• The Orks advanced toward Torati World, where a battle moon linked to both forces was discovered, threatening to bring their armies together.

• On a front-line fortress world, humans fought an overwhelming green tide as the Orks' numbers and battle moons converged.

Two Ork tyrants’ forces converged on the human fortress world, tearing apart Imperial ships and battling across Attila as Chaos forces withdrew. More Orks and battle moons continued arriving, while a Chaos fleet detected an enormous, unidentified armada.
