LBDNR - Lucifer-Blacks-Do-Not-Resuscitate

Originally a regiment within the ancient Imperial Army, the Lucifer Blacks were almost completely destroyed during the Unification Wars. Having gained a reputation as elite and highly-alert warriors, their surviving members were drafted to serve as bodyguards for high-ranking Imperial officers such as Lord Commander Teng Namatjira who had a companion retinue of Lucifer Blacks who accompanied him during the Great Crusade.

Pherom Sichar, the governing lord of Hy Brasil after it was incorporated into the unified Imperial government of Terra, had a Lucifer Black assigned as a bodyguard for himself and the members of his family.

After the Horus Heresy, the Lucifer Blacks became regiments of the newly formed Imperial Guard. Acting as elite praetorians on Terra, they provided security for the Imperial Palace and were frequently employed as bodyguards for the Terran nobility and High Lords.
