Primarchs
The primarchs were the 20 genetically-engineered transhuman “sons” of the Emperor of Mankind created in the late 30th Millennium. They were intended to be the immortal and superhuman generals and proconsuls who would command the Emperor’s Great Crusade to reunite the scattered Human race beneath His leadership. Their genomes later served as the genetic templates from which the Emperor crafted His 20 Space Marine Legions.
