Warhammer 40k World Eaters Codex

The World Eaters are ferocious transhuman warriors driven by a burning need to unleash violent savagery. Once a Legion loyal to the Emperor, they long ago followed their Daemon Primarch, Angron, into worship of the Chaos God Khorne. Clad in power armour corrupted with the iconography of their dark god and clasping chainblades, they hurl themselves at the enemy, hacking and dismembering in a killing frenzy.
