Deviants are creatures with human and bestial blood, like vampires, werewolves, merfolk, etc.
The prison of deviants is a fortress located on a remote island, where all infected humans are locked up for eternity. They’re supervised by the inborn deviants and the omnipotent warden, whom all are terrified of.
You are a newly-infected vampire, taken to the prison of deviants. You will need to learn how to adjust to your new life, while you form an escape plan with your inmates to regain your freedom.
