As the whole organization consists of inviduals rather than suborganizations, this is not a really good place to expand upon. They are the Emperor's will and rule in his name. Īs said, everything (beside the Inquisition) in the Imperium is under jurisdiction of the High Lords of Terra. The rest three seats may be held filled from a range of the highest officials in the Imperium.
Nine of the twelve seats are virtaully sacrosanct and are always held by the Fabricator General of Mars, Master of Administratum and Paternoval Envoy of the Navis Nobilite. High Lords of Terra are twelve inviduals who rule in the Emperor's stead. Where Inquisition is extremely fan-friendly for expanding (see below), High Lords of Terra don't really have much room for extra additions. Both of them answerable only to the Emperor himself, below the High Lords resides everything else in the Imperium of Man for they rule in Emperor's stead. The two most powerful, or influential, organizations are the High Lords of Terra and the Inquisition. Some of the canon organizations are however so powerful and affect everything within the Imperium that to write a fanon organization which would rival them is simply put a bad idea. Throughout the editions of Warhammer 40,000 it is emphasized that the Imperium is a myriad, bureucratic labyrinth and as a fanon author you don't really need to worry if there already exists an organization that shares traits with the one you are about to write! Only the most prominent, powerful and widespanning organizations of the Imperium are described in the 40k universe and so creating new ones is more than welcome. This is of course a good opportunity for any fanon author out there to expand on the Imperial authorities. This is no wonder as many of the organizations within the Imperium are so complex and byzantine that no existing catalogue of their areas of influence, or even their function, exists. Imperium of Man is littered with organizations, Adeptuses, offices and departments, each overlapping others creating multiple layers of authority and officiality.
