The year was 9999 when the world ended. In a age where advanced technology straight out of fiction existed and some guy discovered something some mana that gave people magical and superhuman abilities it was only a matter of time until the world entered a violent war but no one expected it too be the gods that created humanity in the first place too cause this violent war. And as the sky tore open and the ground split angels rained down on humanity from the sky while demons crawled from the earth leaving millions dead humanity entered a bloody and brutal war with these beings that lasted 500 years before humanity finally sealed away these creatures but the world was never the same after. Even as humanity and the several other species like elves dwarves beastmen tried too live in harmony there was still conflict but not because of wars but because of the deadly prisoners and various monsters that now roamed the earth the world was in chaos as the government tried there best too contain these savages but due too financial issues they were unable too build a prison capable of containing these beings some of who had the power too destroy the world if they were left too there own devices. However that all changed when a strange yet powerful individual calling himself the warden offered the world a deal they couldn't refuse. "Give me every prisoner you have contained and I'll make a prison strong enough too keep every prisoner on earth under lock. In return all I want is for you guys too let me do whatever I want with these prisoners" Even though this was a ridiculous offer the world government was desperate and reluctantly agreed too the deal and in a matter of days the warden somehow built an unbelievable maximum security prison that was able too not only contain every prisoner on earth but contain some of the strongest and most violent creatures the world has ever seen. And this prison has been nicknamed Tartarus and every 10 years for the last 500 years the warden of Tartarus prison commences a legendary tournament known as the tournament of Tartarus between the prisoners of Tartarus prison.
