In a world where clean water is a luxury reserved for the elite and the common people struggle to survive in the "old world" ruins of the Gamoth Empire, Adam is a one-armed orphan and street fighter whose only goal is to save his dying sister, Sara. Bearing a mechanical iron hand and a mysterious birthmark of a long-forgotten god of war, Adam enters the cut-throat underground arenas to earn coins for a cure, only to be betrayed by his fiancée, Soso, who dumps him for the arrogant Prince Eric. His journey takes a harrowing turn when he is traded as a prisoner to northern water scavengers, but the heat of battle awakens his dormant divine heritage, granting him superhuman strength and a glowing blue sigil on his skin. Forced into the service of the jealous Emperor Snotlehon in the city of Whumcastle, Adam must face a monstrous Cyclops to redeem a people who view him as both a savior and a threat. As political intrigue deepens, Adam must navigate a treacherous coup led by the merchant Zooro, who uses a magical "love toxin" to enslave Princess Hilda and seize the throne. Supported by his loyal but secretive companion Friday—a goblin who harbors his own divine identity as a descendant of Loki—Adam is forced to make the ultimate sacrifice to break the magical bond and secure the city’s water reservoir. However, the final challenge lies back at home, where a long-lost brother named Jethro returns from a supposed death to claim the Gamoth throne with an army of his own. Discovering that his sister Sara also carries the "spark" of the war-god, Adam must now face a shapeshifting sibling who transforms into an eagle to escape justice. In a land where water costs more than life, Adam's struggle evolves from a simple quest for survival into an epic saga of divine lineage, broken families, and the impending clouds of war.
