In the tenth year of the Gray Twilight, the wandering witch Amber was involved in the battle to destroy Silvermoon City. She exposed her herbs and prophecy abilities to save the orphan Lila, but attracted the fallen lord Karen, who was her childhood sweetheart and the leader of the Knights, but now he was eroded by the black fog but retained his consciousness. The two went from hostility to cooperation. On the way to find the "Star Ash Seed" to purify the black fog, they uncovered the truth of ten years ago: Amber's parents were not executed by the villagers because of her prophecy, but sacrificed to protect her and bear the crime of "evil witch".
