The Emperor had already been fighting on [[Terra]] with [[Thunder Warriors|genetically modified warriors]], but in the end they proved hyper-violent and short-lived. This project would be his greatest attempt to create generals to lead these warriors, second only to himself in skill, ability, and sheer power. It was begun in [[M29]] with the aim to create 20 cloned 'children' of the Emperor. The facility to create these [[Primarch]]s was constructed on [[LunaTerra]] and the Emperor alongside the [[Perpetual]] [[Erda]]{{Fn|7}} and [[Biotechnical Division]] Director [[Amar Astarte]]{{Fn|6}} oversaw the project, having them grown in accelerated gene culturing chambers. His scientists watched over the growing fetuses in their chambers, afraid of what would happen if anything went wrong. According to [[Perturabo]], his date of birth was around 792.[[M30]], perhaps giving a date for the birth of the Primarch's.{{Fn|6}}

The Emperor could sense that the infant Primarchs were alive, but was unable to reach them. Therefore , he used their previously collected DNA samples to create the [[Space Marine]]s. The genetic material of each one of the Primarchs was used to found a single [[Space Marine Legion]], twenty in total. The new homeworlds of the infant Primarchs and subsequent experiences on those worlds would influence and mold them to a large extent. There they quickly grew to adulthood and often rose to power, ruling, leading, and helping the inhabitants. As the Emperor found them, he was generally pleased by their actions, and quickly gave them the leadership of their respective legionlegions.{{cite thisFn|9}} Amar Astarte came to believe that the Primarch Project and indeed the whole of the Legiones Astartes was doomed. The Primarchs were the key anchor to maintaining the genetic stability of the Space Marines, and upon their scattering she saw the entire enterprise as a failure. This eventually led her to try to destroy the genetic knowledge behind their creation in the [[Palace Coup]].{{Fn|6}} ==See also==*[[Prototype Legionary]]*[[Thunder Warriors]]
