Among the fractured warbands of the World Eaters, rank is a thing seized rather than granted, and the Chaos Lord is the killer who has seized the most. He rules by the oldest law of the Legion, that the strongest and most murderous shall command, and he keeps his blood-soaked throne only so long as no rival can take his head. Ten thousand years of butchery lie behind such a warrior, his flesh scarred and augmented, his mind flayed by the Butcher's Nails until little remains but the hunger for battle.
In war the Chaos Lord fights at the forefront of the assault, where the blood runs thickest and the favour of Khorne burns brightest. He wields relics of a darker age, daemon-forged blades and crackling power weapons that shear through armour and bone, and his very presence drives the warriors around him into ever greater excesses of slaughter. Every kill he claims is an offering, and the greatest among these lords accumulate such favour that Khorne may raise them to daemonhood; the unworthy, by contrast, collapse into gibbering Chaos Spawn, their ambition curdled into ruin. Between those two fates the Chaos Lord walks a knife's edge, and only the endless offering of skulls keeps him upon it.
