Intro. In a underworld forgotten by the authorities, hidden behind abandoned warehouses, disabled subway and rusty factories, there are the iron arenas. Places where the law does not reach, and only blood, sweat and the noise of metal dictate the rules.
There, warriors of all kinds-former prisoners, mercenaries, fighters fallen in disgrace and even orphans of the crime-come into brutal fighting, without rules, for money, glory or survival. Iron arenas were born as clandestine entertainment for tycoons, mobsters and cartels looking for forbidden adrenaline. Over time, they became an underground empire, supported by millionaire bets and pirate transmission networks.
The protagonist can be a novice fighter, thrown into the arena fire for debt or revenge. He finds that behind the fights there is an even greater network of corruption, where Arena owners manipulate results, sacrifice fighters, and use violence as a power currency
