The Schola Progenia are academies run by Missionaries of the Ecclesiarchy. These schools teach and train orphans of Imperial officials who have given their lives in the service of the Emperor of Mankind. These orphans are indoctrinated into the Imperial Cult from an early age, and soon learn to regard the Emperor as their spiritual father.
Graduates of the Schola are known as Progena, and because of the loyalty their training has instilled in them, graduates are sent for further training and service within other Imperial organizations, often earmarked for roles that call for the most rigorous dedication to the Imperium, whether these are the Storm Troopers and Commissars of the Imperial Guard, officers of the Imperial Navy, Imperial Assassins, or sometimes budding Inquisitors. Female progena often join one of the Orders of the Adepta Sororitas.
