Space Marines - Primaris Space Marines: The Primaris Space Marines are a new breed of transhuman warriors developed across the span of ten thousand standard years by Archmagos Dominus Belisarius Cawl on Mars on the order of Primarch Roboute Guilliman.Cawl used the genetic template of the original Space Marines created by the Emperor for His Great Crusade as the starting point for the development of the new Astartes soon after the Second Founding in the early 31st Millennium. Primaris Space Marines are bigger, more physically powerful and possess faster reaction times than their original Astartes counterparts.For ten millennia, Archmagos Dominus Belisarius Cawl has been working on a task set for him by the Primarch Roboute Guilliman before he was mortally wounded by the Daemon Primarch Fulgrim in the days after the Horus Heresy: a new legion of transhuman warriors.Developed on orders from Guilliman 100 standard centuries past, Primaris Space Marines were diligently developed and perfected by the Priesthood of Mars during the long intervening millennia.As an optimist, but never a fool, Guilliman learned from the mistakes of the Horus Heresy, and he foresaw that the forces of Chaos would never relent in their aim to bring the Imperium low.He anticipated that devastating times would once again engulf the galaxy and knew that warriors resilient enough to stand against them would be needed as never before. That time has surely come. Now, as the Imperium of Man is poised on the brink of annihilation at the hands of Chaos, his task is at last complete.The Primaris Space Marine is a new generation of hero for this, the darkest age in the Imperium's history. These warriors are the next step in the evolution of the Emperor's Angels of Death -- genetically altered from their brethren, now called the "Firstborn," to be bigger, stronger and faster -- timely reinforcements for the Imperium's armies as their enemies close in for the kill in the wake of Abaddon the Despoiler's 13th Black Crusade and the birth of the Great Rift dividing the Imperium in two.To aid them in battle, these gene-forged warriors are equipped with new arms and armour forged on Mars itself, such as the Mark X Tacticus Pattern Power Armour worn by the Primaris Space Marine Intercessors, which combines the most effective elements of ancestral Horus Heresy patterns of battle-plate with more recent developments in power armour technology.They are outfitted with the Mark II Cawl Pattern Bolt Rifle, the archetypal firearm of the Adeptus Astartes, now re-engineered, re-crafted and perfected; the Mark III Belisarius Pattern Plasma Incinerator, a new refined Plasma Gun; Redemptor Dreadnoughts, the Overlord gunship, and Repulsor grav-tanks.At the dawn of the Indomitus Crusade to retake the Imperium from the advancing armies of Chaos and xenos alike, Lord Commander of the Imperium Roboute Guilliman has gathered his new armada, along with elements of the Adeptus Custodes, a small contingent of the Silent Sisterhood and a vast war host of Primaris Space Marines as he fights to liberate the scattered bastions of the Imperium.Some, Guilliman has forged into new Space Marine Chapters, whole brotherhoods comprised only of these new transhuman warriors. Others he has offered to the existing Firstborn Space Marine Chapters.Many Firstborn Chapter Masters have welcomed their Primaris brethren into their ranks, accepting the new reinforcements gladly. Others, though, view these new creations with suspicion or outright hostility, claiming that the Emperor's work should never have been meddled with by mere mortals.The newly reinstated Lord Commander of the Imperium decreed that those Chapters most devastated by the ongoing wars would be amongst the first to be reinforced with this new breed of transhuman warrior. Starting with the Ultramarines, but also deploying these new Space Marines to every other Chapter in need, Guilliman aimed to reinforce the Imperium's scattered defenders across the galaxy.It is not just as reinforcements to existing Chapters though. Guilliman also ordered the creation of a host of new Chapters, the so-called "Ultima Founding," composed entirely of Primaris Space Marines.The warriors of these new Chapters were created entirely using the new processes discovered by Archmagos Belisarius Cawl and established with all the necessary weapons, armour and equipment that they will need to conduct their defence of the Imperium.These Chapters still trace their genetic lineage back to the gene-seed of the First Founding, and scions of all nine Loyalist Space Marine Legions emerged from the stasis vaults beneath the Red Planet.They benefit from three additional gene-seed organs, larger size, better reflexes, and greater resiliency, but it still remains to be seen if Cawl was able to successfully stabilise any of the known genetic deviations or impart any additional resistance to the effects of Chaos.Many of these new Chapters have been assigned homeworlds on the edge of the Great Rift, the Imperium's new frontline in the war against Chaos, though some have inherited the empty fortress-monasteries of Chapters that had been lost to the attrition of constant war.Many of these worlds face a continuous battle against the daemons of the Warp, as well as an unpredictable mix of xenos raiders, pirates and invaders.Though they are a step removed from their Firstborn brothers, the Primaris Space Marines still bear the gene-seed of their primarchs, and some dissenting voices worry how this new type of warrior will react with the known genetic quirks and flaws of some of the more unusual Chapters, such as the Blood Angels and the Space Wolves.The Primaris Space Marines offer new hope to a besieged Imperium, but the future remains a dark and uncertain place.
