Primaris Space Marines

"They were forged for Mankind's darkest hour - and that hour is upon us."

- Roboute Guilliman

Primaris Space Marines are a new breed of super-human warriors, developed for ten millennia by Archmagos Belisarius Cawl in Mars (at the orders of Primarch Roboute Guilliman) from the Space Marines created by the Emperor for His Great Crusade.

Overview
For ten millennia, Archmagos Dominus Belisarius Cawl has been working on a task set for him by the Primarch Roboute Guilliman: a new legion of warriors. Now, though the Imperium is poised on the brink of annihilation, his task is complete.

The Primaris Space Marine is a new breed of hero for this, the darkest age in the Imperium’s history. These new warriors are the next step in the evolution of the Emperor’s Angels of Death – genetically altered from their brethren to be bigger, stronger and faster – timely reinforcements to the Imperium’s armies as their enemies close in for the kill.

To aid them in battle, these new gene-forged warriors are equipped with new arms and armour forged on holy Mars itself, such as the Mk X Tacticus Power Armour worn by Intercessors (a suit that combines the most effective elements of ancestral Horus Heresy patterns of plate with more recent developments in power armour technology), Mk II Cawl-pattern Bolter (the archetypal firearm of Space Marines, re-engineered, re-crafted and perfected), and Redemptor Dreadnoughts.

At the dawn of the Indomitus Crusade, these phenomenal new warriors join Guilliman 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 warriors. Others he has offered to the existing Space Marine Chapters. Many 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 not have been meddled with.

Though they are a step removed from their 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.
