Rubicon's Dawn: The Fall of the Imperium and the Rise of Chaos

In the dying embers of a shattered Imperium, a group of loyal soldiers is caught in a relentless battle against the forces of Chaos-and against themselves. When Captain Dorian, once a proud servant of the Emperor, succumbs to the twisted power of Slaanesh, he is transformed into a monstrous hybrid Dreadnought, forever changed by the dark forces he once swore to destroy. As the world crumbles beneath the awakening of a long-buried Chaos Titan, Dorian must confront the horrors of his own existence while facing the treacherous Alaric, a former comrade now fully consumed by daemon power.

With the planet itself revealed as a weapon of chaos, and betrayal lurking at every turn, the surviving soldiers must decide whether to fight on for an Imperium already beyond salvation-or escape into the unknown to avoid certain death. As a forbidden ritual draws in more daemons, and the final battle looms, the true price of loyalty is revealed. The line between hero and villain, man and monster, has blurred forever.

In Rubicon's Dawn, the fate of humanity is sealed as the Imperium falls, and Chaos rises-ushering in a new era of destruction, sacrifice, and unrelenting darkness.
