Calixis Sector - Adeptus Arbites: The role of the arbitrators is to ensure that the Calixis Sector's worlds obey Imperial law. Most worlds have an Adeptus Arbites presence and the arbitrators tend to be based in grim, precinct-fortresses to remind the population of the unyielding nature of Imperial law and to insure that there will always be a defendable location for the Arbites to hold in case of widespread rebellion.In the Calixis Sector few worlds aside from Scintilla have a major arbitrator presence, and most worlds only have a single precinct-fortress along with a few regional stations. In spite of this, the arbitrators are a feared force because they are loyal to nothing save Imperial law. Even a planetary governor can be arrested by the Adeptus Arbites should they harbour the Emperor's enemies or seek to throw off the yoke of Imperial authority. While they are a formidable presence with great authority, the arbitrators can only act to defend Imperial law and have little influence beyond this.Lord Marshal Luthir Veremonn Goreman is the most senior arbitrator in the Calixis Sector. Goreman began his long career as a local planetary Enforcer, and his lack of sympathy for the desperate mass of Imperial citizens borders on disdain. He sees no greater crime than that of an Imperial citizen abandoning their duties to take up arms against a rightful authority, and he is known to personally lead riot suppression forces on Scintilla.The Lord Marshal demands regular reports from arbitrators on the sector's other planets, and is pessimistic in character, constantly issuing dire warnings about the Calixis Sector careering down a slippery slope towards lawlessness and terror. Goreman sees doom and anarchy in everything, including the activities of Scintilla's corps of Enforcers, the Magistratum. As far as he is concerned, the Magistratum are part of the problem and he actively despises them.Goreman has recently permitted the development of the Divisio Immoralis, a small taskforce of arbitrators whose purpose is to collect intelligence on cult activities across the Calixis Sector and explain a recent rise in unrest and acts of terrorism by fringe cults. The Divisio Immoralis numbers only a few arbitrators led by the veteran, and rather burned-out, Senior Arbitrator Kae Drusil, but they have considerable leeway for their investigations and may turn up anywhere in the sector.On Scintilla, the Adeptus Arbites is based at the Fortress of the Just, a massive rockcrete slab that sits in the relentless desert a short flight away from Hive Tarsus. It is here that Lord Marshal Goreman's headquarters can be found, along with the training facilities for the arbitrator cadets sent to the Calixis Sector, and the Sector Judicial archive. The Divisio Immoralis is based in a cramped set of offices in the Archive, while Scintilla's large pool of Enforcers trains regularly in the bullet-scarred mock town just outside the fortress.On Sepheris Secundus, the arbitrators are based at the Isolatorium and are mainly concerned with battling cults and mutant groups among the massive serf populations of the planet's mines. On Iocanthos, the Adeptus Arbites' presence is limited to a single squad of Enforcers and arbitrators stationed at Port Suffering, although they are almost always to be found out in the Wasteland following up some new allegation of cultists or rogue psykers.
