"If it's connected to Damien, it makes sense how he uses the element of light," Aqua said, doing some calculations in his head.
"Is there some other property of the light element?"
"There is an ancient belief that the element of light comes from the Sun God. According to legends, the Sun God sent a saint to choose his disciples. When the powers given to this saint are passed on to the Sun God's apostle, he can use the power of light."
"Why would the Sun God choose to send a saint to his apostle instead of giving him power directly?"
"There are various rumors about this. Some sources say it is because there is no direct way for him to transfer the power to his apostle. Others say that if the apostle receives the power directly, it could destroy his life."
