(some few inspirations from sagas1023) In the chaotic and vibrant neon lit roads of New Eridu, the last remaining city on earth, home to millions of people as the last remnants of humanity huddle into one last bastion that stands against the hollows. In a turn of events a mysterious meteor crashes into the outer ring, but to those of excellent vision, the 'meteor' was too strange to be a meteor, it felt too smooth, it's movements too deliberate. As the city meets giants clad in yellow and gold bearing an aquila never before seen, hailing from a home far into the stars. Things begin to change. 6/1/26 no1 - #Imperium of Man 6/20/25 no1 - #tech

The Emperor of Mankind: "I am not a god." Lorgar: "Of course, my lord. You are merely... divine." Erebus: smiling far too much When the Imperial Truth was proclaimed and enforced, the most widespread symbol of devotion became the Golden Throne icon, officially declared "purely inspirational" and absolutely not religious. Perturabo wages war not for love or glory, but to prove-once and for all-that his genius was never appreciated. Konrad Curze, fully aware of his sanity and damnation, chooses terror and death because the future has already judged him guilty. Magnus the Red sacrifices his eye for knowledge-and later sacrifices everything else trying to undo that choice. Roboute Guilliman watches the Imperium twist his rational ideals into dogma, his legacy buried beneath prayers, relics, and bureaucratic rot. Angron does not "wear" the Butcher's Nails. The Nails wear him. The Emperor looks upon the Primarchs and says, "I created you to save humanity." Then, without hesitation, he unleashes his psychic might-casting Erebus and Lorgar down in chains, spinning helplessly in the consequences of their own faith. This chronicle is also known as: "The Imperial Truth (Briefly)" "How Not to Raise Demigods" "Erebus Ruins Everything" "The Word Bearers are converting worlds again!" "The Emperor is silent!" "Erebus must die!" Author: Baltan The Lobster

​He was the only son of the Emperor who dared to call the Imperium a failure. ​Primarch Valerius was lost to the annals of history, a forgotten relic of the Great Crusade. Unlike his zealous brothers, Valerius was not ruled by faith or fury, but by one absolute law: The Doctrine of Necessary Utility. ​When the Sovereign Arbiter of Humanity's Survival returns, he finds the Imperium crippled by superstition, bureaucracy, and a war fought with obsolete doctrine. The revered Codex Astartes is merely a roadmap to failure, and the High Lords are worse than any Xenos threat. ​Valerius refuses to lead a rebellion. Instead, he begins a surgical, systematic crusade to prove that the only path to survival is absolute, ruthless efficiency. He builds the Aegis Imperium, unites the fragmented Space Marine Chapters under his cold, logical command, and forces Roboute Guilliman to yield to a new form of governance. ​His purpose is singular, and his final vow is the most dangerous of all: to gather forbidden relics, breach Holy Terra, and attempt the impossible-to restore his broken father on the Golden Throne. ​A Primarch's logic will either save humanity or shatter it forever. Experience the saga of the Primarch who broke every rule of the 41st Millennium to fulfill the Final Vow.

The emperor of mankind has died. The forces of Chaos stirs the imperium in a fight more desperate than even. Until the whispers of a child radiant with golden light begins to spread.

"We are but the Emperor's tools, forged in the fires of His wrath, wielded in the defense of His realm. We do not fear death, for in sacrifice, we find purpose. We do not seek glory, for only the Emperor's light endures. We do not falter, for duty is our only salvation. For Krieg, there is no peace. For Krieg, there is only war." (Slowburn Harem)
