Hundreds of years ago, the Church launched the "War of Holy Judgment," claiming it was to maintain the balance of the elements. It wiped out the sword cultivators from the Eastern Continent and burned every text on the Way of the Sword. Li Fan's ancestors fled to a remote border village with the last treasure of the Way of the Sword, the "Sword of Unity." They concealed their identities and waited for the child of destiny to awaken the sword's true spirit.
