Way of the heavenly demon

It is a religious group that originated from a Zoroastrian Church in Xinjiang that worshipped the Demon God and the Holy Fire and seeks the path of pursuing strength.

The Heavenly Demon (aka Tien Mo) clan is considered the hardest to enter a state of "disciple". The clan is reknowned for their range of saber techniques and "Bloody Hands" martial art. Their forms are of prowess combined with speed.

They must be corageous and talented enough to wield each and every technique handed down by The Emperor Heavenly Demon. They desecrate the symbol of Yin and Yang with Heavenly Demon's Sacred Fire. They emphasize Constitution and Essence, and use Kung Fu for offense and Chi Kung for defensive with equal skill
