My Sandbox Is the Warhammer Universe

Lin Fan, a down-on-his-luck college student, picked up an antique-looking, mysterious wooden box at a secondhand market. He thought it might contain priceless antiques, but when he opened it, he found an exquisitely detailed, lifelike model of an interstellar battlefield. As he tried to repair a damaged Space Marine miniature, the world inside the diorama changed dramatically, and a "miracle" descended from the heavens to save the warrior's life. To his horror, Lin Fan discovered that the diorama was a real miniature Warhammer universe! And he was the one true god of that world!

He could spend "Fate Points" to influence anything in that world. He could issue divine revelations, bestow blessings, and even change the fate of heroes! At that moment, the diorama's timeline was set during the darkest hour of the Imperium of Man, on the eve of the Horus Heresy. The ambitious Warmaster was about to rebel, loyal Primarchs would be slaughtered, and the glorious Imperium would be plunged into a fire from which there was no escape.

Lin Fan decided he couldn't stand by and let the tragedy happen! He would save this dark universe! He would stop Horus and save the heroes who were fated to fall! But just as he tried to intervene in a Primarch's fate for the first time, sending a warning to Magnus the "Red Angel," an immense, boundless will from the heart of the diorama universe pierced the barrier between reality and illusion in an instant.

Inside the diorama, the Emperor, seated upon the Golden Throne, slowly raised his head. His gaze crossed dimensions and met Lin Fan's in the real world!
