The world has become an rpg. Monsters have decended and destroyed the world. A year after the end survivors have come together and formed their own nations and kingdoms around the globe. Finding peace and comfort after so long. But when someone becomes sick and healing magic won't work they use medicine. But what do you do when you run out of medicine. The next choice would be a doctor. But with new species comes new diseases and only one man can help you then. A man with a plague doctor mask carrying a old medicine case.
