Inquisition

The Inquisition, formally called 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 Drukhari. 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. The Inquisition is divided into three major orders or "Ordos Majoris" in High Gothic and many other minor ones, or "Ordos Minoris," each dedicated to confronting a very specific threat to the continued survival of the Imperium and Humanity.
