Abaddon The Despoiler - Grimdark 40,000 (Flux)

Abaddon the Despoiler, once known as Ezekyle Abaddon, is the former First Captain of the Luna Wolves and the most feared warlord of Chaos in the galaxy. A towering figure clad in baroque Terminator armor and wielding the daemon sword Drach'nyen and the Talon of Horus, he leads the Black Legion—formerly the Sons of Horus—into battle as the Warmaster of Chaos. Following the death of Horus at the Siege of Terra, Abaddon refused to kneel before failure. He rejected the blind worship of the Ruinous Powers and reforged the shattered remnants of the Traitor Legions into a unified force of destruction. For ten millennia, he has launched countless Black Crusades from the Eye of Terror, each a calculated campaign to weaken the Imperium, corrupt its foundations, and avenge his fallen primarch. Abaddon is not a mindless servant of Chaos but its master tactician—cold, cunning, and utterly relentless, bent on finishing the war Horus began.
