on the loose and the enigmatic Eldar taking an interest in a world that was once theirs, the players are presented with a dire situation with no obvious hope for success. Characters Player characters are usually represented in-game by 54 mm miniatures purchased from Games Workshop, roughly twice as large as the standard 28 mm Heroic scale of WH40K miniatures. The models available represent existing characters (such as Witch-hunter Tyrus, or Inquisitor Eisenhorn) presented in the rulebook. Players wishing to depict their own unique characters are generally required to extensively convert their models, or give them unique paint schemes. However, the distances given in the rulebook are written as yards, so that players can use any scale of miniature they wish, including the same models with which they play standard Warhammer 40,000. There are many different groups that players can play. Presented here are the archetypes represented in the Rulebook: The titular Inquisition: An order that operates as a secret police of the Imperium, charged with rooting out threats to mankind from both within and without, and granted absolute authority in its mission to do so. The Adeptus Astartes: They are the "Space Marines," a legion of warriors that serves the Emperor of Mankind, being genetically enhanced supersoldiers, fanatically devoted to the cause of the Imperium. The Adeptus Mechanicus: The engineers of the Imperium, focused primarily on technology and research. Rogue Traders: Bands of merchant-adventurers or similar people, whose allegiance may vary. Cultists and Fanatics: Street preachers and zealots who mostly serve the Ecclesiarchy and worship the Emperor of Mankind. The Imperial Guard: The primary military force of the Imperium - unlike the Adeptus Astartes, they are most often normal human beings. Desperados: Gunslinging rogues akin to Rogue Traders, their allegiance may vary. The Enforcers: They serve the Imperium but may also operate as independent/rogue groups under the command of a disloyal commander of an individual ruler of a world. Mutants: Mutants are humans either warped by the power of Chaos or mutated due to genetic deviancy. They are hunted down by those Inquisitors who deem any mutation as a threat against humanity and the Imperium. The Ecclesiarchy: The religious organisation of the Imperium, officially known as the Adeptus Ministorum, they maintain and spread the worship of the Emperor of Mankind. Arco-Flagellants: Heretics deemed by the Ecclesiarchy only able to gain redemption through their use as mindless living weapons against
