It's an OP!reader isekai. I couldn't find anything online that I had envisioned in my mind, so I ultimately decided to make something to fill that void, Primarchs and all. :) Please comment on any improper or weak wording if you can, it helps me out in the long run especially when I plan to edit those parts (Parts 1-9 have been edited). -Intended for a slow burn, but I will do my best to upload regularly, so no one is left hanging for too long. -Artwork and story are by me, but the Warhammer 40k and Horus Heresy universe, its story, and its characters belong to Game Workshop's. -Do not attempt to repost this story anywhere without my permission on ANY platform, but do inform me if you see anything, please.

​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.
