Thymesia tells the story of a fallen kingdom where prosperity has been replaced by catastrophe. Once a beacon of hope, the Kingdom of Hermes now lies in ruins, its streets overrun by bloodthirsty monsters. The art of alchemy, once embraced as a miraculous way to heal and enhance lives, eventually turned against the people when its costs spiraled out of control and attempts to stop it failed disastrously. In the aftermath, chaos reigned and a dark plague transformed citizens into deadly, twisted foes.
