It was Vashtorr the Arkifane who was trying to become a Chaos God in Warhammer 40k. He’s an unaligned daemon power tied to invention, machines, and dark innovation, and in recent lore he’s been pursuing ascension as a fifth Chaos God.

Quick Scoop

  • Vashtorr is not one of the four main Chaos Gods.
  • He rules the Forge of Souls and leads the Cult of the Arkifane.
  • In the Arks of Omen storyline, he allied with Abaddon and pushed a plan tied to mysterious key fragments.
  • His goal was to grow beyond daemonhood and claim a seat among the Chaos Gods.

Why people mention him

Be’lakor also gets dragged into this kind of discussion because he sits outside the usual four-god setup and is often treated as a rival power in the Warp. But the specific character who openly seeks that “fifth god” status is Vashtorr.

TL;DR: the one trying to become a Chaos God was Vashtorr the Arkifane.
