Changes

Their colour scheme is the reverse of the Ultramarines', replacing the blue with the white and vice-versa, although the shoulder trim still displays the company colour as per [[Codex Astartes]] dictate.{{Fn|2}} As one of the Ultramarine Ultramarines successors located farthest from [[Ultramar]], it is rare and a cause for celebration when the White Consuls appear in the court of [[Marneus Calgar]].{{Fn|6}}

Unusually the White Consuls have two [[Chapter Master]]s, ; one who oversees the defences of the Chapter's [[Adeptus Astartes Homeworld|home world]] of [[Sabatine]] and commands a standing force ready at a moment’s notice to respond to [[Chaos]] incursions through the [[Cadian Gate]], and the other is responsible for the operations of the Chapter's forces in war zones further afield. It is doubtful that this is sanctioned by any entry in the [[Codex Astartes]], and the reason it has never been challenged is the Chapter's homeworld's distance from Ultramar.{{Fn|6}} Also unusually the White Consuls seem to worship the Emperor as a god and seem to be part of the [[Imperial Cult]], unlike most other Astartes Chapters.{{Fn|5c}}

The White Consuls maintain sovereignty over several nearby systems, and the chapter officers are expected to oversee the administration of each world before advancing to a higher rank. As such , these officers are often found in command of local troops. This is considered as a smaller version of the Ultramarines' practice practices within Ultramar.{{Fn|6}} One these was the [[Boros System]], which they ruled from the [[Kronos]] star fort '''Kronos''' (the largest space station in [[Segmentum Obscurus]]) , until the entire system was corrupted and the Kronos star fort destroyed by the dark crusade of the [[Word Bearers]] and the subsequent invasion of the [[Necrons]], under the [[Undying One]]. [[Proconsul]] [[Cassius Ostorius]] & [[Coadjutor]] [[Gaius Aquilius]] seemed to be the only two Astartes involved with the governorship , however.{{Fn|5a}}

Every battle brother has to serve as a Coadjutor in the years after rising from the rank of neophyte. A selection of veterans are also chosen to act as Proconsuls; becoming a Proconsul is a necessary prerequisite to becoming a [[Space Marine Sergeant|sergeant]] or [[Space Marine Captain|captain]].{{Fn|5a}} Proconsuls have led local troops of Sabatine or their vassal worlds into battle, granting them some knowledge on the [[Imperial Guard]].{{Fn|6}}

When the [[Thirteenth Black Crusade]] started, the White Counsuls answered to call of [[Cadia]] by sending all of their Companies , except the Fourth, who were left as a skeletal guard of the planet [[Celestine (Planet)|Celestine]] planet.{{Fn|14a}}

In the aftermath of the [[Great Rift|Great Rift's]]'s creation, during the [[Thirteenth Black Crusade]], the Chapter's Homeworld was overrun by the forces of [[Chaos]]; though the remnants of the Chapter managed to escape{{Fn|10}} before Sabatine was remade to corrupted by the forces of [[Nurgle]] planet.{{Fn|14c}}

*'''???.[[M42]]''' - The invasion of [[Sabatine]]. The [[Lords of Silence]] and the [[Weeping Veil]] warbands invades invaded the White Consuls homeworld. With the majority of the Chapter engaged in the 13th Black crusade, only 80 Battle-Brothers are present on Sabatine. [[Chaos]] forces from the [[Lords of Silence]] and [[Weeping Veil]] are able to destroy the White Consuls garrison on the planet{{Fn|14a}} before the remastering corrupting it to in the name of [[Nurgle]] purposes.{{Fn|14c}}

The White Consuls are known to possess three [[battle barge]]s, ''[[Sword of Truth (Battle Barge)|Sword of Truth]]'', ''[[Divine Splendour]]'' and the ''[[Righteous Fury (BattlebargeBattle Barge)|Righteous Fury]]''.{{Fn|5b}} They are also known to possess two [[strike cruiser]]s, the ''[[Hermes]]'' and the ''[[Eternal Faith]]''.{{Fn|3}}{{Fn|12}}
