The Primaris Founding

The Primaris Founding, or referred to as the "First Founding" of the Imperial Marine Legions, also titled the Legiones Imperialis, occurred in the middling days of the 90th Millennium in the year M90.474 after the end of the Dark Ages of the Long Dark and during the waning years of the Terran Unification Wars that founded the Stellar Imperium upon Terra.
The firstborn Eight Imperial Marine Legions, along with the subsequent Parousian and Trichotomic Foundings were created from the Inheritance-Helix clusters of the 20 superhuman Luminarchs engineered by the Emperor of Mankind from His own genetic code in His gene-laboratories beneath the Imperial Palace on Terra in the Kilaminjanto (Kilamanjaro) Ranges.
In spite of the fact that the gestalt Luminarchs were still in their pre-embryonic stages, the Emperor still waged his Unification Wars of Terra and later the reclamation Wars of Sol—and to these ends He managed to forge complete and viable samples of each Luminarch's DNA—at least prior to their scattering and subsequent far-flung births.
The Emperor used the First Eight of these templates to create the first generation of eight Imperial Marine Legions by genetically enhancing His own Terran-born soldiers with the Inheritance-Helix derived from the genomes of the first eight Luminarchs. The Imperial Marine Legions born of this process were tutored by the still surviving Veterans of The I'cartes Regiments and subsequentely utilized to complete the Unification Wars upon Terra, forging the iron hold and cleansing terra of all elements that would undermine the Empire so many had already died to create.
With each Luminarch the Emperor re-discovered during the course of the Great Crusade, He gave command of the Imperial Marine Legion created from their genetic material back to them. Each Luminarch then set up their Legion's headquarters on his/her own homeworld, from which they also recruited new Imperial Marines into the Legion.
