I really admire the first person who made a deal with the Four Gods. Maybe he would become paralyzed on the toilet.
Yellow skin, when I make a subspace water pump, I will definitely make you awaken
People will eventually step down from the Golden Throne
Let me say it again, technology is about to accelerate!
Solar Tomahawk
Thor Mecha
Arc Generator
Hyperspace Channel
Warp Drive
"Cybercles"
Ether Phase Engine
"Oum Messiah Reborn"

Serious version:
Leon, who has traveled to the remote Warhammer of the M32 era, has become a soulless man. With the knowledge he gained from many other science fiction works before traveling through time, he transformed himself into a priest of the Mechanicum.

Punch the greenskins, kick the chaos, gather the traitor legions, and reshape the future of mankind...

"Open the door! I'm really here to save the emperor from the toilet!"
