Warhammer: The Emperor's Raven Messenger

The 30th Millennium of the Imperial Calendar, the Unification Wars are drawing to a close, and the Primarchs have been scattered across the galaxy.

The Emperor is preparing to launch the Great Crusade, reconquer the galaxy, and restore humanity's former glory.

A transmigator has become a Raven, possessing the ability to traverse all worlds by binding himself to destined protagonists.

That day, the Raven shouted at the golden giant, "Let's go, let me show you the world."

Thus, the Emperor brought back advanced technologies such as the Gene Engine from the DC Universe, Protoss technology from StarCraft, the Death Star technology from Star Wars, the Aetheric Phase Engine from Stellaris, the Allspark from Transformers, and dimensional weapons from the Three-Body Universe into his own.

Years later, the armies of the Human Empire, holding the double-headed eagle banner, conquered universe after universe.

Facing accusations from numerous displaced Chaos Gods, the Raven scratched his head sheepishly.

"I just wanted to show that golden giant the world at first. Who knew he'd immediately proclaim 'Unify the Heavens, for it is our race's manifest destiny.'"

"So, you really can't blame me for this."
