Cybertheurgy

"The beast of metal endures longer than the flesh of men. Those that tend the beast of metal must labour long to learn its ways, for a single beast must suffer the mastership of many men until ready to shed its last vorpal coils."

- Introit to Runic Mechanics

Cybertheurgy are the ancient arts from the Dark Age of Technology utilised exclusively by the Magos Dominus of the Legio Cybernetica to fashion and maintain a small, but powerful, cadre of Battle-Automata for the Imperium. This archaic knowledge hails from a time when the un-living phalanxes of Mankind's creations shattered forgotten alien empires to carve humanity's first empire from the stars. Although much of this lore had been lost or become expressly forbidden (most notably through the institution of the Crimson Accords) by the time of the Great Crusade, enough fragments of this knowledge existed and was utilised in the formation of the Legio Cybernetica, one of the most feared and powerful of the Legiones Militant of the Mechanicum. The use of Cybertheurgy allowed for the Legio Cybernetica's Magos to control those robotic engines designed for warfare and slaughter - the Imperial Robots. Such is the nature of the dark arcana of Cybertheurgy, however, it is not without its risks, as what is awakened may slip the leash of its master's control with disastrous consequences.
