The Facility
In the early 1900s, an agreement was reached between many nations of the Earth. To free prison space and discourage crime, a facility in a remote location would be built and various criminals from each nation were to be sent to partake in a fight to the death. The victor would be pardoned of his crimes, and given a second chance at life. Owned and operated by a mysterious family owned pharmaceutical company throughout generations, the once quietly accepted secret has become a televised sport, and a way to push experimentation on humans. Participants are given "abilities" and have their physical potential unlocked and augmented. The victors are dubbed Champions by society, and are awarded more money they know what to do with. Decades of dogma and propaganda have enabled the masses to accept and even celebrate this cruelty in the name of justice and entertainment.
Our protagonist, an average woman living an average life, has her life upended when she is disproportionately sentenced to compete in the Game after committing a minor crime. She must learn to survive in a lawless hellhole, and soon finds that the dogma fed to her from a young age was false; there are too many others like her there.
But what about the others that have done heinous things?
What is it to kill? What is it to live? "What makes my life worth more than the people I killed?"
Existing in this place gives more questions and suffering than answers, and protagonist must navigate them all, or die trying.
