He was Sa-cheon - the Sword God. The Overlord. The one and only man in history to unify both the Central Plains and the lands beyond, the absolute being before whom sect leaders and palace lords bowed their heads in fear.

Then his seven disciples betrayed him, cutting him down with the very martial arts he had taught them. Left trapped at death's door, his body broken but his mind intact, he counted the endless years in suffocating darkness - until even the faces of those he swore to kill faded, leaving only fear, loneliness, and a blade of vengeance ground sharp against the void.

When he finally claws back into the world, it is to a murim that has forgotten him. A martial world ruled by cruelty, where the tyrant Dam Kang-hyeon murders his own father to seize the Cheonjin Sect and hunts down his sister, Dam Ye-rin, the one person who pulls Sa-cheon from his grave.

Now reborn into a new age and a new power, the fallen god takes up the sword once more. The disciples who betrayed him still walk the earth. The sects that bowed to him have forgotten his name. He will remind them all - one severed neck at a time.
