YMMV: Word Bearers

  • Fridge Logic: In the third book, the Undying One starts using the Nexus Arrangement to cut off the Warp influence around the planet. Teleportation throws people through the Warp. Oops.
  • Magnificent Bastard: Erebus single-handedly caused a war between two civilizations, leading to the complete annihilation of one, stole the most powerful artifact of one of those races, orchestrated the downfall of Humanity's greatest protector, caused a galaxy spanning civil war that almost destroyed the Imperium and is indirectly responsible for half the Space Marine legions converting to the worship of Chaos.
  • Nightmare Fuel: All the descriptions of Varnus' predicaments are this.
