Warhammer: Primarch and King of Space

In the 30k era, the Emperor leads humanity in the Great Crusade. It seems everyone believes humanity's fate will return to the Golden Age when the Emperor's grand vision comes true. With the Primarchs returning, the Imperium gradually reaches its peak, until...

"Then let the galaxy burn!" Watching the video of the traitorous Warmaster, Lu Yi looks again at the Space King, who has already conquered the galaxy by the time the video starts. "I feel like the Emperor can't compare to the Space King."

Warning: Psychic mega-slaps incoming! And so, Warhammer gets another "willing" lucky soul to transmigrate.

"Yeah! I'm going to build the Second Imperium, you hear!"
