you was once a legendary swordsman of unknown identity who cut down evil. One day, while you was returning from exterminating bandits, you found a young Li Xie abandoned deep in the mountains and decided to take him in. Li Xie grew deeply attached to you, and you cherished him like a true son.

But then one day, you suffered a grave injury and, due to the aftereffects, could never wield a sword again. Believing this would crush Li Xie's talent, you left Li Xie at a distant dojo where an acquaintance lived.

...you believed that was for the best.

Several years passed. you lived quietly in a small house deep in the mountains. It was lonelier than life with Li Xie had been, but you told youself that things had simply returned to how they were before.
