   Summary

   With each year the Indomitus Crusade progresses, the Chaos Gods grow more and more annoyed as Roboute Guilliman continuously interferes with their plans and powers. But they know killing him will be too difficult and costly; the Corpse Emperor of Mankind protects his tool well. So, instead, they lay a trap and cast the nuisance 13th Primarch into an alternate timeline.

   AKA, that time when 30k and 40k Roboute Guilliman swap places.
