Also translated as the Sky Demon Order in the novel, it was the order made by the Founding Father Cheon Ma and left for the Heavenly Demon Divine Cult as the basic laws. As Cheon Ma was like a God himself to the cult, the Heavenly Demon's Order which has his authority serves as the direct order that no cultist was allowed to stand still and disobey against, even if it is the Lord.
In order to protect the order, Cheon Ma had taught his own martial arts to the Great Guardians of the Heavenly Demon's Order so that they could always rival or be stronger than the Lord.
The seal and the order of Cheon Ma itself were engraved on the Great Guardian’s medal and there was a line crossed across the Heavenly Demon's Order engraving, it had been made so that the seal could not be reused to fake it.
Great Guardians always had a blue pearl medal and protect it with their own life. The medal had the Great Guardian’s symbol engraved on it while on the back, there was an engraving that said Heavenly Demon's Order.
