[From Imperium Maledictum]
Wherever you were born, you don’t remember it. You are Progena, an orphan whose parents died in service to the Imperium. You were brought to a Schola Progenium, one of many orphanages run by the Ecclesiarchy on various worlds of the Imperium, all designed to create the ideal servants of the God-Emperor of Mankind. "Your memories of life before the schola were wiped from your consciousness, leaving you a blank slate, clay to be moulded" into an uncompromising leader, a dauntless warrior, a zealous preacher — whatever the Imperium needed most. Your early years were an unyieldingly severe regime of religious indoctrination, physical conditioning, and exacting education. You emerged from the schola a "disciplined exemplar" of the Imperial Creed, ready to excel in His name.
