„There are no depths which we may fly above, no chasm we may bridge. It is our duty to fall into the pits, and there drag the unworthy before Judgement.”
–Arbitrator Linger

The Calixis Sector is plagued with heretics, recidivists, and the unworthy…and they all dwell beneath the faithful servants of the God-Emperor, eroding the backbone of the Imperium’s war machine. Whether it is a planetary noble skimming off the top, or a seditious terrorist planning the destruction of an entire Hab-block, it is the Adeptus Arbites who bring them to judgement.

„Book of Judgement” is a guide to crime and punishment in the Calixis Sector, and provides a powerful resource for Dark Heresy campaigns that feature Imperial Law as a story foundation. This detailed supplement contains new rules, backgrounds, alternate careers, and equipment for playing Acolytes with legal authority or a criminal past, and provides players with information about the Adeptus Arbites’ mission to bring order to the Calixis Sector. Game Masters of all experience levels will find expanded Investigation rules and a new adventure, Jurisdiction, that plunges the Acolytes into a conflict between three of the Imperium’s most powerful organisations.
