect almost any lifeform with a "kiss," implanting some of their own Tyranid genetic material into the host and taking complete control of its reproductive system. When the host subsequently gives birth to offspring, these carry with them the Genestealer's genes and over the course of several generations a new Purestrain Genestealer is born, albeit with some genetic traits taken from its host species: such as the Human-like hands many Genestealer hybrids encountered in the Imperium possess.Cunning and independent, Genestealers are also one of the few Tyranid bioforms that can exist away from the nurturing and controlling influence of the Hive Mind, using their own innate intelligence and brood telepathy to form tight-knit groups.These groups can survive for solar decades or even Terran centuries on worlds, hiding their presence and infecting more and more of the population until the time to strike arrives, usually coinciding with the arrival of a hive fleet and the wholesale invasion and consumption of the world by the Great Devourer.
Genestealer - Reproduction Cycle: Genestealers reproduce by introducing their genetic material into a host from another intelligent species; this is normally a Human, but can theoretically be any sentient humanoid species, including the Aeldari or the Orks.The Genestealers have no true genders, and require another creature of any species, of any gender, to reproduce. The Genestealer will find a suitable host and hypnotise them into passivity using a psychic effect induced with its eyes. The Genestealer then thrusts its long, whip-like tongue (which also serves as an ovipositor) into the body of the host, where it deposits its DNA in the form of a type of virus that infects the somatic and germ line cells of the host.Several solar hours later, the infected victim wakes up from the incident, with no wounds or any recollection of what happened. The new host of the Genestealer DNA will go on about their normal life, and eventually reproduce with another member of their species, thus siring or giving birth to a Genestealer hybrid.The Genestealer reproductive cycle is truly cyclical, as a fourth generation hybrid will always spawn a Purestrain Genestealer in the fifth generation with a genome identical to that of the original Genestealer that infected the first host.Newly-born Genestealer hybrids, although fundamentally Genestealers, will have characteristics inherited from the host parent. Thus a Genestealer hybrid of Human stock may have a vaguely humanoid head, or only two arms instead of the usual four, and its tail will be shortened or missing. A Genestealer hybrid of four or more generations of consistent Human parentage would pass for a baseline Human on cursory inspection, although a closer look would reveal bluish skin, sharp, pointed teeth and unsettling behaviours.The Ymgarl Genestealers on their homeworld exploited a large, semisentient leech-like creature called a Csith as their usual host, which explains their variant and more inhuman appearance. As a known exception to the normal Genestealer reproductive cycle, Csith hosts always produce natural, full-blooded Purestrain Ymgarl Genestealers rather than hybrids, no matter what the parentage of previous generations.
Genestealer - Purii: A full Purestrain Genestealer starts the infection cycle by inserting their genetic material into a host victim. As the infestation spreads and its newborn Genestealer Cult grows, the first Genestealer takes on the role of a Genestealer Patriarch and often grows larger into an obese and potently psychic monstrosity.
Genestealer - The Infected - Contagii: The host victims, or Contagii, return to their own societies and begin to have an urgent need to find a mate and begin a family. This mate also becomes infected with Genestealer DNA through sexual intercourse with the infected host.Contagii, many of whom become Brood Brothers, still physically and metabolically resemble other members of their species, though they may have a slight blue or mauve pallor to their skin and can be psychically controlled by the Genestealer Patriarch who infected them through the Broodmind to become mindless slaves, making them the perfect infiltrators.The psychic control of the Genestealer's Kiss can be resisted by infected Space Marines, as seen with members of the Scythes of the Emperor. However even they wear psychic dampening hoods to keep out the Broodmind's urgings.
Genestealer - Generation 1 - Maelignaci: The first of a Genestealer Cult's vile Genestealer hybrid children, a First Generation Hybrid or Maelignaci is as much of a monster as it looks. More reminiscent of a Genestealer than a Human, these foul creatures feature between five or six limbs, each one ending in sharp talons. These mutants often serve as Acolyte Hybrids.Their bulbous heads have the facial features of their xenos gene-father, with their skin taking on a purple hue. These creatures are little more than beasts, their instincts directing their every move.
