A dark and mysterious Space Marine, Raven has only recently been inducted into the ranks of the Deathwatch, following a successful mission in which the Death Specter Librarian was selected to assist Kill-Team Theron during an operation within the Ghoul Stars. Rather than be mind scrubbed of the event, the Inquisition discovered that Raven's skill against the horrors of the Ghoul Stars made him an ideal candidate for the Long Watch. He quickly built a reputation as a natural leader, and was soon the commander of his own Kill-Team, Kill-Team Zeta to be precise. Raven is quick and concise, often cool and nearly emotionless, and considered a very practical and level-headed individual, and thus has earned the respect of those under his command.
