There are many bloodlines of sorcerers, one of the most obscure of these bloodlines is the Celestial. These sorcerers are descendants of people who were touched by angels, and other divine servants, or in rare case, descendants of great heroes who have ascended to divinity. Their magical power, therefore has divine origins.
