It happened so suddenly. Monsters you see in video games and read in books suddenly showed up in the world. Every government fell almost instantly when they appeared. If normal weak monsters like goblins showed up first then bullets and missles would have done it. But what showed up in the beginning was dragons that flew through the air with scales that are harder than steel. Phoenix's with flames that could melt anything within a mile radius in seconds. Giant worms that would burrow underground and shoot up to swallow five people at once.

While on the sea krakens appeared and with them beings that would later be called leviathans. But the scary thing is where they appeared which is in almost every military base. They were destroyed in seconds like someone knew what they were doing when bringing these monsters to our world. Then came the slimes and giant animals. They tore through many people like paper. Their strength and ferociousness was something a normal person from modern earth could compete against. Thankfully we weren't totally left on our own. Humanity was given a weapon commonly called the system.

It would show a persons name, level, and their stats. When one first opens the system they will get a gift. The gift can range from a stick to armor that can repair itself to a staff that can fire magic. Of course only the really luck get things like that. Then the discovery of skill books was made which allowed people to learn different things. Once someone learns a skill they would understand it and can then teach it to other people. After about a month people started coming together and forming their own governments. There are also bandit groups here and there. As the months went by proper kingdoms were made with a king and nobles. They made farms, walls, and lived in buildings that are still standing after the monsters attacked. The human race were able to make a new life for itself. But problems once again emerged. Disease ran rampant due to shots no longer being administered and cleaning becoming more of a chore.

At first people with healing magic tried to cure all the diseases with their magic. But they learned that some diseases don't have such a simple solution. Then they used medicine where magic failed and for a time it worked. But supplies soon ran dry so everyone turned to former doctors. Not many survived after the attack but there was enough of them in every kingdom. But by then it was to late as new parasites and diseases which were riding on the monsters during their transfer were unleashed upon the world. They greatly confused the doctors and soon they had to admit to their powerlessness. Until a skill was soon made known. The alchemy skill which is said to hold the key to the new parasite came to be known.

At first no one cared for such a skill as they saw no need for it. But soon new plant species were being discovered every other day 6 months after the end. Some can be seen as nothing as grass while other can be a giant tree with a bright purple glow. Alchemists were now in demand but those that are currently learning alchemy were still new to the field. But in New York-Presbyterian Hospital/ Weill Cornell medical center resides the only man who has mastered alchemy. That would be me Vincent Hamilton more commonly known as the plague doctor.
