After defeating a hell demon, Quinn Valoran, God of War and Oaths, suffers severe injuries, loses his divine power and falls into the mortal world, working as a quarry labourer. His wife Molly betrays him with nobleman Edric. Stabbed by a sacred oath marked hairpin, Quinn regains his godhood memories. He meets his pre arranged fiancée Serena Claire. The pair get caught in noble power struggles: Lucas colludes with Morvath, a mortal stand in wearing Quinn’s sacred armor. The fake god misuses divine authority to seize resources and frame the Claire family. Quinn allies with Valkyrie Elsa and Dragon King Regnar to fight against oppression. At the grand triumph ceremony, Quinn retrieves his holy armor and spear, exposes the imposter, punishes Edric, Molly, Lucas and corrupt nobles. He reinforces sacred oaths, grants just rewards to loyal people, and marries Serena, crowning her the continent’s War Queen.
