A mortal was chosen by the Ultramarines and underwent nineteen genetic modifications to become a Space Marine. Since then, he and his team have faced the Tyranids, the Green Orcs, fought against the evil god Slaanesh, eliminated the rebels, and forged brotherhood and glory in the brutal war.

The ordinary Lynn was thrust into the darkest battlefields of the Warhammer 40,000 universe.

Struggling to survive in the ruins of a hive city, a sea of ​​blood and corpses, he was forced into the Imperium's most brutal meat grinder: witnessing Cadia's shattering chaos, battling the infernal Zerg Sea of ​​Baal, wandering beneath the shadow of the Tau Empire's "Greater Good," and even encountering forbidden relics on the edge of the Eye of Terror.

Fighting bloodily for survival, he transformed from a terrified mortal into a ruthless warrior.

However, endless wars and repeated profound transformations by the Mechanicus eroded his humanity and self, pushing him to the brink of inhumanity.

Scarred and wounded, he traversed the burning galaxy, ultimately arriving at Holy Terra, humanity's last bastion.

Facing the final siege of Chaos and the impending extinction of the Golden Throne, Lynn must make the ultimate choice: using his utterly alienated existence and otherworldly soul to become the nameless fuel that sustains the Emperor and the Imperium.

This is his journey, burning himself out in eternal darkness, to become the last ember of the Imperium.
