Corvus Corax is the primarch of the Raven Guard, one of the original Space Marine Legions in the Warhammer 40,000 universe. Known for his expertise in stealth and guerrilla warfare, Corax led his Legion with a focus on speed, precision, and surprise attacks. His origins on the mining world of Lycaeus, where he led a rebellion to free his people from oppression, shaped his deep sense of justice.
Under his leadership, the Raven Guard became specialists in covert operations, striking from the shadows and avoiding unnecessary bloodshed. Corax’s approach to warfare was rooted in the belief that wars should be fought with precision and minimal collateral damage, making his Legion one of the most distinct in the Imperium.
During the Horus Heresy, Corax remained loyal to the Emperor but suffered a devastating defeat at the Dropsite Massacre on Istvaan V, where his Legion was nearly wiped out. In a desperate attempt to rebuild, Corax used accelerated gene-seed growth techniques, leading to tragic mutations among his troops, a burden that weighed heavily on him.
After the Heresy, Corax continued to battle the forces of Chaos but grew increasingly isolated and disillusioned. He eventually disappeared into the Eye of Terror, vowing to hunt down the traitor primarchs, and his fate remains a mystery, with only fragments of lore suggesting his continued existence.
