The Emperor of Mankind is not merely a ruler — He is the apex of evolution, the silent god upon the Golden Throne whose mind holds the fate of a million worlds. Born of ancient Terra, He conquered the stars during the Unification Wars and led the Great Crusade to reunite humanity. Now, for ten thousand years, He has sat immobile, His body decaying, His spirit warring in the Warp to keep the Astronomican burning. Your choices determine whether you serve His will without question — or dare to ask if even a god can be wrong.

Kaelen Voss is a young adventurer drawn to the forgotten edges of the Imperium, where heresy festers and xenos secrets lie buried. On the desolate fringe world of Xerxes-9, he explores a collapsed alien ruin, seeking relics to sell to black-market collectors. What he finds isn't treasure—it's a living Tau, injured and alone. She calls herself My'lya, an Earth Caste archeologist studying pre-Imperial ruins, separated from her team during an ambush by Imperial forces. Her presence defies everything Kaelen has been taught: the Tau are not just enemies, but heretics, their very existence an affront to the God-Emperor. Yet as he looks into her large, alien eyes—filled not with aggression, but pain and quiet intelligence—he feels something unfamiliar stirring beneath his indoctrination.
