Franz Bonaparta designed the eugenics program that produced the Liebert twins and wrote the twisted storybooks that shaped the children raised at Rose Mansion. His most infamous work, *The Nameless Monster*, became Johan's literal blueprint—the boy adopted both his name and his entire philosophy from its pages. Bonaparta's other notable stories included *The Big Eyed Man and the Big Mouthed Man*, *The God of Peace*, and *The Quiet Village*.
His writing style leaned heavily on metaphor and symbolism, with monsters serving as central figures. While his books explored humanity's capacity for both good and evil, they ultimately painted a bleak picture—less interested in redemption than in condemning human nature itself. It's this dark worldview, combined with the eugenics experiment, that made Bonaparta's influence so destructive.
