Warhammer: Star Lords in the Age of the Great Crusade

M30, the most glorious era of the human empire. The Emperor leads an expeditionary fleet to conquer the galaxy, eighteen Primarchs return to their posts, and millions of Space Marines embark on the journey. This is the closest humankind has come to the Golden Age. It is also the last dawn before darkness falls. Lu Yu, an ordinary officer from a marginalized colonial world, accidentally obtained the [Civilization Fire Core] left over from the golden age during an expedition. He has no Primarch blood, no powerful genes, and no qualifications to become a Space Marine. But he possesses an ability that is enough to change the galaxy - to see the future direction of civilization. When the Empire relied on war to unite the galaxy, he chose to build. When the nobles pursued glory and resources, they chose to let countless ordinary people survive. Starting from a border planet on the verge of destruction, he restored lost technology, established an industrial system, cultivated new humans, and created a path of human evolution that did not rely on the original body. He went on expeditions with Horus and discussed the future of the Empire with Guilliman. He had seen the perseverance of Dorne, the wisdom of Magnus, and the cracks hidden behind the Golden Crusade. Until that day, Horus raised his banner of rebellion and the galaxy fell into war. Everyone believes that mankind is destined to go into darkness. Only Lu Yu knows. The real enemy has never been the rebellious Primarch, nor the evil god of the subspace. But the future that cannot be changed. "The Emperor created the Empire." "And I want to create a human civilization that can continue even if the Emperor is lost."
