Eventually, some of the survivors adapt to the existing situation and live only with their primal instincts and strong will to survive, and consider eating human flesh.
Human carcasses taste horrible, morality can’t feed their stomach anymore, and the idea of hunting another human being as food becomes a viable option; cannibalism starts to rise up, and people like these are called Ferals since they think and act like animals. The last generation before the catastrophic event that are still alive are called ‘The Last Gen’. According to them, the world has been divided into 3 factions; the Survivors, the Ferals, and the Bitewalkers. One particular Last Gen elder inside the camp tells a story about how a bitewalker once saved her life from being attacked by another bitewalker, but no one took her story seriously because of his advanced age.
