The Blood Ravens are a Loyalist Space Marine Chapter of unknown origins and Founding. The origins of the Blood Ravens are shrouded in mystery and are belived to be tied to a dark truth related to the Horus Heresy. This elusive Chapter has always been drawn to the pursuit of knowledge and the acquisition of ancient lore and produces an unusually high number of Librarians among its ranks as a high proportion of Neophytes develop psychic abilities soon after their implantation with the Blood Ravens' gene-seed organs. The powerful Blood Ravens Librarians guide the Chapter, enabling them to fight with a precision and calculated fury made possible by their ability to predict and thwart their enemy's strategies and tactics before they come to pass. These arcane powers have led to great speculation and some worry about the true nature and origins of this Chapter in the rest of the Imperium of Man.

As much as they are known for their bravery and combat efficiency, the Blood Ravens Chapter is also renowned for its obsession with recovering lost information and technology. These Battle-Brothers have repeatedly shown a willingness to accept non-traditional techniques and extreme approaches so that some lost relic or tome could be recovered and secured within their vaults. Their tendency to rely heavily upon a higher than normal number of psychically-talented Space Marines only serves to further differentiate the Blood Ravens from most other Chapters. Some members of the Adeptus Administratum believe that this reliance upon their psykers is a potential disaster, while others respect and fear the advantages these talented Battle-Brothers have repeatedly provided to their Chapter. http://warhammer40k.wikia.com/wiki/Blood_Ravens
