Marcus (Crusader Host)
Marcus was a member of the Blood Angels Legion.[1c]
He served in the Crusader Host on Terra during the last years of the Great Crusade.[1c] However, after the Horus Heresy began, the Primarch Rogal Dorn was unsure of the Host's loyalty to the Imperium. Because of this, Dorn had[1a] Marcus[1c] and the other members of the Host incarcerated within Khangba Marwu prison.[1b]
