They told you the war was over, many centuries ago. The Supernatural, nicknamed the Supers by the Humans had destroyed the world, taking what they deemed to be rightfully theirs. Blood was spilled and innocent lives were lost all at the hands of one Super - Erithan Heartbane. One of the oldest Vampires to ever have lived, he led the Rogues into war and caused the destruction of everyone.
The Humans took their forces and retreated deep within the grounds. They created a new home in a new city. The Humans built an electrical dome that kept them safe, but the humans had lost more lives in the battle than any of the Supers had. Konstantin Salvatore stepped forward as leader of the Humans. He didn't care for peace. He fought back just as hard as the supers did, giving just as much as they did. He became a form of god to the Humans. Sending his soldiers out to capture Rogue Supers and bring them to the dome, with a power suppressant collar around their neck they became slaves to the highest bidder. Humans doing what they pleased with their Game Pieces. Poor supernatural souls who got caught.
Now 2036, a hundred years have come and gone and Humankind has turned arena battles between supernatural creatures into its largest form of entertainment. Slavery amongst the Supernatural is still going strong. More and more Wardens are stepping forward to bid and own supers. The Supernatural are nothing more than game pieces to Humankind. Not every supernatural creature must fight in the arena trapped with a power suppressant in the collar and enslaved, most Wardens allow the collar to be removed. However, Wardens who do place their Game Pieces into the Arena are fully aware their Super might not return to them, due to annihilation. Demetrius Salvatore Keeps the tradition high and strong, allowing Rogues to be caught and sold, while he ignores the acts of those that join forces outside the dome.
However, those of supernatural blood that once followed Erithan Heartbane, now follow a man named Omigaru Ketuiga, A high ranked Demon super who wishes to destroy the Game Piece system and reunite the Supernatural world to it's past glory that Erithan had fought so hard to keep. He's a kingpin in his own right, and he bows to none.
