First published in 2014, Gav Thorpe’s Blood Angels short story Sanguis Irae acts as a companion piece to the novella Sin of Damnation, and is available either bundled with the novella or as a standalone e-short. It follows the exploits of Librarian Calistarius as, many years after the Sin of Damnation mission, he boards another space hulk and uses his powers to search for answers within the mind of a dying Blood Angel. What he finds there, amongst the fractured recollections of Sanguinius brought on by the Black Rage, shows him the grave danger he and his brothers are in.
