The Doom Slayer answers the call of a dying world. The Old World faces extinction as Chaos reigns supreme. With his sword of vengeance in hand, the Slayer enters the world to change the tides of war. No longer will there be the laughter of thirsting gods. Only their screams.
Even when lost to ages time, even when a universe is rebirthed, even when the first Chaos God is killed, he lives on. Rip and Tear until it is done.
An'ggrath continues a bloody crusade through Imperial space and no one can stop his wrath. The last planet of the sector is about to fall but from the ashes and flame he shall rise again to Rip and Tear until it is done, it is never done. The war is just beggining as the Doomslayer resumes his eternal battle once again
What if the Doom Slayer was one of the Warp Gods the Emperor chose while creating the Primarchs and if Argent D'Nur was a lost human colony half way inside the Eye of Terror? What would change? How different would the Imperium end up by the fortieth millennium?
