Long ago, the world was peaceful calm all of humanity gathered together and created a great big city. They called Utopia it covered the whole world It was perfect. until the event happened

A strange putrid bloody fog spread across the world. It twisted most people, objects and thoughts into monsters their power destroyed sectors of the city the most disturbing part was that some of these monsters still have their consciousness, and sometimes the devour each other to become more powerful

The ones that didn’t get turned into monsters, mostly went to mad. luckily the people who weren’t affected by the frog were able to kill and contain most of these monsters. The influence of these monsters stuck around. From a sectors being twisted inside out, to a sectors twisting like music

After that day, the city was broken up into sections and rings The closer to 0/0 the center of the city the more dangerous the city was on a full lockdown meaning nothing get out of the city. The sane people kept to the 1000 ring and further sector and district

More powerful monsters need a constant stream of fog to keep living and don’t do well in areas with thinner less dense fog. Most monsters starting from ring 500 going inward start following my chain of command of sorts from understand human speech to serving monsters stronger than them and taking a less hemorrhoid form
