"In the dark and distant future, there is only war. When the ancient Doom Slayer awakens once more by the Emperor’s will, and when the gaze of the primordial Four turns again upon the material universe, the veil between realms grows ever thinner. In this age of crumbling barriers, can the Doom Guy truly bring hope to humanity—or even the entire galaxy—as the Emperor desires?"

(Note: This is an ensemble narrative—readers who dislike this style, beware! While Doom’s storyline is absolutely present, the early chapters focus more on a sprawling cast, akin to the "Roboutian Heresy" fanworks. This is a fresh timeline, so the return of the Primarchs and major battles may not follow chronological order. That said, core lore remains intact.)

In the madness of the fortieth millennium, only war exists in the universe.

But in the deepest part of the subspace, a consciousness originating from humanity's ancient golden age has awakened. It calls itself "Somos," the end of suffering, the eternal stillness.

Now, He whispers into the ears of the most desperate souls, offering a false peace. Neither the empire nor the gods realize that this faint whisper is quietly weaving an ending that will overturn everything.

Expedition! Expedition!! The Great Crusade!!!

The days of humanity barely surviving under the oppression of xenos and Chaos are over. Furious, humanity is determined to recreate the glory of the Golden Age.

The grievously wounded and dying Emperor of Mankind has healed his injuries and risen to face the enemy. The Lord of the Crimson Torrent roars as he returns from the Warp.

Forward! Nothing can stop the march of our great renaissance!

Forward! The unyielding human civilization, fighting against heaven and earth, swears to restore its former glory!

Forward! Unite, and unite again! We will liberate the entire galaxy!

Nine hundred years into the forty-first millennium of humanity, a crisis brewed that would shape the fate of the entire galaxy. Beyond the farthest point ever reached by the Sun Lord's expedition, within a halo of stars that the expeditionary force had never set foot on, lay a human civilization distinct from the Empire. They considered themselves descendants of the Golden Men and dubbed themselves the Human Federation. Qiao Wen, fortunately, found himself within the Human Federation. As the sole person handling external affairs for this civilization, he discovered that he could rely not only on ancient human technology but also on his own innate magical powers.

In the distant, mist-shrouded star system lies the planet Mordovia—a forgotten fragment tucked away in the Empire's fringes, perpetually veiled beneath oppressive leaden clouds. Across its surface, towering hive cities rise like monstrous steel behemoths, spewing acrid smog into the skies. Between these urban sprawls stretch vast wastelands of festering ruins and toxic marshes, their putrid stench a testament to the planet's decay.

The story takes place in a different world where magic resources are strictly controlled by the mage class, and spellcasting is the exclusive privilege of the upper class. As a special group of beings, gene sorcerers possess psychic talents that allow them to cast spells without the need for magic circuits, but they are long suppressed by the mage forces.
