Sergeant Chronus

Sergeant Chronus is an Ultramarines sergeant of the Adeptus Astartes, recorded as an armoured-vehicle specialist of the Chapter whose seat is Macragge. He holds the rank of sergeant, a veteran non-commissioned command within a Chapter that organises itself according to the Codex Astartes, and is associated in the record with the operation of heavy tracked vehicles rather than with the line squads for which the Chapter is more commonly described.

Accounts of his origin are sparse. Nothing firm is recorded of his recruitment on Macragge or Ultramar, of his early service in a battle-company, or of the training that led to his particular role, and later tradition should not be assumed to supply these details. What is held is that he served as a tank commander in Ultramarines armoured formations, working alongside battle-brothers of the Chapter and answering to the captains and the Chapter Master who direct its wars. Specific campaigns, named engagements and relationships with rivals or pupils are not established here, and this dossier does not extend them beyond what is attested.

Chronus’s significance is that of a representative figure: a sergeant whose place in the Ultramarines’ order of battle illustrates the armoured arm of a Chapter that fields Rhinos, Predators and Land Raiders as readily as it fields infantry. His map anchor is Macragge, the Ultramarines’ homeworld in the Ultramar subsector, and his timeline placement is the 41st millennium, within the Chapter’s long service under Marneus Calgar. His present status is not recorded; whether he is active, fallen or reassigned is unknown, and the page will be revised should firmer particulars be confirmed.
