Sanguis Irae

Blood Angels Librarian Calistarius, no stranger to battling the dreaded alien genestealers aboard sinister space hulks, faces his greatest challenge yet. Boarding an unnamed vessel alongside his Terminator battle-brothers, Calistarius is assaulted by a creature of prodigious psychic might that brings forth his inner daemons. As he fights off the psychic attack, the Librarian and his fellows must find the creature and destroy it before all fall to the Black Rage.
