Ys IV: Mask of the Sun

After having defeated the ultimate evil in his previous adventure in the magical land of Ys, the red-haired swordsman Adol Christin returned to the town of Minea. Suddenly, Adol notices a bottle, thrown onto the shore. It contains a letter, written in a foreign language, in which an unknown person asks Adol to come to the land of Celceta and save it from a mysterious evil. Adol decides to accept the offer, and thus his new adventure begins.
