Hidden from all but the most powerful figures of the Imperium, the Officio Assassinorum trains and unleashes the deadliest killers Mankind has ever produced. Its operatives are drawn from the young and gifted, then remade through decades of gene-craft, surgery, and hypno-conditioning until nothing remains but the perfect instrument of death.
The Officio is organised into distinct Temples, each a self-contained world of ritual and secrecy devoted to a single discipline. The marksmen of one Temple can slay a target across a battlefield with a single round. The shapeshifters of another walk unseen among the enemy, wearing stolen faces to strike from within. Others produce frenzied berserkers or soulless anti-psykers, each a nightmare tailored to a different kind of prey.
An execution sanctioned at the highest level sets these weapons loose. Once an Assassin is committed to a kill, it will pursue its quarry to the ends of the galaxy, patient, relentless, and utterly without mercy. To be marked by the Officio Assassinorum is, for almost all who suffer it, a death sentence already carried out.
Imperial Agents
Order of battle
The Officio Assassinorum field the units of the Imperial Agents — a detachment from the roster:
Kindred formations
Other Imperial Agents formations
Adeptus ArbitesThe Imperium's iron-handed galactic lawmen, judge, jury and executioner in a single armoured figure, upholding the Lex Imperialis across ten thousand worlds.
Imperial NavyThe vast star-fleets of the Navis Imperialis, kilometres-long warships that rule the void, escort the Emperor's armies and bind the Imperium's worlds together.
Rogue TradersPrivateer-explorers bearing the ancient Warrant of Trade, licensed to trade, conquer and treat with aliens beyond the Imperium's edge in the Emperor's name.
Sisters of SilenceThe Sisters of Silence are an ancient order of soulless women, warriors whose very presence is poison to psykers and daemons alike. Born as Untouchables, they render their oaths without a single word, wielding flame and blade alongside an aura of null that smothers sorcery. They serve as jailers and executioners of the Imperium's most dangerous witches, and their arrival heralds the hunt for a psyker of terrible power.
The InquisitionThe Inquisition is the Imperium's ultimate authority, a shadowed order that answers to none save the Golden Throne. Its Inquisitors hunt heresy, daemon, and alien alike, wielding the power to command fleets, judge worlds, and condemn the corrupt to fire. Divided among great Ordos, each dedicated to a different existential threat, its members walk a razor's edge between salvation and damnation in defence of Mankind.
