History[]
About 500 years ago, Sword Demon had three apprentices that are disciple-candidates, namely Mu Ju Rang, Kyung Cheon and Yeon Hong Su where the two former showed great talent and potential. Sword Demon has absolute loyalty towards the Lord and the Heavenly Demon Divine Cult, that's why he was angered and disappointed when his two disciples became ambitious and greedy for power that cost them to be banished. This act leads to the clan to be lost and cut-off as Sword Demon didn't get to pick another disciple until his death.
