Warhammer: Reborn as Zhulong, Why Is the Imperium Panicking?

[Warhammer 40K + reborn as a monster + invincible protagonist + Lovecraftian speculation + shadowy mastermind + no saintly do-gooder]

When Ignis woke up, he discovered he had been reborn in the grim, dark universe of Warhammer 40K as an ancient, unknown genetic behemoth lurking in the depths of a border Death World!

His physical body was virtually indestructible, and the mist in his mouth could even warp the constants of reality. All he wanted was to quietly digest energy and complete his “genetic leap,” sleeping in the abyss until the end of time.

He didn’t know that the occasional roll of his body, which triggered landslides and tsunamis, had led the surviving Imperial rabble to worship him as the “Merciful Dragon King of the Abyss.”

He didn’t know that the scales he shed had been treated by the Adeptus Mechanicus as “sacred fragments of the Omnissiah,” sparking a great schism of faith within Mars.

He didn’t know that a single breath from him had dispelled the whispers of Chaos, causing a passing Inquisitor’s faith to collapse on the spot. Trembling, the Inquisitor wrote in their report: “Possibly an ancient divine creation of the Emperor!”

As he grew from a hundred meters long to ten million kilometers, devoured C'tan Shards, fought Primarchs head-on, and used psychic mist to shield an entire sector...

Guilliman wearily closed the report. “A ‘wild xenos’ capable of healing the Great Rift single-handedly and making the Dark Gods afraid to look at him? I suggest we leave him undisturbed while he sleeps.”

Ignis yawned as he looked at the ever-growing number of fanatical followers in his psychic domain, his face full of innocence. “I never wanted to be a savior. These neighbors are just too noisy. They forced me to get up and keep them in line.”
