History
Founding of Hokuto Shinken
The dynasty served the Tentei during the Han dynasty. 1800 years ago, the disappearance of the Emperor triggered turbulent times in China. This led the head priests to search for a successor to Hokuto Soke. During that time, there were no male successors of the Hokuto Soke, only two ladies, Shume and Oka. They soon gave birth to their own sons on the same day, Shuken and Ryuo. The priests decreed that there could be but one Denshōsha and that the two babies be placed on the holy Kōtendai (降天台) mountain dais and that the heavens would decide which child was to survive.
However, due to Shume's sickly predisposition, she disobeyed and rescued Shuken. After explaining her reason to her sister, Oka decide to choose Shuken as the successor of Hokuto Soke and for Shuken and Ryuo, she sacrificed herself by throwing herself off the cliff. This secured Shuken as the sole successor of Hokuto Soke who soon created Hokuto Shinken, thanks to the love of the two sisters that he received. Meanwhile, Ryuo chose his own destiny and formed Hokuto Ryuken, due to his lack of love in his life. Some of Ryuo's descendants would eventually become servants of the main Hokuto Soke dynasty.
