The Oblivion Butchers are a warband of Chaos Space Marines that splintered from the World Eaters Traitor Legion that can trace their origins all the way back to the disaster on Skalathrax. Most recently, during the 13th Black Crusade, this warband fought alongside the monstrous Butcherhorde, a conglomeration of multiple World Eaters warbands led by the infamous Khârn the Betrayer, who led them in the slaughter of the Imperial world of Amethal in the Diamor System against the valiant defence of the Blood Angels Space Marine Chapter.
- Diamor Campaign (999.M41) - The Diamor Campaign took place during Abaddon the Despoiler's 13th Black Crusade within the Diamor System. Initially led by the Chaos Lord Kranon the Relentless, his Renegade Chapter, known as the Crimson Slaughter, spearheaded the attack on the Imperial world of Amethal on behalf of Abaddon in order to obtain something the Despoiler desired. Due to the madness and unpredictability of Kranon, the execution of the invasion instead fell upon the Black Legion's Chaos Lord Xorphas. The Oblivion Butchers warband would later join the monstrous Butcherhorde alliance, comprised of a coalition of multiple World Eaters warbands and led by the infamous Khârn the Betrayer. This Khornate host descended upon Amethal with but a single goal -- to take the heads of the most worthy and mightiest of the heroes of the defending Blood Angels. The resultant slaughter weakened the barrier between the Immaterium and the material realm to such an extent that the Blood Angels were forced to call for aid from the daemon-hunting Grey Knights Chapter.
The Oblivion Butchers warband wears oxblood (dark red) colours on their battle-plate trimmed in silver and brass, which denotes their allegiance to the Blood God Khorne. The insets of their shoulder pauldrons are brass trimmed in blood red.
The Oblivion Butchers warband's emblem is a blood red rune of Khorne upon a brass backdrop, and is feared across the eighty-eight worlds of the region known as the Riven Spiral.
