When you F**k up Star Wars

What happens when a man from earth is reincarnated into the Warhammer 40k universe? He becomes a god of course. Now tell me, what happens when said man is reincarnated into the Star Wars universe? He becomes the devil!! The start will be similar to my other active novel, The Multiversal Empire. Bare with it as it will lead to a better story in the long run.
