40K: Dead Cabal of Spite
“…the Inquisition merely performs the duty of its office. To further fear them is redundant, to hate them, heretical. Those more sensible will place responsibility with those who forced their hands…”
— Captain Gabriel Angelos of the Blood Ravens Space Marine Chapter after the Inquisition’s Exterminatus of Typhon Primaris
The Inquisition (The Holy Orders of the Emperor’s Inquisition) is a secret organisation that exists outside the standard administrative hierarchy of the Imperium of Man. The Inquisition acts as the secret police force of the Imperium, hunting down any and all of the myriad threats to the stability of the God-Emperor’s realm, from the corruption caused by the Forces of Chaos, Heretics, mutants and rebels, to assaults from vicious alien species like the Tyranids, Orks or Dark Eldar. The Inquisition’s infamous sigil was derived from the personal heraldry of Malcador the Sigillite, the Regent of Terra during the Great Crusade and the Horus Heresy and the second most powerful psyker in the Imperium of Man after the Emperor of Mankind himself. It was Malcador who first created the secret organisation that would later become the varied Ordos of the Inquisition at the start of the Heresy on the orders of the Emperor. The Master of Mankind had ordered the Sigillite to find a group of men and women of an “inquisitive nature” to search out the enemies of the Imperium, whether they lay within or without.
