Imagine being the empire's most lethal shadow, an assassin whose name strikes fear into the hearts of all, yet living your entire life as a forgotten tool. That was the tragic reality of Cyan Vert. The illegitimate son of a powerful Duke, Cyan was thrust into the darkness, his unparalleled skills honed into a deadly art, all while he existed solely to serve in the shadow of his 'righteous' brother. But fate, or perhaps a crueler irony, had a final, devastating betrayal in store. Just as his life was about to be mercilessly extinguished by the very hand he trusted, a miracle—or a second chance from hell itself—occurred.

Cyan awakens, not in the cold embrace of death, but back in his own past, a mere boy once more! This isn't just a reprieve; it’s a fiery rebirth. No longer content to be a pawn in someone else's game, no longer willing to hide in anyone's shadow, Cyan Vert is back with a vengeance. Armed with the memories of a master assassin and a burning, unshakeable resolve for retribution, he'll carve his own path through the treacherous political landscape of the dukedom and beyond. Get ready for an electrifying journey where a regressed assassin rewrites his destiny, crushes his enemies, and forges his own legendary name. Can a child of darkness truly claim the light, or will his past catch up to him in this exhilarating fantasy of action, cunning, and revenge?
