Ludwig Heart, the heir to a vast fortune and a life of luxury, craves only one thing: freedom from his gilded cage. But when a plane crash catapults him into a world of magic and danger, he awakens not as the hero he dreamed of, but as a victim in a twisted ritual. Trapped between the ambitions of dark necromancers and the wrath of vengeful gods, Ludwig must navigate a deadly new reality where his life is no longer his own. Stripped of privilege and resurrected as an undead pawn, Ludwig’s fight for survival will determine whether he reclaims his destiny—or becomes a mere footnote in a world of shadows and deceit.
