====Birth====

The [[Unification Wars (Hektor Heresy)|Unification Wars]] taught a great many lessons to the Emperor of Mankind. He saw the brutal efficiency of his genetically enhanced Thunder Warriors, who took impregnable fortresses like cardboard castles and routed innumerable technobarbarian hosts without breaking into a sweat. But he also saw their dangerous instability, both mental and physiological, their insatiable craving for violence and destruction and their propensity to genetic diseases. As good as these warriors were, they weren't suited for conquering the Galaxy. It was then that the Emperor decided to create a superior breed of superhumans by stabilising the genome of the Thunder Warriors, trading off some of their destructive potential for stability and longevity. Thus began the Primarch Project.

With the assistance of his best genewright [[Ataulf Sachs]], the Emperor set about tweaking the Thunder Warrior genes, striving to create a subspecies of humans that would combine the might of his supersoldiers with calmness and clarity of mind. It took him several failed experiments to approach this bold goal, and yet the first real Primarch he created could not be considered a complete success. There was still a lot left in him from the Thunder Warriors, he was more of a missing link between the two species than a proper Astartes. A rigorous genetic purist, Sachs insisted on destroying the boy as a failed experiment, but the Emperor ruled differently. He saw that even a deeply flawed Primarch like that could have his uses in the Great Crusade, and so the boy was saved.

Saved, but not for very long! The forces of Chaos eventually learned of the Primarch Project and hatched a plan to stop it at all costs, or at least twist it so much that it would serve their own purposes. While the Emperor was away, the Dark Gods snatched the capsules housing the infant Primarchs from his geneforge and scattered them throughout the Galaxy. Some of the Primarchs landed on peaceful and civilised worlds, some on inhospitable planets ruled by savagery. Neolithus was certainly one of the latter.
