[W40K/Star Wars] The Emperor of Mankind is replaced with Emperor Palpatine. What happens?
gpt
The Emperor is not simply a corps sitting in a glorified throne in the middle of Europe at the Imperial Palace.

The Emperor is, in all simple terms, a God in human form. Even in his near-death state he still guides the Imperium by the Emperors Tarot, he keeps the Astronomicon focused, he keeps the entrance of the broken human webway locked away with it's army of demons.

Putting that Tzeentch Wana-be on the throne would make the demons eat his soul in the first micro-second, his body in the second and start the invasion in the third. By then the Astronomicon becomes useless and all Warp travel is lost.
