Adeptus Arbites - Adepta Organisation: The overall leader of the Adeptus Arbites is the Grand Provost Marshal, who represents the Arbitrators on the Senatorum Imperialis as one of the High Lords of Terra. Below the Grand Provost Marshal are the senior Arbites officers known as the "Marshals of the Court" who oversee sector-spanning administrative jurisdictions that are called "Precincts."Below the Marshals of the Court, the Arbites are internally divided into two primary divisions; the Judges, who deal with actual legal matters and the application of ten thousand standard years of Imperial Law to criminal and civil cases, and Arbitrators, the paramilitary law enforcement arm of the Arbites who perform the work necessary to apprehend and punish those who break the dictates of the Lex Imperialis.Arbitrators and Judges operate in parallel organisations within the Adeptus Arbites, though the two separate organisations join at the highest ranks when senior Judges and Arbitrators are raised to become Marshals of the Court. Senior Arbites fulfill both roles, with Judges getting their hands dirty apprehending criminals in the field, and Arbitrators learning to preside over lengthy court trials.There are numerous ranks and roles within each of the Arbites divisions, such as the squads of Verispex technicians who provide forensic evidence drawn from a crime scene to the Judges and Arbitrators, the Chaplains who provide the spiritual sustenance of the Imperial Cult to the Arbitrators and the Chasteners who are experts in the psychological and physical interrogation of prisoners.For their part, the Arbitrators are divided into many different functional roles, each trained and equipped accordingly. Patrol groups of Arbitrators prowl the dangerous underhives of hive cities, Shock Troops break up the vicious queue wars which often develop outside Imperial government buildings belonging to the bureaucrats of the Administratum, Execution Teams hound the guilty through barren wastes and labyrinthine tunnels, and Snatch Squads apprehend targets for interrogation by the Chasteners.Other kinds of Arbitrators include cyber-warfare specialists who apprehend cyber-criminals through the cogitator matrices of the Administratum and specialists who carry out more long-term investigations who are known as Arbitrator Detectives. Senior Arbitrators are often awarded the rank of Proctor and placed in command of the different types of Arbitrator squad.Arbites installations are maintained on almost every Imperial world and are known as precinct-fortresses or precinct courthouses. Each precinct courthouse includes an armoured installation that serves as an armoury, training ground, barracks, prison and judgment hall.In order to remain fully aloof and separate from the populations they patrol, precincts are as close to fully-enclosed and fortified cities as they can be, and include dungeons, barracks, firing ranges, scriptories, archives, warehouses, kitchens, gymnasia and garages. They include all possible resources that the Arbitrators require -- including their own Astropath facilities and access to orbital docks. These courthouses are intended to be self-sufficient and to support a complete Arbites army and they are equipped as such.Amongst the most highly trained and disciplined individuals in the Imperium, Arbitrators may find themselves commissioned to join the retinue of an Inquisitor as an Inquisitorial Acolyte.The Arbites has strong ties in particular with the Ordo Hereticus, and the two can often be found working towards common goals. Arbitrators in these retinues are ironically often known as "Enforcers," having been released from their single-world jurisdiction, and free to punish law-breakers wherever they may be.
