The Black Legion is one of the most feared Chaos Space Marine forces in Warhammer 40,000, led by Abaddon the Despoiler, the Warmaster of Chaos. Originally known as the Luna Wolves, they were Horus Lupercal’s legion before becoming the Sons of Horus and later the Black Legion after Horus’ defeat in the Horus Heresy. Abaddon rejected their past failures, casting off their old identity and pledging allegiance to Chaos Undivided, drawing power from all four Chaos Gods instead of one.
Under Abaddon’s leadership, the Black Legion has launched a series of devastating Black Crusades against the Imperium, with the ultimate goal of fulfilling Horus’ dream of overthrowing the Emperor. Their most recent and catastrophic achievement was the splitting of reality itself with the creation of the Great Rift, plunging half the galaxy into chaos. Abaddon wields powerful relics like Drach’nyen and the Talon of Horus, and his brutal tactics and daemonic alliances make him a force of pure destruction.
Unlike other Chaos legions that align with specific gods, the Black Legion thrives on its adaptability, absorbing renegades and traitors from across the galaxy. Their distinctive black and gold armor and the Eye of Horus symbol reflect their dark heritage, but they remain unified in their devotion to Chaos as a whole. Their combination of shock assaults, psychic warfare, and daemonic power makes them one of the deadliest threats to the Imperium, symbolizing Chaos’ eternal war against the Emperor’s domain.
