[[Gregor Eisenhorn]] refers to the "Primarchprimarch" of the [[White Consuls]] [[Space Marine Chapter]], when stating that he made it a point to commend a heroic [[Space Marine Sergeant|Sergeantsergeant]] who saved his life, at the cost of the Sergeantsergeant's own, on [[Thracian Primaris]]. Since the White Consuls are a [[Successor Chaptersuccessor chapter]], and because there were no living or active primarchs within the Imperium at the time of these events, he seems seemed to be using the term "Primarchprimarch" interchangeably with that of [[Chapter Masterchapter master]].{{Fn|5}}
