Hidden Intention
There was a story that has long disappeared from human civilization. The story of the fourth creature resembles a human, with perfection equal to an angel. This creature was created to fight the devils, to fight demons with their temptations.
When the creator knew humans were weak against temptation and they are so prone to sin, the Tsarqi appeared. A being that has no original sin, and will never fall into sin.
They spent their lives fighting the seven devils who represented the seven deadly sins, and the demons who spread those sins throughout the earth.
However, Tsarqi who spent too long on earth became weak and easily fell into temptation.
Those who have defiled their souls with sin are cast out of the glorious place and imprisoned in the desolate earth dimension. They can only see the world spinning and developing around them, but cannot be a part of it. This punishment can last for hundreds, even thousands, of years.
