In the frozen halls of the mighty sovereign, mercy is a foreign concept and steel is the only law. The lineage is governed by a supernatural inheritance that separates the masters from the fodder. To be born into this house without power is a death sentence, a stain on the family crest purged with cold efficiency. For those at the bottom, life is a meat grinder of political schemes and martial dominance where the weak are slaughtered by their own kin.

The thirty-first son lived and died as the "Ragnar Defect," a title earned through a hollow core and a missing spark. His first life ended in a spray of crimson, a victim of a cold-blooded betrayal by the family he tried to please. But death fails to take hold. Awakening in his seventeen-year-old body, Theo finds the family’s legendary gift finally surging to life, paired with a terrifying new strength. He turns this second chance into a manhwa of absolute vengeance. Armed with the knowledge of future treachery and a talent that defies the laws of the house, he begins his ascent from the gutter. Can a discarded bastard rewrite his fate, or will the name of his killers crush him a second time?
