Within the Legio Custodes, there exists a range of ranks and seniority of commands, far from transparent to outsiders, to which the more general application of ‘Shield Captain’ is applied, though within the Legio such ranks range from Prefect to Lictor, Proconsul to Tribune, following the ancient patterns of Terra’s lost history. Elevated both through the trust held among their peers for their judgement and skill, but first and foremost advanced by the direct approval and in some cases intervention of the Emperor Himself, these are warriors not only of consummate and superhuman ability, but also rare insight, acumen and knowledge. Afforded the rarest and finest of the Imperium’s arms, each of these legendary fighters commanded the Legio Custodes against all manner of threats against the Emperor, His works and His domains.
