In a world where magic and steampunk technology intertwine, Lucius Van D''''Arques is reborn with the memories of a life marked by blood and crime. He was once Yoo Chan-Yeol, a murderer whose shadow still haunts him. Now, with a noble lineage and a destiny that draws him toward greatness or perdition, he must navigate between the splendor of the aristocracy and the secrets buried in the bowels of the kingdom. But his past is not the only thing that threatens to consume him; hidden forces conspire in the shadows, and the echo of a forgotten name begins to resonate in the streets: Jack the Ripper has returned.
