There is such a legend circulating in the distant land of Defaryana. There was an angel who had her wings taken away from her by a group of vicious people while she was performing a mission in the lower world.

"Since you are an angel, why don't you use your divine power to escape from this ghost place?". The angel smiled bitterly for a while and said. "We angels cannot harm you humans in the lower world."
