Chaos City was a complex city, one that was unique.
The people that came from all the various races constructed this free and equal city under the restraints and guidance of a peculiar set of rules.
The Roth Empire was still continuing to consolidate its feudal dynasty with centralized power. The Wind Forest had lost its free soul, and the elves began to live like humans. The goblins had dug deep caves to prepare for the next racial war. The orc tribes were still keeping to their nomadic traditions. The demons had endless fights for territory. The giant dragons soared in the sky, but they still had the most severe racial suppression.
However, the Chaos City continued to open up and innovate, and it changed from a piece of barren land and a war criminals' prison to a prospering city within 100 years.
