“I have stood within the palace of the Throne on Holy Terra itself. There my soul was shattered and re-formed, a living weapon forged on the Emperor’s will.”
— Primary Psyker Thassail Kain
These psykers are individuals deemed strong enough to serve the Imperium without significant dangers to others. These psykers serve in many parts of the Empire of Man, nominally as vassals to the Adeptus Astra Telepathica; from the Administratum to the Imperial military, within merchant houses or even for planetary governors. Imperial psykers often blend into their seconded post with surprising skill. Clad in monkish robes or secure behind scholarly titles, they often appear indistinguishable from the vast ranks of Administratum scribes. That is, until they must call upon their eldritch powers. Others serve within carefully constructed roles such as the Savant Militant of the Imperial Guard. Sanctioned psykers follow various schools of training, known collectively as the Scholastia Psykana. Much like the Imperial Creed, the exact teachings of the Scholastia Psykana may vary from sector to sector (or even planet to planet) yet the intent remains the same---training dutiful psykers to serve the Imperium.