Genestealer - Generation 2 - Hybrid: The second generation of Genestealer hybrids are hunched and stooped -- not in the manner of the old or infirm, but more like pressured springs, ready to explode into movement. Like the generation before them, Second Generation Hybrids, who also serve as Acolyte Hybrids, may have five or six limbs, but their eyes and mouth are more like their Human parents, and they can make themselves understood in Low Gothic.Though their minds are still so alien that they defy analysis, they are still sapient enough to understand their host society. Some are even put to work in the industrial brotherhoods of their kin, their uncanny strength and resilience allowing them to use heavy mining tools and explosives with far more ease than any mere Human.
Genestealer - Generation 3 - True Hybrid: Taking a fully upright stance, the Third Generation Hybrid is reminiscent of many mutants in Imperial society. Their foul features go unnoticed in the underhives of many Imperial worlds. However, on closer inspection their alien form is revealed. They have heavily ridged heads, mauve to violet skin, and may even hide an extra clawed limb under their tattered clothes.True Hybrids often become Kelermorphs and Loci.
Genestealer - Generation 4 - Primacii: By the fourth generation of Genestealer hybridisation, the scions of the Genestealer Cult can pass for fully Human, inveigling themselves into positions of power to further the aims of their sinister cult. Most of these Primacii serve as Neophyte Hybrids.A few members of this generation possess psychic powers and become a Magus or Genestealer Primus. Other types of Fourth Generation Hybrids include Clamavi, Nexoses, Sancti, and Biophagi.They are often noted by their Human overseers as dutiful, hard-working Imperial citizens, and as such, usually find themselves above suspicion. Many of these hybrids join the Astra Militarum to spread their vile seed across the galaxy, starting new cults and claiming worlds for their four-armed Genestealer Patriarch.Between the fourth and fifth generations of hybrids, the Genestealer Cult will prepare for all-out war. They will spawn Hybrid Metamorphs, creatures that echo the warrior bioforms of the true Tyranid hive fleets and are built only to serve as vicious cannon fodder for the coming battles.
Genestealer - Generation 5 - Purii: Paradoxically, the Genestealer's purestrain DNA reemerges in the fifth generation of Genestealer hybrids since the initial infection, giving birth to a fully Tyranid Purestrain Genestealer, albeit one showing some physical characteristics of the original host species.Thus the cycle can begin anew, as the new Purestrain Genestealers have the potential to infiltrate other worlds and become a Genestealer Patriarch.
Genestealer - Other Host Species: The Purestrain Genestealer can, through the modus of implantation via its ovipositor, place its germ-seed in any creature of the requisite anatomy to later sire a Genestealer hybrid. Over the countless centuries since their introduction into the stellar realm of Mankind, these extragalactic predators have started colonies within the species of the Orks, the Greet, the Kroot, the Vespid, the Aeldari, the Tarellian, and even the T'au.They tend to choose ambulatory humanoid species of sufficient intellect to be space-capable, and hence spread their curse far and wide, and will usually target one whose population is dense enough to keep such a spread secret until it is too late for the infection to be overcome.The Orks have proven troublesome as Genestealer hosts, for they can sense a wrongness in those infected, something that disturbs the strange gestalt of the Greenskin mind. The Kroot are much the same, though their avoidance of infected members of their society comes from their ability to taste pheromones, and the wisdom of the Kroot Shapers who guide their people's evolution.The Aeldari have such lengthy gestation cycles that they are simply not viable biological hosts; furthermore, their psychic abilities are so well developed they can often see the shadow of the Genestealer's genetic curse on the infected even before it can manifest, and avoid it accordingly.The T'au have a connection with their Ethereal Caste that makes infection by the Genestealers difficult. Only Humanity, so manifold and unruly in its civilisations, has as yet provided an ideal host.
