Founding

A Blood Raven AstartesThe precise Founding in which the Blood Ravens were created is unknown; their own chapter histories only begin in M37, though other Imperial records contain some small references to the Chapter as existent before then. It is important to note that the Blood Ravens' histories are completely absent before the M37 date; they are not just spotty or fragmentary records. As a result, the Astartes of the Chapter know absolutely nothing about their origins, including having no knowledge of their primogenitor legion or primarch. This absence of information about a primarch has resulted in the Blood Ravens focusing their spiritual reverence on the Emperor. However, they do have one particular mytho-historical figure of import in the form of Azariah Vidya, known as the Great Father of the Blood Ravens.2d

Azariah Vidya is reputed to have been a member of the Chapter during its first years. According to the legend (for actual records of this event apparently do not exist), during a disastrous campaign against a Chaotic uprising in the Gothic sector, their Chapter Master, Master of Sanctity and most of their elite 1st Company were killed in action. The young Chapter, now without much of their senior cadre, turned to Chief Librarian Vidya for leadership. Vidya, already said to be an expert in the ways of the Ruinous Powers, turned to both research and guile to achieve victory, using Imperial Guard forces to probe and distract the enemy before leading surgical Astartes strikes on important heretic locations that critically disrupted not only their military lines but also their sources of eldritch power. The campaign was swiftly ended in favour of the Imperium, and in the aftermath it was discovered that the whole rebellion (and therefore the associated extermination of the Blood Ravens veterans) had been organised by the Alpha Legion.2d

Vidya was asked by the 'Secret Masters' of the Chapter to officially become Chapter Master; something he did while retaining his position as Chief Librarian.2d This resulted in the tradition of the Blood Ravens whereby Librarians are afforded dual-roles as command officers.2b
