Codex: Chaos Space Marines (2017), p53 — Deathmongers

Brother Bellicor, knife fighter of the Deathmongers slaughter cult

Upon the crone world of Belial IV, the Brothers of the Anvil scoured the spires of the original Eldar empire, only to be brought to battle by Drukhari Kabalites searching the ancient planet for ancient treasures. After a year of nightmarish ordeals in the Commorrite arenas, the broken remains of the Brothers of the Anvil slaughtered their way back into realspace, where they killed every living thing they found. They are now known as the Deathmongers.
