A Butterfly's Effect

You are a cultivator, a master of meditation, martial arts, and swordsmanship, sworn to your clan and in pursuit of justness and rightness in the world as you quest for the immortality granted to those who gain the benevolence of heaven. You are sent to uncover a legendary villain who is reputed to have hidden herself for years away in a remote village. Unfortunately, your target has concealed themselves well among the populace. How will you reveal the truth? What will the locals say? And who else searches for the villain? By the time you find her, will you be certain that you can - or should - bring her to justice?
