Imperial Law

Main Page | Imperial Law


Imperial Law focuses on tithes, religion, loyalty and heretics. It’s difficult to find an actual summary of what it contains so I’ve written some guidelines below. These laws apply to everyone in the Imperium (except Inquisitors and their agents).

Section numbers are for flavour. The book itself represents a condensed version of the most commonly required or key laws. The full law – the Lex Imperialis – is held on Terra in countless tomes that are continually updated by the Lords of Terra.

  • Section IV C (4c): Tithes
  • Section VII A (7a): Levy
  • Section VIII D (8d): Rebellion against the appointed authority
  • Section XXI B (21b): Heresy
  • Section XXV E (25e): Respect and protect agents of the Imperium
  • Section XXXIV C (34c): Ignorance is purity
  • Section XLII D (42d): Technology
  • Section L C (50c): Withholding artifacts and information
  • Section LXIII D (63d): Every human is an Imperial citizen
  • Addendum: The Inquisition
  • Section IV C (4c): Tithes

The tithes and the taxes keep the forces of the Imperium clothed and fed. Avoiding the tithes and taxes, misrepresenting wealth and profiteering are illegal.

  • Section VII A (7a): Levy

The levy of psykers is vital to keep the Emperor alive, the navigators steering ships, and to enable interstellar communication. Psykers must be made known to the authorities for transfer to the league of black ships of the Adeptus Astra Telepathica. The black ships only arrive every century, so in the mean time the threat they pose must be monitored and dealt with where necessary. Harboring or aiding a rogue psyker is illegal.

  • Section VIII D (8d): Rebellion against the appointed authority

Mutiny and unrest against the appointed authority causes inefficiency and doubt, and forms the seeds of heresy. Ring leaders must be dealt with, and failed figures of authority dealt with. Disobeying rightful orders from agents of the Imperium, such as commissars or the inquisition, is illegal.

  • Section XXI B (21b): Heresy

Denying the divinity of the God-Emperor of Mankind is heresy. Worshiping any other god is heresy. Promoting unsanctioned cults is heresy. Permitting mutants to breed or spread their corruption is heresy. Suffering the alien, the artificial or the daemon to live is heresy. Heresy is illegal.

  • Section XXV E (25e): Respect and protect agents of the Imperium

Some servants of the Emperor are more vital than others. Agents of the Adeptus Terra must be protected and assisted where possible. Of particular note are the rare and precious Navis Nobilitae – the mutant nobles whose insight into the warp enable rapid interstellar travel. The Adeptus Mechanicus, the rogue trader families, the ecclesiarchy and the inquisition must be dealt with with utmost respect. Summary executions may never be performed on the navis nobilitae. Summary executions may only be performed on members of the inquisition, members of a rogue trader family, the ecclesiarchy and the adeptus mechanicus in the face of dire, lethal and extreme heresy. Where members of these organisations break the law they are to be handed over to their organisations for judgement wherever possible. Failing to aid and protect vital agents of the Imperium is illegal.

  • Section XXXIV C (34c): Ignorance is purity

Pursuing knowledge for its own sake is dangerous. Some lore is so dangerous that it is forbidden. Those who pursue it, learn it or share it without sanction are encouraging heresy and endangering Imperial citizens. Forbidden knowledge is illegal.

  • Section XLII D (42d): Technology

Interfering in technology without the express permission of a Tech Priest of the Adeptus Mechanica offends the machine spirit of that artifact and in turn the Emperor in his guise of the Machine God. A machine spirit must be wooed with the correct rituals and prayers. Attempting to use or preserve the foul technology of the alien is heresy. Attempting to alter or clone humans, or create intelligence artificially is to corrupt humanity. Meddling in technology is illegal.

  • Section L C (50c): Withholding artifacts and information

Withholding rare or unusual artifacts from the Imperium where they can be properly judged and researched endangers citizens, and may inhibit technological rediscovery. Withholding information about threats to the Imperium is often deadly. Discoveries must be tithed to the Imperium as soon as possible, failure to do so is illegal.

  • Section LXIII D (63d): Every human is an Imperial citizen

Every human and every human colony must be brought into the fold of the Imperium as soon as possible that they may know the light of the God-Emperor and begin tithing. Any attempt to break from the Imperium, or hide humans from the Imperium is illegal.

  • Addendum: The Inquisition

The Inquisition and its agents are the only people in the Imperium above the law. Concern about the behaviour of an inquisitorial agent may be brought to the inquisitor they serve. Questioning the behaviour of an inquisitor is illegal.
