The gods left machines behind. The Cult of Kosmos learned how to turn them into monsters. Now Lannor intends to steal that power before it consumes another world.

Stranded in ancient Greece, Lannor has fought beside Kassandra, survived assassins, and watched divine artifacts rewrite flesh. Their next target is a blood-worshipping killer who has transformed himself into something stronger than human—and commands a weapon capable of making beasts out of men.

For Lannor, the hunt is more than survival. The relic may be the key to completing his Astartes transformation, unlocking new abilities, and controlling the rifts between worlds. With his biological intelligence core analyzing every enemy, Witcher Signs in his hands, and Kassandra at his side, he is ready to bring down a false god.

Then he returns home.

Cintra is burning. Nilfgaard has crushed its armies, civilians are disappearing, and two Witchers entered the war zone because of a message Lannor sent. Leaving them behind is not an option.

To reach them, he must complete the third stage of his transformation, cross a conquered kingdom alone, and face an enemy more dangerous than any monster: disciplined soldiers who believe slaughter is civilization.

This dark LitRPG progression fantasy delivers relentless monster hunting, system-guided power growth, brutal boss battles, ancient technology, Witcher combat, and a hero evolving toward something no army was built to stop.

But when a signal sounds from the darkness after the last soldier falls, Lannor realizes the patrol was only the beginning.

How many legions will Nilfgaard send to kill the monster hunting them?
