3000 Years ago, history is still known as the era of 2300 AD.
Human civilization has developed rapidly, especially in biogenetic science, human beings have made transcendental developments. You can already create creatures as you wish. After creating many strange species, people tried to challenge the legendary holy beast, the dragon. They attempted to replicate the dragon using the found dragon dace. This move angered the seven dragons that guarded the world. So the dragon began to take revenge on humans. Human beings are vulnerable to that kind of power beyond imagination.
At this time, four goddesses appeared.
They respectively represent the four greatest natural forces: time, life, darkness, and nothingness. They used all their strength to kill all seven dragons. The Dark Goddess buried the dragon's bones in an empty continent and sealed it with the continent. After doing all this, she herself died of exhaustion. At this time, the earth has been destroyed by the dragon and is riddled with holes. It even began to collapse and begin to disintegrate into the universe. The three remaining goddesses combined all their power to glue the earth back together. And turned the scattered continents into floating objects similar to asteroids.
The scattered continents later became the City of Floating Feathers, the Land of Ice and Snow, and the Continent of Europa.
